# Discord RPC
|
||||
|
||||
This is a library for interfacing your game with a locally running Discord desktop client. It's known to work on Windows, macOS, and Linux. 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.
|
||||
|
||||
Included here are some 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 (joining, spectating, etc).
|
||||
|
||||
## Documentation
|
||||
|
||||
The most up to date documentation for Rich Presence can always be found on our [developer site](https://discordapp.com/developers/docs/rich-presence/how-to)! If you're interested in rolling your own native implementation of Rich Presence via IPC sockets instead of using our SDK—hey, you've got free time, right?—check out the ["Hard Mode" documentation](https://github.com/discordapp/discord-rpc/blob/master/documentation/hard-mode.md).
|
||||
|
||||
## Basic 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 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.
|
||||
|
||||
### From repo
|
||||
|
||||
First-eth, you'll want `CMake`. There's a few different ways to install it on your system, and you should refer to [their website](https://cmake.org/install/). Many package managers provide ways of installing CMake as well.
|
||||
|
||||
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:
|
||||
```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
|
||||
```
|
||||
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). |
|
||||
|
||||
## Continuous Builds
|
||||
|
||||
Why do we have three of these? Three times the fun!
|
||||
|
||||
| CI | badge |
|
||||
|----|-------|
|
||||
| TravisCI | [](https://travis-ci.org/discordapp/discord-rpc)
|
||||
| AppVeyor | [](https://ci.appveyor.com/project/crmarsh/discord-rpc)
|
||||
| Buildkite (internal) | [](https://buildkite.com/discord/discord-rpc)
|
||||
|
||||
## 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. Run `python build.py unity` in the root directory to build the correct library files and place them in their respective folders.
|
||||
|
||||
## 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. Run `python build.py unreal` in the root directory to build the correct library files and place them in their respective folders.
|
||||
|
||||
## Wrappers and Implementations
|
||||
|
||||
Below is a table of unofficial, community-developed wrappers for and implementations of Rich Presence in various languages. If you would like to have yours added, please make a pull request adding your repository to the table. The repository should include:
|
||||
|
||||
- The code
|
||||
- A brief ReadMe of how to use it
|
||||
- A working example

\brief Concept for allocating, resizing and freeing memory block.

Note that Malloc() and Realloc() are non-static but Free() is static.

So if an allocator need to support Free(), it needs to put its pointer in

the header of memory block.

// \param size of the memory block in bytes.
|
||||
// \returns pointer to the memory block.
|
||||
void* Malloc(size_t size);
|
||||
|
||||
// Resize a memory block.
|
||||
// \param originalPtr The pointer to current memory block. Null pointer is permitted.
|
||||
// \param originalSize The current size in bytes. (Design issue: since some allocator may not book-keep this, explicitly pass to it can save memory.)
|
||||
// \param newSize the new size in bytes.
