Physics in Snowboard game

Solar2D General Questions/Discussion
#1

Hi,
I am trying to develop a 2d Snowboarding game using physics with corona. For the board i just created a roundedRect.
With some Rects linked together i created basic ramps and hills. If I a apply some Linear Velocity to the board it slides over these obstacles.
The problem ist that from time to time the board gets stucked . It seems to collide with some pixels of the ground or something and so suddenly stops. Does anyone has a solution ? I also tried with different values for friction.
Only a circle object slides fluid above the obstacles but not all sorts of rounded or not rounded rects / polygons.

Are you sure that all your polygons are defined clockwise? That can cause such an issue. [import]uid: 159908 topic_id: 34220 reply_id: 136062[/import]

If your ramps have bits that stick up and a corner of an object sliding, it will catch. Are you using hybrid draw mode to see where it’s catching?
