Requires Unity 2018.1.0 or higher.
With Obi Rope you can create ropes in a matter of seconds, with complete control over their shape and behavior. The ropes can collide with the environment and with each other, and can be attached to rigid bodies.使用OBI绳索，你可以在几秒钟内创建绳索，完全控制它们的形状和行为。绳索可以与环境和彼此碰撞，并可以附着在刚性物体上
New in 4.0: ObiRods and the new oriented particle technology allow you to create realistic cables that can be twisted along their length and set to remember their initial shape.与其他绳索解决方案不同，该系统不基于刚性体和接头。这是基于obi粒子，这使得它更轻，更详细，更无条件稳定
This system is NOT based on rigid bodies and joints, unlike other rope solutions. This is based on Obi particles, which makes it more lightweight, detailed, and unconditionally stable.
Available for Windows, Mac, iOS and Android.
Features:
- Procedural smooth mesh generation using splines, complete with tangent space updating and normal map support. No need to manually generate geometry for your ropes.
- Change rope length at runtime. - Tearable/cuttable rope. - Closed loops. - Two-way rigid body interaction.
- Modular solver: don't waste performance, only use the constraints your rope needs.
- Per module adjustable solver iteration count.
- Bending constraints.
- Per particle pin constraints.
- In-editor simulation preview.
- Easy-to-use editor particle tools: selection, brush selection, paintbrush, property smoothing...
- Simulation state gets serialized -> save your ropes mid-simulation->instantiate them already warm-started.
- Supports all standard Unity colliders.
- Automatic camera culling: non-visible ropes do not update their simulation.
