Screen size

screen_size

Holds the player's screensize - starts at 0 for no HUD and then increments by 4 for each size of screen, up to 64. A value of 4 means the player has just the Health, Ammo and Inventory visible, and 8 & up means they have the full status bar up.

Example:

// Remove the old HUD
setuserdef[THISACTOR].screen_size 0
