跳入我的 pygame 程序不起作用 - 跳到屏幕顶部并低于平台

如何解决跳入我的 pygame 程序不起作用 - 跳到屏幕顶部并低于平台

我遇到这个问题已经有一段时间了，我一直在寻找解决方案并尝试了很多方法，但我所做的一切似乎都不起作用。发生的事情是，当我按下跳跃键时，精灵第一次跳得非常高，然后每次都正确跳跃但低于地面。我会尝试以某种方式附上视频来表达我的意思。

这是其中包含跳转的函数：

def level1():
    global running,jumping1,neg1
    global x1,y1,x2,y2,xChange1,yChange1,xChange2,yChange2,jump1,jump2,jumping2,isJump

    
    while running:
        clock.tick(FPS)
        
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    xChange1 = -5
                if event.key == pygame.K_RIGHT:
                    xChange1 = 5
                if event.key == pygame.K_UP:
                    if not jumping1:    
                        jumping1 = True
            if event.type == pygame.KEYUP:
                if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                    xChange1 = 0


            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_a:
                    xChange2 = -5
                elif event.key == pygame.K_d:
                    xChange2 = 5
                elif event.key == pygame.K_w:
                    yChange2 = -5
                elif event.key == pygame.K_s:
                    yChange2 = 5
            if event.type == pygame.KEYUP:
                if event.key == pygame.K_a or event.key == pygame.K_d:
                    xChange2 = 0
                elif event.key == pygame.K_s or event.key == pygame.K_w:
                    yChange2 = 0           

        if jumping1:
            if jump1 >= -25:
                neg1 = 1
                if jump1 <0:
                    neg1 = -1
                y1 -= (jump1 **2) * 0.5 * neg1
                jump1 -= 1
            else:
                jump1 = 10
                jumping1 = False
 
        x1 += xChange1
        x2 += xChange2
        y1 += yChange1
        y2 += yChange2

        gravity1(y1)
        
        screen.blit(game_image,(0,0))
        character1(x1,y1)
        character2(x2,y2)
        gameFloor(fx,fy)

        if x1 < 0:
            x1 = 0
        if x1 > WIDTH - Char1WIDTH:
            x1 = WIDTH - Char1WIDTH

        if y1 < 0:
            y1 = 0
        if y1 > HEIGHT - Char1HEIGHT - 50:
            y1 = HEIGHT - Char1HEIGHT - 50

        if x2 < 0:
            x2 = 0
        if x2 > WIDTH - Char2WIDTH:
            x2 = WIDTH - Char2WIDTH

        if y2 < 0:
            y2 = 0
        if y2 > HEIGHT - Char2HEIGHT-50:
            y2 = HEIGHT - Char2HEIGHT -50


            
        pygame.display.flip()

解决方法

问题是if jump1 >= -25:。如果跳转从 10 开始，则结束必须在 -10。对于更高的跳跃，您可以尝试 12。使用 jumpCount 设置开始并检查跳跃的结束：

jumpCount = 10   # <-- try 12 here
jump1 = jumpCount

def level1():
    # [...]

    while running:
        # [...]

        if jumping1:
            if jump1 >= -jumpCount:
                neg1 = 1
                if jump1 <0:
                    neg1 = -1
                y1 -= (jump1 **2) * 0.5 * neg1
                jump1 -= 1
            else:
                jump1 = jumpCount
                jumping1 = False
