I released them public in the ph section.
And without subs you could find any code to.

your right, I saw your post first there in this section before I saw your post in warrock ph section, that's why.

very nice tut! You took much time of you to do this and only 8 thanks ;(

Thanks, it took longer to make then i expected.
Nothing we can do about that, if 2 people actually read the tutorial it would be allot.
Most of the guys on this site are to lazy to try something them self.

I think they dont know what is that ! some of there are KIDS

"some" xDD

im almost getting this mid function lesson
but i got confused with this one because i only have no menu base.

Code:

PlaceJMP((BYTE*)CoDJmpStart, (DWORD)CallOfDuty_Check, 7);

where / how do i put these ?

Code:

	__asm mov Check, 1 //We set our check to 1, (Check = Defenition => We entered game!)

Code:

HRESULT WINAPI myEndScene(LPDIRECT3DDEVICE9 pDev)
{
	if (Check){ //If we entered the game (which the midfunction will tell us.
		//We execute this code:
		CFont.MenuRender(pDev, 13, 600, (TCHAR*)Decrypt(STRING_FONT));
		pMenu->DrawCrosshair(WHITE, 36, pDev);
		return pEndScene(pDev);
	}
}

Code:

You place this in your DllMain
PlaceJMP((BYTE*)CoDJmpStart, (DWORD)CallOfDuty_Check, 7);

where / how do i put these ?

Code:

This is simply a check i made (defenition on top) to see if we have entered the game, if the function is looped we entered the game so we set the value to 1
	__asm mov Check, 1 //We set our check to 1, (Check = Defenition => We entered game!)

Code:

This is my endscene you dont need to use this in a nomenu
HRESULT WINAPI myEndScene(LPDIRECT3DDEVICE9 pDev)
{
	if (Check){ //If we entered the game (which the midfunction will tell us.
		//We execute this code:
		CFont.MenuRender(pDev, 13, 600, (TCHAR*)Decrypt(STRING_FONT));
		pMenu->DrawCrosshair(WHITE, 36, pDev);
		return pEndScene(pDev);
	}
}

I hope this answered your questions.

oh i see now. you have D3D . and i only have no menu. thanks!

Result:

Hello @AeroMan
How can you tell that the
__asm mov Check, 1 // will tell if we entered the game?

the following code only gets runned when the game loads

Code:

//Addresses= Addresses + 400000 (Start address)
DWORD CoDJmpStart = 0x5BF5D9; //iw3sp.exe + 1BF5D9 - 89 84 8F 34030000 - mov[edi + ecx * 4 + 00000334], eax
DWORD CoDJmpBack  = 0x5BF5E0; //iw3sp.exe + 1BF5E0 - 5B - pop ebx
__declspec(naked)void CallOfDuty_Check(void)
{
	//We replace the original code here because we simply make a check in this tutorial.
	//Replacing the eax with your val (mov eax, 10) could set your to 10 instead of dropping.
	__asm mov[edi + ecx * 0x4 + 0x334], eax //Original code (set ammo)
	__asm pushad //Push to stack

	__asm mov Check, 1 //We set our check to 1, (Check = Defenition => We entered game!)

	__asm popad //Stack to register
	__asm jmp[CoDJmpBack] //Jmp back to our original code
}

Because the part where we jmp to this function gets only runned when we entered the game.
For example: The game is loading, we set our ammo to full so we start with a full clip of ammo when we first enter the game.
This part where the ammo is first set meant we have spawned and our character is ingame.
So we jmped from that code block (where the game sets it's ammo value -> we entered the game) to our code.
This means we executed our code the moment the game has set the ammo.
So then our code sets the 'Check' to value 1, meaning we entered the game.
Our default value was 0, so if it's 1 it has obviously executed the code.
At this point we execute our endscene or whatever you would like to.

Code:

if(Check){ code here }

So if we entered the game (Check = 1) the code is true and we execute the code between that check.

EDIT: __asm mov Check, 1
can be seen as Check = 1;
We simply put the value 1 inside Check.

I hope this makes sence, if not let me know and i'll try to explain it diffrently

Nice Tutorial- it's better late than never to read this keep it up

Thank you my Friend

after many time spent reviewing @AeroMan 's tut, i finally understand it's concept. now its time to try coding what I learned.
thank you i hope i can do this. HAHAHA
