Displaying Custom Debug Info

Displaying debug info from your custom classes is very easy inside of UDK. You'll need to implement a custom HUD to help decide what classes will show their debug info on screen.

You'll also have to implement some custom drawing inside of the objects that you want to display. This is made easy with the 'Canvas' class from the engine. You can find lots of examples within UDK of custom DisplayDebug methods so I won't talk about all of the drawing options available.

Once you've got this, you can type 'showdebug turret' in-game on the console (use ~ to bring it up) and you'll see your custom debug display. Of course, you can implement other tags other than 'turret'. You just need to handle it inside of your custom HUD code (shown below).

class MU_AutoTurret extends Pawn;

simulated function DisplayDebug(HUD HUD, out float out_YL, out float out_YPos)
{
    local string T;
    local Canvas Canvas;

    Canvas = HUD.Canvas;
 
    out_YPos += out_YL;

    Canvas.SetPos(4, out_YPos);
    Canvas.SetDrawColor(255,0,0);

    T = "Turret [" $ GetDebugName() $ "]";
    Canvas.DrawText(T, FALSE);
    out_YPos += out_YL;
    Canvas.SetPos(4, out_YPos);

    Canvas.SetDrawColor(255,255,255);

    Canvas.DrawText("Location:" @ Location @ "Rotation:" @ Rotation, FALSE);
    out_YPos += out_YL;
    Canvas.SetPos(4,out_YPos);


    Canvas.DrawColor.B = 255;
    Canvas.DrawText(" STATE:" @ GetStateName(), FALSE);
    out_YPos += out_YL;
    Canvas.SetPos(4,out_YPos);
}

class UDNHud extends HUD;

function ShowDebugInfo(out float out_YL, out float out_YPos)
{
    local MU_AutoTurret Turret;
 
    if( ShouldDisplayDebug( 'Turret' ) )
    {
        foreach WorldInfo.AllPawns( class'MU_AutoTurret', Turret )
        {
            Turret.DisplayDebug( self, out_YL, out_YPos );
        }
    }
    else
    {
        super.ShowDebugInfo( out_YL, out_YPos );
    }
}

class UDNGame extends GameInfo;
