Effective Date\n\nThe licenses granted in Section 2.1 with respect to any Contribution\nbecome effective for each Contribution on the date the Contributor first\ndistributes such Contribution.\n\n2.3. Limitations on Grant Scope\n\nThe licenses granted in this Section 2 are the only rights granted under\nthis License. No additional rights or licenses will be implied from the\ndistribution or licensing of Covered Software under this License.\nNotwithstanding Section 2.1(b) above, no patent license is granted by a\nContributor:\n\n(a) for any code that a Contributor has removed from Covered Software;\n or\n\n(b) for infringements caused by: (i) Your and any other third party's\n modifications of Covered Software, or (ii) the combination of its\n Contributions with other software (except as part of its Contributor\n Version); or\n\n(c) under Patent Claims infringed by Covered Software in the absence of\n its Contributions.\n\nThis License does not grant any rights in the trademarks, service marks,\nor logos of any Contributor (except as may be necessary to comply with\nthe notice requirements in Section 3.4).\n\n2.4. Subsequent Licenses\n\nNo Contributor makes additional grants as a result of Your choice to\ndistribute the Covered Software under a subsequent version of this\nLicense (see Section 10.2) or under the terms of a Secondary License (if\npermitted under the terms of Section 3.3).\n\n2.5. Representation\n\nEach Contributor represents that the Contributor believes its\nContributions are its original creation(s) or it has sufficient rights\nto grant the rights to its Contributions conveyed by this License.\n\n2.6. Fair Use\n\nThis License is not intended to limit any rights You have under\napplicable copyright doctrines of fair use, fair dealing, or other\nequivalents.\n\n2.7. Conditions\n\nSections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted\nin Section 2.1.\n\n3. Responsibilities\n-------------------\n\n3.1. Distribution of Source Form\n\nAll distribution of Covered Software in Source Code Form, including any\nModifications that You create or to which You contribute, must be under\nthe terms of this License. You must inform recipients that the Source\nCode Form of the Covered Software is governed by the terms of this\nLicense, and how they can obtain a copy of this License. You may not\nattempt to alter or restrict the recipients' rights in the Source Code\nForm.\n\n3.2. Distribution of Executable Form\n\nIf You distribute Covered Software in Executable Form then:\n\n(a) such Covered Software must also be made available in Source Code\n Form, as described in Section 3.1, and You must inform recipients of\n the Executable Form how they can obtain a copy of such Source Code\n Form by reasonable means in a timely manner, at a charge no more\n than the cost of distribution to the recipient; and\n\n(b) You may distribute such Executable Form under the terms of this\n License, or sublicense it under different terms, provided that the\n license for the Executable Form does not attempt to limit or alter\n the recipients' rights in the Source Code Form under this License.\n\n3.3. Distribution of a Larger Work\n\nYou may create and distribute a Larger Work under terms of Your choice,\nprovided that You also comply with the requirements of this License for\nthe Covered Software. If the Larger Work is a combination of Covered\nSoftware with a work governed by one or more Secondary Licenses, and the\nCovered Software is not Incompatible With Secondary Licenses, this\nLicense permits You to additionally distribute such Covered Software\nunder the terms of such Secondary License(s), so that the recipient of\nthe Larger Work may, at their option, further distribute the Covered\nSoftware under the terms of either this License or such Secondary\nLicense(s).\n\n3.4. Notices\n\nYou may not remove or alter the substance of any license notices\n(including copyright notices, patent notices, disclaimers of warranty,\nor limitations of liability) contained within the Source Code Form of\nthe Covered Software, except that You may alter any license notices to\nthe extent required to remedy known factual inaccuracies.