Help How to Pause or Freeze Rope?

[josemendez]

I am using obi rope version 7, I have one solver at the root and multiple ropes in hierarchy downwards. I need to freeze or pause the rope in some cases like its rendered but freezed

Hi,

You can freeze/pause simulation by setting the solver's max steps per frame to zero. Rendering will still be updated and performed.

and not moving even if its parent object is moving too.

That's not possible due to the way transforms work: anytime the parent transform moves, its child transforms move with it.

Is it also possible to do it for only one rope explicitly even if one solver is controlling multiple ropes?

No, since the solver performs a single simulation for all ropes in it: it either updates the simulation or it doesn't.

Also can I extract a mesh in editor and may be replace it with a rope at runtime to depict a freeze?

Yes, right click the rope's extruded renderer and select "Bake Mesh". This will extract and store the current mesh as an asset file in your project, that you can then use as a regular mesh. However re-creating a rope out of a static mesh is not possible.

What's the purpose of this "freezing" in your game? is it due to performance issues?

kind regards,
