# 1. Introduction
|
|
|
|
**OpenRCT2** is an open-source re-implementation of RollerCoaster Tycoon 2 (RCT2). The gameplay revolves around building and maintaining an amusement park containing attractions, shops and facilities. The player must try to make a profit and maintain a good park reputation whilst keeping the guests happy. OpenRCT2 allows for both scenario and sandbox play. Scenarios require the player to complete a certain objective in a set time limit whilst sandbox allows the player to build a more flexible park with optionally no restrictions or finance.
|
|
|
|
RollerCoaster Tycoon 2 was originally written by Chris Sawyer in x86 assembly and is the sequel to RollerCoaster Tycoon. The engine was based on Transport Tycoon, an older game which also has an equivalent open-source project, [OpenTTD](https://openttd.org). OpenRCT2 attempts to provide everything from RCT2 as well as many improvements and additional features, some of these include support for modern platforms, an improved interface, improved guest and staff AI, more editing tools, increased limits, and cooperative multiplayer. It also re-introduces mechanics from RollerCoaster Tycoon that were not present in RollerCoaster Tycoon 2. Some of those include; mountain tool in-game, the *"have fun"* objective, launched coasters (not passing-through the station) and several buttons on the toolbar.

## 3.2 Compiling and running
|
|
### Windows:
|
|
<details>
|
|
<summary>Show instructions</summary>
|
|
|
|
1. Check out the repository, this can be done using [GitHub Desktop](https://desktop.github.com) or [other tools](https://help.github.com/articles/which-remote-url-should-i-use)
|
|
2. Open a new Developer Command Prompt for VS 2022
|
|
3. Navigate to the repository (e.g. `cd C:\GitHub\OpenRCT2`)
|
|
4. To build the x64 version, use `msbuild openrct2.proj /t:build /p:platform=x64`
|
|
To build the x86 version, use `msbuild openrct2.proj /t:build /p:platform=Win32`
|
|
To build the Arm64 version, use `msbuild openrct2.proj /t:build /p:platform=arm64`
|
|
|
|
**Note:** The file `g2.dat` may not be generated on cross-compilation (e.g. building for Arm64 on a x64 machine). In this case `g2.dat` must be copied from a x86/x64 build.
|
|
5. Run the game, `bin\openrct2`
|
|
|
|
Once you have ran msbuild once, further development can be done within Visual Studio by opening `openrct2.sln`. Make sure to select the correct target platform for which you ran the build in point #3 (`Win32` for the x86 version, `x64` for the x64 version, `arm64` for the Arm64 version), otherwise the build will fail in Visual Studio.
|
|
|
|
Other examples:
|
|
```
|
|
set platform=x64
|
|
msbuild openrct2.proj /t:clean
|
|
msbuild openrct2.proj /t:rebuild /p:configuration=release
|
|
msbuild openrct2.proj /t:g2
|
|
msbuild openrct2.proj /t:PublishPortable
|
|
```
|
|
</details>
|
|
|
|
### macOS:
|
|
<details>
|
|
<summary>Show instructions</summary>
|
|
|
|
CMake can build either a self-contained application bundle, which includes all the necessary game files and dependencies, or it can build a command line version that links against system installed dependencies. CMake will retrieve the dependencies from [Dependencies](https://github.com/OpenRCT2/Dependencies/) automatically. You can build the macOS app using CMake using the following commands:
|
|
```
|
|
cmake -S . -B build
|
|
cmake --build build --target install
|
|
```
|
|
Then you can run the game by opening `OpenRCT2.app`
|
|
|
|
To build the command line version, you'll need to disable the macOS app bundle:
|
|
```
|
|
|
|
cmake -S . -B build -DMACOS_BUNDLE=off
|
|
cmake --build build
|
|
cmake --build build --target install
|
|
ln -s ../data data
|
|
```
|
|
Then you can run the game by running `./openrct2`.
|
|
|
|
To link against system dependencies instead of letting CMake download the dependencies from [Dependencies](https://github.com/OpenRCT2/Dependencies), add `-DMACOS_USE_DEPENDENCIES=off` to your cmake args.
