That is just it, they dont sync it because its not needed to sync. The spotlight is just for singleplayer, and it would be easy to sync if it was stationary.
But vehicle position is synced across clients is what I am saying. I think you missed what I meant. My thought is that vehicle position is synced from client to the server and back to other clients. Can we reverse engineer this method and apply it to the spotlight angle?
I have been working on enhancing the spotlight side of things since mraes released this amazing mod, but I’ve had lots of trouble, and rjross2013’s great additions needed to be made compatible too. I will post the script in the next message which you can jump to if you want but please note this is to some extent a work in progress. In single player everything works for me at least but I have tested very little of it for syncing across players. Here are the functions I was going for:
(1) three switchable spotlight modes: (a) the ‘forward spotlight’, the only proper though static cone of light, which mraes originally included with syncing across clients and which I have basically left as is; (b) the ‘manual spotlight’ (with auto-tracking option, all via helicam) introduced by rjross2013. I have tried to also make this sync across clients; © a new ‘tracking spotlight’ (simple circle of light) which potentially follows a target vehicle when the pilot is not using helicam. I have also tried to sync this across clients.
The spotlight modes are all toggled using mraes’ configurable input, by default ‘G’. While using the tracking spotlight this key will turn on and off the tracking spotlight (pause it) until the target is lost or released by the pilot, so to switch from say tracking spotlight to forward spotlight, you first release the target vehicle being tracked and then press G to engage the forward spotlight.
(2) vehicle target lock obviously must persist now after exiting helicam, and is terminated when target distance exceeds a configurable max target distance or when the heli pilot releases the target lock with the configurable key (default space bar). If a new target vehicle is acquired while the tracking spotlight is active, the spotlight should switch targets and track the new one.
(3) vehicle information display also persists now after exiting the helicam view when a target vehicle has been acquired. It now also by default includes vehicle speed. The display modes can be toggled between radar+model+license / model+license / no display using a configurable key (by default ‘Q’).
As a technical aside on syncing, I first tried to do all of this using client/server events but lost most of my hair from ripping it out. In the end, the first version was not reliable for syncing the tracking spotlight but probably could have been fixed. The manual spotlight, as mraes and rjross2013 were discussing, suffered the consequences of inefficient client-server communications. I got it synced but upon testing with another person, the light would flicker significantly.
This new version relies mostly on ped decorators to pass some variables from heli pilot to other players. I’m no programmer but this method was way easier to work with. The manual spotlight seems more efficient (client->client) since the spotlight quality appears to be fairly stable. Once again, all of the syncing needs full testing in a multiplayer environment.

Seems like fine work! 
I hadn’t thought about using decorators for this.

Sounds awesome. Excited to test this tomorrow with multiple players
FYI I edited the post above with new client code, so if you grabbed it before this message is posted, grab it again.
I fixed a minor glitch and also realized that manual spotlight was not transitioning to tracking spotlight. Now it should. So when using the manual spotlight within helicam to auto-track a vehicle, you can exit helicam and the tracking spotlight will take over and continue to track the vehicle.
Just tried your script with a few people and it’s a definite improvement. We found though that when we turned the spotlight on, it wouldn’t come on for others unless the camera operator kept turning the light off and on.
did you wait for it to sync sometimes takes time to sync between everyone present …sometimes
WolfKnight, which spotlight modes did or didn’t do this? The tracking spotlight outside of helicam view or the manual spotlight via helicam view?
Also, it would help if you describe in more detail what did happen: e.g. pilot turned on manual spotlight (pressed G in helicam view), spotlight came on for him properly but did not for others (at all or just a flicker?), unless pilot kept flicking on and off continuously? Weird.
That’s disappointing if confirmed by others.
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.

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?
