== Force Feedback ==
Add this to ConfigurationWindowSettings.h:
<big>
#define IDC_NOFF //number
</big>
Add this in typedef enum Integer:
<big>
GF_CT_RMBL
</big>
In Input.cpp, add the following to the Joystick constructor
<big>
ffEffects = NULL;
if(feedBackOFF)
centre = NULL;
</big>
add these in the restore function:
<big>
else{
if(ffEffects){
ffEffects->Download();
}
if(centre){
centre->Download();
centre->Start(1,0);
}
</big>
add this function in:
<big>
void Joystick::updateForce(float factor, double time, int direction){
if(joystick)
{
if (feedBackOFF == 0)
{
if(context->get(GF_CT_RMBL) == 1)
{
if(ffEffects){
ffEffects->Download();
}

// set axes and directions

// if both x & y have FF, make shake come at 45 degree angle
// otherwise just shake the x axis.
//
if (axisIsActive[0] && axisIsActive[1]) {
dif.dwFlags = DIEFF_POLAR | DIEFF_OBJECTOFFSETS;
dif.cAxes = 2;
dir[0] = direction * DI_DEGREES;
}

// create a ramp force

// otherwise just shake the x axis.
//

if (SUCCEEDED(joystick->CreateEffect(GUID_RampForce, &dif,
&ffEffects, NULL))){
ffEffects->Download();// download to driver
ffEffects->Start(INFINITE,0); // infinite so it can be played as many times
}

if(ffEffects){
DWORD DIGFFS_STOPPED1 = 2;
if(!joystick->GetForceFeedbackState(&DIGFFS_STOPPED1))

}
}
}
}
}
</big>
Add this to release:
<big>
if(centre){
centre->Release();
centre = NULL;
}
if(ffEffects){
ffEffects->Release();
ffEffects = NULL;
}
</big>
In UserDialog.cpp:
In the saveUserChoices function, add another bool:
<big>
bool y, z, <b>ff</b>, none;
</big>
<big>
</big>
<big>
</big>
<big>
</big>
