using focus_on in GAML

[Srirama Bhamidipati]

Hi,

I would like to fix the extent my display to focus on an agent. I first tried camera_pos and camera related display options, but this works only for OpenGL? I am trying to do it for java2D and GAMA pop-up suggests that I should use focus_on. But I do not know where should I use focus_on?

I used focus_on in the interactive console and it works. Can I somehow use focus_on in a display definition? 

thank you

Mmm I don't think you can do that 

Just to be curious? why not doing it in Opengl?

Hi Arnaud,

Opengl camera definition has just two many parameters to define. (position, up vector, look, etc etc) while focus on is just simple and almost does the equivalent

Secondly, I have a heavy simulation and opengl makes it more heavier

thirdly, I am just interested in top view of a few small regions of the whole world.

But my main question is that focus_on is a gaml operator that works in interactive console but not in GAML file. I wonder why or its use is just not documented yet?
