Can you connect ropes to different moving objects?

It was large so I uploaded it to another external image upload site.

When there is a moving character, the gun is attached as the character's right hand child.

The cup-shaped object is assumed to be attached to the UpperChest bone.
I wanted to connect these two objects with a rope, and I wanted to specify the minimum length of this rope.

Currently, I don't know if the problem is caused by the rope being too thin and small before specifying the minimum length...
The ropes used in the project samples are all large.

When the character moves, the gun or cup object that is the center of the rope will move attached to the character bone.
Will this become a problem in the future?

Hi!

Not entirely sure what I'm looking at in the gif you shared. Looks like the rope has a ObiRopeCursor and it's increasing its length at runtime? You don't need to do that if all you want is to have an object hanging from the gun.

You don't have to do anything in particular to specify a minimum length. All ropes already have a minimum length: the length they have when you create them using the path editor. (aka their rest length).

Thickness and length aren't related in any way. I get the feeling that you're using a cursor to specify the length of the rope at runtime, instead of just making the rope have the length/shape you need at start (using the blueprint path editor as explained in the setup guide).

Cursors are only useful for ropes that must extend/retract at runtime, like cranes of lift/pulley systems.

When the character moves, the gun or cup object that is the center of the rope will move attached to the character bone.

Not at all, that is just an attachment. Why would it become a problem? Attaching ropes to objects of any kind (static, animated or physically simulated) is a very basic and well known use case.

kind regards,
