Himi 尝试使用了此作者《CSharp – SpritSheet.cs》代码段，发现其中有一个算法估计是作者大意写错了。这样改了就矩形也都支持了。

Description
This script animates a texture containing tiles of an animation. You can give it a framerate to determine the speed of the animation and set how many tiles on x, y there are.
Usage
Attach this script to the object that has a material with the tiled texture. To avoid distortion, the proportions of the object must be the same as the proportions of each tile (eg 1:2 for the sheet below).
Here is an example of how to lay out a texture for it (Thanks to BigBrainz for providing it):
(Leo Nogueira) Adding a simple image with multiple rows for testing purposes and a modified version of the C# Script:
