# Engine Simulator
---
# Engine Simulator has moved!
To get the newest releases of the game, [click here](https://github.com/Engine-Simulator/engine-sim-community-edition).
---
## What is this?
This is a real-time internal combustion engine simulation **designed specifically to produce engine audio and simulate engine response characteristics.** It is NOT a scientific tool and cannot be expected to provide accurate figures for the purposes of engineering or engine tuning.
## How do I install it?
This is a code repository and might not look like other software that you're used to downloading and installing (if you're not familiar with programming). To download a ready-to-use version of the application, navigate to the [releases page](https://github.com/ange-yaghi/engine-sim/releases), find the most recent release (ex. `v0.1.5a`), click "Assets" and download the .zip file with a name that starts with `engine-sim-build`. Unzip this file, then run `bin/engine-sim-app.exe`. The simulator should then start normally.
Check out [our Frequently Asked Questions](https://github.com/ange-yaghi/engine-sim/wiki/Frequently-Asked-Questions) if you need more details.
## How do I use it?
The UI is extremely minimalistic and there are only a few controls used to interact with the engine:
| Key/Input | Action |
| :---: | :---: |
| A | Toggle ignition |
| S | Hold for starter |
| D | Enable dyno |
| H | Enable RPM hold (see below for instructions) |
| G + Scroll | Change hold speed |
| F | Enter fullscreen mode |
| I | Display dyno stats in the information panel |
| Shift | Clutch (hold spacebar at the same time to slowly engage/disengage) |
| Up Arrow | Up Gear |
| Down Arrow | Down Gear |
| Z + Scroll | Volume |
| X + Scroll | Convolution Level |
| C + Scroll | High frequency gain |
| V + Scroll | Low frequency noise |
| B + Scroll | High frequency noise |
| N + Scroll | Simulation frequency |
| M | Increase view layer |
| , | Decrease view layer |
| Enter | Reload engine script |
| Escape | Exit the program |
| Q, W, E, R | Change throttle position |
| Space + Scroll | Fine throttle adjustment |
| 1, 2, 3, 4, 5 | Simulation time warp |
| Tab | Change screen |
### Using the RPM hold
The RPM hold feature will hold the engine at a specific RPM and also measure the engine's horsepower and torque at that RPM. You can enable RPM hold by pressing the `H` key. **You must then enable the dynomometer** (press the `D` key) in order for the RPM hold to take effect. To change the hold speed, hold the `G` key and scroll with the mouse wheel. The RPM hold will be shown on the `DYNO. SPEED` gauge in the lower left of the screen.
## Why is the code so sloppy?
I wrote this to demo in a [YouTube video](https://youtu.be/RKT-sKtR970), not as a real product. If you would like it to become a usable product please reach out to me or join my Discord (link can be found in the description of the aforementioned YouTube video). I use this codebase for my own purposes and so it might change frequently and without warning.
## How do I build it? (Ignore this section if you're not a developer!)
**Note: this project currently only builds on Windows!**
### Step 1 - Clone the repository
```git clone --recurse-submodules https://github.com/ange-yaghi/engine-sim```
### Step 2 - Install CMake
Install the latest version of CMake [here](https://cmake.org/) if it's not already installed.
### Step 3 - Install Dependencies
You will need to install the following dependencies and CMake will need to be able to locate them (ie. they need to be listed on your PATH):
1. SDL2
2. SDL2_image
3. Boost (make sure to build the optional dependencies)
4. Flex and Bison
### Step 4 - Build and Run
From the root directory of the project, run the following commands:
```
mkdir build
cd build
cmake ..
cmake --build .
```
If these steps are successful, a Visual Studio solution will be generated in ```build```. You can open this project with Visual Studio and then run the ```engine-sim-app``` project. If you encounter an error telling you that you're missing DLLs, you will have to copy those DLLs to your EXE's directory.
