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。开始流程图：方向键控制对两小车是否碰到跑道进行判断小车停止Y N判断比赛是否完成NY显示比赛的输赢结束设计过程：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。3处理圈数和计时的问题。设置了两个函数来分别计算总的比赛时间setTimes和单圈最好成绩setBestLap。当赛车连续经过两次检查点checkpoint时则完成一圈，当完成三圈时游戏结束，显示游戏结果。源代码：Defs:car1.code = player;car2.code = playertotalLaps = 3;acceleration = 0.4;speedDecay = 0.96;rotationStep = 10;maxSpeed = 10;backSpeed = 1;currentCheckpoint1 = 1;currentCheckpoint2 = 1;currentLap1 = 0;currentLap2 = 0;checkpoints = 2;currentLapTXT = 1/3;Actions：function step(who) if (_rootcar+who.code = player) if (thisspeed+who0.3) thisspeed+who *= _root.speedDecay;