\n\n3.5. Application of Additional Terms\n\nYou may choose to offer, and to charge a fee for, warranty, support,\nindemnity or liability obligations to one or more recipients of Covered\nSoftware. However, You may do so only on Your own behalf, and not on\nbehalf of any Contributor. You must make it absolutely clear that any\nsuch warranty, support, indemnity, or liability obligation is offered by\nYou alone, and You hereby agree to indemnify every Contributor for any\nliability incurred by such Contributor as a result of warranty, support,\nindemnity or liability terms You offer. You may include additional\ndisclaimers of warranty and limitations of liability specific to any\njurisdiction.\n\n4. Inability to Comply Due to Statute or Regulation\n---------------------------------------------------\n\nIf it is impossible for You to comply with any of the terms of this\nLicense with respect to some or all of the Covered Software due to\nstatute, judicial order, or regulation then You must: (a) comply with\nthe terms of this License to the maximum extent possible; and (b)\ndescribe the limitations and the code they affect. Such description must\nbe placed in a text file included with all distributions of the Covered\nSoftware under this License. Except to the extent prohibited by statute\nor regulation, such description must be sufficiently detailed for a\nrecipient of ordinary skill to be able to understand it.\n\n5. Termination\n--------------\n\n5.1. The rights granted under this License will terminate automatically\nif You fail to comply with any of its terms. However, if You become\ncompliant, then the rights granted under this License from a particular\nContributor are reinstated (a) provisionally, unless and until such\nContributor explicitly and finally terminates Your grants, and (b) on an\nongoing basis, if such Contributor fails to notify You of the\nnon-compliance by some reasonable means prior to 60 days after You have\ncome back into compliance. Moreover, Your grants from a particular\nContributor are reinstated on an ongoing basis if such Contributor\nnotifies You of the non-compliance by some reasonable means, this is the\nfirst time You have received notice of non-compliance with this License\nfrom such Contributor, and You become compliant prior to 30 days after\nYour receipt of the notice.\n\n5.2. If You initiate litigation against any entity by asserting a patent\ninfringement claim (excluding declaratory judgment actions,\ncounter-claims, and cross-claims) alleging that a Contributor Version\ndirectly or indirectly infringes any patent, then the rights granted to\nYou by any and all Contributors for the Covered Software under Section\n2.1 of this License shall terminate.\n\n5.3. In the event of termination under Sections 5.1 or 5.2 above, all\nend user license agreements (excluding distributors and resellers) which\nhave been validly granted by You or Your distributors under this License\nprior to termination shall survive termination.\n\n************************************************************************\n* *\n* 6. Disclaimer of Warranty *\n* ------------------------- *\n* *\n* Covered Software is provided under this License on an \"as is\" *\n* basis, without warranty of any kind, either expressed, implied, or *\n* statutory, including, without limitation, warranties that the *\n* Covered Software is free of defects, merchantable, fit for a *\n* particular purpose or non-infringing. The entire risk as to the *\n* quality and performance of the Covered Software is with You. *\n* Should any Covered Software prove defective in any respect, You *\n* (not any Contributor) assume the cost of any necessary servicing, *\n* repair, or correction.

No use of any Covered Software is *\n* authorized under this License except under this disclaimer. *\n* *\n************************************************************************\n\n************************************************************************\n* *\n* 7. Limitation of Liability *\n* -------------------------- *\n* *\n* Under no circumstances and under no legal theory, whether tort *\n* (including negligence), contract, or otherwise, shall any *\n* Contributor, or anyone who distributes Covered Software as *\n* permitted above, be liable to You for any direct, indirect, *\n* special, incidental, or consequential damages of any character *\n* including, without limitation, damages for lost profits, loss of *\n* goodwill, work stoppage, computer failure or malfunction, or any *\n* and all other commercial damages or losses, even if such party *\n* shall have been informed of the possibility of such damages. This *\n* limitation of liability shall not apply to liability for