Himi 嘗試使用了此作者《CSharp – SpritSheet.cs》程式碼段，發現其中有一個演算法估計是作者大意寫錯了。這樣改了就矩形也都支援了。

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:

CSharp – AnimateTiledTexture

A version using coroutines. Slightly faster since it doesn’t update every frame and only sets the texture scale once.
