How to add alerts in my other scripts?

Here is how to do it!

1. First, go to karma-dispatch/client/custom_alerts.lua and add your custom alerts like this

local function Shooting()
    if not CheckWhitelist() then
        local coords = GetEntityCoords(PlayerPedId())

        local dispatchData = {
            message = 'Gun shots reported',
            codeName = 'shooting',
            code = '10-71A',
            priority = 2,
            coords = coords,
            street = GetStreetAndZone(coords),
            assigned = false,
            alertTime = nil,
            jobs = { 'police' }
        }

        TriggerServerEvent('karma-dispatch:server:notify', dispatchData)
    end
end exports('Shooting', Shooting)

After you add that you can export it where you want it like (in any script) like

exports['karma-dispatch']:Shooting()
