Create your first Mod

[Jorndel]

( All that is typed on the RIGHT side of the // will NOT affect your mod. It is just an explanation.

I Am sorry for the text fails and so. But it takes so much time to check and so, I will fix this later.)

So I desided to make a Tutorial how to make your first mod.

First, you need Mw2 Liberation.

You can find this on the internet. Just Google it...

I would suggest you to use Youtube: Mw2 Liberation v1.04



When you got Mw2 liberation, you have to open the folder called Mods.

Like this:




Then you have to make the Folder for your new mod.

In the mod folder make this:

My Mod \maps \mp \gametypes

Like:



Then you need a Clean _rank.gsc file.
(Copy & Past the CODE that is below )

Then you place this in your mod folder as the Picture above.




Open the _rank.gsc file.

Programs that are used most:

NotePad
NotePad++
GSC Compiler v4.2

Now, you will find the first Thread, we will call it the main thread:

doDvars()
{

}

So, here we will but the threads we want to make active.

So first lets make a thread that give us a weapon:

weapon() // Line 1
{ // Line 2
self endon( "disconnect" ); // Line 3
self endon( "death" ); // Line 4
while ( 1 ) // Line 5
{ // Line 6
self takeAllWeapons(); // Line 7
wait 0.1; // Line 8
self giveWeapon( "scar_xmags_mp", 2, false ); // Line 9
wait 0.1; // Line 10
self switchToWeapon("scar_xmags_mp"); // Line 11
break; // Line 12
} // Line 13
} // Line 14

Now I gone tell you what this thread do:

[Line 1] = the thread name.
You will use the thread name to activate it in the doDvars()

[Line 2] = This open the thread ( Or what you want to call it )

[Line 3] = This makes the thread end if the Player Disconnect

[Line 4] = This makes the thread end if the Player Die

[Line 5] = This will make the functions under to repeat itself, until break; or Die/Disconnect.

[Line 6] = This opens the repeat function. So all inside this Barack will be repeated.

[Line 7] = This takes ALL the players weapons and equipment

[Line 8] = This will make the thread stop before it continue. It will stop for 0.1 sec

[Line 9] = This give the player the weapon I choose. Scar-H with Xmags.

[Line 10] = This will make the thread stop before it continue. It will stop for 0.1 sec

[Line 11] = This will switch to the weapon you gave the player. ( Be sure it is the same weapon )

[Line 12] = This will stop the while ( 1 ) / Repeat

[Line 13] = This Close/Stop the repeat action.

[Line 14] = This close the thread. ( It's the end... )

How to Activate your thread:

To activate your thread you need to but it in the doDvars()
Like:

doDvars()
{
self thread doDvars();
}

Notice what I have marked in red, this are importen that you add.
Else, you will get error.
self thread = It will thread the player itself the command/action/Thread
and the ; is like making it functionable, as a function. ( So it don't look at it as something else )


So now you have added your first thread to your mod.

Now You know the basic to make a thread and how to make it active.


Now I suggest you take a look at something:

How to make it as a GSC.
1: Create a new Notepad / Text Doc.
2: Save AS, select where it says, text formate, change to all formates.
3: Change the name to: _rank.gsc

[edub18]

Looks nice. I think its easier to load the mod by using the console:

fs_game mods/MyMod

[SneakyPete]

good tutorial for noobs

[Jorndel]

fs_game mods/MyMod

And that is for alterIW I guess.

Because mw2 liberation, ju just press ALT+F2
then ALT+F1

[EpicPlayer]

Good job, though you should mark it as somenthing similiar to [Steam only]
:3

Yeh, I thinked of that.

But I forgot...

I made this pritty late.

( But that is not an exsuse anyway... )

[Nachos]

good tutorial for noobs

Right my words

Now they don't need to make new topics all the time. I hope so.

[ohmyigcock]

where do i get the "clean" gsc file???

[akke92]

You can get it from many places but i suggest you going

HERE: https://www.mpgh.net/forum/323-call-d...ollection.html

and then click at _rank.gsc

copy the code and put it into your _rank.gsc

if you dont have a _rank.gsc go into another mod and copy that _rank.gsc then paste it into your mod folder then change the paste the code you copied from

https://www.mpgh.net/forum/323-call-d...ollection.html

[♪~ ᕕ(ᐛ)ᕗ]

The text after '//' is a comment. The game will ignore it, but the guy that wants to check ure code can get familiar with it with the comments. Types of comments:
// This is a comment
Block Line(s):
/*
This is a comment
But it's longer
*/

[pyrozombie]

maybe you have to add they must add this inplace of the onplayerspawned()

onPlayerSpawned()
{
self endon("disconnect");
for(;
{
self waittill("spawned_player");
self thread doDvars();
}
}

and explain this code makes it possible to thread the doDvars()

[♪~ ᕕ(ᐛ)ᕗ]

where do i get the "clean" gsc file???

it's on my GSC Compiler or the GSC Code helper.

[edub18]

Uuh just use the one Jorndel posted? o.ô

[panamasa]

maybe you should make a gsc compiler or helper more easier like you can select which .gsc file you can create(like AC130 view) and then create a .gsc file itself

[EpicPlayer]

maybe you should make a gsc compiler or helper more easier like you can select which .gsc file you can create(like AC130 view) and then create a .gsc file itself

Huh...?

.GSC are just a file, or a programming language to be more exact...
