試圖讓一個對象通過玩家輸入與tkinter移動

Question

因此，我正在開發一個類似tkinter遊戲的地牢爬行器，而不是pygame。我發現它非常困難，因爲網格不能在代碼中工作，並且我無法找到在畫布上創建可通過鍵輸入移動的形狀的方法。我已經嘗試了多種修復方法，但無法實現這種方式。如果我能找到一些幫助製作一個網格，也可以通過玩家的輸入來移動形狀，這對大多數人都有幫助。這段代碼有很多錯誤，因爲我仍然是一個非常新的初學者，這可能對第一場比賽來說太過雄心勃勃。

正如Bryan所說，你可以使用畫布的move方法。下面是一個簡單的例子，玩家是一個紅色的圓圈，你可以用鍵盤箭頭在畫布上移動。您可以將其他鍵添加到move_player函數來實現遊戲中的其他操作。

import tkinter as tk 

class Game(tk.Tk): 
    def __init__(self): 
     tk.Tk.__init__(self) 
     self.can = tk.Canvas(self, width=200, height=200) 
     self.can.pack(fill="both", expand=True) 
     self.player = self.can.create_oval(50,50,70,70, fill="red") 
     self.bind("<Key>", self.move_player) 
     self.mainloop() 

    def move_player(self, event): 
     key = event.keysym 
     if key == "Left": 
      self.can.move(self.player, -20, 0)   
     elif key == "Right": 
      self.can.move(self.player, 20, 0)  
     elif key == "Up": 
      self.can.move(self.player, 0, -20)   
     elif key == "Down": 
      self.can.move(self.player, 0, 20) 

if __name__ == '__main__': 
    Game()
