How to do dynamic rope/line/chain which can follow nulls?

[Pawel376750718aja]

I need to create a realistic moving rope which can be dynamic rearange by moving one of the null object. Null A should be at the start point of the rope and Null B at the end. It is possible by doing just AE or need some script for it? 

Thanks for any informations!

@Pawel376750718aja there is a free script to do this which is described in two YouTube-videos here:https://youtu.be/uBSouq8feSc?si=2GCm6TWk9TE80HIk and here https://youtu.be/6iP7yZtls68?si=ZtPZuM5qGAYWdHtl&t=128

If you need more control or more accurate physics you might look into a plugin called Newton from Motion Boutique: https://aescripts.com/newton/ or if you just need animated lines check out Connect Layers Pro from the same developer: https://aescripts.com/connect-layers/

Thanks for the answer! I just find other solution. I'm setup a two of my object, rope and null. The important think is to put anchor points of the object in right position because over there will be anchor point for the start and end of the line. Next, by using expression connect line to the object and also null. Null should be in the middle and controll how heavy is the line (also by adding slider, I can controll this by slider or without slider by moving null around). It's pretty simple solution, and works fine. For expressions I recommend use gemini or some other ai software, this is very very simple, but I'm not using this kind of features much right now so it was very helpful!
