求助一下pygame的碰撞检测问题
自己写的一个打砖块游戏 碰撞检测部分如下 我的球只有遇到边框会发生反弹 在需要到mask碰撞检测的地方就会直接穿过砖块跟板子是怎么回事呢{:5_96:} file:///C:/Users/Folly/Desktop/L%7BJKU(GS)5_T55VZUH1E$%7B6.png #检测球的碰撞for each in brick_list:

您这是百度的代码答案啊 我想要知道的是能不能偷懒直接用碰撞检测函数来完成{:10_261:} Folly 发表于 2020-5-3 22:04

我是看到小甲鱼视频里面可以直接用一个内置的碰撞检测函数来判断是否发生碰撞 而不是像这样用数学方法重新算一遍 Folly 发表于 2020-5-3 22:07
