public bool IsTouching (Collider2D collider);

Parameters

colliderThe collider to check if it is touching this collider.

Returns

bool Whether this collider is touching the collider or not.

Description

Check whether this collider is touching the collider or not.

It is important to understand that checking whether colliders are touching or not is performed against the last physics system 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 bool IsTouching (Collider2D collider, ContactFilter2D contactFilter);

Parameters

colliderThe collider to check if it is touching this collider.
contactFilterThe contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle.

Returns

bool Whether this collider is touching the collider or not.

Description

Check whether this collider is touching the collider or not with the results filtered by the ContactFilter2D.

public bool IsTouching (ContactFilter2D contactFilter);

Parameters

contactFilterThe contact filter used to filter the results differently, such as by layer mask, Z depth, or normal angle.

Returns

bool Whether this collider is touching the collider or not.

Description

Check whether this collider is touching other colliders or not with the results filtered by the ContactFilter2D.
