上面的方法不通过,texture 没有 GetPixels

抱歉,我的回答有误。Texture确实没有GetPixels方法。如果要将Texture转换为Texture2D可以使用RenderTexture来实现。具体步骤如下:
1. 创建一个RenderTexture,将待转换的Texture赋值给RenderTexture的color属性:
```csharp
RenderTexture renderTexture = new RenderTexture(texture.width, texture.height, 0);
Graphics.Blit(texture, renderTexture);
```
2. 创建一个Texture2D,将RenderTexture的像素数据读取到Texture2D中:
```csharp
Texture2D texture2D = new Texture2D(renderTexture.width, renderTexture.height);
RenderTexture.active = renderTexture;
texture2D.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);
RenderTexture.active = null;
```
3. 将读取到的像素数据应用到Texture2D中:
```csharp
texture2D.Apply();
```
完整代码如下:
```csharp
Texture texture = ...; //待转换的Texture
RenderTexture renderTexture = new RenderTexture(texture.width, texture.height, 0);
Graphics.Blit(texture, renderTexture);
Texture2D texture2D = new Texture2D(renderTexture.width, renderTexture.height);
RenderTexture.active = renderTexture;
texture2D.ReadPixels(new Rect(0, 0, renderTexture.width, renderTexture.height), 0, 0);
RenderTexture.active = null;
texture2D.Apply();
```
需要注意的是,使用RenderTexture会对性能产生一定的影响,因此需要根据实际情况进行权衡。
