類型錯誤：不受約束的方法player_init（）必須與Player實例被稱爲第一個參數（代替了INT實例）

Question

import pygame 
pygame.init() 

width, height = 1000, 700 
window = pygame.display.set_mode((width, height)) 

class Player: 
    def __init__(self, x, y): 
     self.pos_x = x 
     self.pos_y = y 
     self.width, height = 1000, 700 
     self.window = pygame.display.set_mode((width, height)) 

    def player_init(self): 
     sprite = pygame.image.load("Character Sprite.png") 
     self.window.blit(sprite, (self.pos_x, self.pos_y)) 

while 1: 
    Player.player_init(500-38, 350-49) 

我一直在四處尋找一點點，但我似乎無法找到答案，爲什麼這種類型錯誤

TypeError: unbound method player_init() must be called with Player instance as first argument (got int instance instead)

不管彈出什麼時候我創建一個類。

Answer 1

您需要做Player(x, y).player_init()，因爲player_init也需要self參數，它也使用__init__中指定的變量。您還使用2個參數調用player_init，但它只接受一個參數。

Answer 2

優先（while之前）創建Player類的實例預計參數

player = Player(500-38, 350-49) 

，並在以後使用它（但不帶參數）

player.player_init() 

---

但對我來說你的代碼看起來應該這樣

import pygame 

# --- constants --- (UPPER_CASE names) 

WIDTH = 1000 
HEIGHT = 700 

# --- classes --- (CamelCase names) 

class Player: 
       # <- empty line to make code more readable 
    def __init__(self, x, y): 
     self.image = pygame.image.load("Character Sprite.png") 
     self.rect = self.image.get_rect() 
     self.rect.x = x 
     self.rect.y = y 

    def draw(self, surface): 
     surface.blit(self.image, self.rect) 

# --- functions --- (lower_case names) 

# empty 

# --- main --- 

# - init - 

pygame.init() 
window = pygame.display.set_mode((WIDTH, HEIGHT)) 

# - objects - 

player = Player(500-38, 350-49) 

# - mainloop - 

while True: 

    # other code 

    player.draw(window) 

self.rect是非常有用的設置位置即。 self.rect.center，它有檢查衝突的功能。 player.rect.collidrect(enemy.rect)或player.rect.collidpoint(mouse_pos)

有用類pygame.spripte.Group()預計self.rect和self.image自動繪製所有的精靈。

    pygame.display.flip() # add to out image from display
