Question

我正在为一个学校项目开发一款陆地模拟游戏，而我拥有的跳跃代码不起作用。当我运行代码时，除非我移到侧面，否则角色会不断跳跃，但是当我按下空格键（实际的跳跃按钮时，角色会永久停止跳跃。

elif man.isJump != False:
    if keys[pygame.K_SPACE]:
        man.isJump = True
        man.right = False
        man.left = False
        man.walkCount = 0
    else:
        if man.jumpCount >= -10:
            # neg variable determines which way our character is moving positive 1 up, negative 1 down
            neg = 1
            if man.jumpCount < 0:
                neg = -1
            # move our character by the number of pixels 
            # using the product (**) of 10 which is count and halfing the value
            # if positive then moving up, negative moving down
            man.y -= (man.jumpCount ** 2) * 0.5 * neg
            man.jumpCount -= 1
        else:
            man.isJump = False
            man.jumpCount = 10

[...]运行代码时，角色不断跳动[...]

您必须评估男人是否没有跳跃，然后按 SPACE 来开始跳跃。在其他情况下，可以执行跳转：

if man.isJump == False:

    if keys[pygame.K_SPACE]:
        man.isJump = True # <------ start jump
        man.right = False
        man.left = False
        man.walkCount = 0

else  

    if man.jumpCount >= -10 and : # <----- is jumping?        
        # neg variable determines which way our character is moving positive 1 up,
        # negative 1 down
        neg = 1
        if man.jumpCount < 0:
            neg = -1
        # move our character by the number of pixels 
        # using the product (**) of 10 which is count and halfing the value
        # if positive then moving up, negative moving down
        man.y -= (man.jumpCount ** 2) * 0.5 * neg
        man.jumpCount -= 1

    else:
        man.isJump = False # <------ end jump
        man.jumpCount = 10

pygame角色跳跃在学校项目中不起作用
