A simple exmaple how draw and modify jointed lines.

John Eriksson
I needed an easy way to draw and modify jointed lines in one of my projects. I wrote this small proof of concept just to test the algorithm.

The goal was to make it easy to add, insert and move joints.

Hint: Most code is just basic stuff. The interesting part is when you left click on a line to insert a new joint. I use the logic from the LinePointDistance project.

Example usage
  • Left click on an empty space to append a new joint.
  • Left click on a line to insert a new joint on that line.
  • Hold down left mouse button to drag joints.
  • Right click on a joint to delete it.
  • Press SPACE to toggle visual joints.
