[Sidefx-houdini-list] Animating Boolean Triggers
Thursday, 31 May 2007 Thu, 31 May '07
Not quite sure what you mean. Is this a real-time type of thing where the artist plays the file and hits a "trigger"? If so, you can use the record CHOP. Or are you talking about animating the on/off status of a toggle widget? Or do you mean that everytime someone hits the trigger button, it sets a value to 1 if it was zero and zero if it was one, and adds a key at that frame? If so, I think your callback idea is best, (setting a key on a spare channel for instance). Sean Georg Duemlein, Dipl.-Des. wrote:
Hi, how would one animate 'boolean triggers' in Houdini? I have a OTL that should offer an Trigger (on/off). This results in an animation curve of 1 if the trigger is on and 0 if the trigger is off with contant interpolation. I looks like the 'trigger' interface is not animatable. I thought of having a callback script that generates keyframes and sets the interpolation to constant(). This is sure a funny and educative trip, but maybe I am missing something obvious.
