This enum describes what should be done on the render target when it is activated (loaded).
When the GPU starts rendering into a render target, this setting specifies the action that should be performed on the existing contents of the surface. Tile-based GPUs may get performance advantage if the load action is Clear or DontCare. The user should avoid using RenderBufferLoadAction.Load whenever possible.
すべてのプラットフォームが load/store アクションを行うというわけではない点に注意してください。したがって、この設定はランタイム時無視されることがあります。一般的に、モバイル志向のグラフィックス API (OpenGL ES、Metal) は、これらの設定を利用します。
| Load | When this RenderBuffer is activated, preserve the existing contents of it. This setting is expensive on tile-based GPUs and should be avoided whenever possible. |
| Clear | Upon activating the render buffer, clear its contents. Currently only works together with the RenderPass API. |
| DontCare | When this RenderBuffer is activated, the GPU is instructed not to care about the existing contents of that RenderBuffer. On tile-based GPUs this means that the RenderBuffer contents do not need to be loaded into the tile memory, providing a performance boost. |
