Create your first Mod
( 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:
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:
Now, you will find the first Thread, we will call it the main thread:
So, here we will but the threads we want to make active.
So first lets make a thread that give us a weapon:
Now I gone tell you what this thread do:
How to Activate your thread:
To activate your thread you need to but it in the doDvars()
Like:
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:
You can also get the _rank.gsc for: ( Faster And Easyer.. )
_rank.gsc
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

Now, you will find the first Thread, we will call it the main thread:
doDvars()
{
}
{
}
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
{ // 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
[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... )
You will use the thread name to activate it in the doDvars()

How to Activate your thread:
To activate your thread you need to but it in the doDvars()
Like:
doDvars()
{
self thread doDvars();
