我有一个工作太空射击游戏。基本设置。玩家控制左右移动的船只和子弹自动生成。我想在你达到一定分数后添加“老板”。
为了解决这个问题，如果得分== 5，我就可以使用，让精灵出现并移动
它没有工作，所以我把分数设为0，它产生并移动到它的位置。
我被困在我的身上。我的猜测是Boss Sprite和EnemyShips在它们产生时碰撞很多并且没有让Boss Sprite Spawn。
Boss精灵命名为tj.JPG
所以我添加了一个CollisonBitMask并将其设置为0，但这也没有用。
这是EnemyTimer的问题吗？我甚至设置了repeat = false来测试它并设置得分== 1并且它也没有任何影响。
任何帮助将不胜感激。我很想学会在达到所需分数后如何正确添加老板。
这是我的GameScene
