[Source]Simple menu class

[Void]

Uhg, not much to say, I made a simple menu class this morning for myself to use since I don't like everyone else's.

The function's name speak for themselves, except for InitControls. To initiate the hotkeys for the menu, just put InitControls in a loop and create a seperate thread for it.

[highlight=cpp]
void MainThread()
{
while(true)
{
MenuInstance->InitControls();
}
}

....

CreateThread(0,0,(LPTHREAD_START_ROUTINE)MainThrea d,0,0,0);

That's the only seemingly confusing part. Use the menu item's index to get it's current status ( on/off ). When your module detaches I made a function to release the classes private members so you don't get leaks.

Here we go.

Menu.h:
[highlight=cpp]
#ifndef MENU_H
#define MENU_H

#include <windows.h>
#include <d3d9.h>
#include <d3dx9.h>

struct MenuItem {
int index;
char* text;
bool status;
MenuItem* pNext;
};

class cMenu {
private:
IDirect3DDevice9* m_pDevice;
ID3DXFont* m_pFont;
MenuItem* MenuItems;
int CurrSelected;
int m_nItems;

public:
cMenu(IDirect3DDevice9*,ID3DXFont*);
void Update(IDirect3DDevice9*,ID3DXFont*);

void AddItem(char*,int);
void RenderMenu(void);
void InitControls(void);
void Release(void);
bool GetStatus(int);
};

#endif

Menu.cpp
[highlight=cpp]
#include "Menu.h"

cMenu::m_nItems = 0;

cMenu::m_pDevice = pDevice;
cMenu::m_pFont = pFont;

void cMenu::AddItem(char *text, int index)
{

Also.. I made a small example just in case you guys can't figure out how to use it.. The whole project is the attached file below.

YOU SUCK. YOU SUCK. first post. love you david

[Auxilium]

Looks gewd. Won't use however because im still learning C++

[Void]

Ohai there Patrick. The thanks button is waiting to be pressed. |:

[Auxilium]

Pressed

['Bruno]

wow... Attachments Pending Approval? fail... C++ section now needs approval

Nice david ;d anyway i wouldn't expect a different result from ya =D unfortunately i don't know much (anything) about D3D to comment that much.

=o im surprised that someone used it lulz

It's just a class..

Hey Void, does unlocking the cursor mid-game (eg, while you're in game killing people / re-spawning) allow mouse co-ordinates other than center to be grabbed?

(I don't have the game, so I can't find out - I have 1GB internet per month, and Combat Arms is well... rather large)