|
|
|
|
Detailed instructions can be found on [Building OpenRCT2 on macOS using CMake](https://github.com/OpenRCT2/OpenRCT2/wiki/Building-OpenRCT2-on-macOS-using-CMake).
|
|
</details>
|
|
|
|
### Linux:
|
|
<details>
|
|
<summary>Show instructions</summary>
|
|
|
|
The standard CMake build procedure is to install the [required libraries](https://github.com/OpenRCT2/OpenRCT2#linux), then:
|
|
```
|
|
cmake -S . -B build -DCMAKE_INSTALL_PREFIX=. # set your standard cmake options, e.g. build type here - For example, -DCMAKE_BUILD_TYPE=RelWithDebInfo
|
|
cmake --build build # you can parallelise your build job with e.g. -j 8 or consider using ninja
|
|
cmake --build build --target install # the install target creates all the necessary files in places we expect them
|
|
```
|
|
|
|
You can also use Ninja in place of Make using `-G Ninja` in the first command, if you prefer, see Wiki for details.
|
|
|
|
Detailed instructions can be found on [Building OpenRCT2 on Linux](https://github.com/OpenRCT2/OpenRCT2/wiki/Building-OpenRCT2-on-Linux).
|
|
|
|
Note: the `cmake -S . -B build` syntax is available for CMake >= 3.14. For older versions use:
|
|
```
|
|
mkdir build
|
|
cd build
|
|
cmake .. -DCMAKE_INSTALL_PREFIX=. # set your standard cmake options, e.g. build type here - For example, -DCMAKE_BUILD_TYPE=RelWithDebInfo
|
|
cmake --build . --target install
|
|
```

# 4. Contributing
|
|
OpenRCT2 uses the [gitflow workflow](https://www.atlassian.com/git/tutorials/comparing-workflows#gitflow-workflow). If you are implementing a new feature or logic from the original game, please branch off and perform pull requests to ```develop```. If you are fixing a bug for the next release, please branch off and perform pull requests to the correct release branch. ```master``` only contains tagged releases, you should never branch off this.
|
|
|
|
Please read our [contributing guidelines](https://github.com/OpenRCT2/OpenRCT2/blob/develop/CONTRIBUTING.md) for information.
|
|
|
|
## 4.1 Bug fixes
|
|
A list of bugs can be found on the [issue tracker](https://github.com/OpenRCT2/OpenRCT2/issues). Feel free to work on any bug and submit a pull request to the develop branch with the fix. Mentioning that you intend to fix a bug on the issue will prevent other people from trying as well.
|
|
|
|
## 4.2 New features
|
|
Please talk to the OpenRCT2 team first before starting to develop a new feature. We may already have plans for or reasons against something that you'd like to work on. Therefore contacting us will allow us to help you or prevent you from wasting any time. You can talk to us via Discord, see links at the top of this page.
|
|
|
|
## 4.3 Translation
|
|
You can translate the game into other languages by editing the language files in ```data/language``` directory. Please join discussions in the [#localisation channel on Discord](https://discordapp.com/invite/sxnrvX9) and submit pull requests to [OpenRCT2/Localisation](https://github.com/OpenRCT2/Localisation).
|
|
|
|
## 4.4 Graphics
|
|
You can help create new graphics for the game by visiting the [OpenGraphics project](https://github.com/OpenRCT2/OpenGraphics). 3D modellers needed!
|
|
|
|
## 4.5 Audio
|
|
You can help create the music and sound effects for the game. Check out the OpenMusic repository and drop by our [#open-sound-and-music channel on Discord](https://discord.gg/9y8WbcX) to find out more.
|
|
|
|
## 4.6 Scenarios
|
|
We would also like to distribute additional scenarios with the game, when the time comes. For that, we need talented scenario makers! Check out the [OpenScenarios repository](https://github.com/PFCKrutonium/OpenRCT2-OpenScenarios).
