Suggestion / Idea Ladder made by Ropes (Ratlines)

[jaripam]

Hey,

Before I dive deeper into this, I was hoping to get some general advice on how to approach my problem.

I'm trying to create ratlines, the rope ladders found on ships, something like this:

I want to add some life to these ropes, also characters should climb up/down.

Would it be advisable to use Obi Rope for this kind of rope setup?
Ideally, I’d like the ropes to be separate, since they might tear apart during gameplay. If not suitable, maybe you have an idea what I can do.

Thanks a lot!

Hi,

You can use ObiRope to do this, but be warned that it's an extremely complex task and it involves a lot more than just the ropes. I wouldn't attempt to tackle it unless you're intimately familiar with physics simulation, IK, procedural animation, character controllers, and the way they interact with each other and game logic. Certainly not a casual feature to add to your game.

Performance considerations are also important, since the amount of ropes and the complexity of their interactions is rather high.

Depending on how you plan your character controller to work and what kind of animation system you'd like to set up, the way you'd implement this varies considerably. I'd be able to help given more details about your use case.

kind regards,

Hey, thanks!

What I intend to do is to have these ladders (and other ropes) to not be static but rather to move realistically with the wind and when characters climb.

I have some years of Unity experience and also I could build the character controller from scratch around this feature.
However, I don't want to go down a rabbit hole where I have to hack in lots of edge-cases and make the whole thing unstable (if I can avoid it). 

So how exactly I approach this, is fully open atm.
 
Maybe an idea, if I make the full ladder as a single mesh instead of multiple single ropes?
Would this work with the other features like tearing and interaction?

I'd prefer a more realistic solution with multiple ropes but if you think the workload would be exponentially higher, I'd rather skip that.
Or if you have any other rough ideas, please let me know
