AltHud is a class used by GZDoom to draw its alternative HUD (hud_althud CVAR must be set to true). New alternative HUDs can be created based on this class. The main difference between AltHUD and BaseStatusBar is that AltHUD draws using absolute screen coordinates and doesn't utilize the same scaling as BaseStatusBar. It also doesn't support aspect scaling (the value of the hud_aspectscale CVAR is ignored). AltHUD mainly utilizes the Screen struct functions to perform drawing.
Using this class is not recommended if the author wants to make a HUD that supports scaling.
Note, to see your HUD in the game, it MUST be added via the GameInfo block of the MAPINFO lump as follows:
GameInfo
{
StatusBarClass = "MyCustomHUD" //replaces the base HUD
AltHUDClass = "MyCustomAltHUD" //replaces the alternative HUD
}
See ZScript HUDs for details.

- Draws a number with a fixed width for all digits
- void AddAmmoToList(readonly<Weapon> weapdef)
- Adds ammo to the list of ammo classes to draw.
- int, int GetAmmoTextLengths(PlayerInfo CPlayer)
- Checks the ammo types carried by the player and returns the longest length of the strings representing the current amount of ammo and the maximum amount of ammo (to make sure the block displaying all ammo fits where it should).
