Community challenge: Create a sort of rope

For questions about using Classic.

Post » Sat Jan 10, 2009 6:47 pm

Goal: create a dynamic rope (static rope animation using bones won't cut it)

Secondary goals:
-allow both endpoints to be able to move
-adjustable length (control slack)
-adjustable digit count (rope resolution)

the more flexible (in terms of potential applications), the better.

here's my start: http://upload.dfyb.net/uploaded/rope_firstattempt.cap (feel free to build on top of this or start from scratch)

not sure if i'm on the right track. interested to see if someone else can come up with a better way to do it. as you can see, i've not yet made it to where it draws anything between the digits.

There kind of was one before with that coarse gravity asteroids thing :)

But yeah, I think it's a neat idea to offer up a challenge and have everyone take a whack at it.

ive already done it with physics

or is that not allowed?

edit: i saw your thing, i guess physics is allowed.

i find your thing represents an elastic more than a rope.

hinges felt really innacurate/unstable to me. it's why i used springs. looking forward to see someone else's stab at it though.

Heh, I like the idea of community challenges. Davo and I came up with this one. You'll need the latest 0.98.4.
It doesn't look as good as Squeemish's, but it uses instances of the same object, instead of a load of clones (which would get kinda annoying in the event sheet editor).

all 3 examples so far have problems when the endpoint is an exact location.


what i had in mind was something like this, but also with the ability to move the endpoints around (as if they were fixed to a moving object).

i assume it is because we're all building a directional rope. it seems like we'll need to do some semi-complex math for the joints to treat both endpoints equally.
