Unity添加GIF动画
国外网站上看到的一篇帖子

它使用“图像”和“图形”类的系统。图的命名空间,所以需要“system.Drawing.dll“要导入的文件/添加到项目中。
使用前准备:
1)复制”"System.Drawing.dll" file in the "C:\Program Files (x86)\Unity\Editor\Data\Mono\lib\mono\2.0"文件到"Assets" 文件夹下面。
2)创建一个新的脚本命名为“animatedgifdrawer”,与下面的内容。
3)将这个脚本场景中的任何对象。
4)更改脚本”loadinggifpath”字段,你的GIF文件的路径。(这可以从根项目文件夹是相对的也可以是绝对的。
下面给出C#代码:
using System.Collections.Generic; using System.Drawing; using System.Drawing.Imaging; using UnityEngine; public class AnimatedGifDrawer : MonoBehaviour { public string loadingGifPath; public float speed = 1; public Vector2 drawPosition; List<Texture2D> gifFrames = new List<Texture2D>(); void Awake() { var gifImage = Image.FromFile(loadingGifPath); var dimension = new FrameDimension(gifImage.FrameDimensionsList[0]); int frameCount = gifImage.GetFrameCount(dimension); for (int i = 0; i < frameCount; i++) { gifImage.SelectActiveFrame(dimension, i); var frame = new Bitmap(gifImage.Width, gifImage.Height); System.Drawing.Graphics.FromImage(frame).DrawImage(gifImage, Point.Empty); var frameTexture = new Texture2D(frame.Width, frame.Height); for (int x = 0; x < frame.Width; x++) for (int y = 0; y < frame.Height; y++) { System.Drawing.Color sourceColor = frame.GetPixel(x, y); frameTexture.SetPixel(frame.Width - 1 - x, y, new Color32(sourceColor.R, sourceColor.G, sourceColor.B, sourceColor.A)); // for some reason, x is flipped } frameTexture.Apply(); gifFrames.Add(frameTexture); } } void OnGUI() { GUI.DrawTexture(new Rect(drawPosition.x, drawPosition.y, gifFrames[0].width, gifFrames[0].height), gifFrames[(int)(Time.frameCount * speed) % gifFrames.Count]); } }
