Problem with multi-touch in 3D space Empty Problem with multi-touch in 3D space

If I use tutorial05 and place the following code below in templateScreenTap(), it works fine when I press the display with 2 fingers

Code:
void templateScreenTap( void *_ptr, unsigned char _state )
{
   if (sio2->_SIO2window->n_touch > 1)
   {
      printf("\nMulti-touch is working...\n" );
   }
...
...

If I place the same code with tutorial14, the printf() will never get executed when I press with 2 fingers (I verified by stepping in with gdb)

The only difference I see is that in tutorial05, it is in 2D space pretty much all the time.

Any idea why multi-touch does not trigger in 3D space as I tried with tutorial14?

Thanks

Make sure that you enable multi-touch:

[ self setMultipleTouchEnabled:YES ];

Check tutorial05 for more info...

Dang - I feel so stupid. Thanks man.

I was using tutorial13_1 to emulate touch on the device for my app and of course it was working as it is enabled in tutorial13_1 ;-)
