所以我在Tkinter制作游戏,但我想要做的是当我点击键盘上的一个按钮时,例如“w”,它会运行一个函数,例如将x增加5。

继承我的代码。

__author__ = 'Zac'
from Tkinter import *
from random import randint

class Application:
    def circle(self, r, x, y):
        return (x-r, y-r, x+r, y+r)

    def square(self, s, x, y):
        return (x, y, s, s)

    def __init__(self, canvas, r, x, y):
        self.canvas = canvas
        self.r = r
        self.x = x
        self.y = y
        self.ball = canvas.create_oval(self.circle(r, x, y))


root = Tk()
canvas = Canvas(root, width = 1000, height = 1000)
canvas.pack()

ball1 = Application(canvas, 20, 50, 50)


root.mainloop()

使用widget.bind方法将keypress与事件处理程序绑定。

例如:

....

ball1 = Application(canvas, 20, 50, 50)

def increase_circle(event):
    canvas.delete(ball1.ball)
    ball1.r += 5
    ball1.ball = canvas.create_oval(ball1.circle(ball1.r, ball1.x, ball1.y))

root.bind('<w>', increase_circle)  # <--- Bind w-key-press with increase_circle

root.mainloop()
