Good way to make object crawl around backdrops?

[Krim]

Anyone know of a good way to do that? I want it to crawl around backdrops. Basically cling to it like a spider. Also is it something that can be done with an extension? If not is it a hard thing to code? I need the object itself figure out when to turn and what orientation to take so I can't use a bunch of actives to turn it around.

I nearly had something working but now I'm stumped.

Depends on how you define "hard to code"
It can be done by using the algorithm I explain here:

the algorithm gives you both the next position to move to along the surface, as well as the normal angle. Meaning you can just keep moving it to that point and then setting the angle of the object to that value (well technically you want to calculate it on the previous frame, or the angle will always be 1 step behind)

Wow I appreciate the help but that is way above my skill set Any easier way? Maybe with extensions?

use the 'path movement' to just trace around the edges of the backdrop.
