Field Force (follow a curve)
-
Hello Dr. Sassi,
Hope you're well.
I have a very simple scene here: https://www.dropbox.com/t/fpztcYwh1jJBYo1S
What I'm trying to do is make the ball follow more closely the curve using "Add to Velocity".
I like the idea of controlling dynamic simulations with field forces with the "Add to Velocity" type, but I'm struggling to understand how to make it follow the force more closely.
Thank you,

Hi Robert,
Not to be lazy, but Jonas made a nice and clever short instruction on that theme.

A mix is needed to balance the effect of centrifugal forces. I used the term balance on purpose here.Enjoy.

Thank you! That is using the "Change Direction" force type. Are you suggesting using a mix of "Add to Velocity" and the "Change Direction" field types with two separate field forces?
I'm keen to figure this out using "Add to Velocity" instead of "Change Direction" to allow for more flexibility and more natural motion.

Hi Robert,
Please have a look here. Since the ball had no velocity, I used Absolute velocity first. The particles are more of an additional test, not needed.
