Help Scripting rod forces

[chenji]

Hi again, I tested various solutions and I wanted to confirm several things.

1. The problem I want to solve is controlling/pushing the cable (rod), but from the middle part, not the tip. 
There are two obstacles on my way, first one is the fact that pushing it requires forces to propagate and it can make the cable very wiggly or stretch even with big amount of substeps (15-20), and second one is keeping the cable fixed by some particle and this is related to second point:

2. Changing particle position teleports it and it does not apply any forces, however if there are other particles, then the whole actor can gain valocity because constraints try to keep particles in their proper positions. In this case does that mean that I should not move rod by changing position of single particle? If yes, then how to move particle via velocity, and keep it pushed, so it does not pull back from forces or collision? Adding velocity or externalForces will stack, while overriding velocity will cancel all other forces plus when I stop movement then velocity is 0, but constraints still apply some and rod moves back. In the end I think I want something like pinhole with maximum friction.

Not sure whether there is any difference but I could add force at the middle of Obi rod with no problem.(Checkout my post, it's a fishing game where I can pull the rod though it's not shown in the gif: https://obi.virtualmethodstudio.com/foru...-4511.html). Could you post a screenshot/video to show the problem and how do you "add force"?
