State label problem

[Cozmo]

So I learned about states today, just so I could use one latent function (MoveTo()) for NPC movement in MP. There're probably ways of doing this already, but I thought coding my own path nodes would be quicker / easier and would probably be less trouble on MP too, seeing as I can't find anything on it anywhere.

I'm pretty sure I understand states now, but it won't let me compile this:

Code: Select all

State Patrolling
{
   function GetMoving()
   {
      foreach AllActors(class'CozPath',cpa)
      {
         if(cpa.PathName == PathName)
         {
            if(cpa.PathPoint == PathPoint)
            {
               goto 'LabelMove';
            }
         }
      }
   }

                //Long irrelevant stuff here

   LabelMove:

      if(cpa != none)
      {
         MoveToward(cpa);
      }
}

for this reason:

Error, Label 'LabelMove' not found in this block of code.

Was I wrong assuming that I can just declare new labels? Or have I done something really silly?

forgot { one line after "LabelMove:"? :p

I am not THAT much familiar with states but I'm pretty sure that you can just jump to labels within a function.
The conclusion is that you cannot jump from a function somewhere into a state code.
You can call functions from state code though..
To make it work you need to restructure it.
So it looks more like..

Code: Select all

State Patrolling
{
   function GetMoving()
   {
      foreach AllActors(class'CozPath',cpa)
      {
         if(cpa.PathName == PathName)
         {
            if(cpa.PathPoint == PathPoint)
            {
               gotoState('myMoveState');
            }
         }
      }
   }
}

state myMoveState
{
 
Begin:
      if(cpa != none)
      {
         MoveToward(cpa);
      }
}

But mind that you're in another state then.
If that function GetMoving is supposed to work always, you need to make it global.. means put it outside of the state.

If you're doing MP coding.. MIND that states can be simulated but that does NOT make them auto-replicated.
Basically states on the client run independently from the states on the server.

Ah, this makes a lot more sense now. I don't think UnrealWiki mentioned this (or I am blind) / will update it.

I just tried it the way you structured it - it's compiled now; will test it later. Thanks a lot for the help Nobody!
