Need help with variables.

[crushenator 10]

I've spent hours now trying to figure out how to use global variables to no avail.

Long story short of what info I'm after is where and how to assign a variable that can be accessed from scripts, triggers, waypoints by all players on a server and can be used as the condition for triggers, units. Anything really.

Below is one attempt i've made to work with a variable.

In this particular instance I've got in the init.sqf (i'm not even sure if i need this)

myVar = 1;

Then I've got a helicopter with an init containing

_mytest = introheli addaction ["Send helicopter away", "mytest.sqf"];

and in mytest.sqf I've got

private ["_heli", "_caller", "_id", "_heligroup"];

_heli = _this select 0;

_caller = _this select 1;

_id = _this select 2;

_heligroup = group (assigneddriver _heli);

Pork = Pork + 1;

if (pork >= 4)

{

_heligroup move getpos woot;

};

So I guess what I figured would happen is if I select the action available on the helicopter 5 times then the helicopter would fly away.

Where am I going wrong here? Thanks for the help

First of all you need the -showScriptErrors parameter in your game shortcut to effectively debug scripts. In the case of an undefined variable, you just need to define them at some point before executing a script or command that uses those variables.

A variable is global when it doesn't have the _ in front. If you want it to become public (same for all clients), you have to use the command publicVariable "variablename" every time you want it to update across the net.

youve never initialized pork for starters...dont really know what else youre going for...also, coding conventions are such that variables never start with an uppercase letter...makes it harder to read for people looking at your stuff

Thanks guys just to clarify how I fixed it.

For starters I initialized pork in init.sqf and I also removed all the capitals. I also included a 'then' after the condition portion of the if statement.

I'm used to C++ syntax so didn't put a 'then'
