我正在开发一个简单的游戏和小圆圈“系统”。我希望能够单击每个系统，以便稍后在游戏中使用它做更多事情，但我很难识别仅单击一次。我将随机生成的坐标传递给字典，然后应使用鼠标位置检查每个矩形的碰撞，但由于某种原因不再起作用。任何帮助表示赞赏。

这是一些更相关的代码。

    for i in range(NumSystems):

    SysSize = random.randint(3,SystemSize)
    SysY = random.randint(SystemSize*2,GVPHEIGHT-SystemSize*2)
    SysX = random.randint(OverLayWidth+SystemSize*2,WINWIDTH-SystemSize*2)



    SysList[str('SysNum')+str(i)] = ((SysSize,(SysX,SysY)))
    SysCoords[str('SysNum')+str(i)] = pygame.draw.circle(DISPLAYSURF, WHITE, (SysX,SysY), SysSize, 0)

    pygame.display.update()

    #time.sleep(.25)


#Code above is putting the random Coords into a dictionary.
while True:
    MousePos=mouse.get_pos()
    for event in pygame.event.get():
        if event.type == QUIT:
           pygame.QUIT()
           sys.exit()
        elif event.type == KEYDOWN:
            # Handle key presses

            if event.key == K_RETURN:
                #Restarts the map
                main()
        elif event.type == MOUSEBUTTONDOWN:
            if event.button == 1:
                SysClicky(MousePos)
                if SysClicked == True:
                    print('Clicked System')
                elif SysClicked == False:
                    print('Something Else Clicked')






def SysClicky(MousePos):

for i in range(NumSystems):
    print('Made to the SysClicky bit')
    if SysCoords['SysNum'+str(i)].collidepoint(MousePos):
        SysClicked = True
        print(SysClicked)
        return SysClicked
    else:

        SysClicked = False
        return SysClicked

我不清楚 SysList / SysX/Y, SysCoords 是什么。它是否包含 SysCoords 中项目的宽度、高度？如果是这样，那已经在Rect()

下面systems是你dict的Rects。

这是代码：

def check_collisions(pos):
    # iterate dict, check for collisions in systems
    for k,v in systems.items():
        if v.collidepoint(pos):
            print("clicked system:", k)
            return

    print("clicked something else")

while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()

    elif event.type == MOUSEBUTTONDOWN:
        if event.button == 1:
            check_collisions(event.pos)

    # render

Pygamerect对象有一个collidepoint内置方法，它接受一个坐标并根据碰撞返回一个布尔值。您可以将鼠标坐标输入到函数中，如下所示：

MousePos=mouse.get_pos()
if mySurface.get_rect().collidepoint(MousePos):
    doSomething()
