[multipage=Variables - Data Storage]


The variable is a basically a string which stores data.
here's how you will see it.

    

Variable = "learning variables";

now, the string 'Variable' now equals "learning variables".
if i now was to println this, like 'self iPrintln( Variable );
it will output 'learning variables;.

this is probably the most basic thing in GSC, there's also more to it but that comes into arrays which will be explained later on.
[multipage=Threading - Calling a function]


Threading is pretty much every function which you will find, without this your code snippet will not act.
also again, this is pretty basic.. but it can be mistaken.

here's a basic snippet.

    

self thread Tutorial();

now, if i was just to put that into my patch it will error.
the game will look for the thread 'Tutorial', which at the minute is not functioned; this error will be 'Unknown function'
therefore i will need to add my function somehwere.

    

Tutorial()

{

	self iPrintln( "hi" );

}

now up on threading that, say if i threaded it up on player spawn my output will be a line print of 'hi'.
yes, this is how your god mode ect are called, however you need to coding for them.

you see how i have the 'self', thats really self explanitory.. it will act up on myself, but that can be changed..

    

level.players[ 1 ] Tutorial();

that will function for the level.player (player) which has the entity number of 1.

now you might see '<self> thread Something();'
the 'thread' is only needed if it's inputing data from/ into another thread, so if i was to doo..

    

printText( text )

{

	self iPrintln( text );

}

'self thread printText( "hi" );'
which now leads us onto arguements
[multipage=The strTok - Split Statement]


The strTok is a split statement, it will split every statement given up on the char which it should be split at.
here's a syntax version of how it should be used.

    

< new string to input > = strTok( < string to input > , < split char > );

- New string to input
this is will set the statement's too, remember.. if there's more than one statement it will need to be set at an array.

- String to input
this is the string/ text which needs to be inputted then split, remember it must contain the split char or it wont be split.

- Split char
this goes for aboth, it's a single char placed in a ".. for every 'split char' in the input string it will split it, then carry on splitting until it will no longer can be splitten.

here's a full example of usage.

    

printlines( texts )

{

	output = strTok( texts, "|" );

	self iPrintln( output );

}

there i've set the input string to an arguement, it works the same just called differently.
so here's how i would call it.

    

self printlines( "this|is|a|tutorial" );

that will print a new line for this, is, a, tutorial.. so it will look something like..

    

this

is

a

tutorial

strTok is pretty useful and can compress your code much more than over statement.
if your having trouble of don't understand how to use this then message me, i'll help you out with it.

but i hope i explained as best as i can.
[multipage=The 'If' Statement]

The "If" statement- By .Choco

[/center]

The If statement is a major part of Call of Duty Scripting. It can be used in many ways. What it does is tell the game that if a certain condition is true, false, or equal to a value, do a certain thing. Here is an example of one:

    ExampleFunction()

{

	if(<variable> == <value>

	{

		self iPrintln("poopy");

	}

}

So let's break that down a bit.

    if(<variable> 

Any variable can be here, whether it is attached to yourself or the level.

     == 

"==" translates to "is equal to". There are other arguments that can be placed here:
"!=" - is not equal to
"<" - is less than
">" - is greater than
"<=" - is less than or equal to
">=" - is greater than or equal to

    <value>

Your value goes here. It can be a number, a string, true, or false.

After your if statement is declared, put a set of brackets under it and everything inside those will be executed if the statement is true (these brackets are not always needed, but for the purpose of this tutorial they will be).

Seem a bit confusing? It's not really. The if statement is one of the most commonly used scripts in all patches. One way it is very practically used is to determine who the host of a lobby is. The next script does just that:

    findHost()

{

	if(self GetEntityNumber() == 0)

	{

		self.isHost = true;

	}

}

GetEntityNumber() is a built-in function that returns your Client Number. Number 0 is the first to connect, which is always the host. So what this function says if that if your client number is 0, the variable "self.isHost" is attached to you and it is true.
[multipage=Using 'endon', 'waittill' & 'notify']


endon, waittill, and notify are very useful tools in CoD scripting. I will be breaking them down and explaining what they do and why it is useful.

