你如何添加碰撞，让我的敌人在Pygame中走得更慢？

Question

我做了一个游戏，玩家必须躲避被称为敌人的东西。我试过做碰撞，但没有运气，我不知道如何让敌人走得更慢。以下是我目前掌握的情况：

import pygame,random, sys
    from pygame.locals import *
    from Player import *
    from Person import *
    from Badies import *
    def terminate():
        pygame.quit()

    def writeText(window, written, cenX, cenY):
        font = pygame.font.Font(None, 48)
        text = font.render(written, 1, TEXTCOLOR)
        textpos = text.get_rect()
        textpos.centerx = cenX
        textpos.centery = cenY
        window.blit(text, textpos)
        return (textpos)

    def waitForPlayerToPressKey():
        while True:
            for event in pygame.event.get():

        #  draw your person with the correct image
        def draw(self, window):

        def moveDown(self):

        def playerHitFoes(playerRect, foes):

Answer 1

如果不能访问gif，也不能运行这段代码，我将假设您的问题在于如何检查冲突。你知道吗

也就是说，colliderect()函数接受一个参数，它应该是pygame.Rect()对象。你知道吗

意思是当您执行playerHitFoes操作时，您应该传递.rect对象的f['rect']对象，如下所示：

def playerHitFoes(playerRect, foes):
    for f in foes:
        if playerRect.colliderect(f['rect'].rect):
            return True
def playerHasHitHeart(playerRect, foes):
    for h in heart:
        if playerRect.colliderect(h['rect'].rect):
            return True

这可能会也可能不会解决您的问题。
但我将谈到我发现的其他一些东西，它们很可能对这个问题并不重要，但可能会给你带来问题。你知道吗

def playerHitFoes(playerRect, foes):
    for f in foes:
        if guy.getRect(f['rect']):
            return True
    return False

在上面的代码中，playerRect从未被使用过，guy没有被定义（尽管它很可能会把guy = Player()拉得很好，但这可能会给您带来问题。你知道吗

playerHitFoes()也定义了两次，一次在野外，一次在player函数中。但它从未在代码示例中使用过。你知道吗

playerHitFoes、playerHasHitHeart和collide?在代码的任何地方都不会被调用。你知道吗

playerHasHitBaddie用于检查game is over，但playerHasHitBaddie从未定义。你知道吗

即使我有GIF，这个代码也会给出很多例外情况。
所以我假设这只是你代码的一小部分，你遗漏了很多东西。。所以，要么以上解决了问题-或者你至少需要给我更多的细节。。例如，您使用什么代码来执行实际的碰撞检测？你知道吗

未定义或未使用的事物列表

• Badies()-我们不知道它是什么样子
• foes.drawAndCollision
• playerHasHitBaddie
• playerHitFoes
• playerHasHitHeart
• collide
• gameWin
• changedRecs
• PLAYERMOVERATE
• BADDIEMINSPEED
• BADDIEMINSIZE
• FPS
• win
• guy，TEXTCOLOR（函数中的局部变量假设全局存在）

这只是举几个例子。
一个重要的问题是Badies()是什么样子，以及如何检查/调用冲突检测。你知道吗
