You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Length contraction, To be clear I DONOT WANT A PLUGIN
What is the issue? I cannot under stand how would i scale and position things based on a facter, As it must account for CFrame and such, It will most likely not be rotated and be meshparts
What solutions have you tried so far? I’ve tryed looking through souce code of SBS but it is too complex for me
So you want the Part to be resized from the middle and extend on both ends?
In Studio you can hold Shift or Ctrl, drag one of the tool handles, and the Part will either resize from the center, or on all 3 axes.
If you are trying to do this in game you would just change the Part’s Size on one of the axes. The Part would stay centered and would just get longer.
