如何为此特定代码在 Pygame 中模拟跳跃 [英] How to simulate Jumping in Pygame for this particular code

问题描述

我一直在尝试模拟 Pygame 代码中的跳转，但未能成功实现.有一个尺寸为 10 x 10 的矩形，我希望该矩形在按下 SPACE 时跳转.我暂时保持这段代码不受重力影响.

I have been trying to simulate the jump in the Pygame code but haven't been able to successfully implement it. There is a rectangle of dimension 10 by 10 and I want that rectangle to jump when SPACE is press. I am keeping this code independent of gravity for now.

import pygame
pygame.init()
ScreenLenX = 1000
ScreenLenY = 500
win = pygame.display.set_mode((ScreenLenX, ScreenLenY))
pygame.display.set_caption("aman")
run = True
Xcord = 100
Ycord = 100
length = 10
height = 10
vel = 2
xmove = 1
ymove = 1
while run:
  #pygame.time.delay(1)
    for event in pygame.event.get():
        print(event)
        if event.type ==pygame.QUIT:

            run = False

    if keys[pygame.K_RIGHT] and Xcord <= ScreenLenX-length:
        Xcord += vel
    if keys[pygame.K_LEFT] and Xcord >= 0:
        Xcord -= vel

     if keys[pygame.K_UP] and Ycord >= 0:
            Ycord -= vel
     if keys[pygame.K_DOWN] and Ycord <= ScreenLenY - height:
            Ycord += vel
     win.fill((0, 0, 0))
    pygame.draw.rect(win, (255, 0, 0), (Xcord, Ycord, length, height))
    keys = pygame.key.get_pressed()


    pygame.display.update()
pygame.quit()

推荐答案

在主循环之前添加一个变量jump并将其初始化为0:

Add a variable jump and initialize it by 0, before the main loop:

jump = 0  
while run:
    # [...]

只有在允许玩家跳跃并停留在地面上时，才对 pygame.K_SPACE 做出反应.如果满足，则将 jump 设置为所需的跳跃"高度:

Only react on pygame.K_SPACE, if player is allowed to jump and stays on the ground. If this is fulfilled then set jump to the desired "jump" height:

if keys[pygame.K_SPACE] and Ycord == ScreenLenY - height:
    jump = 300

只要 jump 大于 0，在主循环中向上移动玩家并减少 jump 相同的量.
如果玩家没有跳到黎明，直到他落地:

As long as jump is greater than 0, move the player upwards and decease jump by the same amount, in the main loop.
If the player is not jumping that let him fall dawn, till he reaches the ground:

 if jump > 0:
    Ycord -= vel
    jump -= vel
elif Ycord < ScreenLenY - height:
    Ycord += 1

查看演示，我将建议应用于您的代码:

See the demo, where I applied the suggestions to your code:

import pygame
pygame.init()

ScreenLenX, ScreenLenY = (1000, 500)
win = pygame.display.set_mode((ScreenLenX, ScreenLenY))
pygame.display.set_caption("aman")
Xcord, Ycord = (100, 100)
length, height = (10, 10)
xmove, ymove = (1, 1)
vel = 2
jump = 0

run = True
clock = pygame.time.Clock()
while run:
    #clock.tick(60)
    for event in pygame.event.get():
        print(event)
        if event.type ==pygame.QUIT:
            run = False

    keys = pygame.key.get_pressed()
    if keys[pygame.K_RIGHT] and Xcord <= ScreenLenX-length:
        Xcord += vel
    if keys[pygame.K_LEFT] and Xcord >= 0:
        Xcord -= vel

    if keys[pygame.K_SPACE] and Ycord == ScreenLenY - height:
        jump = 300

    if jump > 0:
        Ycord -= vel
        jump -= vel
    elif Ycord < ScreenLenY - height:
        Ycord += 1

    win.fill((0, 0, 0))
    pygame.draw.rect(win, (255, 0, 0), (Xcord, Ycord, length, height))

    pygame.display.update()
