Hi all. You need to create a machine (like in hill climb racing), decided to choose the box2d physics engine. But there were a lot of questions that I do not know where to ask at the office. forum silence, a new message appears once a month and no response on other forums too, no movement. Tell me where you can get answers to questions (not off. documentation, to sense from it a little). Or what is now the most popular physics engine in js, where a large and active community?
