Bug / Crash Downgrade to 5.1 and Rope Particle attachment not work

[josemendez]

Hello, I have working on a project where a rope attached to 2 different dynamic object. I build project at 5.5 but due to ios problems i downgrade it to 5.1 . Now Exacly same code ı used to attach object sometimes works sometimes not. Any help? 


private IEnumerator startingRope()
    {
        rope.GetComponent<MeshRenderer>().enabled = true;

        blueprint = ScriptableObject.CreateInstance<ObiRopeBlueprint>();
        blueprint.resolution = 0.5f;
        blueprint.path.Clear();
        blueprint.path.AddControlPoint(currentBasePoint.transform.position, -Vector3.one, Vector3.one, Vector3.one, 2f, 0.1f, 1, 1, Color.red, "start");
        blueprint.path.AddControlPoint(topPoint.transform.position, -Vector3.one, Vector3.one, Vector3.one, 2f, 0.1f, 1, 1, Color.white, "end");
      // blueprint.path.FlushEvents();

        yield return blueprint.Generate();
       
        rope.ropeBlueprint = blueprint;
        ObiParticleAttachment[] attacher;
        attacher = rope.GetComponents<ObiParticleAttachment>();
        attacher[0].target = currentBasePoint.gameObject.transform;
        attacher[0].particleGroup = blueprint.groups[0];
        attacher[1].target = topPoint.gameObject.transform;
        attacher[1].particleGroup = blueprint.groups[1];



    }




rope sometimes fall to ground sometimes only start work sometimes both work. Couldnt solve the problem here. Unity 2019.3.7f1

My objects have collider and obi collider



falls toward void

This is a bug in Obi, was fixed in 5.3. What iOS issues were you having witb 5.5? It’s compatible with XCode 11.3.1 (latest version with properly working linker), so 5.5 should compile, link and archive fine.
