I was in the passenger seat, in the helicam view, I pressed G to turn on the spotlight, the manual spotlight did not come on for others as I looked around unless I kept turning it on and off until they said they could see it. I then swapped over with someone else where we then had the same issue. We also tried looking at a vehicle and pressing space to lock on with the spotlight enabled, this resulted in the same issue.
Mysterious. In what sense did the manual spotlight (helicam) work at all for other clients, when you turned it on and off continuously?
Based on your description, I am guessing that when you turned it on and off continuously they saw a flickering spotlight and not a constant beam? From which we can presume that clients are in fact getting a spotlight but it gets cut off almost immediately, so the pilot flicking it on and off rapidly just provides a series of spotlight flashes that quickly disappear?
Great plugin! I’ve changed a few things, one of them is that I’ve added the ability to zoom in/out using a controller, since a controller doesn’t have a scroll wheel 
. I’ve also managed to have the spotlight follow the camera position.
The only thing I can’t figure out is to sync the helicopter cam with all people inside the helicopter (if they enable the camera), and have that spotlight (using the
DrawSpotLight(camcoords, forward_vector, 255, 255, 255, 300.0, 10.0, 0.0, 2.0, 1.0)
function) be synced to everyone on the server.
If anyone knows how I can achieve that, please let me know.
(Code) zoom controller support
- Zoom in (hold) L3 (press left stick)
- Zoom out (hold) R3 (press right stick)
function HandleZoom(cam)
if (IsControlJustPressed(0,241) or IsControlPressed(0, 230)) then -- Scrollup & Left Stick (L3)
fov = math.max(fov - zoomspeed, fov_min)
end
if (IsControlJustPressed(0,242) or IsControlPressed(0, 231)) then -- scrolldown & Right Stick (R3)
fov = math.min(fov + zoomspeed, fov_max) -- ScrollDown
end
local current_fov = GetCamFov(cam)
if math.abs(fov-current_fov) < 0.1 then -- the difference is too small, just set the value directly to avoid unneeded updates to FOV of order 10^-5
fov = current_fov
end
SetCamFov(cam, current_fov + (fov - current_fov)*0.05) -- Smoothing of camera zoom
end

To sync the free aiming spotlight you only need to sync the forward_vector, since the cam/heli coordinates can be obtained independently by each client. Syncing the forward_vector AFAIK must be done either by continuous client-server events or by client-client communication via decorators.
I have tried both methods and the former method creates a constant flickering light (as well as serious load on the server) and seems sub-optimal. The latter method seems more efficient and is attempted in the modified script above. I think it is workable but is somewhat laggy for remote clients when the camera/spotlight is repositioned.
I have reworked the syncing of the various spotlights modes on the modified version, which were disfunctional in multiplayer, and I will post something soon I hope, after testing a bit more.

Alright thanks for the info, I’ll keep an eye out for that 
Well if anyone wants to give this a ‘whirl’ below is a revised attempt to modify mraes’ script, as I described above. This hopefully fixes the multiplayer sync issues. I also tried adding a new setting to increase/decrease the manual spotlight radius (using capslock/leftshift keys) and to sync this and rjross2013’s brightness setting across clients.
I have tested it on FX and CFX servers with one other person (no serious stress testing on a big server). The only anomaly I noticed is that periodically the tracking spotlight will disappear at far distances on the remote non-pilot client, a bit before it disappears for the heli pilot at the appropriate spotlight maximum target distance as set in the configuration. I believe this is because the target vehicle is lost on the network for the remote client, for some reason, even though the target is set as a mission entity. The syncing of the manual free-aiming spotlight works but is somewhat laggy during adjustments for non-pilot clients – AFAIK this is unavoidable but to me it is still worthwhile.
Under the hood there are other similar peculiarities because even with an newer resource manifest with reported networking updates, I am not always getting global networked entities with 100% reliable netid <-> entity conversions. But with some fail-safes to compensate, the target vehicles and corresponding spotlights do seem to be getting synced reliably (in my testing anyway).

