如何将鼠标锁定在游戏窗口的边框中并在单击 ESKAPE 时将其解锁

Question

我想让我的鼠标不可见并停留在屏幕上。当我单击“ESCAPE”时，我想解锁鼠标，使其可见并暂停游戏。然后，当我在窗口中单击鼠标时，我想让鼠标不可见并再次留在屏幕中。

这是我的程序：

import pgzrun
import pygame

WIDTH = 800
HEIGHT = 600

def start():
    global exit, playing
    exit = False
    playing = True
    pygame.mouse.set_visible(False) #set my mouse invisible
    #here I want to write a code witch will block my mouse in the borders

def update():
    global exit, playing
    if keyboard.Escape:
        exit = True
    if exit:
        pygame.mouse.set_visible(True) #set my mouse visible
        #here I want to unblock it
        playing = False
        if mouse.LEFT:
            playing = True
    if playing:
        start()

def draw():
    if exit:
        screen.draw.text("Paused", (200, 200), color=(255,255,255), fontsize=60)
        screen.draw.text('Press in the screen to continue', (200, 250), color=(255,255,255), fontsize =60)

pgzrun.go()

我不知道如何在屏幕边框中设置鼠标阻挡。

Answer 1

您可以使用

pygame.event.set_grab(True)

函数将光标限制在 pygame 窗口内。要再次释放光标，只需使用

pygame.event.set_grab(False)

。
