Unity的button脚本及MaterialPropertyBlock使用、C#数组转list

MaterialPropertyBlock使用

优点：设置material里shader的属性更直接，还能遍历整个场景的shader，设置其属性。

代码

MaterialPropertyBlock props;
private List<Renderer> myRenderer=new List<Renderer>();

props = new MaterialPropertyBlock();
Renderer[] rd =GameObject.FindObjectsOfType<Renderer>();
myRenderer =new List<Renderer>(rd);
props.SetFloat("_ColliderForce", 0);
foreach(Renderer render in myRenderer)
render.SetPropertyBlock(props);
上面的脚本会把他所在场景所有其他物体属性都修改
当然，也可以每个物体挂一个脚本一个shader，只控制该物体本身的。

props.SetFloat("_ColliderForce", 0);
foreach(Renderer render in myRenderer)
render.SetPropertyBlock(props);

note：同一个物体上挂两个材质球也是好使的，两个材质球的属性都会被修改

数组转list：new List(数组变量)

Gui值用法

button、label的使用

参考：http://blog.csdn.net/zuoyamin/article/details/17261361

using UnityEngine;
using System.Collections;

public class Button1 : MonoBehaviour
{

public Texture img;
private Texture img0;
private string info;//显示的信息/
private int frameTime;//记录按下的时间/
MaterialPropertyBlock props;
private Renderer myRenderer;

void Start()
{
//初始化/
info = "请您点击按钮";
frameTime = 0;
props = new MaterialPropertyBlock();
myRenderer = GetComponent<Renderer>();
}

void OnGUI()
{
//标签/
//设置标签字体
GUIStyle style = GUI.skin.GetStyle("label");
style.fontSize = 40;
GUI.Label(new Rect(50, 10, 200, 20), info);
//普通按钮，点击后显示Hello World
if (GUI.Button(new Rect(150, 100, 200, 20), "lyg设为0"))
{
//info = "Hello World";
props.SetFloat("_ColliderForce", 0);
myRenderer.SetPropertyBlock(props);
info = "您点击了图片按钮,shewei0";
Debug.Log("设置为0");
}
//标签/
//GUI.Label(new Rect(280, 10, 200, 200), img0);
//图片按钮,点击后显示图片/
//if (GUI.Button(new Rect(280, 250, 200, 200), img))
//{
//    img0 = img;

//    props.SetFloat("_ColliderForce", 1);
//    myRenderer.SetPropertyBlock(props);
//    info = "您点击了图片按钮,shewei1";
//}
//标签/
//GUI.Label(new Rect(500, 10, 200, 20), "持续按下的时间：" + frameTime);
//连续按钮，点击后显示按下的时间/
if (GUI.Button(new Rect(380, 100, 200, 20), "lyg设为1"))
{
//frameTime++;
props.SetFloat("_ColliderForce", 1);
myRenderer.SetPropertyBlock(props);
//info = "您点击了图片按钮,shewei1";
info = "您按下了连续按钮,shewei0";
Debug.Log("设置为1");

}
//每当鼠标按下时将frameTime重置，一遍进行下次记录/
if (Input.GetMouseButtonDown(0))
{
frameTime = 0;
}
}
}

gui之button、label字体大小、颜色修改

参考：https://docs.unity3d.com/Manual/gui-Customization.html

颜色修改

GUI.color = Color.red;

label字体

GUIStyle style = GUI.skin.GetStyle("label");
style.fontSize = 40;

GUI.Label(new Rect(widthOffset + 100, 200, 600, 300),  "now " + (Camera.main.allowMSAA ? "opened ................" : "not opened") + " MSAA");
GUI.Label(new Rect(widthOffset + 100, 300, 600, 300), "now " + (Camera.main.allowHDR ? "opened ................" : "not opened") + " HDR");

其他控件的字体

//toggle字体
GUIStyle style1 = GUI.skin.GetStyle("Toggle");
style1.fontSize = 40;

m_toggle0 = GUI.Toggle(new Rect(widthOffset + 200, 400, 400, 200), Camera.main.allowMSAA, "Toggle MSAA         !");
m_toggle1 = GUI.Toggle(new Rect(widthOffset + 250, 600, 400, 200), Camera.main.allowHDR, "Toggle HDR!");

//button字体
GUIStyle style1 = GUI.skin.GetStyle("Button");
style1.fontSize = 40;

toggle的使用

//成员变量
private bool m_toggle0 = false;
private bool m_toggle1 = false;

//OnGUI里
m_toggle0 = GUI.Toggle(new Rect(widthOffset + 200, 400, 400, 100), Camera.main.allowMSAA, "Toggle MSAA         !");
m_toggle1 = GUI.Toggle(new Rect(widthOffset + 250, 600, 400, 100), Camera.main.allowHDR, "Toggle HDR!");
if (m_toggle0)
{
Camera.main.allowMSAA = true;
QualitySettings.antiAliasing = 2;
}
else
{
Camera.main.allowMSAA = false;
}

if (m_toggle1)
{
Camera.main.allowHDR = true;
}
else
{
Camera.main.allowHDR = false;
}
