unity 实时重复纹理

在编辑器模式下

update里加上gameObject.GetComponent<MeshRenderer>().sharedMaterial.mainTextureScale = new Vector2(transform.localScale.x,transform.localScale.y);

就可以了，但是有缺点就是复制该物体时会产生新的材质从而有泄露，报错

Instantiating material due to calling renderer.material during edit mode. This will leak materials into the scene. You most likely want to use renderer.sharedMaterial instead.

不过不是大问题，因为只存在场景内，场景关闭或者切换的时候会自动释放
