游戏按钮get.pressed()

Question

我只是刚开始玩游戏，这是我的代码，小片。我有主按钮功能，在gameloop中我成功地创建了一个交互式按钮，我不知道如何按下游戏中的按钮(“开始播放”)并填充我的gameDisplay，以获取example...white颜色。提前感谢........................................................................................................................

Answer 1

您可以使用状态变量(True/False)来控制要显示的元素，并且可以使用按钮更改这些变量。

举个例子

    display_text = True
    display_button_1 = True
    display_button_2 = False

以控制何时显示文本和两个按钮。

第一个按钮更改值，它隐藏文本和第一个按钮，并显示第二个按钮。

有一个问题-你的按钮功能是丑陋的，它使用get_buttons()，所以当我按住按下按钮，我移除一个按钮，把另一个放在同一个地方，然后它自动点击第二个按钮。您应该使用event.type == MOUSEBUTTONUP (建议@Hilea)来修复这个问题。

        pygame.draw.rect(gameDisplay, ac,(x,y,w,h))

我希望这个项目能有所帮助。

import pygame,sys
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((400,400))
white=(255,255,255)
blue=(0,0,255)
bright_red = (255,0,0)
red = (200,0,0)
black=(0,0,0)
color=white

def changecolor(newcolor):
    global color
    color=newcolor

while True:
    screen.fill(color)

    for event in pygame.event.get():
        if event.type == QUIT:
            pygame.quit()
            sys.exit()
        elif event.type == MOUSEBUTTONUP:
            # Whenever somebody clicks on the screen the color
            # will change from the initial color to the color
            # value you send to the function. Using this you could
            # make it specifically for your button. Like calling
            # the change color function whenever the button is clicked.
            changecolor(blue)

    pygame.display.update()
