random starting poi

[Suhad Faisal]

Hello 

I have a problem in my model that is 

each time the starting point of my agent is drawn randomly,  even when I made several trials to initiate it, so any help or comment please ! 

the model is attached with related files 

thanks in advance 

cheers

If you read the documentation, you will find out that all agents have an attribute called « location ». This is the one to initialize if you want to set the position of agents in the environment. The one of the only instance of aliasrep you create is *never* initialized.

More generally, in your case, you seem to mix a number of different things when creating your « tower » agents, for example. Why do you have posxtower, posytower as a global attribute ? Why do you initialize the « global » location rather than the location of these agents ? Why do you have so many useless attributes in your species, which are never used nor initialized ?

My guess, by reading your code, is that you still dont have understood the difference between the « global agent » (the « world ») and the other agents (instances of species) — and that you probably dont try too hard to read the documentation: for instance, if your « towers » are present in a shapefile, and if you create agents from them, their shape *and* location will be correctly initialized without further effort, so you dont need all this stuff (posxtower, posy tower, whatever).

Have you tried to follow the different tutorials ? That would help.

thank you Alexis for your reply and comments 

but indeed I defined these attributes for future extention in the development of my model, its not for the instant stage, and about the initialization I have several trials as a scratch code , I can't send all of them avoiding wasting others time. 

thank you  for reply and comments 

cheers
