FMA + Godmode Script

I've been trying to convert the FMA + Godmode script to c++ to use for a trainer but I'm having difficulties with it and would appreciate if someone could tell me how exactly do I go about doing this. The script that I'm trying to convert is:

Code:

[enable]
alloc(IntersectRectHook,128)
label(intersectrect_return)
label(return_true)
label(return_false)


IntersectRect:
jmp IntersectRectHook
intersectrect_return:


IntersectRectHook:
cmp [esp],0071E82E // dEM // 85 c0 75 0C 8B 5C ? ? 45
je return_true
cmp [esp],0071E076 // phsyical godmode // 85 C0 75 35 ? 4C ? ? ? 44
je return_false
mov edi,edi
push ebp
mov ebp,esp
jmp intersectrect_return


return_true:
mov eax,1
ret 0C


return_false:
mov eax,0
ret 0C


[disable]
dealloc(IntersectRectHook)

I believe that a codecave is used for this and I've been reading how to do codecaves through darkspace's tutorial but this script seems different from the codecaves/scripts he uses in his examples so I'm not sure how to go about doing this.
I know that this script needs to be updated but I haven't had a chance to actually patch my game yet.

Any help would be appreciated! Thanks in advance.

Code:

unsigned long ulIntersectRect = (unsigned long)GetProcAddress(GetModuleHandle(L"user32.dll"), "IntersectRect");
unsigned long ulIntersectRectRet = ulIntersectRect + 5;

void __declspec(naked) FMA_ASM(){ 
    __asm { 
            cmp dword ptr [esp],0x0071ECEE // dEM
            je return_true
			cmp [esp],0x00720916// phsyical godmode // 85 C0 75 35 ? 4C ? ? ? 44
			je return_false
            mov edi,edi
            push ebp
            mov ebp,esp
            jmp dword ptr [ulIntersectRectRet]

            return_true:
            mov eax,1
            ret 0x0C

			return_false:
			mov eax,0
			ret 0x0C

    } 
}

Make sure to update the addresses.
Then here is the call:

Code:

void FMA(){
		VirtualProtect((LPVOID)ulIntersectRect, 5, PAGE_EXECUTE_READWRITE, &dw_OldProtect);
		Jump(ulIntersectRect, FMA_ASM, 0);
		VirtualProtect((LPVOID)ulIntersectRect, 5, dw_OldProtect, &dw_OldProtect);
}

So then If checkbox is checked then call the FMA function.
If you wanna add the other parts of the godmode you can.
