It is limited to the police vehicles because all these vehicles use the same script in which the animationPhase is a float value like 0.2 , 0.4, 0.6 and so on.
The Jonzie Ambulance instead uses integer values like 2, 4, 6 and so on.

Now the problem is that due to some reasons these float values are not transferred to all clients properly. Even numbers like the ones used in the ambulance script are transfered correctly.

I assume it has something to do with bandwith optimization. Which in general is a good thing but in this special case screwed us all over :D

Anyhow if u need a quick fix just edit the scripts in your pbo's to use even numbers or round the float values to a correct value like this:
_phase = _phase * 10;
_phase = round _phase;
_phase = _phase / 10;
This yields the correct value.

But this is rather annoying work because this has to be done for every vehicle and for multiply scripts like sirens, lights and so on

I was just thinking that during the day. Thank you for this info. I just hope that the other people with this issue get back to this as well as the sirens and lights are a big thing in these life mods.

Is there any update on this info or?

Any updates on a fix?

I have been waiting too. It must be an issue if no one knows what's going on

What is the fix...?

Who knows, bohemia will not comment on the eta of this fix. Sad. So may communitys just here in limbo waiting on people who fail to care or listen. Bohemia, if you start to care about your customers please take a look at this. My community has 2000 players, 100+ active daily and I know there are bigger communitys then us out there waiting on the same fix. Please just give us a update, something, anything.

Well the fix that Balu stated, does work. You have to put that in just about every file in the police car mods that use animationPhase. It took me a little while to do but I did it and everything is working correctly now. Hope that that will help all that need it

condition = "driver this == player && (this animationPhase 'ani_lightbar' != 0.1)";

				statement = "this animate ['ani_lightbar', 0.1], this animate ['ani_directional', 0.2]";

So you make the .1 and .2 whole numbers?

_phase = _phase * 10;
_phase = round _phase;
_phase = _phase / 10;

Put that right under where the _phase variable is and it should work. You may need to change the variables in on of the files because you have to do it 3 times. I don't remember which one it is

I can confirm the fix mentioned above has fixed the lighting issues on the server I am running.

However when the code 3 option is selected only the local client can hear it not other clients. I tried the above code in the sirens script aswell already. Is there another fix for this?

Take a look at the variable "_phase". Thay might not be the variable you need to use. The phase may be assigned to a different variable.