Let's start with endon.
Here is a basic god mode script:

    

God()

{

    self endon("disconnect");

    self endon("death");

    self.maxhealth = 90000;

    self.health = self.maxhealth;

    while( 1 )

    {

        if(self.health < self.maxhealth)

        self.health = self.maxhealth;

        wait 0.1;

    }

}

Now I'm not going to break down the whole function, but let's look at the beginning of it.

    

self endon("disconnect"); 

This part tells the game that if you disconnect, terminate the God() thread. So if you lag out or leave, God Mode stops.

    

self endon("death"); 

This tells the game that if you die, terminate the thread. Simple enough right?

Now how does the game know what "death" and "disconnect" are? This is where notify comes in. In the game engine, if you die it automatically notifies the game with "death". If you disconnect, it notifies it with "disconnect". You can notify the game of something like this:

    

self notify("you_are_a_noob"); //This will notify your player's entity "you_are_a_noob"

level notify("you_are_all_noobs"); //This will notify every player "you_are_all_noobs"

The notify can be very practical for things like toggles. Example of a cg_drawFps toggle:

    

toggleFps()

{

    self endon("disconnect"); //if the game ends or you leave stops the function

    self endon("death"); //stops the function if you die

    i = 0;

    for(;

    {

        self waittill("toggle_fps"); //this will be explained shortly

        self setClientDvar("cg_drawFps", i);

        i++;

        if(i == 4) i = 0;

    }

}

To toggle the FPS counter, all you have to do is this:

    

self notify("toggle_fps");

It can be used like that to make your script much simpler.

Now on to waittill.

Go back and look at the Fps toggle script. See this part?

    

self waittill("toggle_fps");

Waittill tells the function to wait for something to be notified before continuing with the function. In the case of the FPS toggle, it tells the function to wait for "toggle_fps" before continuing. Very useful stuff

I hope I made this clear enough to help people out

Thank for this

You test every script? I have yet to see you release ONE SINGLE SCT that works like it's supposed to, if it even works at all

What scripts have you released?

Here is a little tutorial I wrote for endon, waittill, and notify:



Now I'm not the best GSC coder but I think I can help some people out

To be fair, when he made that "nuke" thing, I only found these errors

A couple of things to try and help...

Looks like bad syntax but I haven't tested it..

Mixing self and player in the same thread isn't very good.

Add some spaces to the Iprintlnbold. It looks ugly with the numbers running up the screen like that

Why do you have 3 RadiusDamages? The first one will kill everyone anyway..

You don't need to set a if(dis<101). You would need your trace to be within 101 units of you for it to work. (that's not very far away from your feet )

level.expbullt ~ You haven't defined that.

level.exp3 = loadfx("dust/dust_wind_fast");~ defined this but not used it..

level.exp2 = loadfx("weather/fog_daytime");~ defined but not used

What is level.mine.origin? Where is it?

Having the wait 2; after the RadiusDamage means that some people would respawn and be alive after the nuke goes off before the game ends..

And, because you have set the timescale to 0.3, the 2 seconds would last for about 6.666 seconds..

You are ending the game and setting "axis" team as the winner, what about if you are on the allies team?

And you need to reset all the dvars or you'll be stuck with the nuke vision when you start the next game..


Apart from that I can't see any problems...

Lies briefcase of doom works lol

Honestly I've been scripting gsc for a year and a half and eventually you just learn what works and what doesn't just by looking at it. I didn't mean to offend you, but the truth hurts. lol

---------- Post added at 10:37 PM ---------- Previous post was at 10:33 PM ----------



Ah I didn't mean it in a mean way But it's true lol

awesome bro, thanks for contributing.. once again !

Im absolutely shit at coding ... but im hopefully doing computer science at Uni in a year and this year finishing level 3 IT... but i just do what i can to make one F ucking random patch that everyone loves more than vaders :black:

and all you trolls out there stop picking on J&b he's gotta start somewhere.... but seriously before releasing script make sure it works bug free .. and shrink it as much as possible and then release.. because it waste others time.
