Hi Sean, thanks for all the help.
I'd like to be able to help, if I can, students in Dr. Axtell's classes
for example that may want some guidance getting started with Mason.
Parts of how Mason's working are still a little 'magical' to me, but
should get easier with time.
I'm modeling the CoordinationGame (from Ascape) on your Schoolyard
example. I also just got some code working from using the draw()
function from AntsForaging on Mason.
Here's what I have (this is kind of hybrid code at this point)
This code now shows a mixed number of yellow and red oval agents
(CoordinationPlayer) on a blue grid. So I think the initial beginning
is now working.
Sean - I'm not sure where I would insert your "MyPortrayal" suggestion.
Is it the same thing I'm doing here, or is there an essential
difference. I think my version may have each agent drawing/painting
themselves, your MyPortrayal version may be different?
See if this is a good structure to start from. I'd like to be able to
translate easily - and show other students how to do this - from
Ascape/Netlogo/Repast to Mason. I'd like to think that this is possible
to do.
Thanks
Randy
Here's my CoordinationGame (adapting from Ascape) so far -
FILE 1:
public class CoordinationPlayer implements Steppable
{
protected SimpleColorMap colormap = new
SimpleColorMap(0,1,Color.black,Color.white);
public Color color;
public CoordinationPlayer()
{
if ((int)(Math.random()*2) == 0)
color = Color.red;// colormap.getColor(.2);
else color = Color.yellow; //colormap.getColor(.7);
}
public Color getColor()
{
return color;
}
public void step(SimState state)
{
CoordinationPlayers students = (CoordinationPlayers) state;
ObjectGrid2D yardgrid = students.yardgrid;
}
public final void draw(Object object, Graphics2D graphics,
DrawInfo2D info)
{
THIS IS FROM ANTS FORAGING:
int x = (int)(info.draw.x - info.draw.width / 2.0);
int y = (int)(info.draw.y - info.draw.height / 2.0);
int width = (int)(info.draw.width);
int height = (int)(info.draw.height);
graphics.setColor(color);
graphics.fillOval(x,y,width, height);
}
}
FILE 2
public class CoordinationPlayers extends SimState
{
public int yardgridWidth=10;
public int yardgridHeight = 10;
public ObjectGrid2D yardgrid = new
ObjectGrid2D(yardgridWidth,yardgridHeight);
public int numStudents = 30;
public int numBuyers = 30;
double forceToSchoolMultiplier= 0.01;
double randomMultiplier = 0.1;
public Network buddies = new Network(false);
public CoordinationPlayers(long seed)
{
super(seed);
}
public void start()
{
super.start();
yardgrid.clear();
for(int i = 0; i < numStudents; i++)
{
CoordinationPlayer student = new CoordinationPlayer();
int x = random.nextInt(yardgridWidth);
int y = random.nextInt(yardgridHeight);
yardgrid.set(x,y,student);
do {
x = random.nextInt(yardgridWidth);
y = random.nextInt(yardgridHeight);
} while (yardgrid.get(x,y) != null);
schedule.scheduleRepeating(student);
}
}
public static void main(String[] args)
{
doLoop(CoordinationPlayers.class, args);
// Longer version:
/*
SimState state = new Students(System.currentTimeMillis());
state.start();
do
if (!state.schedule.step(state)) break;
while(state.schedule.getSteps() < 5000);
state.finish();

System.exit(0);
}
