Help Scripting rod forces

[chenji]

Yeah, I tried both methods. The problem is that I don't move rod by pressing the keyboard arrow, but I try to keep it in sync with some depth value - for instance it's 10 meters at some point, but several frames later it will be 11 and rod should reflect that by moving 1m forward.

What are you trying to simulate with Obi rod? Maybe tell us a real world counterpart would be helpful.
