Unity3D如何实现 Sprite和Texture2D互转

Unity3D如何实现 Sprite和Texture2D互转

1：克隆Texture2D //originTex为克隆对象 Texture2D newTex; newTex = new Texture2D(originTex.width, originTex.height); Color[] colors = originTex.GetPixels(0, 0, originTex.width, originTex.height); newTex.SetPixels(colors); newTex.Apply();//必须apply才生效

2：Sprite转Texture2D//sprite为图集中的某个子Sprite对象        var targetTex = new Texture2D((int)sprite.rect.width, (int)sprite.rect.height);        var pixels = sprite.texture.GetPixels(            (int)sprite.textureRect.x,            (int)sprite.textureRect.y,            (int)sprite.textureRect.width,            (int)sprite.textureRect.height);        targetTex.SetPixels(pixels);        targetTex.Apply();

3： Texture2D转Sprite//t2d为待转换的Texture2D对象Sprite s= Sprite.Create(t2d, new Rect(0, 0, t2d.width, t2d.height), Vector2.zero);

楼上的回答太专业了吧

元素是个好家园，加油啊
