RANDOM PACMAN 任务是为 5 个对象(pac man 和 4 个随机移动的幽灵)设置动画,如果 pac man 与一个幽灵碰撞,他会从它身上弹开,幽灵会相互穿过,并且在被 pac man 击中时不受影响。当鼠标单击模式更改,如果 pac man 发生碰撞并且 pac man 不受影响,则幽灵会反弹,如果再次单击鼠标,它将恢复到原始模式。函数 ghost_collision 和 mode_swich 处理这个问题,最后我有一个 if 语句鼠标点击。BUG1我不知道为什么当精灵碰撞时它们有时会变得不动(在两种模式下)。我是否可以用列表和 for 循环替换一些重复的 if 语句?如果是这样怎么办?我尝试制作所有 ghost_boundary 变量的列表,然后使用
For sprite in sprite_list():
sprite.left < 0 or sprite.right > WIDTH:
sprite_velocity[1] = -1 * sprite_velocity[1]
那失败了。
