Trigger action visible only to the player who launched it?

[finguide 1]

This may be an old question, but I have no idea about the words that I could use to search already existing threads.

I'm creating a simple chopper autorotation practice mission and I use Radio Alpha (and special zone) to set chopper engines off, but it's little impractical if every chopper engines turn off when one player wants to shutdown his engine and try to land. My question is, how do I restrict trigger action to only the player that launched it?

on act:

(vehicle player) setFuel 0;

triggers beheave local in MP so should be no problem there.

But as it's a radio trigger would that apply, as you can't find out who called the trigger.

Wouldn't it fire on every machine and any player in a vehicle have no fuel.

He could just create multiple radio triggers (Alpha, Bravo...) and use this line

Radio Alpha:

(vehicle p1) setFuel 0;

Radio Bravo:

(vehicle p2) setFuel 0;

Just make sure every player knows what radio (Alpha, Bravo...) he should use.

You could enter a description for the radio triggers like:

"Player 1 chopper engines off"

Exactly this is the problem. Using different radio trigger to every chopper isn't an option, because there's not enough radio triggers available. On the other hand, the special area shutdown works (engines of choppers in green zone will shutdown in 10 seconds from entering to zone). When chopper enters zone, three triggers will activate:

Activation BLUFOR, Present 
On act. list_to_kill=thislist

Activation BLUFOR, Present
Countdown 10 seconds
On act. {_x setFuel 0} foreach thislist;

Activation BLUFOR, Present
Countdown 5 seconds (sync with shutdown)
On act. _handle = execVM "Shutdown.sqf" (=hint row "Ready..." "Set..." "Go!")

One more question; how to get rid of super annoying "File xxxxxx not found" notification that appears when I play a custom sound in multiplayer? The sound is played but everyone gets still the error message when trigger playing the sound is activated. Sound is in MPMissions\Mission\sound, and I have it determined in description.ext file (class cfgSound) etc.

I'd use an addaction which is only available to the pilot when inside the testing area.

This placed in the heli init. trigtest can be the name of the trigger or any object.

place in vehicle init

this addAction ["Kill Engine","Kill_engine.sqf",[1],0,false,true,"","player == driver  vehicle _this and player distance trigtest <350"];

Kill_engine.sqf

_this setfuel 0;

The option to kill the engine will show in the menus on the left of the hud.

F2k Sel, I get the option to "Kill Engine", but nothing happens when I select it. I have Kill_engine.sqf and that

_this setFuel 0;

in it.

I can't see what your doing wrong but it works perfectly here.

try this.

addaction driver

I checked it and changed _this setFuel 0; to vehicle player setFuel 0; and it works now like charm. Thanks!
