How can I make an AEmitter have the RotAngle of where the parent actor is aiming?
If I set (considering I already did the code for who is the parent) self.RotAngle = self.parent.RotAngle would work?

You'd want something like this instead since aiming angle has its own function.

Code:
self.<Emitter>.RotAngle = self.<Actor>:GetAimAngle(true)


or if you always want the guns angle just get the gun's angle itself.

If you get the actor's Rotational Angle then your getting the angle his torso is. I believe GetAimAngle gets the angle of the head or where your cursor is aiming in respect of the selected actor.

Wait, so it would be better to get the gun's aim angle??

Code:
function Create(self)
    local curdist = 50;
    for actors in MovableMan.Actors do
   local avgx = actors.Pos.X - self.Pos.X;
   local avgy = actors.Pos.Y - self.Pos.Y;
   local dist = math.sqrt(avgx ^ 2 + avgy ^ 2);
   if dist < curdist then
       curdist = dist;
       self.parent = actors;
   end
    end

end

function Update(self)
 self.RotAngle = self.parent.RotAngle
 end

This is my code so far. I tried to get the gun's angle, but I don't know how to do that.

No. Aim angle only applies to things that can see. (Actors, AHumans and ACrabs)

So it would be the guns RotAngle?

The actor's aim angle.

GetAimAngle only works on Actors, just like Roast Veg said. To get a non-actor's Rotational Angle, use .RotAngle like you are now.

Just use the aim angle method I gave you.

Replace the
Code:
self.RotAngle = self.parent.RotAngle

with
Code:
self.RotAngle = self.parent:GetAimAngle(true)

and it should work.
