我该如何使播放器不从平台侧入迷

问题描述

我已经开始玩这个游戏了，我一直在尝试制作它，所以当玩家触摸我的方块的侧面时，它不会从里面消失并真正停止，我希望它像一个完全正常的方块一样工作，让您停止当您触摸侧面时。

如您所见，每次我碰到砌块的侧面时，它都会穿透它，但是我不希望它融化，我想要它实际碰到侧面，我知道如何使其碰到砖块。平台的顶部，但我不知道如何使其接触平台的侧面和底部。我已经尝试了下面显示的代码，但是没有用。

我尝试过的代码

   if event.type == pygame.K_s:
        if keys == pygame.K_a:
             x_change = -7
    if keys == pygame.K_d:
         x_change = 7

    if event.type == pygame.KEYUP:
        if keys == pygame.K_a or keys == pygame.K_d:
             x_change = 0

    x += x_change
    if x > 500 - playerman.width or x < 0:
            x = old_x

解决方法

当我制作平台游戏时，我会检查每一帧，看玩家是否正在与障碍物碰撞。伪代码：

if player.movement_vel.x>0 and player.collide_obst():
    player.right=player.collide_obst().rect.left

这有点抽象。我只是假设player.collide_obst（）函数返回与他碰撞的一个障碍。当然，您必须： -使它也可以与玩家左右移动来配合使用，我建议您这样做，因此collide_obst（）函数返回一个您在其中循环的列表。学习这样的东西的好来源是： https://www.youtube.com/watch?v=Qdeb1iinNtk他在视频中以相同的方式报道了碰撞。希望我能帮到您，拉斯
