[solved] Attach Actor to Actor

[LannFyre]

I need to attach a directional actor to another directional actor.  SpriteActor (used for animations) needs to be attached to my custom playerpawn (RPG_LionPlatformer), facing the same direction and being in the same location as the playerpawn.  How can I do this?

If this is solved, I may have a new progress video coming out to show off sprites working properly.  I have a parser for sprites mostly working, animation and animation managers work properly, and I now need an actor (SpriteActor) that can be used in order to "play" animations on that isn't a playerpawn to avoid dealing with figuring out why animation code either isn't being called or works improperly in player state code.  I also have a sprite sheet that acts as a library for textures stored to be played sequentially.

- Set the actor's Physics to PHYS_Trailer;
- Set the actor's owner to your Playerpawn;
- Set bTrailerSameRotation of the actor to True.

[.:..:]

It depends, relative to what?

If same rotation and location as playerpawn, you can use PHYS_Trailer.

If same rotation but a location with an offset from playerpawn, then a script like this:

Code: Select all

function Tick( float Delta )
{
      SetLocation(Owner.Location + vect(0,0,10) + (vect(10,10,0) >> Owner.Rotation));
}

If a relative location and rotation:

Code: Select all

function Tick( float Delta )
{
      local Coords C;
      
      C = GetUnitCoords();
      C *= rot(16000,0,0);
      C *= Owner.Rotation;
      SetRotation(OrthoRotation(C.XAxis,C.YAxis,C.ZAxis));
      SetLocation(Owner.Location + vect(0,0,10) + (vect(10,10,0) >> Owner.Rotation));
}

How do I set an actor's owner? I've done the other two steps so far. Also here is a test video before I got your replies, I went with a setlocation() setrotation() setup through tick and found some... interesting things about sprites.

An interesting side note is that sprites only have one polygon (from my understanding and reading) which is the only point affected by light sources, so your sprite could be sitting almost half in dark and half in light, and would only change to a darkened or brightened sprite based on where that poly is.

You can use Actor.SetOwner() or even better, use spawn owner parameter:
Spawn(class'MyActor',)
i.e from playerpawn: Spawn(class'MyActor',self);

Here is what I went with:

Code: Select all

event PostBeginPlay()
{
      local bool bSActorFound;

      bSActorFound=false;
      if ( myActor == none ) {
            ForEach AllActors (class'xActor', myActor) {
                  if (myActor.Owner == none && myActor.AttachActor == none ) {
                        myActor.SetOwner(self);
                        myActor.AttachActor = self;
                        bSActorFound = true;
                        break;
                  }
            }
            if (bSActorFound == false) {
                  myActor= Spawn(class'myActor',self); // owner = self
                  myActor.AttachActor = self;
            }
      }
      
      super.PostBeginPlay();
}

Code: Select all

state Active
{
      event Tick( float DeltaTime )
      {
            SetRotation( AttachActor.Rotation );
            [...]
      }
}