death or *\n* personal injury resulting from such party's negligence to the *\n* extent applicable law prohibits such limitation. Some *\n* jurisdictions do not allow the exclusion or limitation of *\n* incidental or consequential damages, so this exclusion and *\n* limitation may not apply to You. *\n* *\n************************************************************************\n\n8. Litigation\n-------------\n\nAny litigation relating to this License may be brought only in the\ncourts of a jurisdiction where the defendant maintains its principal\nplace of business and such litigation shall be governed by laws of that\njurisdiction, without reference to its conflict-of-law provisions.\nNothing in this Section shall prevent a party's ability to bring\ncross-claims or counter-claims.\n\n9. Miscellaneous\n----------------\n\nThis License represents the complete agreement concerning the subject\nmatter hereof. If any provision of this License is held to be\nunenforceable, such provision shall be reformed only to the extent\nnecessary to make it enforceable. Any law or regulation which provides\nthat the language of a contract shall be construed against the drafter\nshall not be used to construe this License against a Contributor.\n\n10. Versions of the License\n---------------------------\n\n10.1. New Versions\n\nMozilla Foundation is the license steward. Except as provided in Section\n10.3, no one other than the license steward has the right to modify or\npublish new versions of this License. Each version will be given a\ndistinguishing version number.\n\n10.2. Effect of New Versions\n\nYou may distribute the Covered Software under the terms of the version\nof the License under which You originally received the Covered Software,\nor under the terms of any subsequent version published by the license\nsteward.\n\n10.3. Modified Versions\n\nIf you create software not governed by this License, and you want to\ncreate a new license for such software, you may create and use a\nmodified version of this License if you rename the license and remove\nany references to the name of the license steward (except to note that\nsuch modified license differs from this License).\n\n10.4. Distributing Source Code Form that is Incompatible With Secondary\nLicenses\n\nIf You choose to distribute Source Code Form that is Incompatible With\nSecondary Licenses under the terms of this version of the License, the\nnotice described in Exhibit B of this License must be attached.\n\nExhibit A - Source Code Form License Notice\n-------------------------------------------\n\n This Source Code Form is subject to the terms of the Mozilla Public\n License, v. 2.0.

Currently adding components is supported on Scenes, Objects, Bones, and Materials.\n\n\n\nClick \"Add Component\" and select the component you wish to add from the list. Only components appropriate for the object type you are currently editing and have not already been added will be shown.\n\n# Using Lightmaps\n\nTo use a lightmap, create a `MOZ_lightmap` node from the `Add > Hubs` menu and hook up a image texture to the `Lightmap` input. Use a `UV Map` node to control what UV set should be used for the lightmap, as you would any other texture in Blender.\n\n![lightmap node](https://user-images.githubusercontent.com/130735/83931408-65c7bd80-a751-11ea-86b9-a2ae889ec5df.png)\n\nNote that for use in Hubs, you currently **MUST** use the second UV set, as ThreeJS is currently hardcoded to use that for lightmaps. This will likely be fixed in the future so the add-on does not enforce this.\n\n![setting bake UV](https://user-images.githubusercontent.com/130735/83697782-b9e96b00-a5b4-11ea-986b-6690c69d8a3f.png)\n\n# Exporting\n\nThis addon works in conjunction with the official glTF add-on, so exporting is done through it. Select \"File > Export > glTF 2.0\" and then ensure \"Hubs Components\" is enabled under \"Extensions\".\n\n![gltf export window](https://user-images.githubusercontent.com/130735/84547591-be9ad700-acb8-11ea-8c58-7b1104f0a3a7.png)\n\n# Import into Hubs\n\nThe easiest way to use your scene file is through the Spoke project creation page and selecting _Import From Blender_:\n\n\"Screenshot\n\nThis will bring up the Publish Scene From Blender dialog where you can upload your GLB file and a thumbnail picture for your scene:\n\n\"Screenshot\n\nIt is also possible to use the GLB file to replace the scene for an existing Hubs room directly by going to Room Settings > Change Scene > Custom Scene and entering the URL of the GLB file. This assumes the file has been already uploaded to an online storage provider.