  How to add instantiated prefab camera space fluid effect?
Posted by: skywaver - 01-09-2017, 06:35 AM - Forum: Obi Fluid - Replies (1)

I instantiated a prefabed particle emitter on scene, and added to camera's particle
renderer list, but this added one did not show. But non- screen space effect version
instantiated emitter showed well.

Can I have some tip on this? Thanks for reading.

  Triangle Skin Map editor broken
Posted by: PeterP - 31-08-2017, 04:54 PM - Forum: Obi Cloth - Replies (1)

Hi

I'm trying to use proxies for my cloth simulation but my proxy editor is broken, materials are missing on both source and target mesh and if I try to paint them anyway they disappear from the scene as soon as I click them. I tried it on fresh, clean projects in Unity 5.6.3p1, 5.6.1, 2017.1.0p4 and 2017.1.0p5 on 2 separate machines. Other parts of this plugin seem to work fine.

Hi everybody!

It's been nearly two months at low frequency with Obi. Not much holidays, though.
We had to work on other important things during this time.

¡We are truly sorry if your answer was delayed too much! Indeciso
But now we have spare time again and everything is on fire now. In fact, check out the new release of Obi 3.2 for all assets!

  Rope Position Inconsistencies over Network
Posted by: PhantomBadger - 30-08-2017, 10:58 AM - Forum: Obi Rope - Replies (1)

Hi all,

Im currently working on a networked app with ObiRope, and we have a slight issue wherein the rope has slightly inconsistent positions when networked, now a slight difference is ok, but the difference at the edge of the rope - where it is connected to an object, are quite drastic, often having the rope stick out (See Image below)

[Image: ropepositioncomparisons.png]

For reference, my rope set up is structured as follows:

[Image: ObiRopeSetupDiagram.png]

A - End-point Object A (Connection A in Hierarchy)
B - End-point Connector Object A (Point A in Hierarchy)
C - Obi Rope
[d]D[/d] - End-point Connector Object B (Point B in Hierarchy)
[e]E[/e] - End-point Object B (Connection B in Hierarchy)

[Image: ObiRopeHierarchy.PNG]

Now, my original concern was this was an issue with my network solution. My current solution is to network the positions of the used particles in the ObiRope, Getting and setting them into Oni on each end. This was due to a client requirement to have 1-1 Rope Positions across client and server.

Used by the Server to assign positions to the network:

Code:
   /// <summary>
   /// Sets the rope's current positions to the network using the Oni C++ Solver
   /// </summary>
   private void SetPositions()
   {
       if (entity.isAttached && ObiRope.particleIndices != null)
       {
           //Get the particle positions through the Oni .dll
           Vector4[] particlePositions = new Vector4[ObiRope.UsedParticles];
           Oni.GetParticlePositions(ObiRope.Solver.OniSolver, particlePositions, ObiRope.UsedParticles, ObiRope.particleIndices[0]);

           //Bind them to the network until we're done or hit the hard limit
           for (int i = 0; i < particlePositions.Length && i < PositionArrayHardLimit; i++)
           {
               state.RopePositions[i] = particlePositions[i];
           }
       }
   }

Used by the client to get positions from the network
Code:
   /// <summary>
   /// Gets the rope's current positions from the network and sets our locals to that
   /// </summary>
   private void GetPositions()
   {
       if (entity.isAttached && ObiRope.particleIndices != null)
       {
           //Create a temporary array to hold all the particles we use
           Vector4[] newPositions = new Vector4[ObiRope.UsedParticles];

           //Retrieve the values from the network until we have them all or hit our hard limit
           for (int i = 0; i < newPositions.Length && i < PositionArrayHardLimit; i++)
           {
               newPositions[i] = state.RopePositions[i];
           }

           //Set the particle positions using the Oni .dll in order to apply to the rope
           Oni.SetParticlePositions(ObiRope.Solver.OniSolver, newPositions, newPositions.Length, ObiRope.particleIndices[0]);
       }
   }

With this in mind what could be causing this difference? Especially such a major difference at each end of the rope? My initial thought is it is the rendering portion of the set up, but I'm not sure.

Thanks!

EDIT:
From some further investigation, using Handles seems to be 100% fine, but then I cant move the other end of the rope by using the first, so I would assume the issue is with the pin constraints?

  compiler error on unity 2017
Posted by: lyn_mot - 30-08-2017, 09:09 AM - Forum: Obi Rope - Replies (1)

I just import your package to my project. It has compiler error.

Assets/Obi/Scripts/InspectorButtonAttribute.cs(36,14): error CS0101: The namespace `global::' already contains a definition for `InspectorButtonPropertyDrawer'

When I tried to solve it by deleting the related scripts, it has a lot of error.
Do you know what am I suppose to do with this?

it seems like the package is having crash with standard assets package "third person controller" and crossplatformimput" 
anyone encounter the same problem?

  Get Renderable Particle Count
Posted by: PhantomBadger - 29-08-2017, 11:33 AM - Forum: Obi Rope - Replies (3)

Is there a way to get the number of Renderable particles used in the Oni Solver's Rendering stuff? The intent is to use this in tandem with the Oni.GetRenderableParticlePositions and Oni.SetRenderableParticlePositions methods.

  A question about colliders.
Posted by: kkansy - 28-08-2017, 09:06 AM - Forum: Obi Rope - Replies (2)

Hello!

I'm trying to move ObiRope on a staircase model. Until now I was using a mesh collider created from stair mesh for the collisions but the rope tends to pass through it. I guess it's caused by over-complicated collision mesh. I wonder what would be better approach for stairs collider: a composition of Unity boxes, transformed so that they are matching the staircase shape or a custom collision mesh, a simplified staircase model without so much detailed steps.

I would be grateful for an advice in this matter.

  Grab the middle of a rope?
Posted by: BlueTel - 24-08-2017, 04:16 PM - Forum: Obi Rope - Replies (13)

I'm working on a Vive VR project that will have a loop at the top with a rope threaded through it and each side dangling down.  The user will be able to grab any point along the rope with the motion controllers and pull.  With standard joint ropes, this tends to cause all sorts of physics problems, especially if the user pulls too far too quickly or twists the joints around.

I saw the videos of Obi Rope, and it looks like you can easily move the ends of the rope around without a problem, but would something like this be possible - allowing the rope to be grabbed at different points along its length with virtual hands and pulled around?  And if so, could you maybe point me in the right direction of how to go about it?

Thanks!
