Hello,
I have a CCLayer with a CCMenu. This CCMenu has a bunch of CCMenuItems. I move the CCLayer when swiping the screen. The problem comes when I try to swipe the screen when there is a CCMenuItem. Instead of moving the screen, it activates the touch selector action. Any ideas on how I can avoid this?
Below is a video to make things clearer :D

If you make the layer a targeted touch delegate with top priority and let it swallow all touches, the buttons won't be activated. Then you can include checking for button touches in the layer's touch methods, and activate the button when it's being tapped but not while swiping. So in CCTouchMoved you would check if the button isn't touched anymore and if so, start swiping instead. Then you can also make sure it doesn't activate any buttons during a swipe, i.e. as soon as a swipe has started it should stop looking for buttons being touched.
Hi Scryb,
Thanks for you reply.
The layer has this touch priority:
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:1 swallowsTouches:YES];
In the layer's touch methods ( -(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event { ) how would I check if a CCMenu has been touched?
To deactivate touch for the CCMenu I would use menu.isTouchEnabled = NO;?
Thanks again!
You should set it to INT_MIN+1, not 1, if you want it to swallow all the touches.
BOOL buttonTouched;
-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
buttonTouched = [self.menu ccTouchBegan:touch withEvent:event];
return YES;
}
-(void) ccTouchEnded:(UITouch *)touch withEvent:(UIEvent *)event
{
if(buttonTouched) [self.menu ccTouchEnded:touch withEvent:event];
}
-(void) ccTouchCancelled:(UITouch *)touch withEvent:(UIEvent *)event
{
if(buttonTouched) [self.menu ccTouchCancelled:touch withEvent:event];
}
-(void) ccTouchMoved:(UITouch *)touch withEvent:(UIEvent *)event
{
if(buttonTouched) [self.menu ccTouchMoved:touch withEvent:event];
}
- (void)registerWithTouchDispatcher {
[[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:INT_MIN+1 swallowsTouches:YES];
}This is of course assuming you have a CCMenu *menu set up with a property to access self.menu in those methods. You would then have to put your own swiping code in here, and do whatever you need to get the behavior you want.
To deactivate a menu item, you call [item setIsEnabled:NO]. You can supply an inactive state sprite for CCMenuItemSprite to show the player that the button is not working right now.
Hello,
Thanks for the replies, I'll try both solutions and let you know!
