@ -15,6 +15,37 @@ Zeroith, you should be set up to build things because you are a game developer,
First, head on over to the [Discord developers site](https://discordapp.com/developers/applications/me) and make yourself an app. Keep track of `Client ID` -- you'll need it here to pass to the init function.
### Unity Setup
If you're a Unity developer looking to integrate Rich Presence into your game, follow this simple guide to get started towards success:
1. Download the DLLs for any platform that you need from [our releases](https://github.com/discordapp/discord-rpc/releases)
2. In your Unity project, create a `Plugins` folder inside your `Assets` folder if you don't already have one
3. Copy the file `DiscordRpc.cs` from [here](https://github.com/discordapp/discord-rpc/blob/master/examples/button-clicker/Assets/DiscordRpc.cs) into your `Assets` folder. This is basically your header file for the SDK
We've got our `Plugins` folder ready, so let's get platform-specific!
#### Windows
4. Create `x86` and `x86_64` folders inside `Assets/Plugins/`
5. Copy `discord-rpc-win/win64-dynamic/bin/discord-rpc.dll` to `Assets/Plugins/x86_64/`
6. Copy `discord-rpc-win/win32-dynamic/bin/discord-rpc.dll` to `Assets/Plguins/x86/`
7. Click on both DLLs and make sure they are targetting the correct architectures in the Unity editor properties pane
8. Done!
#### MacOS
4. Copy `discord-rpc-osx/osx-dynamic/lib/libdiscord-rpc.dylib` to `Assets/Plugins/`
5. Rename `libdiscord-rpc.dylib` to `libdiscord-rpc.bundle`
6. Done!
#### Linux
4. Copy `discord-rpc-linux/linux-dynamic-lib/libdiscord-rpc.so` to `Assets/Plugins/`
5. Done!
You're ready to roll! For code examples on how to interact with the SDK using the `DiscordRpc.cs` header file, check out [our example](https://github.com/discordapp/discord-rpc/blob/master/examples/button-clicker/Assets/DiscordController.cs)
### From package
Download a release package for your platform(s) -- they have subdirs with various prebuilt options, select the one you need add `/include` to your compile includes, `/lib` to your linker paths, and link with `discord-rpc`. For the dynamically linked builds, you'll need to ship the associated file along with your game.

To make sure it's installed correctly, type `cmake --version` into your flavor of terminal/cmd. If you get a response with a version number, you're good to go!
There's a [CMake](https://cmake.org/download/) file that should be able to generate the lib for you; Sometimes I use it like this:

mkdir build

cmake .. -DCMAKE_INSTALL_PREFIX=<path to install discord-rpc to>

```
There is a wrapper build script `build.py` that runs `cmake` with a few different options.
Usually, I run `build.py` to get things started, then use the generated project files as I work on things. It does depend on `click` library, so do a quick `pip install click` to make sure you have it if you want to run `build.py`.
There are some CMake options you might care about:
| flag | default | does |
|------|---------|------|
| `ENABLE_IO_THREAD` | `ON` | When enabled, we start up a thread to do io processing, if disabled you should call `Discord_UpdateConnection` yourself.
| `USE_STATIC_CRT` | `OFF` | (Windows) Enable to statically link the CRT, avoiding requiring users install the redistributable package. (The prebuilt binaries enable this option)
| [`BUILD_SHARED_LIBS`](https://cmake.org/cmake/help/v3.7/variable/BUILD_SHARED_LIBS.html) | `OFF` | Build library as a DLL
| `WARNINGS_AS_ERRORS` | `OFF` | When enabled, compiles with `-Werror` (on *nix platforms). |

## Sample: send-presence
@ -68,6 +101,33 @@ This is a sample [Unity](https://unity3d.com/) project that wraps a DLL version
This is a sample [Unreal](https://www.unrealengine.com) project that wraps the DLL version of the library with an Unreal plugin, exposes a blueprint class for interacting with it, and uses that to make a very simple UI. Run `python build.py unreal` in the root directory to build the correct library files and place them in their respective folders.
### Using the Unreal Engine plugin with your own project
To use the Rich Presense plugin with Unreal Engine Projects:
1. Download the latest [release](https://github.com/discordapp/discord-rpc/releases) for each operating system you are targeting and the zipped source code
2. In the source code zip, copy the UE plugin—`examples/unrealstatus/Plugins/discordrpc`—to your project's plugin directory
3. At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create an `Include` folder and copy `discord_rpc.h` and `discord_register.h` to it from the zip
4. Follow the steps below for each OS
5. Build your UE4 project
6. Launch the editor, and enable the Discord plugin.
#### Windows
- At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create a `Win64` folder
- Copy `lib/discord-rpc.lib` and `bin/discord-rpc.dll` from `[RELEASE_ZIP]/win64-dynamic` to the `Win64` folder
#### Mac
- At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create a `Mac` folder
- Copy `libdiscord-rpc.dylib` from `[RELEASE_ZIP]/osx-dynamic/lib` to the `Mac` folder
#### Linux
- At `[YOUR_UE_PROJECT]/Plugins/discordrpc/source/ThirdParty/DiscordRpcLibrary/`, create a `Linux` folder
- Inside, create another folder `x86_64-unknown-linux-gnu`
- Copy `libdiscord-rpc.so` from `[RELEASE_ZIP]/linux-dynamic/lib` to `Linux/x86_64-unknown-linux-gnu`
