So …with @Bubble 's assistance, I have produced an extension and behaviour called ‘Cos Wobble’ for wobbling/shaking/vibrating/oscillating stuff!
Here’s an example project with it attached
what thinketh thee to the above?
I’ve done a bit more work on the example project and added sliders
I do not understand it at all! BUT I LOVE IT 
Is there a behind the scenes of how it works?
(I know it’s an extension, just wondering if you could give a quick summary 
)
When a number changes within cos or sin the value oscillates (i’ve invented numerous ways of spelling this!) between -1 and 1 and so i’m changing the x,y and angle using that and using lerp
Is this the sort of thing others might want to use? I think it should be less process hungry than the shake behaviour
If you look at my dev thread there’s a sort of over view of how and why this works
I’ve done a bit more work on the example project and added sliders
so - any comments!?
Wow it’s even better than I thought it would be, love it!
oooo…set all the sliders to full and there’s two birds flying around each other!
