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?

如果您想移动目标（如果没有收集），请设置一个计时器，计算每个滴答。如果计数器超过一定数量，则移动目标，如果玩家及时收集目标重置计数器。
希望这会有所帮助：）