\n\n# Scene debugger\n\nThe Hubs Blender add-on includes a scene debugger, enabling you to see the Blender scene updates in Hubs with just one click. For additional information, please visit: https://github.com/Hubs-Foundation/hubs-blender-exporter/wiki/Hubs-scene-debugger/\n\n# Development\n\n## Code Completion\nTo enable code completion for the Blender Python API you can install the [Fake Blender Python API module collection](https://github.com/nutti/fake-bpy-module/). You can download the modules using the `setup.sh` script from the repository root or using [pip](https://github.com/nutti/fake-bpy-module/#install-via-pip-package).\n## Code style\n\nThis repository follows the [PEP8](https://peps.python.org/pep-0008/) style convention for python files. If you use VSCode this repository already includes a setting to autoformat every python file when saved. If you don't use VSCode you can probably add a similar setting in your favorite editor. We are happy to add settings for other editors so feel free to open a PR if you want your editor's settings included.\n\nWe also include a `format.py` python script that will format the whole codebase when run. You can run it before pushing the PR to make sure that all the new code follows PEP8.\n\nBoth the python script and the VSCode settings rely on the [autopep8](https://pypi.org/project/autopep8/) command line tool for formatting so make sure that it's installed in your system.\n\n## Addon development\n\nIt might be useful while developing to be able to load the addon directly from the checkout folder without needing to install it. You can do it in two ways:\n\n- ### Overriding the Blender user scripts directory\n You can override the Blender user scripts directory from the console to point to the addon repo directory.\n\n**MacOS**\n\n`BLENDER_USER_SCRIPTS=full_path_to_/hubs-blender-exporter /Applications/Blender.app/Contents/MacOS/Blender`\n\n**Linux**\n\n`BLENDER_USER_SCRIPTS=full_path_to_/hubs-blender-exporter blender`\n\n- ### Symlinking your addon to the Blender user scripts directory\n You can create a symbolic link pointing to `full_path_to_/hubs-blender-exporter/addons/io_hubs_addon` in your current Python scripts directory in Blender. This way you will also load any other addons that you have in that directory.\n\n**MacOS and Linux**\n\n`ln -s full_path_to/hubs-blender-exporter/addons/io_hubs_addon full_path_to/blender_user_scripts_dir`\n\nYou can set or see the current Blender user scripts in the Preferences -> File Paths -> Scripts\n\n## Component export hooks\n\nWhen adding or modifying Hubs components, the exporter lifecycle uses a few different hooks with different responsibilities (these are defined in hubs_component.py and optionally overridden in specific components):\n\n- `pre_export`\n - Runs before export starts.\n - Best used for export setup or preprocessing that must happen before gathering data.\n - Avoid using this for component data validation that is tied to exported output.\n\n- `gather`\n - Runs when component data is exported.\n - Best place for component-specific export logic and export-time validation related to exported data.\n\n- `post_export`\n - Runs after export finishes.\n - Best used for cleanup or restoring temporary state.\n\nFor user-facing validation or reporting, prefer the existing Hubs report viewer / export reporting flow rather than console-only warnings when appropriate.\n\n# Debugging\n\nYou can debug the addon code with PyCharm or VSCode:\n\n- [Debug with PyCharm](https://code.blender.org/2015/10/debugging-python-code-with-pycharm) **NOTE:** If you are using Blender 2.80+, you need the [updated debugger script](https://github.com/ux3d/random-blender-addons/blob/master/remote_debugger.py)\n- [Debug with VSCode](DEBUGGING.md)\n\n# Continuous Integration Tests\n\nTo run the tests locally, your system should have a blender executable in the path that launches the desired version of Blender.\n\nThe latest version of [Yarn](https://yarnpkg.com/en/) should also be installed.\n\nThen, in the tests folder of this repository, run yarn install, followed by yarn run test.\n" }, { "path": "addons/io_hubs_addon/.pylintrc", "content": "[MASTER]\n\n# A comma-separated list of package or module names from where C extensions may\n# be loaded.

