Well to play some of my computer games I plug in my PS3 controller then use some six-axis program so my computer can recognize it. Since it works it means I should be able to do it too. So my question is: How do I get input from the controller?

You could try using IDirectInput8::EnumDevices to see if DirectInput can see the device, although I don't really know if that'll work. Give it a go I guess...

Thanks for you help Evil Steve. It can recognize it. I did some more researching and I was able to get something working.

I can get it to check correctly if a button is pressed.

But I am having problems with the sticks.

js.lX is supposed to be the X direction of the stick. However when I check the results it shows that it is some big number.

Shouldn't it be like 0 until I move it?

What am I doing wrong?

Sorry for the bump but I'm back after a lot of homework and being sick. I never got it to work though.

This is the code I'm using.

I made a class for it. These are the only two calls I make. I get input then I write the result to a file. (ignore the getX(). Its just a temp name for it)

ps3i->getInput();
out << ps3i->getX() << endl;

The getInput() function

void PS3Input::getInput()
{
PS3Device->Poll();
PS3Device->Acquire();
PS3Device->GetDeviceState(sizeof(DIJOYSTATE2), &js);
}

getX()

int PS3Input::getX()
{
return js.lX;
}

This is the enumObjectsCallback function

BOOL CALLBACK PS3Input::enumObjectsCallback( const DIDEVICEOBJECTINSTANCE* instance, VOID* context )
{
HWND hDlg = ( HWND )context;

static int nSliderCount = 0; // Number of returned slider controls
static int nPOVCount = 0; // Number of returned POV controls

// For axes that are returned, set the DIPROP_RANGE property for the
// enumerated axis in order to scale min/max values.
if( instance->dwType & DIDFT_AXIS )
{
DIPROPRANGE diprg;
diprg.diph.dwSize = sizeof( DIPROPRANGE );
diprg.diph.dwHeaderSize = sizeof( DIPROPHEADER );
diprg.diph.dwHow = DIPH_BYID;
diprg.diph.dwObj = instance->dwType; // Specify the enumerated axis
diprg.lMin = -1000;
diprg.lMax = +1000;

// Set the range for the axis
if( FAILED( PS3Device->SetProperty( DIPROP_RANGE, &diprg.diph ) ) )
return DIENUM_STOP;
}
}


Wasn't I supposed to get values from -1000 to 1000?

These are the ones I get.

Looks right to me.
Subtract MAXWORD/2 (eg, the maximum value of a 16 bit unsigned integer, divided on two).

Being unsigned, it cannot represent negative numbers :)
What did you do when the value was 32768? was it perhaps idle? (hint hint)

When I change it to: return (js.lX-(MAXWORD/2));
Now the value I get for no movement is -512

If it can't represent - numbers why set the range from -1000->1000?

Yes it was idle. Now instead of 32768 I get -512





From what I can understand aren't I supposed to just set a range

-5 to 5

Then for example if I wanted to move a char with it then I just get the value (ex: 5) and use that as the speed, correct?

So what's with all these large and strange numbers?

MAXWORD = 0xffff = 65535.
MAXWORD/2 = 32767
32768 - 32767 = 1, which is 0.1% above 0.

Where are you getting -512 from?

I have no idea but it seems to random.....

These numbers are from starting it then holding the left stick up. I waited a few seconds before moving the stick.

These numbers are from when I tried it but did not touch the controller at all...

[Numbers too long, it pissed me off, deleted.]

And these from when I changed it back to: return js.lX;

[Numbers too long, it pissed me off, deleted.]

And these from when I waited then moved the left stick to the left.

Whats with all the random numbers? Shouldn't idle be a constant?
