I used a last touch position+ touch down, to create a clone at the last touch position.
The clones were Solid off,Physics off,Box collide.
On an Ipad 3 i managed to make 200 clones appear onscreen.
I stopped at 200. More clones could have been made.
The code was simple and just had a sprite go to touch location and make a clone.
I tried turning physics on+gravity on+solid on, for the 200 clones.
My Ipad lagged badly. More powerful Ipads could probably do a better job.
(Also the latest update makes projects load twice as fast)
Thank you @Suzzy-Grey ! Yes, we are continuing to work on the optimization of the Ready Maker
