Is visible

[xxxmlgxxxt 10]

Is there any way to check if something is visible?

[MrSanchez 243]

Depends on what way something wouldn't be visible. Please elaborate.

[xxxmlgxxxt 10]

A line of sight check just checking if something is visible for your player.

Edit: i might of just found something testing it now.

Edit2: doesnt seem to be working.

Ah, the line of sight check.

I can't give you a ready to go script but you will likely find what you're looking for in any of these posts:

This should work:

_objecttocheck = myvehicleobjectormodeliwannacheck;

//You could also just use a position for a house and so on...
_position = getposATL _objecttocheck;

//returns: [] if not on screen, [1,1] lower right, [0,0] upper left
_screencoordinates = worldToScreen _position;

if ((count _screencoordinates) == 0) then {
player globalchat format ["Object: %1 not on screen!",typeOf _objecttocheck];
} else {
player globalchat format ["Object: %1 is visible on screen with the following coordinates: %2!",typeOf _objecttocheck, _screencoordinates];
};

you can use this if you want.

/*
Description: checks line of site between 2 units. will return true if 'unit1' can see 'unit2'.
By: Nimrod_Z
*/
_unit1 = _this select 0;
_unit2 = _this select 1;

NRZ_eyeDir = {
_eval = (eyeDirection _this);
_edir = (_eval select 0) atan2 (_eval select 1);
if (_edir < 0) then {_edir = 360 + _edir};
_edir
};

_canSee = false;
_inView = [position _unit1, _unit1 call NRZ_eyeDir, 120, position _unit2] call BIS_fnc_inAngleSector; 
if (_inView) then 
{
if (! terrainIntersectASL [eyePos _unit1, eyePos _unit2]) then 
{
	if (count (lineIntersectsWith [eyePos _unit1, eyePos _unit2, _unit1, _unit2]) == 0) then 
	{
		_canSee = true;
	};			
};
};
_canSee

Doesn't work in ArmA 2, the eyeDirection command was introduced in ArmA 3.
