I am right now developing game similar to Cut The Rope.
But I have some problem in developing this game. I have successfully created rope and attached multiple rope with candy.
Below I represent where the problem occur. I have created rope in strict vertical fashion. Suppose I have three rope in game play, one is position on left side of the screen, second on middle and third is on right side of the screen. I place candy at below the first left side rope.
One end of the rope is attached with bolt and from this point rope is constructed and on the other end candy is going to attach.
First rope contain 10 segment, second contain 20 and third contain 40 segments in rope. First rope directly attach with candy body and it works good but the performance of other two rope was not good. Because other two rope need time to reach at candy body.
So rope joints take time to attach itself with candy body. So rope is destructed from the middle or at any position based on the size of the rope. After some time say 2 seconds all the joints attached correctly with the candy and behavior become perfect but initialization was not good.
From other source I found that I have to increase the physics update time for some moment to make it normal. After that update physics set to normal.
All the three rope and candy have dynamic body. I properly set category and mask bit for it. Please some intelligent person give some guidance.
