Using surface velocity to move bodies

[Night Elf]

As suggested in this topic: http://www.slembcke.net/forums/viewtopi ... form#p1532, I'm trying to move a body through the surface_v property. I've tried assigning a value to the surface_v of the ground and also to the surface_v of the body's shape, but none of them produce any results. Can you help me make this work?

Have you set any friction? Surface velocities only affect friction calculations.

Ah! So, both bodies need to have at least some friction. Thank you very much, it's working now!

Yep. I chose to multiply the friction and elasticity values together to get the final value used in the calculations. It seems to make the most sense to do it that way to me, but unfortunately I don't think that there is a "correct" way to do it.
