Cocos2d iPhone v3.0: deslizar hacia arriba para realizar una acción

Question

Tengo algunos problemas con la configuración de toques para deslizar hacia arriba para realizar una acción.Estoy intentando utilizar el código siguiente, pero no reconoce los toques.

-(void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
NSSet *allTouches = [event allTouches];
UITouch * touch = [[allTouches allObjects] objectAtIndex:0];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];

//Swipe Detection Part 1
firstTouch = location;

    CCLOG(@"touched");
}

-(void) ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
NSSet *allTouches = [event allTouches];
UITouch * touch = [[allTouches allObjects] objectAtIndex:0];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];


//Swipe Detection Part 2
lastTouch = location;

//Minimum length of the swipe
float swipeLength = ccpDistance(firstTouch, lastTouch);


CCActionJumpTo *jump1 = [CCActionJumpTo actionWithDuration:2 position:ccp(self.contentSize.width*.4,self.contentSize.height*.1) height:self.contentSize.height*.5 jumps:1];
[_fufunaken runAction:[CCActionRepeat actionWithAction:jump1 times:1]];


//Check if the swipe is an up swipe and long enough
if (firstTouch.y > lastTouch.y && swipeLength > 60) {
    [_fufunaken runAction:[CCActionRepeatForever actionWithAction:jump1]];
}

}

Ni siquiera dice "tocado" cuando toco la pantalla y tengo habilitadas las interacciones del usuario en init.¡Cualquier ayuda será apreciada!

En cocos2d v3 necesitas reemplazar todo ccTouchesBegan/ccTouchesMoved/ccTouchesEnded a

-(void)touchBegan:(UITouch *)touch withEvent:(UIEvent *)event
-(void) touchMoved:(UITouch *)touch withEvent:(UIEvent *)event
-(void) touchEnded:(UITouch *)touch withEvent:(UIEvent *)event

La buena noticia es que puedes obtener la ubicación actual del toque simplemente usando la siguiente línea

CGPoint touchPos = [touch locationInNode:self];

Por lo tanto, todo esto no es necesario.

/*
NSSet *allTouches = [event allTouches];
UITouch * touch = [[allTouches allObjects] objectAtIndex:0];
CGPoint location = [touch locationInView: [touch view]];
location = [[CCDirector sharedDirector] convertToGL:location];
*/
