为什么我在 blit 图像时出现错误

问题描述

我正在尝试将敌人放入我正在制作的游戏中。但是当我运行该项目时，python 报告了“TypeError”

File "C:\Users\Zee_S\OneDrive\Desktop\python projects\lil Shooter\Player\Lil Shooter.py",line 153,in draw
    screen.blit(ZwalkRight[self.walkcount//3] (self.x,self.y))
TypeError: 'pygame.Surface' object is not callable
[Finished in 1.4s]

但我看了我的代码，它看起来不错

class Enemy(object):

    ZwalkRight = [pygame.image.load('ZR1.png'),pygame.image.load('ZR2.png'),]
    ZwalkLeft = [pygame.image.load('ZL1.png'),pygame.image.load('ZL2.png'),]
        
    def __init__(self,x,y,width,height,end):
        self.x = x
        self.y = y
        self.width = width
        self.height = height
        self.end = end
        self.path = [self.x,self.end]
        self.walkcount = 0
        self.velo = 3

    def draw(self,win):
        self.move()
        if self.walkcount + 1 <= 33:
            self.walkcount = 0

        if self.velo > 0:
            screen.blit(self.ZwalkRight[self.walkcount//3] (self.x,self.y))
            walkcount += 1
        else:
            win.blit(self.ZwalkLeft[self.walkcount //3] (self.x,self.y))
            walkcount += 1
    def move(self):
        if self.velo > 0:
            if self.x +  self.velo < self.path[1]:
                self.x += self.velo
            else:
                self.velo = self.velo * -1
                self.walkcount = 0
        else:
            if self.x - self.vel > self.path[0]:
                self.x += self.velo
            else:
                self.velo = self.velo * -1
                self.walkcount = 0

问题不可能是因为我在这里而忘记绘制图像

def redrawGameWindow():
    screen.blit(bg,(0,-100))
    man.draw(screen)
    zombie.draw(screen)
    for bullet in bullets:
        bullet.draw(screen)
    pygame.display.update()

    
    pygame.display.update()

man = Player(300,508,64,64)
zombie = Enemy(100,450)
bullets = []
run = True
while run:
     [...]

有人可以修复甚至解释为什么我会收到此错误

解决方法

您在调用 blit 时在右方括号后缺少一个逗号：

screen.blit(self.ZwalkRight[self.walkcount//3] (self.x,self.y))

screen.blit(self.ZwalkRight[self.walkcount//3],(self.x,self.y))
