There generally isn’t better documentation for writing extensions than
just the Extensions API wiki page you linked or the source code itself.
In this case, you’re trying to do the very thing that an existing
NetLogo primitive does, so you can get the answer from the primitive’s
source code. The code for getting a breed variable can be found here
<https://github.com/NetLogo/NetLogo/blob/5.x/src/main/org/nlogo/prim/_breedvariableof.java#L45>.

Hello,
I have been searching and cannot find a tutorial that explains basic extension
API.
I have seen: https://github.com/NetLogo/NetLogo/wiki/Extensions-API and
http://ccl.northwestern.edu/netlogo/docs/scaladoc/ (though this is scale...I
would think that there would be explanations of the functions).
Is there better resources?
I would like to know how to extract the value of a specific agent's variable.
The getVariable function requires a number(the index of the variable in the
variables array). I need to know how to obtain the index of the variable:
AgentSet agents = ...
Agent agent = ...
int someIntValue =
Integer.valueOf(agent.getVariables(agent.world().breedsOwnIndex(agents,
"some-variable")));
This seems too complicated for such a simple task.
Thank you
-Matt
