Объединив метод, использованный Josselin в этом сообщении Нажмите 2 клавиши одновременно для перемещения по диагонали tkinter? с вашей черепахой, которую мы можем захватить при нажатии нескольких клавиш и что делать об этом.
Этот код позволяет вам нажимать несколько клавиш одновременно, чтобы получить хотя бы вращательное движение.
import tkinter as tk
import turtle
window = tk.Tk()
window.geometry("750x500")
window.resizable(False, False)
pressedStatus = {"Up": False, "Down": False, "Left": False, "Right": False}
canvas = tk.Canvas(master=window, width=500, height=500, bg="white")
canvas.pack()
t = turtle.RawTurtle(canvas)
def pressed(event):
pressedStatus[event.keysym] = True
def released(event):
pressedStatus[event.keysym] = False
def set_bindings():
for char in ["Up", "Down", "Left", "Right"]:
window.bind("<KeyPress-%s>" % char, pressed)
window.bind("<KeyRelease-%s>" % char, released)
def animate():
if pressedStatus["Up"]: t.forward(1)
if pressedStatus["Down"]: t.back(1)
if pressedStatus["Left"]: t.left(1)
if pressedStatus["Right"]: t.right(1)
canvas.update()
window.after(10, animate)
set_bindings()
animate()
window.mainloop()
С чуть большей работой и другим словарем для отслеживания вращения мы можно получить диагональные линии в любой степени, которую вы хотите. Я предполагаю, что цель - 45 градусов, поэтому попробуйте следующее.
import tkinter as tk
import turtle
window = tk.Tk()
window.geometry("750x500")
window.resizable(False, False)
pressed_status = {"Up": False, "Down": False, "Left": False, "Right": False}
rotation_lock = {"Left": False, "Right": False} # use to lock the rotation event so we cont constantly rotate.
canvas = tk.Canvas(master=window, width=500, height=500, bg="white")
canvas.pack()
t = turtle.RawTurtle(canvas)
def pressed(event):
pressed_status[event.keysym] = True
def released(event):
pressed_status[event.keysym] = False
if event.keysym == 'Left' or event.keysym == 'Right':
rotation_lock[event.keysym] = False
def set_bindings():
for char in ["Up", "Down", "Left", "Right"]:
window.bind("<KeyPress-%s>" % char, pressed)
window.bind("<KeyRelease-%s>" % char, released)
def animate():
# By first checking if 2 keys are pressed we can make sure we get the rotation we are looking for.
# Then if not 2 keys then process single keys.
# We also want to lock the rotation after our first rotation as to not constantly turn at a 45 degree angle.
if pressed_status["Up"] and pressed_status["Left"]:
t.forward(1)
if not rotation_lock['Left']:
rotation_lock['Left'] = True
t.left(45)
elif pressed_status["Up"] and pressed_status["Right"]:
t.forward(1)
t.right(1)
if not rotation_lock['Right']:
rotation_lock['Right'] = True
t.right(45)
elif pressed_status["Down"] and pressed_status["Left"]:
t.back(1)
if not rotation_lock['Left']:
rotation_lock['Left'] = True
t.left(45)
elif pressed_status["Down"] and pressed_status["Right"]:
t.back(1)
if not rotation_lock['Right']:
rotation_lock['Right'] = True
t.right(45)
elif pressed_status["Up"]: t.forward(1)
elif pressed_status["Down"]: t.back(1)
elif pressed_status["Left"]: t.left(1)
elif pressed_status["Right"]: t.right(1)
canvas.update()
window.after(40, animate)
set_bindings()
animate()
window.mainloop()
Если мы добавим 3-й ключ к миксу, мы сможем переключаться между диагональными и изогнутыми линиями.
Взять посмотрите на этот пример:
import tkinter as tk
import turtle
window = tk.Tk()
window.geometry("750x500")
window.resizable(False, False)
pressed_status = {"Up": False, "Down": False, "Left": False, "Right": False, "Control_L": False}
rotation_lock = {"Left": False, "Right": False} # use to lock the rotation event so we cont constantly rotate.
canvas = tk.Canvas(master=window, width=500, height=500, bg="white")
canvas.pack()
t = turtle.RawTurtle(canvas)
def pressed(event):
pressed_status[event.keysym] = True
def released(event):
pressed_status[event.keysym] = False
if event.keysym == 'Left' or event.keysym == 'Right':
rotation_lock[event.keysym] = False
def set_bindings():
for char in ["Up", "Down", "Left", "Right", "Control_L"]:
window.bind("<KeyPress-%s>" % char, pressed)
window.bind("<KeyRelease-%s>" % char, released)
def animate():
# By first checking if 2 keys are pressed we can make sure we get the rotation we are looking for.
# Then if not 2 keys then process single keys.
# We also want to lock the rotation after our first rotation as to not constantly turn at a 45 degree angle.
if pressed_status["Up"] and pressed_status["Left"]:
t.forward(1)
if pressed_status["Control_L"]:
t.left(1)
else:
if not rotation_lock['Left']:
rotation_lock['Left'] = True
t.left(45)
elif pressed_status["Up"] and pressed_status["Right"]:
t.forward(1)
if pressed_status["Control_L"]:
t.right(1)
else:
if not rotation_lock['Right']:
rotation_lock['Right'] = True
t.right(45)
elif pressed_status["Down"] and pressed_status["Left"]:
t.back(1)
if pressed_status["Control_L"]:
t.left(1)
else:
if not rotation_lock['Left']:
rotation_lock['Left'] = True
t.left(45)
elif pressed_status["Down"] and pressed_status["Right"]:
t.back(1)
if pressed_status["Control_L"]:
t.right(1)
else:
if not rotation_lock['Right']:
rotation_lock['Right'] = True
t.right(45)
elif pressed_status["Up"]: t.forward(1)
elif pressed_status["Down"]: t.back(1)
elif pressed_status["Left"]: t.left(1)
elif pressed_status["Right"]: t.right(1)
canvas.update()
