   Hi,
   I am currently using actions to manage some movement in my game, like falling objects.
   But as i am adding more and more different movement, i am wondering if it would not be easier to let chimpmunk handle movements for me.
   I am currently using NSCoder to save the game in case the player quit. How can i do to save and retore physic body in movement (like falling objects) ?
   I ask before i change my code, because i don't want to change everything and get stuck at the end...

   Thanks

   This is a very good question... A piece of cake is to save all your custom data from a game, but how to save the physics engine state...?

   Well, I'm not very gifted in chipmunk (never even used it) but I was working on a level editor and what I did regarding box2d was to save all the data I found I would need in a xml file. I saved stuff like size, mass, position, velocity, etc... Then I would 'just' load the stuff from file and create the objects in box2d.

   Not easy, to be honest, but it worked very well.

   I guess that unless the chipmunk world has a saveToFile and a loadFromFile kind of method... you're on your own.

   You have to save all stuff yourself. There is no SaveAll function.

   I would just save the most import things, like positions and start the simulation from that state after loading. Should be ok, if you do not have very high velocities.

   Thanks you :) ! I will do as you said both, save position and force, and restore them, that should work well :)

   Thanks again !
