How to follow the path of a particle in DPM?

I want to write a UDF, that, when there is an impact on a wall, the coordinates of the centroids in the particle path which made that impact are shown.
Do you know how to loop over particle path in a DEFINE_ON_DEMAND? And how to retrieve the particle ID of each path?
Thanks for helping.

You ask for a solution using DEFINE_ON_DEMAND, but I would instead use DEFINE_DPM_BC (or maybe DEFINE_DPM_SCALAR_UPDATE, depending on what you exactly want).
In that case, p is the pointer to the particle, p->part_id is the ID and P_POS(p) is the position of the particle.
If with "centroid" you mean the center of the face on which the particle collided, you would access it using the "f" in the DEFINE_DPM_BC macro, and then F_CENTROID(x,f,t) would set the centroid of that face to variable x.
