This command broadcasts a variable to all clients, but as soon as you change the variable again, you have to use publicVariable again, as it does not automatically synchronise it.

When initialising a public variable to handle JIP, you will usually first want to check if the public variable has already been (broadcast, received and) set locally. Otherwise you may inadvertantly overwrite the broadcast value with your default value.

To perform this check, use code similar to the following to first check that the variable is nil: if (isNil "PV_abc") then { // set the nil variable with a default value for server and both JIP & 'join at mission start' PV_abc = [7, 8, 9]; }; // else public variable has already been set due to a public variable broadcast.

Be sure to place your variable name in quotation marks. This may sound awfully simple, but many times I have forgotten to do this, and it has resulted in no end of headaches for me.
