D3D Plugin for CryEngine

Purpose of this plugin is to provide access to the Direct3D device and to the renderthread, so that custom Direct3D rendering can be achieved.

Installation / Integration

Use the installer or extract the files to your CryEngine SDK Folder so that the Code and BinXX/Plugins directory match up.

The plugin manager will automatically load up the plugin when the game/editor is restarted or if you directly load it.

Its recommended that you install the DirectX SDK

C++ Integration

Follow these steps to integrate the D3D Plugin into your Plugin or GameDLL.

Repository Setup

Clone the repository to your local machine to your Code directory e.g. C:\cryengine3_3.4.0\Code.
Use a github UI version like Github for Windows
or if you already have git installed

    git clone https://github.com/hendrikp/Plugin_SDK.git

Compiler Settings

Open the solution CryEngine_GameCodeOnly.sln
- or Open the solution of your plugin
Open CryGame properties
- or Open the properties of your plugin
Set the Dropdowns to All Configurations, All Platforms
Add to C/C++ -> General -> Additional Include Directories

$(SolutionDir)..\Plugin_D3D\inc

Apply those properties and close the dialog

Building / Compiling

Use the supplied seperate solution to compile this project.
Or use the supplied batch tools\build.bat to build this project only.
Or use the supplied batch Plugin_SDK\build_all.bat to build all plugins in the Code directory and the GameDll.
Or add the project file to your CryGame solution and the plugin manager as dependency for each plugin.

Samples

Getting the Direct3D Device

The same method applies to DirectX 11 (exchange interface and header names)

Open the file where you want to access DirectX
Add behind the existing includes the following:

	#include <IPluginManager.h>
    #include <IPluginD3D.h>
    #include <d3d9.h>

To get the device use the following in the Plugin:

    IDirect3DDevice9* pDevice = gD3DSystem ? static_cast<IDirect3DDevice9*>(gD3DSystem->GetDevice()) : NULL;

or in the GameDLL the following :

	IPluginD3D* pPlugin = PluginManager::safeGetPluginConcreteInterface<D3DPlugin::IPluginD3D*>( "D3D" );
    IDirect3DDevice9* pDevice = pPlugin ? static_cast<IDirect3DDevice9*>(pPlugin->GetDevice()) : NULL;

I recommend saving the device pointer somewhere for reuse. (it won't change anymore during this run)

Realize custom rendering

To use the device at the correct moment you have to create a Listener class. Use this sample as your base by simply adding it to your project and creating an instance. This event listener runs in the renderthread.

This sample will make your rendering window green, but you are free to do something more meaningfull ;)

Sample File DX9 (include into a cpp file of your choice or paste it there)
