如何更改代码，使播放器停在边缘而不是环绕? [英] How do i change the code so that the player stops at the edges rather than wrapping around?

问题描述

WIDTH = 800
HEIGHT = 500

background = Actor("background")
player = Actor("player")
player.x = 200
player.y = 200

def draw():
screen.clear()
background.draw()
player.draw()

def update():
if keyboard.right:
    player.x = player.x + 4
if keyboard.left:
    player.x = player.x - 4
if keyboard.down:
    player.y = player.y + 4
if keyboard.up:
    player.y = player.y - 4

if player.x > WIDTH:
    player.x = 0
if player.x < 0:
    player.x = WIDTH
if player.y < 0:
    player.y = HEIGHT
if player.y > HEIGHT:
    player.y = 0

我想让播放器停在边缘而不是环绕并传送到另一侧.帮助将不胜感激.

I want to make the player stop at the edges instead of wrapping around and teleporting to the other side. Help would be very appreciated.

推荐答案

您的解决方法不正确:

if player.x > WIDTH:
    player.x = WIDTH
if player.x < 0:
    player.x = 0
if player.y < 0:
    player.y = 0
if player.y > HEIGHT:
    player.y = HEIGHT
