Am I able to use this function to add some more code in 'World', like add more model, or bind a model with given location.
P.S. I did search before asking. The only post I've found related is the one below, which is still unanswered. So I post mine with a little more question
You can use this methods to inject a 'fake' GPS position. This can become necessary when your ARchitect World should use a fixed reference point to start from e.g. a game at a specific monument or place. But in general you don't have to use this method if you don't have to.
After you've injected a new location the 'onLocationChanged' callback will be triggered and all your currently existing drawables will be redrawn, reflecting the new location.
