The alternate HUD replaces the default fullscreen HUD. It features counters for all ammunition type, icons for available weapons, and counters for items picked up, secrets found, and monsters killed. The alternative HUD menu provides an user-friendly way of altering the following console variables:
The following are the values at which the color of the counter changes. For example, if hud_armor_green is 100, the armor counter is green at 100 and below.
hud_armor_green=int hud_armor_yellow=int hud_armor_red=int hud_health_green=int hud_health_yellow=int hud_health_red=int hud_ammo_yellow=int hud_ammo_red=int
hud_showitems=bool (items picked up compared to total count) hud_showmonsters=bool (monsters killed compared to total count) hud_showscore=bool (score earned so far) hud_showsecrets=bool (secrets found compared to total count) hud_showstats=bool (stamina and accuracy, usually only relevant for Strife)
The following determines if the alternate HUD is used at all.
