Re: [Jaslibrary-support] Interface IColored

[Michele S. <son...@di...>]

The jas.space.MultiObjGrid contains an array of object for each cell.
It is a problem for the LayerObjGridDrawer constructor, which looks for=20
IColored objects in each cell.

The jas.plot package contains a special drawer for the MultiObjGrid=20
objects: the jas.plot.LayerMultiObjectGridDrawer.

In order to plot IColored agents - using the MultiObjGrid - you have to use=
=20
the LayerMultiObjectGridDrawer.

An instruction like the following (in the observer code) should fix the=20
problem.

         LayerMultiObjectGridDrawer s =3D new=20
LayerMultiObjectGridDrawer("Bugs", (MultiObjGrid) model.world);


Cheers,
Michele
