In the previous version of obirope (3.1) we moved the rope by disabling the entire gameobject, moving the rope to where it needed to be, and then re-enabled it.

Currently in 3.2, this method does not work, with the rope reacting unpredictably (wild/erratic movements) whenever we re enable it.
This movement only takes place for the first few seconds after we enable the rope, before it stabilizes.

Is there a better method to move the rope as of 3.2?

Currently we are also having issues with using the local position of the rope, when we choose to simulate in local space then the pin constraint moves incredibly far away almost instantly, which results in deformation once again.

This solution was for when a simulated rope's parent object was moved relative to other objects (player on a moving platform) and we are currently unable to fix this issue as well.

Many thanks.

Hello, and great product!

Im trying to make a "snake cam" kind of thing in a VR game, where you have the LCD display in one hand, and the camera in the other hand and a rope that connects those together.

My setup loks like this:
https://dl.dropboxusercontent.com/s/u6dz...144053.jpg

with one end pinned to the "CamPart" and the other end pinned to the "JointOrigin". When the SnakeCamera just sits in the scene with kinematic turned of the rope behaves well, but the "CamPart" that hangs on the end jitters like crazy shaking and rotating.

See here:

How can i solve this? Also when grabbing the SnakeCam with one hand (the main part) it kind of goes nuts and the "CamPart" just seems to fly away somewhere.

Hi,

I am trying to achieve cloth physics between two custom meshes in the process of draping the clothes on human. I am trying to achieve the same as in first 5 seconds in this video link "https://www.youtube.com/watch?v=TXAycMilNtg". In this process i am facing difficulty in making my custom cloth behave as the obi cloth. Please help me out in this issue.

Hi all,

My deadline is so close and i am lost with this problem..

I use obi rope as safety rope in climbing VR (Vive) simulation. Other end of the rope is "pin constrainted" to the top of the cliff, other end is "pin constrainted" to the game object named carabine (obi collider) and that game object is child of the body of my player avatar (rigidbody with gravity and obi rigidbody). When I jump down from the cliff, obi rope is affect to my player's rigidbody and vise versa. Everything is working just as I excepted.

BUT!!

I need to attach the other end of the rope (carabine) (make it child of the player's body) AFTER the game start. And this causes issues. Obi rope is no longer affect to my player body rigidbody physics and rope stretch infinity until player is falling to the ground.

This is the problem:

I CAN use code and make game object (carabine) to child of the player's body only in awake function and everything is fine. But when I do this in start function or during gameplay, obi rope is not affect my player's rigidbody.

Yes, I can use fixedjoint on carabine and attach carabine to the players body instead parenting, but that's not what I want and it is not working right either. The joint breaks the connection so easily even if joint's breakforce is set to infinity. There is something that I cannot understand..

This is my game object hierarchy:

In start:
-Player body (rigid body with gravity, obi rigidbody)
-obi rope (pin constrainted to the "carabine" and other end to the "cliff hook")
-carabine
-cliff hook

when player attach the rope to his harness (parenting via code):

-Player body (rigid body with gravity, obi rigidbody)
 --carabine
-obi rope (pin constrainted to the "carabine" and other end to the "cliff hook")
-cliff hook

So why obi rope is not affected to it's parent's rigidbody when parenting the game object (which is pin constrainted to rope) during gameplay using a code but everything is working fine when it is allready child of the parent when the game starts or parenting it using code in awake function? This must be something like obi ropes initialize issue. How can I fix that?

And is this a bug or something?

So sorry of my English and messy explain, but I really need help to this problem as soon as possible.. So please..  

Hello there!
I am planning to make suit on character with simulation that will make nice wrinkes and will react to character underneath.
I wish to check your demo scene with guy with long coat but it's broken.

I am trying to work on UnityChan instead.

I figured out some stuff. That scale of simulation have to be same as object and about numbers of particles in obi solver.

But I am afraid about mesh. UnityChan has sleaves with thickness. As well as my suit. No matter who do I try i cannot make inner part of mesh don't flow over outter mesh. I got confused with what influance moving backwards and what option shows how much mesh can run forward.

I am trying to make mesh less and less stiff (following rig) closer it gets to exit of sleave. But it's all flows like some jelly not like cloth. Paiting weightes is weird here.

Why I am here:
How to make mesh with thickness work good. Or maybe we should remove inside mesh in places where it's not seen.
How can I smooth weighes alongside mesh
I wish to have nice wrinkles in places where cloth curves.
Will that backstop radius enough or I need colliders for stuff like pants.
How to make it not act like jelly.

Thanks a lot!

Currently having issues with quitting based on the rope, where the build just hangs without closing properly, then transitions to not responding.

Documentation does not explicitly mention having to destroy the rope manually, is there something we're missing?
We've previously tried the system process killing method, but aren't sure about it as it has a reasonable chance to not actually close the process itself.

Issue: Cloth lags behind character movement a bit when the Solver is set to World-Space, and FixedUpdate modes both. I get terrible performance from using multiple local-space solvers(not sure why), so I've wanted to shove everything through one world-space solvers.

As I was writing this, I realized that my character script updates movement in Update(), instead of FixedUpdate(). That was the problem. But I figured I'd finish writing this in-case anyone else has this issue.

I didn't see this in the documentation, so this might be something to add on the Solver page.

Hi,

Which parameter to make the cloth stronger so that colliders will not go through the cloth easily? The cloth will only move with the collider unless the collider moves very slowly.

Thank you.

Is there any way to set a rope to not stretch at all and to extend more rope whenever it's pulled? A mode where there is never any strain or tension, and the rope is in a free-fall state, where even gravity will pull on the rope. It's also important to be able to turn this mode off without a sudden spring-back behavior in the rope.

- I've tried using a temporary Obi Handle for the end of the rope, and set the rope's length to the distance between the rope's start & end before disabling the handle; but this didn't help with the spring-back problem.

- I've also tried increasing the rope's length any time the strain (calculated using Rope.CalculateLength() / Rope.RestLength) passes 1. This however was not stable or precise, which made it unfavorable.

This is currently the one thing stopping me from being able to use Obi in my product & it would make my day if I could find a solution for this.

Hi I'm wondering if someone could help me.

I read somewhere that in the new 3.2 version I can disable the ObiRope component to keep some performance when it's not needed. The problem is that when I re-enable the component the simulation/collisions no longer work, although the static mesh is preserved.

I am using Unity v 2017.1.0f3. Any help would be appreciated.
