Now when i run this game , the score keeps on updating.I want it to do like when the snake collides with 'foodimg',
it should add +1 to the score.Also sometimes even if the snake does not touch the food , the food is moved to a random
position.How do i fix this bug?

在这种情况下，分数总是处于上升状态，我想解决的问题是，当蛇没有与食物碰撞时，食物有时会移动到一个随机的位置。我该如何修复这两个错误？这是代码中使用的2个图像

如果你想在没有收集的情况下移动目标，请设置一个计时器，对每个刻度进行计数。如果计数器超过某个数字，则移动目标，如果玩家及时收集目标，则重置计数器。
希望这有帮助：）
