统一3D中字符隐藏不工作的碰撞检测

Question

我当时正在学习一个教程，但是CheckCollisionOverlap()函数出现了问题。这意味着在玩家蹲着的时候，检查球员头部是否有碰撞，但出于某种原因，他不会站起来(或停止原地行走)。

如果我评论PhysicsUpdate()和CheckCollisionOverlap()，他会蹲下，蹲下，站起来，所以我知道这个问题必须存在于这个逻辑中。

在教程注释部分，有人提到他们更改了层掩码的值。我命名了一个分层掩码Player，并将其分配给第8层，但这仍然没有起到任何作用。

Answer 1

我还必须改变玩家游戏对象中所有层次的孩子。不太清楚为什么会起作用，但它的反应。
