MonoBehaviour.OnTriggerStay2D(Collider2D)

Description

Sent each frame where another object is within a trigger collider attached to this object (2D physics only).

Further information about the other collider is reported in the Collider2D parameter passed during the call.

Notes: Trigger events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.
