Returns the velocity that a point at a location in simulation space would have if it were attached to a DOP object.
dopvelatpos(dop, objectSpec, posx, posy, posz,
This velocity calculation takes into account the velocity and angular velocity of the simulation object as stored in its Position data.
Setting the usevolumevelocity argument to a non-zero value causes the returned velocity to be affected by a geometry space velocity calculated from changes in the volumetric representation of the geometry.
Setting the usepointvelocity argument to a non-zero value causes the returned velocity to be affected by the velocity attribute on the geometry for the object. The geometry velocity attribute is added to the result as a geometry space velocity which is added to the velocity from the Position data. If both usedsdfvelocity and usepointvelocity are non-zero, then the sdf velocity is used, not the point velocity.
dopvelatpos("/obj/dopnet1", "obj0", point("/obj/dopnet1:obj0/Geometry", 0, "P", 0), point("/obj/dopnet1:obj0/Geometry", 0, "P", 1), point("/obj/dopnet1:obj0/Geometry", 0, "P", 2), 1, 0)
Returns the simulation space velocity of point 0 of the geometry attached to obj0, taking into account any velocity attribute on the geometry.
