Re: vehicles

There are a number reasons. - instant feedback for player feels easier to control - easy to tune acceleration and max speed - joint torque affects both connected bodies, so the main body of the bike is affected as well, especially noticeable when bike is jumping in the air. This can be minimized by ...

Re: Collision filtering confusion

You need to have an understanding of binary numbers to get how these work. I'm assuming you do, but just for anyone else who comes to this thread in future I'll start from the basics. "Power of two" numbers are the sequence 1, 2, 4, 8, 16, 32, etc... and you can represent any whole number ...

Re: Terrain

Yes probably sometime I will. Ray Wenderlich has a pretty good tutorial about that, you could check that one out. I think he uses polygons whereas I would prefer chain shapes though, because they do not have the sticking in the ground problem, and you can easily make concave shapes. I think the typi...

Re: Incorrect size of images displayed on editor

Images will start with a scale of 1, which means that their vertical side is 1 unit high in the physics world - if this is what's happening it's not a bug. See the tutorial video 14 for more info: http://www.youtube.com/watch?v=wwEPKhdzIpk If something else is happening maybe you could show an examp...

Re: Too many custom properties

Yeah... bitflags are great for speed, but speed is not the requirement here. I was thinking about this some more, and had another idea. How about if you could write a little script function for each item class to customize which properties are shown. The function would take an instance of an item, a...

Re: Too many custom properties

hmm... interesting. Just to make sure I understand what you mean... for example you might have broad categories for bodies like plants and animals. The animals should have properties like number of legs, and the plants should have something like color of flowers, but the plants don't have legs and t...
