glyph Posted August 21, 2003 Share Posted August 21, 2003 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!

glyph Posted August 22, 2003 Author Share Posted August 22, 2003 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?

Jason Posted August 22, 2003 Share Posted August 22, 2003 i think you might find that you have to Record CHOP the entire simulation in order to modify it. Quote Link to comment Share on other sites More sharing options...
glyph Posted August 22, 2003 Author Share Posted August 22, 2003 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] mark Quote Link to comment Share on other sites More sharing options...
