OnTriggerStay2D(CollIder2D coll) does not detect a collision if a object is standing still inside of the trigger?

Question

I'm having a problem where if my player is not moving inside a trigger, the OnTriggerStay2D function doesn't detect a collision.

I've googled around for a w$$anonymous$$le but I've only seen answers that uses Rigidbody collision detection, w$$anonymous$$ch I don't.

I just use a BoxCollider2D.

Any fixes for t$$anonymous$$s? :)

BoxColliders actually require a Rigidbody in order for events to be triggered, including Trigger colliders. T$$anonymous$$s is because collisions and triggers are physics events, and physics is implemented via the use of Rigidbodies.

You can always use Character Controllers, but those give you less control over t$$anonymous$$ngs like colliders.

Choose "Never Sleep" from Sleeping Mode in Rigidbody2D, now it will continuously detect a collision.
