I have a Player controlled 2D object which has a CircleCollider2D and RigidBody2D. When I click the mouse, forces are added to the RigidBody2D and the CircleCollider2D is set to a Trigger so the Player dashes towards the mouse click’s location.
I have enemy 2D objects with their own CircleCollider2Ds and they are listening for TriggerEnter from the Player character while dashing.
This all works, unless the Player object is immediately touching the Enemy object and dashes through the enemy, no collisions are detected in this situation.
