Displaying data onscreen, score for example.

[danydrunk]

Iven been reading the info at udn and wikipedia, but I cant figure out what part actually prints the info onscreen. For example in the myfirst example classes theres one called: ExampleHud.uc

This .uc file has:

class ExampleHUD extends HUD;

var PlayerController PlayerOwner;
var Material HUDScoreBox;



simulated function PostBeginPlay()
{
Super.PostBeginPlay();
PlayerOwner = PlayerController(Owner);
}


function DrawHUD(canvas Canvas)
{
local Pawn PawnOwner;
local PlayerReplicationInfo PawnOwnerPRI;
local int FontSize;
local float HUDScoreScaleX, HUDScoreScaleY;
local float HUDScorePosX, HUDScorePosY;
local int Score;
local string ScoreString;
local float XL,YL;

// Get PlayerOwner
if (PlayerOwner.ViewTarget == PlayerOwner)
{
PawnOwner = PlayerOwner.Pawn;
}
else if (PlayerOwner.ViewTarget.IsA('Pawn') && Pawn(PlayerOwner.ViewTarget).Controller != None)
{
PawnOwner = Pawn(PlayerOwner.ViewTarget);
}
else if ( PlayerOwner.Pawn != None )
{
PawnOwner = PlayerOwner.Pawn;
}
else
{
PawnOwner = None;
}

// Get PlayerReplication
if ((PawnOwner != None) && (PawnOwner.Controller != None))
PawnOwnerPRI = PawnOwner.PlayerReplicationInfo;
else
PawnOwnerPRI = PlayerOwner.PlayerReplicationInfo;

//Get Font Size - (larger numbers are smaller fonts)
if ( Canvas.ClipX <= 640 )
FontSize=2;
else if ( Canvas.ClipX <= 800 )
FontSize=3;
else if ( Canvas.ClipX <= 1024 )
FontSize=2;
else if ( Canvas.ClipX <= 1280 )
FontSize=1;
else if ( Canvas.ClipX <= 1600 )
FontSize=0;
else
FontSize=0;
Canvas.Font = LoadFontStatic(FontSize);


// Draw Hud


Right now if I run it, theres a score at the right side of the screen that increases when I do the DoDance thing. What If I want to print a second score thing on the screen ? that increases when I do the fly for example ? Of all the code presented which part is actually displaying the score to the screen? Im new to this and I just need to get started, this will help me a lot thanks.

This fragment you posted doesn't draw anything.

I suppose you're talking about this: http://udn.epicgames.com/Two/MyFirstHUD#My_First_HUD

the following bit of code just prepares the variables required to to script to work properly (where from the score should be taken, etc)

// Get PlayerOwner
if (PlayerOwner.ViewTarget == PlayerOwner)
{
PawnOwner = PlayerOwner.Pawn;
}
else if (PlayerOwner.ViewTarget.IsA('Pawn') && Pawn(PlayerOwner.ViewTarget).Controller != None)
{
PawnOwner = Pawn(PlayerOwner.ViewTarget);
}
else if ( PlayerOwner.Pawn != None )
{
PawnOwner = PlayerOwner.Pawn;
}
else
{
PawnOwner = None;
}

// Get PlayerReplication
if ((PawnOwner != None) && (PawnOwner.Controller != None))
PawnOwnerPRI = PawnOwner.PlayerReplicationInfo;
else
PawnOwnerPRI = PlayerOwner.PlayerReplicationInfo;

The following fragment just selects the font fitting for the current screen resolution

//Get Font Size - (larger numbers are smaller fonts)
if ( Canvas.ClipX <= 640 )
FontSize=2;
else if ( Canvas.ClipX <= 800 )
FontSize=3;
else if ( Canvas.ClipX <= 1024 )
FontSize=2;
else if ( Canvas.ClipX <= 1280 )
FontSize=1;
else if ( Canvas.ClipX <= 1600 )
FontSize=0;
else
FontSize=0;
Canvas.Font = LoadFontStatic(FontSize);

But you left out the bit that is mentioned later:

function DrawHUD(canvas Canvas)
{
   ...

   // Draw Hud

   Canvas.SetDrawColor(255,255,255);
   HUDScoreScaleX = Canvas.ClipX/800;
   HUDScoreScaleY = Canvas.ClipY/600;
   HUDScorePosX = Canvas.ClipX - 256*HUDScoreScaleX;
   HUDScorePosY = Canvas.ClipY - 128*HUDScoreScaleY;
   Canvas.SetPos(HUDScorePosX, HUDScorePosY);
   Canvas.DrawTileScaled(HUDScoreBox, HUDScoreScaleX, HUDScoreScaleY);

   Canvas.SetDrawColor(230,240,240);
   Score = PawnOwnerPRI.Score;
   ScoreString = ""$Score;
   Canvas.StrLen(ScoreString,XL,YL);
   Canvas.SetPos(HUDScorePosX + 235*HUDScoreScaleX - XL, HUDScorePosY + 70*HUDScoreScaleY);
   Canvas.DrawText(Score);
}

That's the function that actually does the drawing.

You need to have al three bits in your function. Also the defaultproperties bit should be in defaultpropertis of you class

Yes I was talking about that Hud. What I havent been able to figure out is how to make the game display more than one score in on the screen. For example right now every time I press the key "G" my score increases by 1 (or more if I specify so). Lets say I want to put another score that decreases everytime I press F for example. How would I get to print two scores in the screen at the same time. So far all my atempts to make it have failed. Thanks
