collision help wasted alot of time

[teamb]

question to the project.
1: how do i maybe add force so when his walking sidewards or running or what ever the particles should have force just like the video so the ground screws go flying out of the way?

Question non related
1: in future how do i check if particles are colliding with body,like indication it is being hit. i seen colors change once objected is selected in phsx collision is that it ? is this how you know its being hit

1) If you mean "inheritance", so particles inherit the movement of the character, that is already applied through spawn operator. You can increase inheritance from 100 to larger number to make it even stronger (or reduce gravity on PhysX). 
Keep in mind that PhysX here skips some of the particles collisions, because character is moving pretty fast, but if you lower the time step in Tyflow icon, to 1/2, or 1/4 or more, the collision will be much more precise, but at the same way, much more "explosive", because of more collisions. 

2) If you want to change color on collision screws with body mesh, just add another event (with different display color), and connect it to the PhysX collision. In that second event also copy paste previous PhysX collision operator (because I assume you want them to continue colliding with the mesh). 
You can also turn on "inter particle collision", if you want to send them to new event after particles collides with each other.

hi kindly watch this video. the frames steps i did not test yet but how come the nails arnt flying away as he moves off or moves into
