apply impulse to btSoftBody

[Dena]

how can I apply an impulse or a force to a softbody?

[Erwin Coumans]

You can use btSoftBody::addForce(const btVector3& force,int node), with node being the vertex where the force is applied to.

For a central force, applied to all vertices, you can use btSoftBody::addForce(const btVector3& force);

Hope this helps,

I made the classic blunder of trying to figure out why none of my forces acted on a falling object (I'm trying to get a helicopter to hover). Imagine my embarassment when I figured out that a force of (0,0,10) will do little to an object of mass 7,500km Newton must be rolling in his grave after I forgot to factor in the mass of the object.

2 hours was a valuable learning experience (trying to figure why bullet wasn't moving the object).
