Box2D Forums

Hey guys,

I'm trying to work out if Box2D is the right tool for me. I need to often clone b2World objects - is this straight forward?

Thanks in advance,
Ian

You could try this: http://www.iforce2d.net/b2djson/
This converts to a text representation so it's not really performance oriented.

Hey irresistable force, thanks for replying.

I think I need it faster than that to be honest..

How large is the world, and how often do you need to clone it? Now I'm intrigued by what you're doing here...

I suppose that you need your own function to copy every body. It will be faster that b2JSON because there are will no number-string-number conversions. As far as i remember there are no built-in functions to copy the whole world and even won't be released.
