chops query


Recommended Posts

I've got a pop net feeding specific collision events into CHOPS (in a low particle count, rigid body type thing)

I'm using the numhit attribute which increases as I'd expect but I can't seem to manipulate this value

Ideally I want it to change to 1 when a collision takes place, pause for a few frames then reset to 0 and feed that into a math chop to get the range I want

I've tried trigger/count/logic OPs, coupled with Shift to act as a value reset, but nothing works

Any tips welcome!

me again - I don't think I've been very clear what is happening

in the chop viewpane I get a line indicating "hitid" which is flat form start to finish of the frame range

when the hitid changes during playback (from the POP event) the entire line jumps to a new position - not just at the current frame

I've been trying to get a method to compare the value at frame "$F-1" to value at "$F" (or store the last value and compare that)

anything to give me a spike at my curent frame not a total jump!

the spike seems to occur at frame 1 even when I'm at frame 400 (for instance)

there's gotta be some method _ I tried a global variable that gets reset by an expression chop but that didnt seem to do it either (though maybe my structuring was wrong)

somebody got a suggestion?

thankyou thankyou Jason

its now super funky - you wont believe the time I've spent messing around with this - I'd never have thought of using Record

[because the changes were 'stepping', the end result was the triggered objects were not moving over time, so particles ignored movement between pos a and pos b, when they were meant to be dynamically deflected - now it works]
