[Swarm-Support] sending messages with parameters in ModelSwarm

[Eliezer Gurarie]

Dear List, 

I am a new Swarm user with a quick tactical programming question:  Can I
send a message in my Actionlist that depends on a parameter?

In my Action list I would like to perform a "rearrangement" of a Discrete2D
object "preyspace" - based on a paramater "preyProb" like so:

[modelActions createActionTo: preyspace       message: M(rearrange: preyProb)];

where "rearrange" is a standard method that takes a float "p":
- rearrange: (float)p

the compiler responds with:   ModelSwarm:133: parse error before before:
")" 

Does Swarm just inherently forbid passing methods with parameters in the
ActionList?  Do I have to define the rearrange somewhere earlier (though
it feels like this is the most natural place to tell it to do the rearrange?)

thanks, 
elie
