Question

我正在尝试创建一个游戏，其中一个块来回移动，直到玩家按下空格。在此之后，块跳转到下一行并停止。

目前我遇到了碰撞代码问题。

shell抛出的错误是：

    if doRectsOverlap(j['rect'], floors['line']):
TypeError: list indices must be integers, not str

我很难理解代码出错的地方。我对python如何工作的了解非常有限。

当玩家跳跃时，还有一些代码我已经评论过与地板移动的下降。它已经被注释掉，直到我可以让碰撞工作，但仍然包括

以下代码：

import pygame, sys, time
from pygame.locals import *


def doRectsOverlap(rect1, rect2):
    for a, b in [(rect1, rect2), (rect2, rect1)]:
        # Check if a's corners are inside b
        if ((isPointInsideRect(a.left, a.top, b)) or
            (isPointInsideRect(a.left, a.bottom, b)) or
            (isPointInsideRect(a.right, a.top, b)) or
            (isPointInsideRect(a.right, a.bottom, b))):
            return True

    return False

def isPointInsideRect(x, y, rect):
    if (x > rect.left) and (x < rect.right) and (y > rect.top) and (y < rect.bottom):
        return True
    else:
        return False
