Projectile Startup on Network

[Saishy]

I have a magic missile spell that extends from the weapon system, it works correctly in single player but in multiplayer the missiles always chase the (0,0,0) of the map on clients.

My guess is that since the missiles are able to chase, they are not getting the target's location on the clients.

class MMSkillMagicMissile extends MMSkill;

	const AdjustPoint = 100;
	const GatherDist = 50; //The distance from the offset point the missile needs to get before chasing the target
	const SquareAngle = 16384;

	var Vector PointTarget[2]; //If there is no target, define two points to follow
	var float PosOffset; //A little random distance from the target
	//debug
	//var(Debug) bool bDebug; // Used to toggle debug logging

simulated function CustomFire()
{
	//The variables for the tracing
	local Vector End, PawnEyePosition, PawnEyeHitLocation, PawnEyeHitNormal, CameraHitLocation, CameraHitNormal;
	local Rotator CameraRotation;
	local TargetableObject CameraHitObject, PawnEyeHitObject;
	local Actor SeekTarget;

	//The variables for the missile position
	local Vector Offset, Pos[5], Loc, Tar[2], CamLoc;
	local Rotator Facing, ViewRot, Temp;
	local float CRadius, CHeight;
	local int i;
	local MMMagicMissile Missile;
	
	if ( Owner.Role == ROLE_Authority )
	{
		Loc = Owner.Location;
		CamLoc = MMGamePawn(Owner).GetPawnViewLocation();
		MMGamePawn(Owner).GetPawnEyesViewPoint(PawnEyePosition, CameraRotation);
		End = CamLoc + (Vector(CameraRotation) * WeaponRange);

		CameraHitObject = TargetableObject(Owner.Trace(CameraHitLocation, CameraHitNormal, End, CamLoc, true, Vect(3,3,3)));

		//Owner.DrawDebugLine(CamLoc, End, 255, 0, 0, true);
		if (CameraHitObject != none)
		{
			PawnEyeHitObject = TargetableObject(Owner.Trace(PawnEyeHitLocation, PawnEyeHitNormal, CameraHitLocation, PawnEyeHitLocation, true, Vect(3,3,3)));

			if (IsZero(PawnEyeHitLocation) || CameraHitObject == PawnEyeHitObject)
			{
				SeekTarget = CameraHitObject;
				//`Log(CameraHitObject @ PawnEyeHitObject @ SeekTarget);
			}
		}

		Facing = Pawn(Owner).GetViewRotation();
		Facing.Pitch = 0;
		//Facing = Owner.newRotation;
		CRadius = Pawn(Owner).GetCollisionRadius();
		CHeight = Pawn(Owner).GetCollisionHeight();
		Offset = Loc - (Vector(Facing) * (CRadius / 1.5));
		ViewRot = Pawn(Owner).GetViewRotation();
		Tar[0] = CamLoc + (Vector(ViewRot) * AdjustPoint);
		Tar[1] = CamLoc + (Vector(ViewRot) * 2500);

		Temp = Facing;
		Temp.Yaw += SquareAngle;
		Pos[0] = Offset + (Vector(Temp) * CRadius);
		Temp = Facing;
		Temp.Yaw -= SquareAngle;
		Pos[1] = Offset + (Vector(Temp) * CRadius);
		Pos[2] = Pos[0] + (Vect(0, 0, 1) * (CHeight / 1.5));
		Pos[3] = Pos[1] + (Vect(0, 0, 1) * (CHeight / 1.5));
		Pos[4] = Offset + (Vect(0, 0, 1) * CHeight);
		Offset = Offset - (Vector(Facing) * (CRadius / 2)); //So the missiles do a better turn

		for(i=0; i<5; i++)
		{
			Missile = Owner.Spawn(class'MMMagicMissile', Owner, , Pos[i], Rotator(Pos[i] - Offset), , true);
			if( Missile != None && !Missile.bDeleteMe )
			{
				//Missile.InitialRelease = Loc;
				Missile.GatherDist = GatherDist;
				Missile.AdjustPoint = AdjustPoint;
				//Missile.PointTarget[0] = Tar[0];// + (VRand() * PosOffset);
				Missile.PointTarget = Tar[1];// + (VRand() * (PosOffset / 2));
				Missile.VectorTarget = Tar[0];
				Missile.SetTarget(SeekTarget, true);
				//Missile.Init(Pos[i] - Offset);
				`Log("Magic Missile incomming");
			}
		}

			Missile.bDebug = true;
			Owner.DrawDebugSphere(Tar[0], 25, 8, 0, 0, 255, true);

But I don't know how can I replicate the VectorTarget, PointTarget, GatherDist and AdjustPoint, I thought of putting on the PostBeginPlay but as soon as the missiles are spawned the function is called instead of waiting for customfire() to finish. (And I thought unreal was single-threaded).

How can I replicate those variables if as soon as I spawn the missile it is cut from the network?

Thank you very much.
