如何在 Pygame 中为此特定代码模拟跳跃 [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,但一直未能成功实现.有一个尺寸为 10 x 10 的矩形,我希望该矩形在按下 SPACE 时跳跃.我现在让这个代码独立于重力.
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
并初始化为0:
Add a variable jump
and initialize it by 0, before the main loop:
jump = 0
while run:
# [...]
仅对 pygame.K_SPACE
做出反应,如果允许玩家跳跃并留在地面上.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
相同的数量.
如果玩家没有跳跃,让他在黎明前坠落,直到他到达地面:
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,其中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()
