为什么文本会缩放？

如何解决为什么文本会缩放？

我试图在玩家角色旁边移动一个文本，但它的缩放比例很奇怪...... 这是玩家角色的图片，旁边有文字“test”：

它应该是某种抗锯齿，因为它在移动文本的代码中是关闭的：

import pygame,sys
from pygame.locals import *


class MovingText(): 
 
    def __init__(self,text,font_size,color,surface,target,off_1,off_2): 
        self.font       = pygame.font.SysFont(None,font_size)
        self.textobj    = self.font.render(text,color) 
        self.textrect   = self.textobj.get_rect()
        self.surface    = surface  
        self.target     = target 
        self.offset     = (off_1,off_2)
        self.textrect.center = self.target_pos() 
         
    def update(self): 
        self.textrect.center = self.target_pos() 
        self.surface.blit(self.textobj,self.textrect.center)
         
    def target_pos(self): 
        pos = self.target.rect.center 
        return pos[0] + self.offset[1],pos[1] + self.offset[0]

我认为导致问题的原因是文本被创建时，这里：

self.follow_text = movingtext.MovingText('test',10,(255,255,255),self.display,self.player,5)

如果你认为这是其他的东西，你可以自由地检查其余的代码，不要真的这么认为，但我已经被证明错了一两次：

解决方法

当您在表面上绘制文本并将表面缩放到窗口大小时，文本会被缩放。您必须直接在显示面上绘制文本。
