Static variables

Do they exist?

Not exactly what I meant. I meant like the way the static keyword works in C functions. As you probably know, so that variables retain their values even after the function's end, but can't be accessed script-wide, just in that function.

For example:

PHP Code:


		
			
function onCreated() {
 for (temp.i = 0; temp.i < 10; temp.i++) {
  echo(staticTest());
 }
}

function staticTest() {
  if (temp.staticVar == NULL) temp.staticVar = new TStaticVar();
  temp.staticVar.var1++;
  return temp.staticVar.var1;
}

outputs this:

PHP Code:

C function scope static variables are pretty ****ty, at least ask for C++ static members.

Store them in a server. or a DBNPC if it's that important I guess.

Sounds like there'd need to be some kind of class implementation (which I'd love)? I'm not sure. I know little about C++ and C for that matter. What I was asking for seemed best represented by what they have in C.

Just use global or object variables.

Edit: I also have to say that I think GScript should be scrapped and replaced with Lua. GScript is too inconsistent.

You could have a DB NPC called Static Variables or something..

PHP Code:


		
			
function onCreated() {
  staticvar = this;
}

Then in other scripts just reference it like so:

PHP Code:


		
			
function onCreated() {
  staticvar.crazyexample = 100;
  echo(staticvar.crazyexample); // 100 should appear on RC
}

I wasn't aware that DBNPCs were guaranteed to be accessible on clientside at all times.

I would suggest having a system weapon create a TStaticVar.

Good idea, Inverness. I've got an idea brewing which is based of what you've said.

Please stop those off-topic nonsense comments.

Static function-variables are quite interesintg in C/C++ although at the end they are just global variables. So we don't necessary require them, although it's true that it's sometimes good to have some real secured placed where you know that other scripts cannot interfere (another reason for the idea of private variables).

WILL NOT HAPPEN.

Now that we've cleared that up, please move on with your life.
