python - Pygame动画居中问题

问题描述

视频

我不确定为什么我的攻击动画低于敌人的其他动画。每次它攻击它y似乎更低。我不知道为什么，即使我把它们都集中在一起。

player_rect = player_image.get_rect(center = self.get_rect().center)
player_rect.centerx += 0
player_rect.centery += -6
window.blit(player_image, player_rect)

我的敌人类：

    def __init__(self,x,y,height,width,color):
        self.x = x
        self.y = y
        self.height = height

        self.upshot = [pygame.image.load("rawlk (" + str(i) + ").png").convert_alpha() for i in range(1, 12)]

解决方案

并非所有用于动画的帧看起来都具有相同的高度。为了弥补这一点，由于老鼠在地板上，您需要定义矩形 ( midbottom) 的底部，而不是中心：

player_rect = player_image.get_rect(center = self.get_rect().center)

player_rect = player_image.get_rect(midbottom = self.get_rect().midbottom)
window.blit(player_image, player_rect)

注意，如果动画帧大小不同或者老鼠在精灵上的位置发生变化，老鼠在游戏中的位置也会在动画期间发生变化。
