Athan's Q3F Beta2 HUD Editting TUTORIAL - Text from CVARS

Introduction

This document aims to inform you of how you may cause the value of a cvar to appear as text in the HUD. This is useful for several kinds of scripts. Think of a display for what you will disguise to as an agent when you do so, or how many seconds a H.E Charge will be when you lay it.

HowTo

This is actually very simple, you just make use of the cvar keyword in an itemDef. The format is as in:

    cvar "<cvarname>"
   

An Example

The easiest way to really show you how this works is to show you what I have in my own HUD for the Agent class:

  menuDef {
    name "agent_scripting"
    fullscreen MENU_FALSE
    rect 0 405 146 16
    visible MENU_TRUE
    ownerDrawFlag CG_SHOW_PLAYER_IS_AGENT
    ownerDrawFlag CG_SHOW_NO_SCOREBOARD

    itemDef { 
      visible MENU_TRUE
      rect 4 0 70 16
      decoration
      textscale .27
      forecolor 1 1 1 .6
      textaligny 13
      cvar "disguiseskin"
    }

    itemDef {
      visible MENU_TRUE
      rect 97 0 5 16
      decoration
      textscale .27
      forecolor 1 1 1 .6
      textaligny 13 
      text "|"
    }

    itemDef {
      visible MENU_TRUE
      rect 102 0 70 16
      decoration
      textscale .27
      forecolor 1 1 1 .6
      textaligny 13 
      cvar "disguisecolour"
    }

    itemDef {
      visible MENU_TRUE
      rect 0 0 146 16
      decoration
      background "ui/gfx/hud/fill_center_grey.tga"
      style WINDOW_STYLE_SHADER
    }
  }
