Thanks for sharing :slight_smile:
I just checked my game Quadro! and it’s still working but i will update XTLayer with your code :slight_smile:

I did not actually use the XTLayer, so I didn’t update the class itself, but I thought I would put this out there for anyone else where this suddenly stopped working.

I’ve written a simple gestures extention for cclayer.
At the moment swipe, tap and double tap are working :slight_smile:
For those interested or looking for a class like this, i have attached it to this message.

Hi Edwin,

Just wondering if you are going to add any “pinch” functionality and maybe any scrolling left to right, up/down, etc.

Thinking like how you can scroll with one finger on ios devices.

HI… i have touches not in a layer but in my hero sprite class by doing CCDirector::sharedDirector()->getTouchDispatcher()->addStandardDelegate(this, 0); . So, I have CCtouchesBegan, Moved and ended functions in the hero class and it works fine. If I have to make this XTLayer work what I would have to do extra to make it work. All the layer class have XTLayer as base class. thx.

#27

Well using XTLayer this means that the layer will receive the touch events. Not your sprite. It is also not a great idea to have these events on a sprite. Your layer should always be doing this work. At least under any circumstance that I can think of right now. There was some discussion about this a while back, search the forums a bit.

#28

i solved it by copying all the relevent functions and variables from XTLayer onto my player class and works fine now… i am just working how to figure out multi touch with it… seems to working fine… thanks

#29

This is wrong behavior though.

#30

why so? cos it might clash with other layer delegates??

#31

well you are not subclassing correctly, either.

#32

Has anyone updated this for V3 alpha yet?

#33 
long Game::millisecondNow()
 {
     struct cc_timeval now;
     CCTime::gettimeofdayCocos2d(&now, NULL);
    return (now.tv_sec * 1000 + now.tv_usec / 1000);
 }

This code can be overflowed. It must be fixed like below.

long long Game::millisecondNow()
 {
     struct cc_timeval now;
     CCTime::gettimeofdayCocos2d(&now, NULL);
    return (now.tv_sec * (long long) 1000 + (long long) now.tv_usec / 1000);
 }
#34

Any fixes for XTLayer to work on 3.0rc0?

#35

Thanks for the share.

#36

I have updated class for v3. If anyone need for it here is the file:

XTLayer_v3.zip (3.6 KB)

When i compile the code then gets the 2 error for both schedule_selector
this->schedule(schedule_selector(XTLayer::tapHandler), (this->_xtDoubleTapTime / 1000), 1, 0);
and
this->unschedule(schedule_selector(XTLayer::tapHandler));

Error 1 error C2440: ‘type cast’ : cannot convert from ‘void (__thiscall XTLayer::* )(cocos2d::CCObject *)’ to ‘cocos2d::SEL_SCHEDULE’

Error 2 error C2440: ‘type cast’ : cannot convert from ‘void (__thiscall XTLayer::* )(cocos2d::CCObject *)’ to ‘cocos2d::SEL_SCHEDULE’

Thanks in advance for any Help

This is great. Thank You.

But, can you explain how to detect long touch ?
I try this code and what I find is : if you touch the layer long enough, the xtLongTapGesture function will called when touch ended. Its a long press isn’t it? but what about a long touch ?

I want to call xtLongTapGesture function continiously as long as the layer touched.
Can we do that?

Thx

[Edited]

I have found the solution. You just have to use Action on this.
thx
