【图】高级游戏制作：Flash制作物体弹跳电脑游戏

　　Flash制作物体弹跳电脑游戏，这是一种背景不动的一个物体可以弹跳，可以左右走动的小游戏。比较基础的游戏。

看不到动画效果的朋友请去这里观看：http://bbs.jcwcn.com/thread-99274-1-1.html

　　启动Flash，首先修改文档属性。

　　首先制作两个电影剪辑一个是背景，绘制一个矩形小块来当背景。加入AS为：stop()，让它开始就停止。

　　另外一个是运动的物体，给大家截图如下。

回到主场景，我们用Actionscript来实现其它效果。在主场景的第一帧直接加入下面代码： xspeed = 0;
yspeed = 0;
max_yspeed = 16;
gravity = 1;
walk_speed = 4;
level = new Array();
_root.createEmptyMovieClip("lev", _root.getNextHighestDepth());
level[0] = new Array(1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1);
level[1] = new Array(1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1);
