   Hello everyone,

   I am very new to Cocos2d so please be gentle. I know there are hundreds of posts about this subject and most of them indicate that one should look into the "Touches Dispatcher". I understand that this dispatcher can implement the "standard" method or a "targeted" method by which individual nodes register and receive touch events via ccTouchBegan and the like...

   While I have no problem with this, I am trying to implement code by which individual sprites can be multi-touched for purposes of rotate, translate and scale. Several posts have indicated that pinching and rotating are not supported via targeted dispatch and that one should pursue the standard dispatch methods if pinching and rotating need to be supported.

   So my question is... When using the standard dispatch, how does one determine which sprite has received the touch?

   Thanks for any guidance here.

   Thanks Joethemonkey,

   However I am not sure that this explains how to tell which sprite was touched (it seems to only show how to get all touches and events globally without explaining how to determine which sprite was touched).

   i am too confused that how to detect whether a specific sprite is touched or not?
   i tired this but i dont get proper touch detection

   int xdiff=(int)(exit_spr.position.x-location.x);
   int ydiff=(int)(exit_spr.position.y-location.y);
   if ((abs(xdiff) <= sprite_scaleX/2 )&& (abs(ydiff)<= sprite_scaleY/2) )

   where am i wrong?
