How can I improve physics?

Hello, first of all thank you for taking a few minutes of your time :)

I try to do something similar to a "washing machine" but with balls.

Everything was fine until I noticed how ireal it looked

since my native language is not English, I suppose it will be easier to see it in the capx:

drive.google.com/file/d/18ImyYEi1EWZRHpNC7ml2cYP3OPOorBPi/view

any ideas?

PD: tried many solutions, I saw several capx of examples (including this one: construct.net/en/forum/construct-2/your-construct-creations-23/r0j0s-experiments-69314) but nothing worked for me

Your first link doesn't work. You need to allow access to the file for everyone. (Try opening this link in another browser or in Private Mode, to check if it's working)

Sorry i didn't notice (facepalm)

I think I fixed the link, but just in case, here is another

You can't mix other movement behaviours with physics. It has to be only physics.

blackhornet is right.

Remove Solid and Rotate behaviors. Set Bullet=Yes in Physics properties for balls. Rotate red sprites with physics actions only.

Thank you very much for the tips, I modified everything but I have 2 questions:

I placed a point on the tip of the fin and applied force but it does not rotate

Can I use the "immovable" option or should I use another way to keep the fin fixed?

If necessary, here is the modified capx: mediafire.com/file/awdrliy9glrrm0y/washing_machine_2.capx/file

Rotate with "Set angular velocity" or "Apply torque". Balls should have Circle collision mask. Make sure all origin points are correctly set. Friction and density settings are also important.

Now it looks very real, I spent 15 minutes watching it spin xD

thank you very much, this will be very helpful for the future ^^
