每次矩形与其他矩形碰撞时，我的分数都会增加很多

如何解决每次矩形与其他矩形碰撞时，我的分数都会增加很多

所以我试图做到这一点，如果我的矩形与另一个矩形/点碰撞，它会将点 y 位置从矩形移开，并将一个添加到我的分数中。我遇到的问题是，当我的矩形与我的点 https://gyazo.com/d9e4167f749f2a672fe7f713ce5bab2e 碰撞时，我的分数将增加两个而不是一个。我曾尝试使用真假陈述使其仅在我的分数中添加一个而不是两个，但这也不起作用。我也尝试过使用计时器来告诉它何时添加，但这对我不起作用。

这是我试过的

    if point:
        score += 1
        text = font.render(""+str(score),True,(0,0))
        point = False
        
    # Making the rectangles get off the screen for a short amount of time
    if Ptimer > 0:
        Ptimer += 1
        point1.y = -200
    if Ptimer >= 15:
        Ptimer = 0
        

    if Ptimer2 > 0:
        Ptimer2 += 1
        point2.y = -200
    if Ptimer2 >= 20:
        Ptimer2 = 0

    # The player collideing with the point's
    if playerman.rect.colliderect(point1.rect):
        Ptimer = 1
        point = True

    if playerman.rect.colliderect(point2.rect):
        Ptimer2 = 1
        point = True

解决方法

当您将对象移出可见区域时，您更改了该对象的 y 属性：

point1.y = -200

但是您使用 rect 属性进行碰撞测试：

if playerman.rect.colliderect(point1.rect):

因此，在执行下一次碰撞测试之前，您需要在更改 rect 属性后更新 y 属性：

if Ptimer > 0:
    Ptimer += 1
    point1.y = -200
    point1.rect.topleft = (point1.x,point1.y)
