尝试通过玩家输入使物体在网格中移动

Question

所以我在tkinter开发一个类似地下城爬虫的游戏，而不是pygame。我发现这非常困难，因为网格无法在代码中工作，而且我也无法在画布上创建一个由关键输入移动的形状。我已经尝试了多种修复方法，但无法实现所有这些功能的组合。如果我能找到一些帮助，使一个网格，也允许一个形状移动的球员的输入，将有助于大部分。这段代码有很多错误，因为我还是一个非常新的初学者，这对于第一个游戏来说可能太过雄心勃勃了。在

正如Bryan所说，您可以使用画布的move方法。下面是一个简单的例子，玩家是一个红色的圆圈，你可以用键盘箭头在画布上移动。您可以向move_player函数添加其他键来实现游戏中的其他操作。在

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)

    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 = Game()
    game.mainloop()
