贪吃蛇游戏分数不加

如何解决贪吃蛇游戏分数不加

这个蛇游戏代码。我想在这个游戏中添加系统分数。这样每次蛇吃他的分数都会增加。但是如果蛇没有得到食物分数不会增加。

如何显示当前分数？

解决方法

它已定义，但您必须调用 addscore() 函数。替换

if not food_collision():
    snake.pop(0)

与

if food_collision():
    addscore()
else:
    snake.pop(0)

,

您可以将此代码添加到您的游戏中。它会写一个分数：

score = 0
#Creating Score Writer
turtle.hideturtle()
turtle.penup()
turtle.color("white")
turtle.goto(-300,300)
turtle.write(f"Score = {score}",font=("Arial",16,"normal"))

为此您也不需要 screen.setup()。 您可以更改分数变量。每次你想要文本更新你写

turtle.clear()
turtle.write(f"Score = {score}","normal"))
