public class color : MonoBehaviour
{public Color oldcolor;// Start is called before the first frame updatevoid Start(){oldcolor = GetComponent<Renderer>().material.color;  //获取颜色}void OnMouseOver(){GetComponent<Renderer>().material.color = Color.red; //变成红色}void OnMouseExit(){GetComponent<Renderer>().material.color = oldcolor;  //变回原来的颜色}

鼠标不在物体上        鼠标放在物体上
