Finding out which way the player view is facing (not direction)

[rejenorst 18]

I am trying to find a way to tell which way the player's camera view is facing. I don't want to use getdir as players will often use mouselook/freelook.

you can use cursorTarget, but it will only work sometimes, ie only when looking at a object.

you can run a loop and add the direction to the cursor target from player, to get latest "valid direction" but this will be not 100%.

also this is a theory, but see if you can atach something to the head of the player or if you can get the glasses object on player then getDir from that.

but i believe this is impossible atm in Arma2.

in Arma3 this will be possible as we can change gear ie helmets and then get the dir from that, (my theory)

Yeah I had thought of attachto with a gamelogic to the players head but I yeah I think it's impossible to access the infantry model heads as an object.

I'll look into cursor target.

Also I found this:

Dunno if this command might come in handy.

There's a community addon which allows for functions related to player head dir.

EDIT:

Have found the following topic which would be my best lead at the moment:

I'm just guessing here but if the camera space is:

x is +right

y is +up

z is +away

or, that you some how can find the away camera axis then you can do this (let's assume the z axis is away):

_pointAhead = positionCameraToWorld [0,0,5];
_playerPos = getPos player;
_xDiff = (_pointAhead select 0) - (_playerPos select 0);
_yDiff = (_pointAhead select 1) - (_playerPos select 1);

Then based _xDiff and _yDiff you can find the compass direction.

this is tested and working, changed celerys code but he got me on right track.

_null = [] spawn {
while {true} do {
	[b]_pos1 = screenToWorld [0.5,0.5];
	_pos2 = getPos player;
	_dirWatching = ((((_pos1 select 0) - (_pos2 select 0)) atan2 ((_pos1 select 1) - (_pos2 select 1))) + 360) % 360;[/b]
	hint format["looking in %1 direction",(round _dirWatching)];
	sleep 1;
};
};

palced in a trigger on act field for testing, the relevant code is highlighted.

Awesome will test that out Demonized