Just tested it and it seems that its a little glitchy getting the spotlight to work when you have a pilot and copilot trying to get the spotlight on at the same time, but as soon as one of them exits the camera it works perfect! Thanks!
A struggle for control of the spotlight?! Somehow I thought mraes had restricted the helicam to the pilot seat. Yes, I could see problems with the spotlight functions in a situation of simultaneous helicaming, so that may need to be looked at.
Nope, no restrictions. Adding the restriction that only one person may control it is pretty easy though.
@Loque Thanks for the nice improvements!
Would you have the helicam user trigger client/server events to broadcast to other clients (only other clients) that the helicam is in use, and then update when that user exits helicam?
What makes me nervous/paranoid is some unexpected event that prevents the variable getting reset properly, resulting in everyone getting locked out of the helicam. If say the pilot crashes the heli during helicam use then your helicam cleanup section should still run and a helicam_in_use variable could be reset no problem, I assume. But what if instead a pilot’s FiveM client crashes during helicam use?
Actually I wonder if a ‘HelicamInUse’ decorator might be better. It would avoid some potential issues simply because it would be a property of one particular heli entity. Not to mention ease of use of these decorators makes them so tempting. 
Sorry in advance if this is a stupid question. I am not a code guy. I am a streamer that wants to RP a news chopper.
Is it possible that a similar mod will work on the Frogger helicopter?
Yes, you only need to change a few lines of code. I can send you those lines later today if you want.
@Pitchit alright here you go.
heli_client.lua
Directly below this line:
local polmav_hash = GetHashKey("polmav")
Add one of the following lines for each type of helicopter that you want the helicam to work on:
local maverick_hash = GetHashKey("maverick") -- Maverick
local buzzard_hash = GetHashKey("buzzard") -- Buzzard
local buzzard2_hash = GetHashKey("buzzard2") -- Buzzard2 (without guns)
local valkyrie_hash = GetHashKey("valkyrie") -- Valkyrie
local frogger_hash = GetHashKey("frogger") -- Frogger
local frogger2_hash = GetHashKey("frogger2") -- Frogger2 (Trevor's Version)
Next, replace this function:
function IsPlayerInPolmav()
local lPed = GetPlayerPed(-1)
local vehicle = GetVehiclePedIsIn(lPed)
return IsVehicleModel(vehicle, polmav_hash)
end
With this:
function IsPlayerInPolmav()
local lPed = GetPlayerPed(-1)
local vehicle = GetVehiclePedIsIn(lPed)
local IsPolmav = IsVehicleModel(vehicle, polmav_hash)
local IsMaverick = IsVehicleModel(vehicle, maverick_hash)
local IsBuzzard = IsVehicleModel(vehicle, buzzard_hash)
local IsBuzzard2 = IsVehicleModel(vehicle, buzzard2_hash)
local IsValkyrie = IsVehicleModel(vehicle, valkyrie_hash)
local IsFrogger = IsVehicleModel(vehicle, frogger_hash)
local IsFrogger2 = IsVehicleModel(vehicle, frogger2_hash)
local isCorrect = false
if( IsPolmav or IsMaverick or IsBuzzard or IsBuzzard2 or IsValkyrie or IsFrogger or IsFrogger2) then
isCorrect = true
end
return isCorrect
end
Note that you can simply add/remove any of the “or IsXxxxx” parts in the last “if statement” to enable/disable that specific helicopter. I’ve not tested this with the latest version of the script but with a previous version this worked fine even on helicopters that don’t have a spotlight. But maybe in the new version this could cause issues if you allow helicopters that don’t have spotlights. (Not sure)…
Hope this helps. If you have any questions just reply or send me a PM.
EDIT: Btw this most likely isn’t the most perfect way to do it but since I’ve already changed my own code for this exact situation I just copied/pasted my code over here. If anyone wants to improve it, be my guest.

Thank you good sir, it’s nice to see this kind of support around here!

This works great, thank you!
Is there a way to get the speed of cars kinda like the DoJ server? If not cool if so great! Just get back to me but it would really be a killer if you could or tell me how to do it i have a little experience in the coding world.
If you are using the modified version a few posts up then you should be getting the speed of cars by default, when you use the helicam and zoom in on an individual car. If you then press SPACE you can lock on the car and continue to get its speed while in helicam and even after you exit helicam.
If you are not seeing the speed, then maybe you hit Q by accident, which toggles the vehicle display mode between speed+model+license / model+license / no display.
