In the example, the particles are created at the center of the shape that is hit, but not at the place where it is actually hit, for example: as you can see here it is created at the center of it
if i were to use the same method as in here it would just create the particle at the center of the wall, inside it. I want the car to have “scrapes” particles AT the hit position of the car itself and the wall, not at the center of it.
