使用unity编程 编出一个简单的按钮 如果鼠标停在按钮上改变造型放音效 离开就变回原来的造型 摁下按钮触发事件

ng UnityEngine;
using System.Collections;

public class Button : MonoBehaviour {
    public bool isPressed = false;
    public bool isHovered = false;
    public bool isClicked = false;
    public bool isDisabled = false;
    public bool isActive = false;
    public bool isSelected = false;
    public bool isFocused = false;
    public bool isHoveredOver = false;
