Help Spinner in FP questions

If xBAM_BAll.Speed = 500 (just an example)
SpL.angularDamping = 0.30 - (2*(xBAM_Ball.Speed -300)/10000))
So
SpL.angularDamping = 0.30 - (2*(500 -300)/10000))
SpL.angularDamping = 0.30 - (2*200)/10000))
SpL.angularDamping = 0.30 - (2*200)/10000))
SpL.angularDamping = 0.30 - (400)/10000))
SpL.angularDamping = 0.30 - 0.4
SpL.angularDamping = 0.26
OK... The idea: the more the ball have the speed, the less will be the angular damping.
You can use a lot of others formulas or criteria.

JP,

The 0.4 in your example should be 0.04. That makes your final result correct. I am guessing you must have tried many formulas before using this one.

Not really a lot of formula and I think this one is not the best...
Typo corrected (0.4 -> 0.04)

The only thing I can suggest that might make it better is to set up a test table that has a kicker aimed at a spinner. You would need to know your minimum and maximum ball speed that is possible on the table. Then set the kicker strength to fire the ball at the minimum ball speed. Then find the best Angular Damping setting that does what you want. Then repeat the same process with the maximum ball speed. Then you would need to figure out a formula that ramps the Angular Damping setting between the two settings.

As it stands, you could delete the times 2 in your formula and substitute 5,000 for the 10,000 and you get the same answer.

Sorry for the question, if angular dampening slows down the spinner's rotations, why decrease them when the ball is faster? I don't understand the purpose of this.

 

[Popotte]

If the ball is fast, the spinner have to rotate a lot. And as it's angular damping wich slow the spinner, angular damping are to be low.
Angular damping slows the rotation.

Ok, so I missed something in my thread where you and rav were talking about angular damping, and yet I read the context of angular damping several times....
So it must be low, I thought the opposite, yet in my tests it works very well, I almost manage to make it stop as I thought, because my final goal is to prevent the spinner from stopping horizontally.
Your code in Hotip, is very laborious, you modify the "angular damping" in many phases, I have a doubt about the reason for a trigger, but a question, the values you set, on what basis did you orient yourself?
Did you know that depending on how you set the "damping" in the editor, the initial value found in the xml also changes?

PS:I'm waiting for your reply to my email from a few days ago.

The trigger is just for initialising AngularDamping depending of the speed of the ball and not by the value in the .xml. You can hit the spinner many times, so have different AngularDamping.
