DllNotFoundException: discord-rpc

[holmraven]

I'm complete newb, and I don't know where to get the dll. Can someone help?

[holmraven]

I'm using Unity

[msciotti]

There's a couple things you can do. You can either get it from our releases, or you can run python build.py unity in the root directory of the repository to compile the latest and greatest from the source code.

[holmraven]

There's .h and .lib files in releases, what I am supposed to do with them?

[holmraven]

Unity requires dll file from me

[msciotti]

The releases also include .dll files in win64-dynamic/bin/.

In your Assets folder in Unity, you'll need a Plugins folder. In that folder, you'll need a x86 folder and a x86_64 folder for 32 and 64 bit versions of your game. You should place the 32 and 64 bit dlls inside those two respective folders.

The .h file is a header file, which you don't need for unity. What you will need is the DiscordRpc.cs file from the unity example, which is how your Unity game will talk to the dll.

What I recommend is doing this:

1. Clone the repo
2. Run python build.py unity from the root directory
3. Open discord-rpc/examples/button-clicker example in Unity
4. See how the files are laid out, and look at DiscordController.cs for how to talk to the SDK.
5. Copy that structure in your own game.

[msciotti]

You'll need to install CMake. https://cmake.org/download/

Or, you can download the files from releases, and put them in those folders I mentioned.

[holmraven]

I have CMake, as I said the files from releases don't work, because I don't think c++ and c# code can contact directly. I tried to manipulate with them but unity requires a dll from me

...yes, the files from releases work. I assume you are on windows. Go to releases, and download discord-rpc-win.zip. Inside of that is this folder structure.

Inside win64-dynamic and win32-dynamic are bin folders. Inside those bin folders are discord-rpc.dll files for 32 and 64 bit windows. Those are the files to put in the Assets\Plugins folder inside Unity. The DiscordRpc.cs file from discord-rpc\examples\button-clicker\Assets should be placed inside the Assets folder of your Unity project. It's a header file to talk to the dll.

[holmraven]

Oh maaan, thank you, I only looked into include and lib folders, because I opened bin folder in static version first, I thought it will be the same in dynamic

[holmraven]

Haha, thank you now I figured it out!
