Ok, I want that all objects in a specific group are affected by a certain function, but I am in doubt about the exact syntax I should use.

Should it be something like:

for actor in MovableMan.Actors and actor in MovableMan.GroupName do

I am rather confused, as I read the lua documentation and found very little reference to group functions. Any help would be appreciated. Thanks in advance.

Not sure which GroupName you're referring to, but your syntax is a little off.

will do something for all actors.

for whatever GroupName you have in mind,
should suffice, as long as the group is in fact in MovableMan.

I think I didn't express myself correctly.
What I mean is that, in the .ini file, I give an actor an AddToGroup = XYZ variable. Then, in the .lua file, I want the game to iterate through all the objects in group = XYZ. The problem is that XYZ is not a predefined group in MovableMan, but a custom group. So, any ideas?

actor:IsInGroup("XYZ") returns true if it is in group XYZ.
So, if everything in the group is actors, the code would go like so:

Or, if you wanted to cycle through every type of object (including particles and weapons):

This is of course assuming the code changes according to object type. Otherwise, you'd just declare a function and call it where <code> would normally be.

Yes! It works!
Thanks!

I've gotta tell you, it's fun using lua to stop missiles in mid-air and send them back to the poor soldier who shot them...
