@The_Kid, I'm not saying I don't trust you. Just giving you good luck upon doing that.
I mean doing the coding at the pressure plates, levers, minecart part where it needs quite an amount of maths.
Good luck trying to make the alignment perfect. I could help creating a custom map with this GM.
Also, good luck doing the maths part. It'd be hard doing the redstone wires, dispenser, redstone circuit's maths.
If you guys still don't understand him :
He wants a code to not let vehicles get on fire when it is low HP and make the the people fire extinguish their own vehicles.
