velocity expression leaves falling problem
hello forum
I’m animating some leaves falling. They are linked to branches via parenting so they grow as the branches grow. I have them rotating as they fall but need to wiggle there anchor points to give them a swirling motion. I originally wrote this
\
if (position[1] < 500 ) wiggle(thisComp.layer("ca08").scale[0],thisComp.layer("ca08").scale[1]) else anchorPoint \\ so that when the leaves hit the floor, they would stop swirling, because of parenting all 100 leaves have differring base positions, nightmare. If I replaced // position[1] < 500// with //velocity < 0 // then they would cease swirling when stationary. Or maybe I could calculate their global or comp position , is there a way of doing this for 2d objects? Thanks John Brown The Popular Society -

I’m not sure if these are what you’re after, but
toWorld(anchorPoint)[1]
gives you the global y position and
position.speed
gives you the scalar value of the velocity

Thanks for that, calculating the speed worked, the leaves anchor points moved as the velocity increased .The only problem is my “else anchorPoint” line which makes the leaves “snap” back to their normal position, But this gives it a traditional “Lotto Reiniger” feel anyway,
thankyou very much Dan.

So what was the final outcome of this?
