Hey guys,
So i’m trying ot use sines and cosines to make an image bounce (like a small ball bouncing up and down at regular intervals) But i cant seem to control the time well. What im looking is for the image ot bounce once every 1-2 seconds, no more than two or three x positions up and down. But i cant seem to get anything more than once a minute- is it because im using #DWFSS#?
Is there a good expression to use specifically for this kind of movement?
Yes, put simply the tag #DWFSS# provides rotation of 0…359° over 60 seconds (a minute).
If you want to try to solve this yourself, start with #DWFSS#*2 (then with #DWFSS#*4) …
If you want to see sin(rad( x )) for circular and ellipsoid movement, check out this tutorial:
Including my demo:
Then move on to ‘bounce decay’ and rotation (for bouncing object):
ball.translateX = time * 5
ball.translateY = 6 * abs(sin(time*3))
Hi @celes.meh, great question and thanks for recomendation from @Facer_Official 
This guy in your animated gif looks almost like me except the hairs
Anyway, I do think that the answer (another approach as @andrew.dowden describe) could help some more designers. Therefore I will prepare in minutes a new TOMAJA Micro Tutorial and post a Link here too.
Stay tuned 
SO i used your tutorial and ended up with about #DWFSS#*65, It turns out i hadnt gone high enough before! that said i also really liked @Tomas solution- Thank you so much for your help!!
AMAZING micro tutorial! thank you!
Happy to assist …
I played around after reviewing the @Tomas tutorial. Specifically, I used abs(sin(rad( x ))) for a fixed ground plane.
Let me know if you need anything else …
Thank you so much! I just finished the face i was working on where i wanted to use this!
Any chance you could turn on inspection mode? Thanks!
Can do! sorry im on vacation so ive been snorkeling all morning!
done!
Sorry, it wasn’t ‘finished’. And, I was still pondering adding decay …
Inspection enabled.