Here are the guidelines we'd like you to follow:\n\n - [Code of Conduct](#coc)\n - [Question or Problem?](#question)\n - [Issues and Bugs](#issue)\n - [Feature Requests](#feature)\n - [Submission Guidelines](#submission-guidelines)\n - [Git Commit Guidelines](#git-commit-guidelines)\n\n## Code of Conduct\nThis project adheres to the [Open Code of Conduct][code-of-conduct].\nBy participating, you are expected to honor this code.\n\n## Got a Question or Problem?\n\nIf you have questions about how to use Recast or Detour, please direct these to the [Google Group][groups]\ndiscussion list. We are also available on [Gitter][gitter].\n\n## Found an Issue?\nIf you find a bug in the source code or a mistake in the documentation, you can help us by\nsubmitting an issue to our [GitHub Repository][github]. Even better you can submit a Pull Request\nwith a fix.\n\n**Please see the Submission Guidelines below**.\n\n## Want a Feature?\nYou can request a new feature by submitting an issue to our [GitHub Repository][github]. If you\nwould like to implement a new feature then consider what kind of change it is:\n\n* **Major Changes** that you wish to contribute to the project should be discussed first on our\n[Google Group][groups] or in [GitHub Issues][github-issues] so that we can better coordinate our efforts, prevent\nduplication of work, and help you to craft the change so that it is successfully accepted into the\nproject.\n* **Small Changes** can be crafted and submitted to the [GitHub Repository][github] as a Pull Request.\n\n## Submission Guidelines\n\n### Submitting an Issue\nBefore you submit your issue search the [GitHub Issues][github-issues] archive,\nmaybe your question was already answered.\n\nIf your issue appears to be a bug, and hasn't been reported, open a new issue.\nHelp us to maximize the effort we can spend fixing issues and adding new\nfeatures, by not reporting duplicate issues. Providing the following information will increase the\nchances of your issue being dealt with quickly:\n\n* **Overview of the Issue** - what type of issue is it, and why is it an issue for you?\n* **Callstack** - if it's a crash or other runtime error, a callstack will help diagnosis\n* **Screenshots** - for navmesh generation problems, a picture really is worth a thousand words.\n Implement `duDebugDraw` and call some methods from DetourDebugDraw.h. Seriously, just do it, we'll definitely ask you to if you haven't!\n* **Logs** - stdout and stderr from the console, or log files if there are any.\n If integrating into your own codebase, be sure to implement the log callbacks in `rcContext`.\n* **Reproduction steps** - a minimal, unambigious set of steps including input, that causes the error for you.\n e.g. input geometry and settings you can use to input into RecastDemo to get it to fail.\n\tNote: These can be saved by pressing the 9 key in RecastDemo, and the resulting .gset file can be shared (with the .obj if it is not one of the default ones).\n* **Recast version(s) and/or git commit hash** - particularly if you can find the point at which the error first started happening\n* **Environment** - operating system, compiler etc.\n* **Related issues** - has a similar issue been reported before?\n* **Suggest a Fix** - if you can't fix the bug yourself, perhaps you can point to what might be\n causing the problem (line of code or commit)\n\nHere is a great example of a well defined issue: https://github.com/recastnavigation/recastnavigation/issues/12\n\n**If you get help, help others. Good karma rulez!**\n\n### Submitting a Pull Request\nBefore you submit your pull request consider the following guidelines:\n\n* Search [GitHub Pull Requests][github-pulls] for an open or closed Pull Request\n that relates to your submission. You don't want to duplicate effort.\n* Make your changes in a new git branch:\n\n ```shell\n git checkout -b my-fix-branch master\n ```\n\n* Implement your changes, **including appropriate tests if appropriate/possible**.\n* Commit your changes using a descriptive commit message that follows our\n [commit message conventions](#commit-message-format).\n\n ```shell\n git commit -a\n ```\n Note: the optional commit `-a` command line option will automatically \"add\" and \"rm\" edited files.