Question

JavaScript => public function IsTouchingLayers(layerMask: int = Physics2D.AllLayers): bool;
C# => public bool IsTouchingLayers(int layerMask = Physics2D.AllLayers);

Parameters 参数

layerMask

Any colliders on any of these layers count as touching. 任意碰撞器接触层。

Returns 返回

bool Whether any of the collider(s) attached to this rigidbody are touching any colliders on the specified layerMask or not.

返回布尔值，任意附加到该刚体的碰撞器与指定层的碰撞器是否接触。

Description 描述

Checks whether any of the collider(s) attached to this rigidbody are touching any colliders on the specified layerMask or not.

检测附加到该刚体的任意碰撞器是否与指定层的碰撞器接触。

It is important to understand that checking if colliders are touching or not is performed against the last physics system update i.e. the state of touching colliders at that time. If you have just added a new Collider2D or have moved a Collider2D but a physics update has not yet taken place then the colliders will not be shown as touching. The touching state is identical to that indicated by the physics collision or trigger callbacks.

重要的是理解该检测，碰撞器是否接触被执行是针对上次物理系统更新。例如，在那时的接触状态，如果您只是新增了一个Collider2D或移动Collider2D，但物理更新尚未发生，那么该碰撞器不会接触。接触状态于通过物理碰撞或触发回调相同。
