Which method would you use to detect a collision with another GameObject that does not utilize a trigger collider?

Using the OnCollisionStay method is appropriate for detecting a collision with another GameObject that does not utilize a trigger collider. This method is specifically designed to handle ongoing collisions between two GameObjects that have regular colliders. When an object is continuously colliding with another, OnCollisionStay is invoked once per frame for every collider attached to the GameObject that is in contact, allowing for effective handling of physics interactions during that sustained collision.

This is particularly useful for scenarios where you need to perform actions based on the persistent contact with another GameObject, such as applying forces or changing states while the objects remain colliding. The method provides access to the collision data, which can give detailed information about the interaction, like the point of contact and the relative velocity of the colliding objects.

The other methods listed do not align with the requirement of detecting collisions with non-trigger colliders. For example, OnTriggerStay deals with trigger colliders, which do not cause physical collisions in the same way and serve different purposes in game design, primarily for detection without enabling physical interactions. OnMouseDown is used for detecting mouse input and is not related to collisions. Lastly, OnCollisionExit tracks when a collision ends rather than when it is sustained, making it unsuitable for ongoing
