本文介绍如何在Unity中使用UICenterOnChild组件实现网格内对象的居中显示及缩放效果，并通过按钮控制切换不同的显示项。

首先给UIGrid添加UICenterOnChild脚本

在两个锁的点击事件中获取到UICenterOnChild CenterOn()方法进行传参这样物体就能居中显示了

using UnityEngine;
using System.Collections;

public class OnCenterByOne : MonoBehaviour {

	// Use this for initialization
	public  UICenterOnChild muicenterOnchild;
	public  GameObject mgrid;
	public GameObject nextBtn;
	public GameObject upBtn;

	int number=2;
	void Start () {
		muicenterOnchild.CenterOn (mgrid.transform.GetChild (number).transform);

		UIEventListener.Get (nextBtn.gameObject).onClick += NetxBtn;
		UIEventListener.Get (upBtn.gameObject).onClick += UpBtn;
	}
	void NetxBtn(GameObject go){
    //我那个是用Toggle 来判断当前在中间的是那个，你这个可以用一个int值来控制
		if (number==3) {
			nextBtn.gameObject.SetActive (false);
			upBtn.gameObject.SetActive (true);
			muicenterOnchild.CenterOn (mgrid.transform.GetChild (number+1).transform);
			mgrid.transform.GetChild (number + 1).transform.localScale = new Vector3 (2, 2,2 );
			mgrid.transform.GetChild (number).transform.localScale = new Vector3 (1, 1, 1);
			number += 1;
		}else {
			muicenterOnchild.CenterOn (mgrid.transform.GetChild (number+1).transform);
			mgrid.transform.GetChild (number + 1).transform.localScale = new Vector3 (2, 2, 2);
			mgrid.transform.GetChild (number).transform.localScale = new Vector3 (1, 1, 1);
			upBtn.gameObject.SetActive (true);
			nextBtn.gameObject.SetActive (true);
			number += 1;
		}

	}
	void UpBtn(GameObject go){
		if (number==1) {
			upBtn.gameObject.SetActive (false);
			muicenterOnchild.CenterOn (mgrid.transform.GetChild (number-1).transform);
			mgrid.transform.GetChild (number - 1).transform.localScale = new Vector3 (2, 2, 2);
			mgrid.transform.GetChild (number).transform.localScale = new Vector3 (1, 1, 1);
			number -= 1;
		}else {
			muicenterOnchild.CenterOn (mgrid.transform.GetChild (number-1).transform);
			mgrid.transform.GetChild (number - 1).transform.localScale = new Vector3 (2, 2, 2);
			mgrid.transform.GetChild (number).transform.localScale = new Vector3 (1, 1, 1);
			upBtn.gameObject.SetActive (true);
			nextBtn.gameObject.SetActive (true);
			number -= 1;
		}
	}
}
