Re: Sharing variables.

[Eric Werk]

Hi Fabio,

You have the variable you want to share in the class you want to give
write access, for eksample in Modelswarm, and then you implement a
method (in ModelSwarm) to read the variable. Here is an eksample:

@interface ModelSwarm: Swarm
{
   int  shared;
}
- (int) getShared;
@end;

@implementation ModelSwarm
- (int) getShared
{
   return shared
}
@end;

Then you let all your Agents have a reference to the ModelSwarm, that
you have to initialize when you create the Agent objects

@interface Agent: Swarm
{
   id modelSwarm;
}
- initModel: aModelSwarm;

and then you can read the shared variable with 
[modelSwarm getShared];
