Passing arrays to functions

Hi all,

I need to be able to pass an array to a function for some recursive calculations that I'm doing. As long as I've used Torque I never tried this before in script, and now obviously I discover that it doesn't work. I came across a resource that was supposed to explain how it can be done, but that resource is apparently broken.

I am trying hard to avoid having to write any C++ code for the prototyping of this project because I'm collaborating with somebody who does not have a TGB Pro license. It will pretty soon reach the point where it would have been more cost effective for me to just buy him a pro license and do it in C++, but I think it's still something that would be nice to know how to handle in script.

I guess theoretically I could convert the array to a space-delimited string and then parse it back to an array inside the function, but I have a feeling that would end up making it too slow for my purposes.

So does anybody know an elegant way around this?


Thanks,
Gerald

Space delimited string is one option, you can also use your own delimiter with nextToken.

Another alternative is to store the array in a dynamic field within a ScriptObject, then pass the ScriptObject to the function instead.

%someObj = new ScriptObject();
  %someObj.array[0] = "hi";
  %someObj.array[1] = "lo";

  someFunction( %someObj );

Then in someFunction you'd just access the array as %someObj.array[i]

Aha, thanks Gary. The ScriptObject method is perfect.

I just posted a TScriptArray resource here:
www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=15077

It wraps this same idea with some helper functions you might find useful.
