Introduction:
Reading this tutorial:
- Important Information is in Bold and Quotes.
- This tutorials is in "community proof-read" mode.
I've noticed a large amount of people using patch_mp's that don't know how to make them themselves. Although there are many people here that are willing to make them for them, the small, simple requests are annoying. Modding Patch's isn't that difficult.
Somethings To Know:
-Patch's are coded in a C++ like language. (NOT C++, but alike)
-Patch's cannot be ANY larger than 177 kb.
How patch_mp.ff works: (Concept)
When loading code, the xex will load the patch, and then the everything else. The code found in the patch will overwrite everything else. -- Correct me please?
SO I guess it's time to start. You can download everything you need in this tutorial Here:

- To download fresh new patch's, or a default_mp.xex we can go to "Download".
- To Open a patch File, go to File > Open.
- Patch files MUST be named "patch_mp.ff" NO exceptions.
2) Now let's open up our new, clean patch.

Here you can see the layout of the program's editor.
- On the left side (Black) , you can see the .gsc files the patch contains. Click one to open it in a tab.
- On top (Red) you will see the four tabs where you can open up to four gsc's at once.
- The larger (Green) portion of the screen is where you can view and edit the gsc you have selected.

Q: What are GSC's?
A: These are the files that MW2 stores code in. A patch contains certain GSC's that have been modified from the originals found on the game disc. (See "How Patches Work" Above) An example of the most popular GSC is _missions.
Into The Patch - Opening
1) Click _missions.gsc located in the GSC viwer (left panel)

The Code - Format / Adding Code

Format said:
First, you will can see the code is split into sections. These sections are started with a label. [Shown Here as Example()] They can be called upon at any time (I believe it has to be before the section?) using "thread" or "self thread" meaning "execute".
Example()
{
//Example
}
Next thing you will notice in the code is the "tier" system, as I like to refer to it. This system makes the code very easy to read, and separates functions.
How it works:
- "{" depicts that the line after will be ONE more tab in.
- "}" depicts the code before will be ONE more tab in.
Example()
{
If (self.name == "monarchy")
{
// Code Here
}
else
{
// Code Here
}
}
That above is a completed section.
1) Let's scroll down in _missions.gsc until we find the section labeled "OnPlayerSpawned" (Red)

Let's get some code going. We are going to start with something very simple, and just add a DVAR for all the players to have.
To find code to use, let's go to the "Managed Code List"
We're going to add the DVAR to earn XP in System Link and Private Matches: onlinegame "1"
To do this, lets get the add dvar code:
setDvar( "dvar", value );
And fill it with our own values:
setDvar( "onlinegame", 1 );
Then we will add it JUST after
self thread monitorSprintDistance();
Note: This photo also explains the default onPlayerSpawned function.

Now let's add some harder code. Let's make it so when we press a button, we become invisible.
To do this, we are going to add a new section. Lets add this just below the last "}" under out onPlayerSpawned section.
goInvisible()
{
// code
}
There is the base for our section. Now let's make it so the section is executed on player spawned.
add
self thread goInvisible();
After
setDVAR( "onlinegame", 1 );

Now we need to add the button pressing. This is simple, and very easy to remember. The hardest part is assigning the button. In our case we are going to use "Dpad_up".
Our code should look like:
goInvisible()
{
self notifyOnPlayerCommand("dpad_up", "+actionslot 1");
for(;
{
self waittill("dpad_up");
}
}
}
Now, we can add Hide function "self hide();"
We want you to hide after you hit the dpad, so let's make sure we add it after "self waittill("dpad_up");.
goInvisible()
{
self notifyOnPlayerCommand("dpad_up", "+actionslot 1");
for(;
{
self waittill("dpad_up");
self hide();
}
}
}

Now, anyone who has an extensive knowledge of C++ will recognize the code that appears. This is because the code is based on C++. Most of the things you see and use will be similar, so If you ever need help, C++ is your closest reference, besides the game code itself, of course. On this note, The easiest way to learn how to read and write this code is to study it. Read pieces and try to determine what they do to the game.

thanks.
thanks.
There is a new patched default_mp.xex TU5. I can't post it because it's illegal. But you can get the TU5 xex patcher and patch one yourself it's not hard. Or message me and i will send it to your email or something.
