unity控制材质颜色或者更换材质
控制材质颜色或者更换材质
（标注部分为主要内容）
主要知识点：
声明一个数组：
public Button[] btns;
public string colors;
获得Resources目录下某个文件夹下的全部材质
Material[] matArr = Resources.LoadAll<Meterial>("Materials/colors");
字典对象的使用
Dictionary<string,Material> matdic = new Dictionary<string,Material>();
Material redmat = matArr[0];
matdic.add("red",redMat);
1.如何使用for循环
2.给按钮添加鼠标事件onClick.AddListener
3.获取物体上面的组件GetComponent方法
4.获取物体的SkinnedmeshRenderer渲染器，修改它的material属性变换材质，或者修改material.color属性改变颜色

//声名一个数组

//使用 Resources.LoadAll加载资源目录下的某个文件夹下的所有资源

Resources.LoadAll<Material>("Materials/colors");
//如何使用for循环for (int i=0;i<4;i++)
for (int i = 0; i < 4; i++) {
Debug.Log(i);
//一对对把材质存到字典里
matdic.Add(colors[i], matArr[i]);
}
//给按钮添加鼠标事件onClick.AddListener
// 没有名字的方法 ，匿名方法
btns[0].onClick.AddListener(delegate()
{ ChangeColorByMat("blue"); });
btns[1].onClick.AddListener(delegate() { ChangeColorByMat("green"); });
btns[2].onClick.AddListener(delegate() { ChangeColorByMat("red"); });

//btns[1].onClick.AddListener(delegate() { ChangeColorByHex("04FBB4FF");)
