So, I trying to register mouse input, right and left clicks.

The built in fuction didn't seem to work so I took a look at DirectX, but its a little confusing.

Basically, heres what I want:

+ Code Snippet

If(Right Click)
{
Fire Right Hand Gun();
}

Else If(Left Click)
{
Fire Left Hand Gun();
}

/****************************************************************************

#ifndef DIJ_RINGZERO

typedef struct _DIMOUSESTATE {
    LONG    lX;
    LONG    lY;
    LONG    lZ;
    BYTE    rgbButtons[4];
} DIMOUSESTATE, *LPDIMOUSESTATE;

#if DIRECTINPUT_VERSION >= 0x0700
typedef struct _DIMOUSESTATE2 {
    LONG    lX;
    LONG    lY;
    LONG    lZ;
    BYTE    rgbButtons[8];
} DIMOUSESTATE2, *LPDIMOUSESTATE2;
#endif

#define DIMOFS_X        FIELD_OFFSET(DIMOUSESTATE, lX)

#define DIMOFS_BUTTON1 (FIELD_OFFSET(DIMOUSESTATE, rgbButtons) + 1)
#define DIMOFS_BUTTON2 (FIELD_OFFSET(DIMOUSESTATE, rgbButtons) + 2)
#define DIMOFS_BUTTON3 (FIELD_OFFSET(DIMOUSESTATE, rgbButtons) + 3)
#if (DIRECTINPUT_VERSION >= 0x0700)
#define DIMOFS_BUTTON4 (FIELD_OFFSET(DIMOUSESTATE2, rgbButtons) + 4)
#define DIMOFS_BUTTON5 (FIELD_OFFSET(DIMOUSESTATE2, rgbButtons) + 5)

#define DIMOFS_BUTTON7 (FIELD_OFFSET(DIMOUSESTATE2, rgbButtons) + 7)
#endif
#endif /* DIJ_RINGZERO */

change to

+ Code Snippet

if (dbMouseClick() == 2) // right
{
FireRightHandGun();
}

if (dbMouseClick() == 1) // left
{
FireLeftHandGun();
}

if (dbMouseClick() == 3) // left and right
{
FireLeftHandGun();
FireRightHandGun();
}

That should do it. 2 = Right, 1 = Left.

Thanks Guys that worked great.

BTW I'm sorry if I'm asking too many simple questions... I'm still trying to learn.

Your just fine Rei Kumar, thats why we are here haha. You have to start somewhere, and at least you are willing to go the extra mile with C++ rather than with Game Maker where most nub's end up.

Kudos

joo be welcome foo.

You can use a basic timer so it doesn't shoot every frame.

+ Code Snippet

//save the time of the last shot
int last_shot;
//we need a delay time.
int delay_time = 500; //this could be good, its half a second.
//now initialize last_shot
last_shot = dbTimer() - delay_time;

//...
//...
//in the loop

if (dbMouseClick() == 1)
{
if (dbTimer() - last_shot > delay_time)
{
FireLeftHandGun();
}
}

Thats helpful. I was going to set it in the gun class but that might work better.

Of course if you wish to independently use left and right click while allowing for them both to be pressed you should use a bit mask to check for them, i.e. using dbMouseClick() & 0x01, and 0x02. You can do this for the other mouse clicks too.
