Simple test
Start a dedicated server with a simple mission that has enableDebugConsole = 2 in its description.ext.
Join server with a client and in the debugConsole type
("hello" remoteExec ["systemchat",0,"myJipID"]) remoteexec ["hint",0];
And execute via server.
Further test (same as example zip)
//initServer.sqf
fnc_test = {
myJIP_ID = "hello" remoteExec [ "systemChat",0,"MyJIPID"];
if ( myJIP_ID == "" ) then {
myJIP_ID = "nothing";
};
publicVariable "myJIP_ID";
};
//initPlayerLocal.sqf
player addAction [ "RE", {
[] remoteExec ["fnc_test",2];
}];
"myJIP_ID" addPublicVariableEventHandler {
hint myJIP_ID;
};
