1、计算机实习报告学院:班级:学号:姓名:1、题目要求：作一个两辆赛车比赛的游戏，要求可以用A, S, D, W和小键盘的上下左右键控制小汽车的运行方向进行比赛。设计方案：所用软件为 Adobe Flash CS5设置控制键，通过按键对小车进行控制，在控制的同时判断小车的位置使其行驶在跑道上， 当有一辆赛车跑完三圈时，比赛结束，并输出比赛结果。流程图：设计过程：1.首先要让赛车能够动起来。让赛车运动不是最难的一部分首先在defs的图层里打开actions窗口，设定好赛车的加速度，减速度，最大速度，以及圈数等基本常量值。Flash中使用的的是经典的直角坐标系，所以我们在计算赛车实际的速度时要把速度分

2、解到X轴和Y轴上，得到X分量和Y分量（如下图）。计算上述分量就要知道角度， Flash中对角度和弧度要进行转化：angle_radians = angle_degrees * （ PI/180）。再加上函数，就可以让我们的车动起来。这里我用了两个类似的函数来分别控制两辆赛车，他们 只有控制方向的按键不同的。2 还需要处理碰撞的问题。碰撞时整个赛车游戏中十分重要的一部分，因为我们必须把赛车限制在跑道内，并且让玩家可以在最快的时间内完成比赛。在车的四边分别设置一个点， 用来检测它是否碰到了不可进入的区域。如果碰到了赛道，那么赛车的速度将会降低，并且赛车的方向会得到纠正。IhlFD! 、-+aX A