\n\n* Squash any work-in-progress commits (by rebasing) to form a series of commits that make sense individually.\n Ideally the pull request will be small and focused enough that it fits sensibly in one commit.\n\n ```shell\n git rebase -i origin/master\n ```\n\n* Push your branch to GitHub:\n\n ```shell\n git push origin my-fix-branch\n ```\n\n* In GitHub, send a pull request to `recastnavigation:master`.\n* If we suggest changes then:\n * Make the required updates.\n * Commit your changes to your branch (e.g. `my-fix-branch`).\n * Squash the changes, overwriting history in your fix branch - we don't want history to include incomplete work.\n * Push the changes to your GitHub repository (this will update your Pull Request).\n\nIf you have rebased to squash commits together, you will need to force push to update the PR:\n\n ```shell\n git rebase master -i\n git push origin my-fix-branch -f\n ```\n\nThat's it! Thank you for your contribution!\n\n#### After your pull request is merged\n\nAfter your pull request is merged, you can safely delete your branch and pull the changes\nfrom the main (upstream) repository:\n\n* Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:\n\n ```shell\n git push origin --delete my-fix-branch\n ```\n\n* Check out the master branch:\n\n ```shell\n git checkout master -f\n ```\n\n* Delete the local branch:\n\n ```shell\n git branch -D my-fix-branch\n ```\n\n* Update your master with the latest upstream version:\n\n ```shell\n git pull --ff upstream master\n ```\n\n## Git Commit Guidelines\n\n### Commit content\n\nDo your best to factor commits appropriately, i.e not too large with unrelated\nthings in the same commit, and not too small with the same small change applied N\ntimes in N different commits. If there was some accidental reformatting or whitespace\nchanges during the course of your commits, please rebase them away before submitting\nthe PR.\n\n### Commit Message Format\nPlease format commit messages as follows (based on this [excellent post](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)):\n\n```\nSummarize change in 50 characters or less\n\nProvide more detail after the first line. Leave one blank line below the\nsummary and wrap all lines at 72 characters or less.\n\nIf the change fixes an issue, leave another blank line after the final\nparagraph and indicate which issue is fixed in the specific format\nbelow.\n\nFix #42\n```\n\nImportant things you should try to include in commit messages include:\n* Motivation for the change\n* Difference from previous behaviour\n* Whether the change alters the public API, or affects existing behaviour significantly\n\n\n\n[code-of-conduct]: http://todogroup.org/opencodeofconduct/#Recastnavigation/b.hymers@gmail.com\n[github]: https://github.com/recastnavigation/recastnavigation\n[github-issues]: https://github.com/recastnavigation/recastnavigation/issues\n[github-pulls]: https://github.com/recastnavigation/recastnavigation/pulls\n[gitter]: https://gitter.im/recastnavigation/chat\n[groups]: https://groups.google.com/forum/?fromgroups#!forum/recastnavigation\n" }, { "path": "third_parties/recast/recast/License.txt", "content": "Copyright (c) 2009 Mikko Mononen memon@inside.org\n\nThis software is provided 'as-is', without any express or implied\nwarranty.

The process consists of three steps, \nbuilding the voxel mold, partitioning the mold into simple regions, peeling off \nthe regions as simple polygons.\n\n1. The voxel mold is built from the input triangle mesh by rasterizing the triangles into a multi-layer heightfield. Some simple filters are then applied to the mold to prune out locations where the character would not be able to move.\n2. The walkable areas described by the mold are divided into simple overlayed 2D regions. The resulting regions have only one non-overlapping contour, which simplifies the final step of the process tremendously.\n3. The navigation polygons are peeled off from the regions by first tracing the boundaries and then simplifying them. The resulting polygons are finally converted to convex polygons which makes them perfect for pathfinding and spatial reasoning about the level. \n\n\n## Detour\n\nRecast is accompanied with Detour, path-finding and spatial reasoning toolkit. You can use any navigation mesh with Detour, but of course the data generated with Recast fits perfectly.