public static bool IsTouching (Collider2D collider1, Collider2D collider2);

参数

collider1 The Collider to check if it is touching collider2.
collider2 The Collider to check if it is touching collider1.

返回

bool collider1 是否正在接触 /collider2/。

描述

Checks whether the passed Colliders are in contact or not.

It is important to understand that checking whether Colliders are touching or not is performed against the last physics engine update; that is 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. This function returns the same collision results as the physics collision or trigger callbacks.


public static bool IsTouching (Collider2D collider, ContactFilter2D contactFilter);

参数

Collider The Collider to check if it is touching any other Collider filtered by the contactFilter.
contactFilter 接触筛选器,用于以不同方式筛选结果,例如按层遮罩、Z 深度或法线角度。

返回

bool Whether the Collider is touching any other Collider filtered by the contactFilter or not.
