Question

JavaScript => public function GetPixels32(x: int, y: int, blockWidth: int, blockHeight: int): Color32[];
C# => public Color32[] GetPixels32(int x, int y, int blockWidth, int blockHeight);

Parameters 参数

x	X-coord of the top-left corner of the rectangle to grab.
y	Y-coord of the top-left corner of the rectangle to grab.
blockWidth	Width of rectangle to grab.
blockHeight	Height of the rectangle to grab. Get the pixel values from a rectangular area of a ProceduralTexture into an array. The block is specified by its x,y offset in the texture and by its width and height. The block is “flattened” into the array by scanning the pixel values across rows one by one.

Description 描述

Grab pixel values from a ProceduralTexture.

从程序纹理中攫取像素值。

This only works for ProceduralMaterial instances that have been marked as “Readable” and whose texture format is set to RAW.

这仅作用于程序材质实例，该实例已经被标记为“可读”和纹理格式设置为RAW。

The correct sequence to use GetPixels32() is:

使用GetPixels32()的正确顺序是：

- Set the ProceduralMaterial “Readable” flag using ProceduralMaterial.isReadable

使用ProceduralMaterial.isReadable，设置程序材质“可读”标志

- Rebuild the ProceduralMaterial's textures using ProceduralMaterial.RebuildTexturesImmediately

使用ProceduralMaterial.RebuildTexturesImmediately，重建程序材质的纹理

- Call GetPixels32().

调用GetPixels32()。
