Tamearia Teleport Effect

This is the teleporter class for Tamearia. Instead of just suddenly teleporting the player, it has a cartoonish collapsing/expanding circle effect.

First, the teleporter itself:

class FadeOutTeleporter extends TameariaObject
    placeable;

var() edfindable FadeOutTeleporter Destination;
var Pawn Shawna;

simulated function PostBeginPlay()
{
    super.PostBeginPlay(); // TAMGame is set in the superclass TameariaObject.
}

event Touch(Actor Other)
{
    if(Other == none || Destination == none)
        return;

    if(Pawn(Other) != none && !Other.IsA('Vehicle'))
    {
        TAMGame.TeleportingPlayer(self); // Tells the game to start the fade out.
        Shawna = Pawn(Other);
    }
}

function TeleportHer() // Called through the Gametype from the HUD once the screen is faded out completely.
{
    local rotator NewRot;

    Shawna.SetLocation(Destination.Location);
    NewRot = Destination.Rotation;
    NewRot.Roll = 0;
    Shawna.SetRotation(NewRot);
}

defaultproperties
{
    bCollideActors=True
    bDirectional=True
}

Next, the code in the GameType:

class TameariaGame extends GameInfo
    HideDropDown
    CacheExempt
    config(Tamearia);

var Pawn Shawna;
var FadeOutTeleporter FadeOutTeleporter;

function TeleportingPlayer(FadeOutTeleporter FOT) // When the player hits a teleporter, stop them.
{
    FadeOutTeleporter = FOT;
    bDrawTeleport = true; // Tell the HUD to start the fade.
    Shawna.GroundSpeed = 0;
}

function DoTheTeleport() // Once the HUD is faded, tell the teleporter to teleport the player.
{
    FadeOutTeleporter.TeleportHer();
}

function FinishedTeleportingPlayer() // Once the fade in is complete, allow the player to move.
{
    Shawna.GroundSpeed = Shawna.default.GroundSpeed;
}

Then, the final part of the script in the HUD:

class TameariaHUD extends HudBase
    config(TameariaUser);

var TameariaGame TAMGame;

var float TeleportPos;
var bool bDrawTeleport, bReverseTeleportDraw;

function PostBeginPlay()
{
    TAMGame = TameariaGame(Level.Game);
    Super.PostBeginPlay();
}

function DrawHUD(Canvas C)
{
    C.SetDrawColor(255,255,255,255);

    if(TAMGame.bDrawTeleport) // If the gametype is set to teleport, acknowledge it and do the fade.
    {
        bDrawTeleport = true;
        TAMGame.bDrawTeleport= false;
    }

    if(bDrawTeleport)
    {
        C.SetPos(C.SizeX*TeleportPos,C.SizeY*TeleportPos);

        // Draw the texture with the alpha'd hole cut out of it.
        C.DrawTileScaled(Material'TameariaTextures.TeleportHUDEffect',
                         (-(TeleportPos-0.5))*(C.ClipX*2/512),(-(TeleportPos-0.5))*(C.ClipY*2/512));

        // Draw borders around the alpha'd hole texture.
        if(TeleportPos >= -0.1)
        {
            C.SetPos(0,0);
            C.DrawTile(material'UCGeneric.Black',TeleportPos*C.SizeX,C.SizeY,0,0,0,0);
            C.SetPos(0,0);
            C.DrawTile(material'UCGeneric.Black',C.SizeX,TeleportPos*C.SizeY,0,0,0,0);
            C.SetPos((TeleportPos*C.SizeX)+(-(TeleportPos-0.5))*(C.SizeX*2),0);
            C.DrawTile(material'UCGeneric.Black',C.SizeX*TeleportPos,C.SizeY,0,0,0,0);
            C.SetPos(0,C.SizeY-(C.SizeY*TeleportPos));
            C.DrawTile(material'UCGeneric.Black',C.SizeX,C.SizeY*TeleportPos,0,0,0,0);
        }
    }
}

function tick(float DeltaTime)
{
    if(bDrawTeleport)
    {
        if(!bReverseTeleportDraw)
            TeleportPos += DeltaTime; // Circle collapsing.
        else
            TeleportPos -= DeltaTime; // Circle expanding.
        if(TeleportPos > 0.5) // If the circle is collapsed, tell the gametype to teleport the player, and expand the circle.
        {
            bReverseTeleportDraw = true;
            TAMGame.DoTheTeleport();
        }
        if(bReverseTeleportDraw && TeleportPos < 0.25) // Let the player move a bit before the circle is done expanding.
            TAMGame.FinishedTeleportingPlayer();
        if(TeleportPos < -0.5) // Reset everything once the teleport is finished.
        {
            TeleportPos = -0.5;
            bReverseTeleportDraw = False;
            bDrawTeleport = false;
        }
    }
}
