Warning: Enumeration values not handled in switch

Monkey Targets Forums/iOS/Warning: Enumeration values not handled in switch

Hi forum,

I'm fairly new at monkeycode and so far I'm impressed - I don't come from a game developer background, but Monkeycode just makes perfect sense. Also, all target platforms I tested so far look identical, which is fantastic!

Here's my first little issue, though. For the iOS target I just upgraded to XCode 4.2 / iOS5, the Monkey project is built with version 47c. I now get a warning when I build/run the project with both Monkey and XCode:

"Warning: Enumeration values 'UITouchPhaseMoved' and 'UITouchPhaseStationary' not handled in switch"

This refers to the line "switch( [touch phase] ){" in the gxtkInput::OnEvent() in main.mm (see further below).

I also notice that a multi-touch gesture that used to work before doesn't work any more. Single-touch gestures still work fine. The only touch index that is registered is index 0.

Looking at the code block below I think the touch index issue could be related to the warning.

Did anyone come across that issue?

void gxtkInput::OnEvent( UIEvent *event ){
       if( [event type]==UIEventTypeTouches ){

               UIView *view=app->appDelegate->view;

               float scaleFactor=1.0f;
               if( [view respondsToSelector:@selector(contentScaleFactor)] ){
                       scaleFactor=[view contentScaleFactor];
               }

               for( UITouch *touch in [event touchesForView:view] ){

                       int pid;
                       for( pid=0;pid<32 && touches[pid]!=touch;++pid ) {}

                       switch( [touch phase] ){
                       case UITouchPhaseBegan:
                               if( pid!=32 ){ pid=32;break; }
                               for( pid=0;pid<32 && touches[pid];++pid ){}
                               if( pid==32 ) break;
                               touches[pid]=touch;
                               keyStates[KEY_TOUCH0+pid]=0x101;
                               break;
                       case UITouchPhaseEnded:
                       case UITouchPhaseCancelled:
                               if( pid==32 ) break;
                               touches[pid]=0;
                               keyStates[KEY_TOUCH0+pid]=0;
                               break;
                       }
                       if( pid==32 ){
                               printf( "***** GXTK Touch Error *****\n" );fflush( stdout );
                               continue;
                       }

                       CGPoint p=[touch locationInView:view];
                       p.x*=scaleFactor;
                       p.y*=scaleFactor;

                       touchX[pid]=p.x;
                       touchY[pid]=p.y;
               }
       }
}

The code above comes straight from MonkeyPro/modules/native/mojo.ios.cpp and is part of main.mm

Cheers!

OK, this was partly a real Monkeycode beginner's issue. Multi-touch gestures worked again once I deleted the previous iOS build...

Still, XCode 4.2/iOS5 complains and issues the warning in my previous post. It would help to add UITouchPhaseMoved and UITouchPhaseStationery or a "default:" to the switch in modules/native/mojo.ios.cpp (see my post above)

Currently any build of any project creates the warning in iOS.
