在 pygame 中进行精灵跳跃

问题描述

我正在为我的 alevel 编程项目制作游戏，但遇到了一些麻烦。我在让我的精灵跳跃时遇到了麻烦。我找到了一些代码和视频，告诉您如何操作，我按照步骤操作，但似乎不起作用？我已经盯着 (***) 代码所在的部分用于跳转

def level1():
    global running,jumping1
    global x1,y1,x2,y2,xChange1,yChange1,xChange2,yChange2,jump1,jump2,jumping1,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 not jumping1:
                    if event.key == pygame.K_UP:
                        jumping1 = True
                    else:
                        if jump1 >= -10:
                            y1 -= (jump1 **2) * 0.5
                            jump1 -= 1
                        else:
                            jump1 = 10
                            jumping1 = False
********************************************************************************
            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           

        x1 += xChange1
        x2 += xChange2
        y1 += yChange1
        y2 += yChange2

        y1 -= gravity1
        y2 -= gravity2
        
        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()

jumping 1 预先设置为false，jumping 1 设置为5

解决方法

没有更多细节很难说，但第一个 else 不应该与 if not jumping1: 具有相同的缩进吗？像这样：

if not jumping1:
    if event.key == pygame.K_UP:
        jumping1 = True
else:
    if jump1 >= -10:
        y1 -= (jump1 **2) * 0.5
        jump1 -= 1
    else:
        jump1 = 10
        jumping1 = False
