Pygame Keyup/Keydown

问题描述

我正在为我学校的计算机俱乐部制作一些Mario. (以及，作为团队的一部分.)无论如何，我在使用"keyup/keydown"命令时遇到了一些麻烦.这是我的代码:

I'm making a little Mario for my school's Computer Club. (well, as part of a team.)Anyway, I'm having some trouble with the "keyup/keydown" commands. Here's my code:

# 1 - Import library
import pygame
from pygame.locals import *

# 2 - Initialize the game
pygame.init()
width, height = 1280, 1000
screen=pygame.display.set_mode((width, height))
keys = [False, False, False, False]
playerpos=[100,100]

# 3 - Load images
player = pygame.image.load("images/totallynotgodzilla.png")
# 3.1 - Load Audio
music = pygame.mixer.Sound("audio/skyrim.wav")

# 4 - keep looping through
while 1:
    # 5 - clear the screen before drawing it again
    screen.fill(0)
    # 6 - draw the screen elements
    screen.blit(player, playerpos)
    # 7 - update the screen
    pygame.display.flip()
    # 8 - loop through the events
    for event in pygame.event.get():
        if event.type == pygame.KEYDOWN:
            if event.key==K_w:
                keys[0]=True
            elif event.key==K_a:
                keys[1]=True
            elif event.key==K_s:
                keys[2]=True
            elif event.key==K_d:
                keys[3]=True
        if event.type == pygame.KEYUP:
            if event.key==pygame.K_w:
                keys[0]=False
            elif event.key==pygame.K_a:
                keys[1]=False
            elif event.key==pygame.K_s:
                keys[2]=False
            elif event.key==pygame.K_d:
                keys[3]=False

        # 9 - Move player
        if keys[0]:
            playerpos[1]-=5
        elif keys[2]:
            playerpos[1]+=5
        if keys[1]:
            playerpos[0]-=5
        elif keys[3]:
            playerpos[0]+=5

基本上，问题是当我按下一个键时，它会等待keyup命令发生，然后再次移动.所以基本上我必须快速按下按钮才能移动.

Basically, the problem is that when I press a key down, it waits for the keyup command to happen before moving again. So basically I have to rapidly press down the buttons to move.

我删除了一些代码，所以如果有什么遗漏，请告诉我，我会告诉你是否有.

I deleted some of the code, so if something is missing, let me know and I'll tell you whether or not I have it.

推荐答案

缩进问题.您需要在主游戏循环中而不是在事件循环中测试关键状态.您需要UNINDENT键状态测试一级.

Indenting problem. You need to test your key states in you main game loop not in your event loop. You need to UNINDENT your keystate test one level.

while 1:
    # do init stuff
    screen.fill(0)
    # .... (all main loop init stuff here)

    for event in pygame.event.get():
        # test events, set key states
        if event.type == pygame.KEYDOWN:
            if event.key==K_w:
                keys[0]=True
        # .... (all event stuff)

    # Indent moves back to main game loop
    # test key states here...
    if keys[0]:
        playerpos[1]-=5
    elif keys[2]:
        playerpos[1]+=5
    # .... (and so on)
