Enable / disable showing of HUD. Defines visibility of weapon crosshair and any informational tags that appear when pointing the weapon at an object as well as availability of the default action menu. Unfortunately, it also hides icons drawn with drawIcon3D.
Note
Arma 3:Since Arma 3 v1.50 there is a Description.ext's showHUD[] array param that is identical in format to the extended showHUD command.
When present, it will disable showHUD command entirely, allowing mission makers to permanently alter visibility of some HUD elements. Since Arma 3 v2.04 it is possible to force drawing of drawIcon3D icons when HUD is hidden.
The icons will also show when custom camera is created and the view is switched to it via switchCamera or cameraEffect provided cameraEffectEnableHUD is enabled.
scriptedHUD: Boolean - show scripted HUD such as weapon crosshair, action menu and overlays created with cutRsc and titleRsc. Same as showHUD's first syntax
info: Boolean - (Optional, default true) show vehicle, soldier and weapon info
radar: Boolean - (Optional, default true) show vehicle radar
compass: Boolean - (Optional, default true) show vehicle compass
direction: Boolean - (Optional, default true) show tank direction indicator. Not present in vanilla Arma 3
menu: Boolean - (Optional, default true) show commanding menu (HC related menus)
group: Boolean - (Optional, default true) show group info bar (Squad leader info bar)
cursors: Boolean - (Optional, default true) show HUD weapon cursors (connected with scripted HUD)
The "cursors" parameter controls visibility of the action menu as well as weapon cursors.
However if 1st param "hud" hides and disables action menu, param "cursors" only hides it. So you get invisible action menu that is fully operational.
inGameUISetEventHandler will still fire on interaction, giving the information about selected item on the action menu even if you cannot see it.
Unfortunately it also hides icons drawn with drawIcon3D.
