Swinging chain without physics extension

[Konidias]

So I'm having trouble trying to come up with a solution for a simple chain that hangs vertically and is made up of multiple objects, and when the character moves past the chain, the chain will sort of drag with the character a short distance and then come back to a rest.

I'm not looking for like rope swinging or anything using physics... I checked out the Walrus example and it's way over complicated and far more than I'm needing to do.

I just want like 10 objects attached in a vertical line, and being able to slightly sway those objects back and forth, preferably having their angles adjust and swinging in a slight curve.

Does anyone think they could take a crack at making this or should I just keep screwing around with stuff? :P

I will find one of the examples and get back to you. In the mean time, by all means, just keep "screwing around" with stuff.

I think I might just be able to get away with doing it as an animation, but an actual coded method would be appreciated regardless... good for learning.

Use the up and down arrows to swing back and forth.
This example can be applied however you'd like by simply changing the pos value.

I wanted to use real physics, but it seems like you wanted something like this, a simple math function to simulate physics.

[Konidias]

Yes! That's exactly what I wanted. Thanks a ton.

[Eliyahu]

No problem. If you need help with the swinging back and forth then slowly stopping (due to friction), let me know.

[Konidias]

Haha... looks like I need help with that also.

Here's a rough example.

Is there a way to prevent that twitching when the objects line up straight vertically?

[Eliyahu]

The problem is I use the integer X and Y positions, rather than storing them as decimals in alterable values. So when the position is 0, the sin function is going to return 1 rather than 0.9 or such, so the objects expand 1 pixel per link.

Also notice that if you sit at the bottom of the rope, it bounces back and forth, because I add 1 to pos. If you add a smaller value to pos, it looks smoother, but you have to deal with friction better.

I'll leave these fixes up to you, as you need to apply it to your own system anyway.
