cocos2d-android——Action（4）

1、MainActivity

package com.njupt.ccaction04;

import org.cocos2d.layers.CCScene;
import org.cocos2d.nodes.CCDirector;
import org.cocos2d.opengl.CCGLSurfaceView;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

	//cocos2d引擎会把图形会知道在该view对象上
	private CCGLSurfaceView view = null;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		view = new CCGLSurfaceView(this);
		setContentView(view);
		
		
		CCDirector director = CCDirector.sharedDirector();//得到CCDirector对象
		/**
		 * 设置游戏程序的相关属性
		 */
		director.attachInView(view);//设置当前游戏程序中所使用的view对象
		director.setDisplayFPS(true);//设置游戏程序是否显示FPS值
		director.setAnimationInterval(1.0f/60);//设置游戏渲染一帧所需要的时间
		
		//生成一个游戏场景对象
		CCScene scene = CCScene.node();
	
		//生成布景层对象
		GameLayer gameLayer = new GameLayer();
		
		//将布景层对象添加至游戏场景中
		scene.addChild(gameLayer);
		
		//运行游戏场景
		director.runWithScene(scene);
		
	}

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.main, menu);
		return true;
	}

		 */

//		sprite.runAction(tintBy);
		
		/**

		 * 
		 * CCRepeatForever.action(seq);
