hello,everyone
i'd like to use dopnumrecords funtion to calculate the number of impacts.
i don't know what' s going on with my work. when ball collide with the box just one time,but the number of impacts records are more than one .anyone can give me suggestions ,thank you very much.

Hi,

The impact recorder works for all the substeps of the frame. Also, I believe it will record the impact of every piece of the object that collides for each substep.

A trick to use is, simply see if there's just a impact of any sort on a perframe basis per object.

still a little confused, anyway thank you for your reply

Impacts are calculated per geometry not per object. You see one collision but in fact there are four SDF intersections (could be more or less) and this is what DOPs shows you in Detail View.

If you are interested in counting how many times a ball bounced at the ground, you can post-process your data in CHOPS (for example clamping channel to one and then using Area to measure number of hits.


cheers,
sy.
