  How to copy Obi to another computer
Posted by: Sbmhome - 11-09-2018, 08:28 PM - Forum: General - No Replies

I'm moving my project to a new Unity project (same computer). Its the same project I'm working on, but I'm creating a new cleaner code base. I noticed that after I copied my whole project that I'm getting the below error. I know the DLL is there, because I copied the whole project folder. I don't want to reload Obi as I'm deep in my project and don't want the work I have done with Obi to be disturbed.

Error:
DllNotFoundException: c
Obi.ObiMeshTopology.OnDisable () (at Assets/Obi/Scripts/DataStructures/ObiMeshTopology.cs:246)





How do I make sure that Obi (I have Rope and Cloth), get copied over correctly with source control (I use GitHub)?


SOLVED: It looks like the error only appeared on first start up in the new project. Its now working!

  Force Zones and 2D Fluid?
Posted by: newguy1 - 11-09-2018, 05:03 AM - Forum: Obi Fluid - Replies (1)

Hello,

Do the force zones work with 2d fluids? It seems there is no effect on the particles when using either.

  Problems with rope collisions / 'intersections'
Posted by: CageyKG - 11-09-2018, 03:00 AM - Forum: Obi Rope - Replies (2)

Hello,

I'm trying to improve the interaction/collision quality of ObiRope in my vr game. In paricular, I am having numerous issues with the ropes not colliding properly with objects around them. A common example occurs when cables bend around objects and winds up with the object intersecting the cable (presumably because it is between the rope particles?); as seen in image 1 below

I've tried increasing the resolution of the ropes and this seems to help somewhat (see image 2), but not completely. In addition to frequently still having the same problem, it seems to cause issues with distance and bending constraints, making the rope appear all "scrunchy" and making it impossible to get the nice cable "bend" that I can only seem to get with a very low-resolution rope and small bend constraint values (from what I can see, bend constraint values only seem to go so low, and with numerous particles would obviously need to be much smaller to have a visible effect), seen in image 3.

I've tried messing around with the collision solver iterations, including cranking them fairly far up, but nothing seems to make a substantial difference to this issue. Is there any way to improve the quality of these sorts of interactions, or is this particularly tough problem for solvers to handle? Are there recommended settings/configurations to get a more reliable (i.e. fewer instances of them getting stuck in things) simulation in up-close scenarios?

  Cloth to simulate slime
Posted by: arrnav96 - 09-09-2018, 06:06 AM - Forum: Obi Cloth - Replies (35)

Hi, thanks for the reply. Just purchased Obi cloth. 

I'm trying to create a slime simulation game. This is the reference game. Have a few questions regarding the same:

1. Can a soft body cloth surface I make react to user's finger touch as shown in reference? If so, can it create a "hole" in the shape of a finger when pressed on? 

2. Also, does the cloth surface allow mixing of colours on runtime? The reference game I showed also has a feature where a colour can be gradually mixed onto the slime using user's finger.

3. How do I turn gravity off for the cloth? I want it to react to touches and behave like a slimy fluid, without falling down due to gravity. (As if the cloth is actually a slime fluid kept in a bowl) I read the manual but didn't get a clear picture.

  Help integrating with magic leap - Lumin OS
Posted by: ricard2798 - 08-09-2018, 06:09 AM - Forum: Obi Rope - Replies (2)

So i have been trying to make an AR fishing game for a few days, and the prototype is showing promise, but unfortunately, the moment I try to make a build... it does not work.  i basically end up with a stiff rope (almost like a stick), and it looses the pendulum attachment for it.
Anyways, knowing that Magic leap and its Lumin OS is a new system, It is expected that some settings have to be done for it to work correctly.  I experienced something similar to it with playmaker, and basically they told me to do 2 things:

The main thing is there is no PlayMaker dll set to compile with Lumin OS
To fix this, select Plugins\PlayMaker\WebGL\PlayMaker, check Lumin and hit Apply:

and then to do this.

add UNITY_WEBGL to PlayerSettings > Other Settings > Scripting Define Symbols.
Add ";UNITY_WEBGL" to the end of the list (without the quotes).


Any chance you could guide me, if possible, asto what settings i could use to make it work on magic leap Builds?
Thanks in advance

  Rope does not lay flat against collider
Posted by: Dennis59 - 07-09-2018, 09:17 PM - Forum: Obi Rope - Replies (1)

In my project I have a rope attached to a handle GameObject.  Both are laying on a table (GameObject with a box collider) and the desire is that the rope will lay flat against the table.  What is happening is that the handle GameObject sits on the table but the rope arches into the air as shown below.  
[img]<a href=[/img][Image: elevated%20rope_3.png]" />

The table GameObject (gray in the picture above) has a mesh collider and ObiCollider on it.  No colliders on the rope.  I've increased the iterations for the collider object in the solver and tried various values for the thickness parameter on the ObiCollider.  A value of -.018 gets the rope the closest to the table.  Anything more negative than that allows the rope to fall through the table. 

Is there a way to get the rope to lay flat?

  Using Obi Fluid for Mobile Slime Simulation
Posted by: arrnav96 - 07-09-2018, 02:33 PM - Forum: Obi Fluid - Replies (4)

Hi,

I’ve been considering purchasing your asset “Obi Fluid” for making a slime simulation game for android. Before purchasing I just want to be sure, can I use this asset to create something like this? I want to be able to represent a finger pressing on a “goey” fluid on screen so user can interact with the fluid. The fluid should also be able to reform to it’s original shape very slowly, just like real slime.

Is this possible? Will definitely purchase your asset immediately if so. Thanks.

  Unable to Get a Rigid Rope
Posted by: Dennis59 - 07-09-2018, 01:56 AM - Forum: Obi Rope - Replies (2)

I am trying to duplicate the rigid rope in the RopeShowcase (Obj Rope Rigid under the Bending GameObject) in a new project.  I added a rope using ObiRope (Fully Setup) option and then duplicated the settings from the demo scene in my new project.  Unfortunately the rope looks exactly like the "Obi Rope Flaccid" rope in the demo.  I can change settings in the demo for the rigid rope and it responds as you would expect however changing the settings in my scene does nothing.  A screen capture is included below. I must be missing something.  Any suggestions are greatly appreciated. [img]<a href=[/img][Image: Untitled.jpg]" />

  Running 3D Fluid on iOS
Posted by: skicattx - 06-09-2018, 03:17 PM - Forum: Obi Fluid - Replies (5)

Hi,
We want to run a small and reasonably simple water and blood simulation on higher-end iOS devices. So far we have not been able to get the sim running on these devices. I'll post more details of the issues, but before spending more time on this, I have a few questions that I don't see fully answered here. "just use the simple simulation shader" is not an option, as we need the full 3D sim. Advertising seems to imply it should work, so:

1. Should it be possible (performance aside) to run the 3D Obi fluid sim on iOS devices?

2. Is the latest binary compatible with Unity 2017.4.x and 2018.1/2/3.x?
     a. If not, when can we expect compatibility?
     b. Do we need a new iOS binary lib?
