Question by MegaSmiley2 · Sep 22, 2015 at 10:41 AM · positioningcoordinates

Using real world coordinates in Unity ?

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.

$$anonymous$$eep in $$anonymous$$d that GPS is not very accurate depending on how many satellites there are in range and what's their relative position. Sometimes it's very accurate (+- a few meters) sometimes it's extremely bad (+-100m or even worse).

It depends on for what purpose you need the position and what's your acceptable tolerance. Do you make some kind of Geocaching App?

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 : http://docs.unity3d.com/ScriptReference/Collider.OnCollisionEnter.html. 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
 
 }
