Description

Description:: Draws a laserbeam and a lightpoint at the impact location of the laser.
This command has to be executed every frame - see Arma 3: Mission Event Handlers - Draw3D.
Lasers drawn with this command are subject to the same limitations as weapon attachment lasers. These limitations are defined in the CfgIRLaserSettings config class.
Groups:: Interaction Lights

Syntax

Syntax:

drawLaser [position, direction, beamColor, dotColor, dotSize, beamThickness, beamMaxLength, isIR]

Parameters:

position: PositionASL - the laser's origin position

direction: Array format Vector3D - the laser's direction vector

beamColor: Array format Color (RGB) - laser beam color. The values can go way above the usual 0..1 range as they also act as emissivity brightness

dotColor: Array format Color (RGB) - impact dot color. Set to [] to use the same value as beamColor.

dotSize: Number - impact dot size; if set to 0 the impact dot will not render

beamThickness: Number - laser beam thickness scale; if set to 0, the beam will not render

beamMaxLength (Optional, default: -1): Number - the maximum length of the laser beam. Special values:

-1: No limit other than that defined in CfgIRLaserSettings
0: The drawLaser command is ignored

The maximum length of laser beams defined in CfgIRLaserSettings can not be exceeded, not even by setting this parameter to -1.

isIR (Optional, default: true): Boolean - whether the laser and impact dot are only visible with Night Vision / Thermal Imaging

Return Value:

Nothing

Examples

Example 1:: Give the player a laser eye: addMissionEventHandler ["Draw3D", { drawLaser [ eyePos player vectorAdd [0, 0, 0.1], getCameraViewDirection player, [1000, 0, 0], // Bright red [], 5, 20, -1, false ]; }];
