I had a great idea concerning robots in a certain field being Uncontrollable and unable to move, I'm assuming that Inactive status would Achieve part of this (Unable to move), but I don't know how to set it.

So, how do I set the Status of an actor?

for actor in MovableMan.Actors do
actor.Status = 2;
end

Should work.

Hmm, Either the Inactive setting does nothing or the code isn't working, I'm voting on the former.
Is there any other way to completely incapacitate an actor?

Well try a different status check to see if that's the problem.

Huh, I tried the Dead status and nothing happened, so it must be the code.

Is it returning an error? If not, it's not the code.

It could just be that the game doesn't care what the status is set to via Lua.

Ah, I don't see any Error in the console, So you are right.

You could pin him.
I believe you can just do

But then they can still fire.

For my EMP grenade, I just used SetControllerMode(Controller.CIM_DISABLED), an Actor function. Just keep calling that on actors in the Update code for as long as you want. As soon as you stop calling it, they'll go back to normal, so it's pretty simple to use.

Tip:
CIM_NETWORK works much better than CIM_DISABLED, as for some reason disabled units still turn to the direction they get shot in.

Well, I also made it so they flip out and constantly look in random directions, so that's not quite so noticeable.

Never tried the network setting though.
