A constraint is an invisible connection between 2 objects. Like when you connect a wheel to a stick, or the rope bridges in drive mad. You probably only want to do this once, on Play.

Notes

Have you ever heard of hydraulics and motors? If not then let me explain it to you and the connection of it in this script:

Hydraulic and Motors are both type of motors that produces different movements using either similar or different elements:

• Hydraulic – from the word hydro, usually uses fluids (either water or air) to produce Linear Motor movements that can also be achieved with the use of gears and Rotary Motor in real life.
• Motor – the most common motor we know. It produces rotary movements. In Fancade we can produce something like it with the help of constraints and Angular Motor

So, to be exact: Constraints are basically the relations of motors, pivotals , gears and springs!
