JavaScript => public function DiscardContents(): void;
JavaScript => public function DiscardContents(discardColor: bool, discardDepth: bool): void;
C# => public void DiscardContents();
C# => public void DiscardContents(bool discardColor, bool discardDepth);

Parameters 参数

discardColor	Should the colour buffer be discarded?
discardDepth	Should the depth buffer be discarded?

Description 描述

Discards the contents of the RenderTexture.

渲染纹理丢失的内容。

On some platforms, it can be good for performance if you indicate when the current contents of a RenderTexture aren't needed any more. This can save copying it from one kind of memory to another when the texture is reused. Xbox 360 and many mobile GPUs benefit from this.

在某些平台上，如果你表明当前渲染纹理的内容一点也不需要时它有助于提高性能。当纹理被重复利用时该函数可以从一个内存拷贝到另一个内存中保存。 该函数有益于Xbox 360和许多手机GPUs。

Both the colour buffer and depth buffer are discarded by default but either can be selected individually using the optional boolean parameters.

颜色缓存和深度缓存两个是默认丢失的但是也可以使用选择布尔参数单独选择。
