# Discord RPC
|
|
|
|
This is a lib and quick demos that implement the very minimal subset to show current status, and
|
|
have callbacks for where a more complete game would do more things. You can use the lib directly
|
|
if you like, or use it as a guide to writing your own if it doesn't suit your game as is.
|
|
|
|
PRs/feedback welcome if you have an improvement everyone might want, or can describe how this
|
|
doesn't meet your needs.
|
|
|
|
## Documentation
|
|
|
|
The most up to date documentation for Rich Presence can always be found in our [developer site](https://discordapp.com/developers/docs/topics/rich-presence)!
|
|
|
|
## Usage
|
|
|
|
Zeroith, you should be set up to build things because you are a game developer, right?
|
|
|
|
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.
|
|
|
|
### From package
|
|
|
|
Download a release package, extract it, add `/include` to your compile includes, `/lib` to your
|
|
linker paths, and link with `discord-rpc`.
|
|
|
|
### From repo
|
|
|
|
There's a [CMake](https://cmake.org/download/) file that should be able to generate the lib for
|
|
you; I use it like this:
|
|
```sh
|
|
cd <path to discord-rpc>
|
|
mkdir build
|
|
cd build
|
|
cmake .. -DCMAKE_INSTALL_PREFIX=<path to install discord-rpc to>
|
|
cmake --build . --config Release --target install
|
|
```
|
|
Sometimes I use the generated project files. There are a couple of 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.
|
|
| `BUILD_DYNAMIC_LIB` | `OFF` | Build library as a DLL
|
|
|
|
## Sample: send-presence
|
|
|
|
This is a text adventure "game" that inits/deinits the connection to Discord, and sends a presence
|
|
update on each command.
|
|
|
|
## Sample: button-clicker
|
|
|
|
This is a sample [Unity](https://unity3d.com/) project that wraps a DLL version of the library, and
|
|
sends presence updates when you click on a button.
|
|
|
|
## Sample: unrealstatus
|
|
|
|
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.
