您好我一直试图找出碰撞检测。到目前为止，我已经设法编码它，以便当射弹接触到敌人的左下角时检测到碰撞。我希望在击中矩形的底部时检测到碰撞。
碰撞检测在move_shot()
这是整个代码
from tkinter import *
# creates window
window = Tk()
size = window.winfo_screenheight()
window.title("This is a window")
# set up geometry using string formatting operator %
window.geometry("%dx%d+%d+%d" % (1000, 1000, 10, 10))
window.update()
# creates canvas
global canvas
canvas = Canvas(window, bg='green')
# pack is a layout manager
canvas.pack(fill=BOTH, expand=1)
canvas.update()
canvas.create_rectangle(0, 1000, 1000, 0, fill="orange", width=10, outline="white", tag="border")

global loaded_gun
c = canvas.coords("player")
canvas.create_line(c[0],c[1] + 20,c[2],c[3],width=5,fill="yellow",tag="shot")
loaded_gun = 0
move_shot("shot") # furas

似乎检测工作正常。几乎无事可做。
我只会在离开屏幕时删除镜头。
在我再次运行loaded_gun == 0:之前，我会检查after()。
如果你继续跑步after loop下一次射击会有两个after loop，它会跑2倍。三次射击的速度将提高3倍。
我在我更改的地方添加了# furas。

好吧，没关系
我已经弄明白我只需要这样做
if shot[0] >= en[0] and shot[0] <= en[0] + 70:
