Hello,
I've been wanting to try to integrate ODE into an engine for a =
while, and just started messing around with it tonight. All of the =
collision and response is working great, but I can't seem to figure out =
one thing - how can I apply force to a body in the world to "push" it in =
a direction? I've gone through the mailing list and tried a million and =
one different ways, but I can't seem to get the object to move.
Specifically, I have a box object which is already at rest in the =
world and I just want to push it up into the air (i.e., throw it).
dBodyAddForce seems to have some (but VERY little) effect on the =
body when it is in the air (it just bounces a little more when it =
lands), but once it's landed on my ground plane, it has no visible =
effect on the body whatsoever.
Any ideas?
Thanks,
Nathan Ostgard
