I was wondering if it’s possible to have Unity check a the coordinates of where a person is standing in the real world so that if the person is in a specific spot or area around the spot it will display like a image or a video on the screen.
This would be done for mobile or iPad incase that makes any differences.
I don’t build on mobile but from other posts I’ve seen plenty of topics asked and answered about using native device APIs like GPS tracking which sounds like what you are after.
Search for other posts on that thread.
This isn’t a very specific question.
If you are talking about some sort of trigger system, use a mesh collider with the OnCollisionEnter method : Unity - Scripting API: Collider.OnCollisionEnter(Collision). When the player walks into the collider (make it a Trigger collider so that no collisions actually happen), you can do what you like.
Or for matching the location.
if (this.transform.position == otherTransformsPosition )
{
// Do anything you like
}
