Intro | Entity types

Laser

A line between two points. Detects anything which breaks the line between said points. When the line between the points is broken, events or callbacks can be triggered. Lasers can be oscillating between two end points as well. The color and opacity of the lasers can be adjusted dynamically.

Controller

A hackable controller panel which has the ability to temporarily disable defined lasers or trigger a callback function; on both: success and failure.

Alarm

An auditory and visual alarm. Once triggered it will play off an alarm sound and flash lights for a defined duration.

Usage | Basics

To call the exported functions, use the FiveM exports.

Example exports['kq_security']:CreateLaser(name, data)

Laser event triggers

As seen above, lasers can trigger events upon trigger. See below to find out more about the structure of these events

Triggers is a table of multiple event triggers. These should contain the following values:
event - string
the event name which should be triggered
type - string - options: server, client
The network type of the event
parameters - table
Parameters which will be sent in the event as its parameters

Example:

data.triggers = {
    {
        event = 'kq_security:dispatch:client:trigger',
        type = 'client',
        parameters = {

        rgb = { 100, 0, 0 },
        range = 15.0,
        intensity = 5.0,
    }
}

local alarm = exports['kq_security']:CreateAlarm('myUniqueAlarmName', alarmData)

--- Now, if you wish to trigger the alarms manually/from your script. You'd do the following (on each client)
alarm.Trigger()

Synchronised alarms

If you want to trigger alarms for all clients at once. You may use the server event:

kq_security:alarm:server:trigger

This event takes a table containing the lasers as its argument. Example:

TriggerServerEvent('kq_security:alarm:server:trigger', {
    alarms = {'alarm1', 'alarm2'}
})
