Rope ends didn't move correctly

[josemendez]

The object is moving with NavmeshAgent movement, and the attachment is static, should I make it dynamic? and what's the difference between static and dynamic?

Static attachments do not provide two-way interaction. This means the rope will follow whatever object it is attached to, but won't apply forces to it.

Dynamic attachments implement two-way interaction. The rope will follow the object, and also apply forces to it. You could use these to hang objects from a rope, for instance.

Using a NavmeshAgent, a static attachment should be enough if you don't want it to be driven by the rope. In this case, just make sure the agent is moving before the solver is updated each frame.
