  Maybe I'm think wrong? Should I use query AABB method?

  @louis if there are not too many object you can use their position and calculate the distance for them your self, like here:

  If there are many object, you would not want to constantly calculating distance, so it would be better to use queryAABB method

  @ar2rsawseen ,thanks,you rock.
  In my game,maybe have less than 100 sprite, I know this is not a lot,I use queryAABB method,but I wrote not good,so I change to use TNT collision ,it done.
  I will try to use box2d magnets to rewrite it tomorrow.
