Scince january I've had problems with my new colliders, whenever the sled reaches highspeed it just spins out of controll or when I lean backwards the sled shakes vigorously for no apparent reason. I haven't yet found out why it doing so or how I can fix it so I simply don't know how long it will take to fix it get the update out.
Some of you may have seen that I announced that you will be able to make your own maps in 0.3.0 and yes that true, but it isn't a map editor. I've just made a "map loader". Creating maps will only be recommended to advanced users since it takes a fair amount of knowledge. Maps will be made out of a .raw texture a couple of .png textures and some config files. Some may lack the tools to create and edit a .raw image so that is one reason to wait until the map editor is done. Stock maps will be loaded via the map loader so you will be able to study how that works and I will create some documentation on how to make a map too.
A new version of Unity also reasently released with some mayor changes so I'm investegating if it is possible to update to that fairly easy. Unity 5 have made some mayor changes so everything in the game engine is now unlocked so buying the pro version is not nessecery any longer.
Anyway we will have to see if I will need to ditch the new collider or if I will be able to fix the issues I'm having either way it will take a while
