Hi all,
I'm trying to understand how to make work an event "mouse_drag".
In fact my aim is to select boundary coordinates of a rectangular selection on the display and I was wondering if I can do this by using an event like that.
In particular I started modifying slightly the "Event Layer.gaml" example script, but if I put [mouse_drag] instead of [mouse_down] on one of the two actions defined in the script (rows 44 or 48), nothing happens.
How can I proceed? isn't it, the dragging action, there to select some agents?
all the best,
Annalisa
