add displacement according to their coordinate

Asked by 张文卿

At the begining of each time step, I want to add displacement to every particle according to their center coordinate.
just like this:for x direction，Displacement=a*x*timestep.
a is just a coefficient.
But I only find 'addMove'.Is there any way solve this problem.Thanks: )

You can prescribe velocity such that during next time step the particle
gets to desired position

b.state.vel = (desiredPos - b.state.pos) / O.dt
