If you make a cog file, and put a variable in it (EG a=0) Then how do you get other cogs to recognise that variable and realise that if the variable changes (EG to 1).

You got to pass the var onto the other cog or use a global variable, which is the

"items.dat"
"SetThingUserData"
or something else.

To pass use,
SendMessageEx(cog, message, var1, var2, var3, var4);
But this way, it's hard to retrieve the "cog" unless you specify via JED.

or add new entries in the items.dat and use
SetInv(player, 116orAbove, 1);
and
GetInv(player, 116);

or use SendTrigger
SendTrigger(-1, 123, var1, var2, var3, var4);
and in other cogs

trigger:
if(GetSourceRef() == 123)
{
sentVar1 = var1;
another = var2;
whatever = var3;
oneMore = var4;
}

The only global value is the "items.dat" method and others are passing the local var to other cogs.

And as for SetThingUserData, it can set a unique var onto a "thing" globally

SetThingUserData(player, yourValue);
and
GetThingUserData(player);
will return the value set.
