继承了CCLayer的图层类的基本写法：

public class GameLayer extends CCLayer {
    // 声明一个精灵对象
    CCSprite player;

    public GameLayer() {
        // 初始化精灵对象
        player = CCSprite.sprite("tank_a.png");

        // 设置精灵位置的两种方法

        /*
         * //方法一: 设置精灵对象的位置 player.setPosition(100, 100);
         */

        // 方法二:设置对象 常用于表示坐标，或者是表示向量
        CGPoint point = CGPoint.ccp(100, 100);
        player.setPosition(point);
        
        this.addChild(player);
        
        //生成一个JumpTo,该对象表示一个跳跃的动作
        CGPoint target = CGPoint.ccp(400, 100);
        CCJumpTo jumpTo = CCJumpTo.action(3,target,200,10);

        player.runAction(jumpTo);
