Subject: problems to locate and visualize an agent in imported map

Hello Colleagues
I have problems to locate and visualize an agent into my spatial entity imported from a raster ASC format map. The tutorials only describe how to locate an agent into an “artificial” space create in Cormas, so I need help to located it in a imported map with his attribute “cover”, that I can visualize without problem on the Cormas space before programming the social entity.
I followed the following steps:
1- I create a social situated entity called “colono”
2 -In "instance" in “init” I write super init, in “initId” I write :
initId
self id: (self class CurrentId: self class CurrentId + 1)
3- in “control” I create a “step” with the following information: (following tutorial 1 and 2)
step
"The main method of the colono. It walk randomly; if it arrives on a cell in bosque, it burn it, if it arrives on a cell burn it leave strubble, if it arrives on a strubble cell, it cultivate grass”
self randomWalk.
self bosqueQuema
self quemaToRastrojo.
self rastrojoToPasto.
self perception: 4
and I create the respective methods of bosqueQuema, quemaToRastrojo….. like this:
bosqueQuema
self patch state = #bosque ifTrue: [self patch state: #quema]
4- I create a point of view of the “colono” and I assign a symbol to him.
5 -in the initial instantiation there is an accessing for theColonos and TheCells
6-In control I write:
step: t
self stepSynchronously: t.
self theColonos do: [:fm | fm step].
self updateData: t.
6-Finally in init
init
self initCells.
self initAgents.
initAgents
super initAgents.
"create the population"
self setRandomlyLocatedAgents: Colono n: 50
In the space I assigned povNum for the spatial entity and pov for the social entity. I swiched off cell delimitation. I opened simulation and I selected a method, init or initAgent, and a control, step in this case; and I did not visualize anything. Neither the map and the agents. Where is the problem?
Thank you very much for your help
Syncerely,
Manuela
