Client-created object (landmine) and Server references

[Stormridge 3]

Hi all,

 

I've done some searching and need input on how to approach a MP locality issue.

 

Background:

I have custom landmines that clients can create.  These are trip-wire mines based off of APERSTripMine_Wire_Mag, and they do custom stuff when triggered, including flares, sounds, and lights.

 

The client-side code catches the placement of these mines through the "Fired" eventhandler.  That event gets me the reference to the mine + position.  Then the client notifies the server that the mine was placed + position.

 

I want the server to monitor each mine and create the flares when the mine is triggered.  (I don't want clients doing CreateVehicle)

 

Problem:

Once the mine is placed, the client has a reference to the mine object, but I can't figure out how to pass the object reference to the server.  I am able to pass the position of the mine to the server, via publicVariableServer, but I'm 99% certain you can't pass the client object reference and have the server locate its own ref to that object.

 

 

I appreciate any tips.

 

Thanks

Probably setOwner can help you to transfer ownership of the object to the server?

I tried setting owner of the mine object to 2 (dedicated server) before triggering the public variable message to the server, but this does not work either.  

 

Passing the reference to the mine object in a publicVariableServer call results in a null object on the server side.

Object references are just strings (or something like that) and the mine is created at the client, but a global object (it's owner is the client, but it still lives everywhere else, in contrast to createVehicleLocal objects).

You can simply pass the reference as a variable to the server because the server will reference the object by the same string.

 

But instead of using PublicVariable I would use this:

_mine = param [0];//Called by the eventhandler

[_mine] remoteExec ["my_fnc_registerMine", 2]; 

And on the server you have a function "my_fnc_registerMine" like this:

private["_pos"];
_mine = param[0];
_pos = getpos _mine;

//There are better ways to handle this,. by whiel/waituntil is the easiest right now

while{!alive _mine} do {
sleep 1;
};

//Create flare 50m over the mine
_flare = TypeOfFlare createvehicle (_pos vectorAdd [0,0,50]);

This is not perfect, als the flare will also trigger when: The mine is defused or the owner leaves the server, but it sould be enough to answer your question and get you startet.
