Markers on targets

[Martin Vole]

So, I've been exploring multiple options for this but the main idea is that any potential targets nearby meeting certain criteria will be marked with an icon from the perspective of the player. I got the criteria part down, and I'm using RadiusActors. The actual problem is drawing the icons.

Never seen many examples of this in games, and the one that does similar (Klingon Honor Guard) has a rather awkward implementation.

Any ideas?

This is an old video but the code works really well. Other HUD overlays tend to slide around when you view from a high/low Z angle but this stays very stuck to the tagged actor:


If you want the code let me know. It's pretty easy to add it to your mod and replace the health script with an icon or whatever. The original code was wormbo's mod for team icons (used with permission). I've seen a lot of attempts at icons attached to actors via the HUD but this method is by far the most solid.

I hope it's what you need.

This code is easily untouched and older than a decade, but gets the job done. Note this is meant to display other (real) players locations in a coop server.

this is a section from an UnrealHUD subclass

Code: Select all

simulated function PostRender( canvas Canvas )
{
      Super.PostRender(Canvas);
      if ( PlayerPawn(Owner)!=None && !PlayerPawn(Owner).bShowMenu && !PlayerPawn(Owner).bShowScores )
            drawindicator(canvas);
}
function drawindicator(canvas canvas)
{
      local Pawn P;
      local float X, Y,XL,YL;
      local bool bOnScreen;
      local vector worldPosition;
      local Actor A;
      local pawn pawnowner;

      Canvas.Font = Font'SmallFont';
      Canvas.ClipX+=500;
      Canvas.DrawColor.R = 255;
      Canvas.DrawColor.B = 255;
      Canvas.DrawColor.G = 255;
      Canvas.Style = 3;
      ForEach VisibleCollidingActors(class'Pawn',P,5000,ViewPos)
      {
            if( P==Owner || P.PlayerReplicationInfo==None ) Continue;
            worldPosition = P.Location;
            worldPosition.Z += P.CollisionHeight;
            bOnScreen = WorldToScreen(worldPosition, Pawn(Owner),ViewPos,ViewRot, Canvas.ClipX-500, Canvas.ClipY, X, Y);
            if (bOnScreen && X > 0 && X < (Canvas.ClipX-500) && Y > 0 && Y < Canvas.ClipY)
            {
                  Canvas.DrawColor.B = 255;
                  Canvas.DrawColor.R = 255;
                  Canvas.DrawColor.G = 255;
                  Canvas.SetPos(X - 32, Y - 32);
                  Canvas.DrawIcon(Texture'Indicator',0.5);
                  if( P.PlayerReplicationInfo!=None && P.PlayerReplicationInfo.IsA('kPlayerReplicationInfo') )
                  {
                        Canvas.Font = Font'medFont';
                        if( kPlayerReplicationInfo(P.PlayerReplicationInfo).bIsAdmin )
                              Canvas.DrawColor = kPlayerReplicationInfo(P.PlayerReplicationInfo).AdminColor;
                        else
                        {
                              Canvas.DrawColor.B = 200;
                              Canvas.DrawColor.R = 200;
                        }
                        Canvas.TextSize(P.PlayerReplicationInfo.PlayerName,XL,YL);
                        Canvas.SetPos(X - XL/2, Y - 32 - YL);
                        Canvas.DrawText(P.PlayerReplicationInfo.PlayerName,False);
                  }
            }
      }
      Canvas.DrawColor.B = 255;
      Canvas.DrawColor.R = 255;
      Canvas.DrawColor.G = 255;
      Canvas.ClipX-=500;
}
simulated static function bool WorldToScreen(Vector WorldLocation, Pawn ThePlayer, vector EyePos, rotator ScreenRot,
     float ScreenWidth, float ScreenHeight, out float X, out float Y)
{
   local vector RelativeToPlayer;
   local float Scale;

   RelativeToPlayer = (WorldLocation - EyePos)

Canvas.ClipX+=500; is probably used to prevent word wrapping.

Using 227 here, but I do got a bit of something simple working now:

Code: Select all

simulated event PostRender(Canvas C)
{
      local Pawn P;
      local bool bOnScreen;
      local vector worldPosition;
      local vector HudLoc;
      local float Dummy;
      
      C.Style = ERenderStyle.STY_Translucent;
      
      ForEach VisibleCollidingActors(class'Pawn',P,2000,, true)
      {
            worldPosition = P.Location;
            HudLoc = C.WorldToScreen(worldPosition,Dummy);
            if( HudLoc.Z>0 )
            {
            C.SetPos(HudLoc.X - 8, HudLoc.Y - 16);
            C.DrawIcon(Texture'hudteeth',1);
            }
      }
      
}

This is before the target scrutinizing code.
