allVariables – Talk

Let's assume that you're using global variables (since I'm not sure if local variables are actually in any namespace). setVariable is simply a handy means of setting a variable, so it would return the variables in your first and second example as well as if you had used missionNamespace setVariable ["myVariable",0]. --SilentSpike (talk) 21:20, 12 December 2014 (CET)

Creating a global variable automatically sets it into the missionNamespace:

someVar = "Hello, world"; hintSilent format ["%1", missionNamespace getVariable "someVar"]; //result: "Hello, world"

So there's no need for that. You can overwrite variables in the namespaces, just as you can overwrite global variables by reassigning them. But if you create objects which are global by default (like triggers), you can overwrite their reference (as variables are called by reference), but this will not overwrite the object itself:

myFancyTrigger = createTrigger ["EmptyDetector", getPosATL player]; _trigger = createTrigger ["EmptyDetector", getPosATL player]; missionNamespace setVariable ["myFancyTrigger", _trigger];

In fact, after this, there will still be both triggers, though the missionNamespace only knows the last one. The same thing would happen if you assigned the created trigger to a global variable and overwrite that. --Johnny
