Help Change Rope Particle Transform

[sadiq]

i am using different solvers in my case. because picker + dragger did not work with 2 different rope. you sent me Edited( picker and dragger)script. with these scripts ropes behave strange.

Picker and dragger work fine with multiple ropes under a same solver, just tried in several sample scenes. Also the the picker and dragger do not affect the simulation itself, so I don't see how can they change the particle behavior. Can you elaborate on this "strange" behavior you report?

Also i have another question, what is perfect Fixed TimeStep value?

There's no perfect value, it depends on your simulation needs and your performance budget. It should always be set to the highest value that gives you enough quality for your purposes. 0.02 seconds is a good tradeoff for most applications.
