这是一个' Chase'过去几个月我一直在涉猎的风格游戏 任何人都可以帮我为我的精灵创建边框吗?我设法使用clamp_ip()方法,但它只停止图像离开屏幕而不是实际的精灵,所以我把它拿出来了。任何帮助将不胜感激。
答案 0 :(得分:0)
player
精灵的实际位置存储在self.position
属性中,但调用player.rect.clamp_ip(border_rect)
仅影响self.rect
属性,而position
仍会每一帧都要改变。
我使用pygame.Rect.contains
方法检查播放器是否在屏幕区域之外,如果是,请拨打clamp_ip
并将player.position
设置为新{{1} }}
player.rect.center
