鼠标悬停在游戏对象上方时，不会改变游戏对象的材质

using UnityEngine;

public class MouseHover : MonoBehaviour
{
    private Material originalMaterial;
    private Renderer renderer;

    private void Start()
    {
        renderer = GetComponent<Renderer>();
        originalMaterial = renderer.material;
    }

    private void OnMouseEnter()
    {
        // 鼠标悬停时不改变材质
    }

    private void OnMouseExit()
    {
        renderer.material = originalMaterial;
    }
}
