Ladder system

I was wondering what you could do for a ladder system like in zelda. I've seen basic ladder systems and understand how they work(like in halo where you just slide up the ladder). The kind I am talking about is where the character goes up/down each step/handle individually and it's not a smooth motion up the ladder.

Like this(Skip to 4:04):

I have ideas on how this could be done, but none of them seem very efficient.
I would like to hear ideas on how you guys would do this.

Thanks!

Disable standard controls entirely and enable a script / flip a boolean that allows ladder controls. Since ladders have variable sizes and there are all kinds, you could make a really basic script for the ladder. When the user "connects" to it, move in steps. You can define how far up or down a step takes you up a ladder, and in your ladder movement & controls, have a brief pause between each step.

 

That's how I thought about doing it. So, would you use a coroutine for the pause in between?

 

I do all of the timing myself in my projects, but from what I've read people using coroutines for, it should work. Given how small the task is, it would be easy to implement either. I suggest finding which option suits your coding style better and would be more applicable for you in future projects at a larger scale.
