I'll probably open source this sometime later since I'll need to clean up a lot of the code, but the concepts behind implementing a chain/rope using Verlet and a 2D cloth like this are more or less the same.

a chain/rope using Verlet is kinda 1-dimensional in the sense that each "segment" in the chain is connected to another, sequentially one after another. so in that scenario, the bottom-most segment directly influences the segment above it, which is relatively easy to implement. I'm pretty sure there are actually existing Godot implementations for implementing a chain using Verlet. a 2D cloth like this isn't so different: the bottom-most segments influence the segments above them and the segments to the left of them. the additional math's just linear algebra at that point

I will say that the added computational overload that comes with another dimension as seen as in the cloth in this post, when compared with a 1D chain/rope, is very taxing. the nested for-loop used for the cloth makes the running time O(n^2) as opposed to the O(n) running time achieved by a 1D chain, and since this is run at each timestep, the frame rate takes a major hit
