Zone Restriction Signposts


R.Flagg on the BIS forums wanted to know how to give players a visual cue that they were leaving a zone restricted area.  The ZORA module is used to limit the area a player can leave by spawning groups to hunt them should they leave a trigger area.  Here’s a method (including a demo mission) of reminding the player they are about to enter a no-go zone.

This script uses code adapted from MH6 to create a ring of No Entry signs around a Zora trigger zone at 15m intervals. Main drawback is that since I suck at math the trigger has to be a circle. Perhaps some math wiz would be able to make this work with other shapes.

Run it from init.sqf as:

Code:
nul = [BIS_Zora_0] execVM "zoraSigns.sqf";
Code:
_zoraZone = _this select 0;
_zoraPos = getPos _zoraZone;

_sizeZone = triggerArea _zoraZone;
_angle = _sizeZone select 2;
_radius = _sizeZone select 0; // needs to be a circle with equal a and b
_distanceBetweenPosts = 15; // meters
_count = round((2 * 3.14592653589793 * _radius) / _distanceBetweenPosts);
_step = 360/_count;

for "_x" from 0 to _count do
{
	_a = (_zoraPos select 0)+(sin(_angle)*_radius);
	_b = (_zoraPos select 1)+(cos(_angle)*_radius);

	_pos = [_a,_b,_zoraPos select 2];
	_angle = _angle + _step;

	_post = "Sign_1L_Noentry_EP1" createVehicle _pos;
	_post setPos _pos;
	_relDir = [_post, _zoraZone] call BIS_fnc_DirTo;
	_post setDir _relDir - 180;
};

_mrkCrossName = format["%1CrossMarker",_zoraZone];
_mrkCross = createMarker[_mrkCrossName,_zoraPos];
_mrkCross setMarkerShape "ELLIPSE";
_mrkCross setMarkerBrush "CROSS";
_mrkCross setMarkerColor "ColorRed";
_mrkCross setMarkerSize [_radius,_radius];
_mrkCross setMarkerAlpha 0.2;

_mrkBorderName = format["%1BorderMarker",_zoraZone];
_mrkBorder = createMarker[_mrkBorderName,_zoraPos];
_mrkBorder setMarkerShape "ELLIPSE";
_mrkBorder setMarkerBrush "BORDER";
_mrkBorder setMarkerColor "ColorRed";
_mrkBorder setMarkerSize [_radius,_radius];
_mrkBorder setMarkerAlpha 1;

    Any chance we can get a demo mission? My attempts at following the instructions simply throwing up errors :p

      Oops! Added a demo mission to the first paragraph. It includes the debug mode for the ZORA module so you can see it at work as well.

    Awesome. It’s nice to find out what this module actually does, after having it in game for the last year and not knowing what the hell to do with it.

    Is there a way to reverse it so that if they cross into the zone they will spawn. cause im working on a mission on takistan map and i dont want players going to the the middle of the map.
