如何在屏幕上显示和更新分数? [英] How to display and update a score on screen?
问题描述
我的问题是关于显示和更新文本,以便在屏幕上显示分数.
我想创建一个像真实游戏一样出现在屏幕上的分数.但是经过谷歌的研究,我没有发现有人希望在屏幕上增加分数......
I would like to create a score like the real game that would appear on the screen. But after researching Google, I have not found anyone wishing to increase a score on the screen ...
确实,我希望每次鸟在管道之间经过时分数都会增加,因此每当管道的 X 为 67 像素时.那么有人知道怎么做吗?
Indeed, I would like the score to increase each time the bird passes between the pipes and therefore whenever the pipes have an X of 67 pixels. So does anyone know how to do this?

有人可以向我解释这个问题,因为我认为这很容易:(这是游戏的图片:)
Could someone explain the problem to me because I thought it would be easy :( Here are the pictures of the game :)
推荐答案
这是显示分数的一种方法:它使用 tk.Label
,即在分数增加的同时更新.
Here is one approach to display the scores: It uses a tk.Label
, that is updated at the same time the score increases.
增加分数的触发器当前是对on_change
的随机调用;如果管道 x 坐标低于鸟的 x 坐标(鸟成功越过障碍物),您可以将其修改为测试
The trigger that increases the score is currently a random call to on_change
; you can modify this to be a test if a pipe x coordinates becomes lower than the bird x coordinates (the bird successfully crossed the obstacle)
如果您想重新定位画布上的乐谱标签,您可以.
You can, if you want relocate the score label on the canvas.
import random
import tkinter as tk
WIDTH, HEIGHT = 500, 500
def create_pipes():
pipes = []
for x in range(0, WIDTH, 40):
y1 = random.randrange(50, HEIGHT - 50)
y0 = y1 + 50
pipes.append(canvas.create_line(x, 0, x, y1))
pipes.append(canvas.create_line(x, y0, x, HEIGHT))
return pipes
def move_pipes():
for pipe in pipes:
canvas.move(pipe, -2, 0)
x, y0, _, y1 = canvas.coords(pipe)
if x < 0:
canvas.coords(pipe, WIDTH+20, y0, WIDTH+20, y1)
if random.randrange(0, 20) == 10:
on_change()
root.after(40, move_pipes)
def on_change():
global score
score += 1
score_variable.set(f'score: {score}')
root = tk.Tk()
tk.Button(root, text='start', command=move_pipes).pack()
score = 0
score_variable = tk.StringVar(root, f'score: {score}')
score_lbl = tk.Label(root, textvariable=score_variable)
score_lbl.pack()
canvas = tk.Canvas(root, width=WIDTH, height=HEIGHT, bg="cyan")
canvas.pack()
pipes = create_pipes()
root.mainloop()
