##    Shows how to parent a 3D tracker and EGP    ##
##    object to an entity in the world.           ##

    EGP:egp3DTracker( 1, vec() ) # place a 3d tracker with no offset
    EGP:egpParent( 1, Entity ) # parent the tracker to the entity
    
    EGP:egpCircle( 2, vec2(0,0), vec2(5,5) ) # create a circle at (0,0) (centered on the tracker)
    EGP:egpParent( 2, 1 ) # parent the circle to the tracker
    
    # Trackers are better for tracking entities in 3D since they partially run clientside (look mom, no runontick!)
    # Unfortunately, this means you can't use egpPos() to GET the position of trackers or their child objects