\n\nDetour offers simple static navigation mesh which is suitable for many simple cases, as well as tiled navigation mesh which allows you to plug in and out pieces of the mesh. The tiled mesh allows you to create systems where you stream new navigation data in and out as the player progresses the level, or you may regenerate tiles as the world changes. \n\n\n## Recast Demo\n\nYou can find a comprehensive demo project in RecastDemo folder. It is a kitchen sink demo containing all the functionality of the library. If you are new to Recast & Detour, check out [Sample_SoloMesh.cpp](/RecastDemo/Source/Sample_SoloMesh.cpp) to get started with building navmeshes and [NavMeshTesterTool.cpp](/RecastDemo/Source/NavMeshTesterTool.cpp) to see how Detour can be used to find paths.\n\n### Building RecastDemo\n\nRecastDemo uses [premake5](http://premake.github.io/) to build platform specific projects. Download it and make sure it's available on your path, or specify the path to it.\n\n#### Linux\n\n- Install SDL2 and its dependencies according to your distro's guidelines.\n- run `premake5 gmake` from the `RecastDemo` folder.\n- `cd Build/gmake` then `make`\n- Run `RecastDemo\\Bin\\RecastDemo`\n\n#### OSX\n\n- Grab the latest SDL2 development library dmg from [here](https://www.libsdl.org/download-2.0.php) and place `SDL2.framework` in `/Library/Frameworks/`\n- Navigate to the `RecastDemo` folder and run `premake5 xcode4`\n- Open `Build/xcode4/recastnavigation.xcworkspace`\n- Select the \"RecastDemo\" project in the left pane, go to the \"BuildPhases\" tab and expand \"Link Binary With Libraries\"\n- Remove the existing entry for SDL2 (it should have a white box icon) and re-add it by hitting the plus, selecting \"Add Other\", and selecting `/Library/Frameworks/SDL2.framework`. It should now have a suitcase icon.\n- Set the RecastDemo project as the target and build.\n\n#### Windows\n\n- Grab the latest SDL2 development library release from [here](https://www.libsdl.org/download-2.0.php) and unzip it `RecastDemo\\Contrib`. Rename the SDL folder such that the path `RecastDemo\\Contrib\\SDL\\lib\\x86` is valid.\n- Run `\"premake5\" vs2015` from the `RecastDemo` folder\n- Open the solution, build, and run.\n\n### Running Unit tests\n\n- Follow the instructions to build RecastDemo above. Premake should generate another build target called \"Tests\".\n- Build the \"Tests\" project. This will generate an executable named \"Tests\" in `RecastDemo/Bin/`\n- Run the \"Tests\" executable. It will execute all the unit tests, indicate those that failed, and display a count of those that succeeded.\n\n## Integrating with your own project\n\nIt is recommended to add the source directories `DebugUtils`, `Detour`, `DetourCrowd`, `DetourTileCache`, and `Recast` into your own project depending on which parts of the project you need. For example your level building tool could include `DebugUtils`, `Recast`, and `Detour`, and your game runtime could just include `Detour`.\n\n## Contributing\n\nSee the [Contributing document](CONTRIBUTING.md) for guidelines for making contributions.\n\n## Discuss\n\n- Discuss Recast & Detour: http://groups.google.com/group/recastnavigation\n- Development blog: http://digestingduck.blogspot.com/\n\n## License\n\nRecast & Detour is licensed under ZLib license, see License.txt for more information.\n" }, { "path": "third_parties/recast/recast/Recast/CMakeLists.txt", "content": "file(GLOB SOURCES Source/*.cpp)\n\nif (RECASTNAVIGATION_STATIC)\n add_library(Recast STATIC ${SOURCES})\nelse ()\n add_library(Recast SHARED ${SOURCES})\nendif ()\n\nadd_library(RecastNavigation::Recast ALIAS Recast)\n\nset(Recast_INCLUDE_DIR \"${CMAKE_CURRENT_SOURCE_DIR}/Include\")\n\ntarget_include_directories(Recast PUBLIC\n \"$\"\n)\n\nset_target_properties(Recast PROPERTIES\n SOVERSION ${SOVERSION}\n VERSION ${VERSION}\n )\n\ninstall(TARGETS Recast\n ARCHIVE DESTINATION lib\n LIBRARY DESTINATION lib\n COMPONENT library\n )\n\nfile(GLOB INCLUDES Include/*.h)\ninstall(FILES ${INCLUDES} DESTINATION include)\n" }, { "path": "third_parties/recast/recast/Recast/Include/Recast.h", "content": "//\n// Copyright (c) 2009-2010 Mikko Mononen memon@inside.org\n//\n// This software is provided 'as-is', without any express or implied\n// warranty.
