Hi there,
I'm using ODE to give me collision and physics for a 2d set of =
games. I've got it all hooked up and working, so far, using this =
methodology:
I have 2 'glass sheets', which are frictionless, and a fraction over 0.5 =
units apart. These are used to constrain movement along the Z direction.
But I'm getting odd...artifacts. For instance, when I join 2 objects =
together during the simulation, they are fine for a moment, then wobble, =
and then teleport in what appears to be a single frame to the top left =
of the screen.
So, my question is - is there a better way to simulate 2d physics using =
ODE? I thought of resetting every object's Z coordinates and Y rotation =
to 0 every frame, but I'm loathe to actually fiddle with the simulation =
- unless I have to.
Feedback and thoughts welcome!
