Question

JavaScript => public function MarkRestoreExpected(): void;
C# => public void MarkRestoreExpected();

Description 描述

Indicate that there's a RenderTexture restore operation expected.

表明渲染纹理恢复预期操作。

When in mobile graphics emulation mode, Unity issues warnings when a RenderTexture “restore” operation is performed. Restore happens when rendering into a texture, without clearing or discarding (DiscardContents) it first. This is a costly operation on many mobile GPUs and multi-GPU systems and best should be avoided.

当在移动图形仿真模式，当Unity执行渲染还原操作时发出警告。当渲染纹理没有清除或者首先丢弃它(DiscardContents)时还原发生。在很多移动 Gpu 和多 GPU 系统上，这是一个高负荷的操作，最好避免。

However, if your rendering effect absolutely needs a RenderTexture restore, you can call this function to indicate that yes, a restore is expected, and Unity will not issue a warning here.

但是，如果你的渲染效果必须要渲染纹理还原，你可以调用该函数表明那是必须的，还原时预期的，并且在这里Unity将不会发出警告。
