Amazing! Thank you so much guys, these are both an enormous help! (and so simple/logical after all - you should have seen the mess of nodes I was finding myself in yesterday)
So, my python is pretty much non existent but, if I understand correctly, both solutions work the same. By taking the current value, adding a constant multiplied by a variable, and then repeating the calculation on next frame and so on? And Delta, in the xpresso one, is just a way of having the setup adjust correctly with different fps?
Soooo elegant! Thanks! 🤘🤘🤘
