View source for How to display negative numbers with the digital font

In the default game, there is no minus symbol for the digital numbers.  When you try to display a negative number with the digital set, it displays the steroids icon instead of a minus symbol.  With that knowledge, in this tutorial, we will take advantage of the [[dynamicremap]] command to move the steroids icon to a different slot, and the [[DEF_Language#tilefromtexture|tilefromtexture]] to add in the new minus symbol and the steroids icon.

== Procedure ==

In GAME.CON/EDUKE.CON, put this at the top of the file:

 dynamicremap

Down in DEFS.CON where it says:

 define STEROIDS_ICON 2469

Change to:

 define STEROIDS_ICON 2459 // 2469

This will tell the game to display tile #2459 for the steroids icon, instead of #2469.  Currently, tile #2459 is empty, so we will have to re-add the steroids icon, as well as the minus symbol.

Download [http://hendricks266.duke4.net/stuff/digital_minus.zip digital_minus.zip (1.67 kb)], and extract it to your base-level mod directory.

Finally, put this at the '''bottom''' of duke3d.def.  It will add in the 8-bit art required for the steroids icon and minus symbol, as well as adding high resolution versions of the two tiles.

 undefmodel 2459
 undeftexture 2459
 
 copytile 2459 { tile 2469 }
 
 undefmodel 2469
 undeftexture 2469
 
 tilefromtexture 2469 { file "highres/8bit/2469.png" xoffset -4 yoffset -3 }
 texture 2469 { pal 0 { file "highres/screen/fonts/digital/2469.png" } }

Viola!  If you want to test it, put this at the top of GAME.CON:

 gamevar [[PLR_MORALE]] -5 0

The large HUD should display "-5" under ARMOR.
