你是否注意到这里有一个子弹故障（一次性射出多个子弹）

碰撞/玩家类

要判断子弹是否击中妖精或者妖精是否碰到玩家

主要逻辑：
如果子弹的 x 和 y 坐标位于敌人的命中框中，我们就说这些物体发生了碰撞。

if bullet.y - bullet.radius < goblin.hitbox[1] + goblin.hitbox[3] and bullet.y + bullet.radius > goblin.hitbox[1]: # Checks x coords
    if bullet.x + bullet.radius > goblin.hitbox[0] and bullet.x - bullet.radius < goblin.hitbox[0] + goblin.hitbox[2]: # Checks y coords
        goblin.hit() # calls enemy hit method
        bullets.pop(bullets.index(bullet)) # removes bullet from bullet list
