Thanks! Well that is a very broad question. Perhaps you could let us know what parts you are having trouble with... eg. constructing the bike, what joints to use etc, control method, balancing problems, gameplay concerns, friction issues, level building, score measuring, rendering stuff... etc etc, ...

hm... I set all motor speeds to zero and it was ok. What is the max torque setting, 9999 or something really high right?

umm... how about zero

It comes back to the same answer though... it depends on how much of the screen you want the thing to take up. When an image is attached to a body, scaling the body will cause the image to scale with it. From the JSON you can get information about the image that lets you know where to draw it in rel...

Most of the joints are set to rotate at 1 degree per second, so it will never stay completely still.
To give it more stability I think you would have to make it stand with feet apart a little.

Yea good suggestion, when you don't want duplicates using a std::set makes things easier. It's quite easy for these checks in the contact listener to become complicated. In the top-down car tutorial I started describing something which I hoped would be relatively simple but it still ended up fairly ...

To be honest I'm not really sure what you mean. Could you give an example?

I think the closest thing you could do is to check what impulses were applied by the collision (in the PostSolve function you can get these (eg. http://www.iforce2d.net/b2dtut/sticky-projectiles "Deciding whether to stick") and apply some impulse of your own to try to counteract this, but ...

Yeah, I have that in the feature voting. I thought it would be a close second behind the custom properties, but surprisingly it is quite low. Maybe you are dealing with more complex scenes than others

I don't think there is any easy way to do that right now. This is probably the most necessary feature for Box2D to have in future releases, as I have seen many people asking on the forums about this problem, or similar things that could be solved by allowing each side of the collision to be affected...
