Oh shoot that's a bunch of scripting

I've made one on a buggy I made, it only uses some script on one box. You can script with if clauses on the springs themselves, like this:

First of all make a scene.my.g variable, which will be the one used on the gearbox and we'll also use it on the indicator

Then make a system that adds 1 when A is pressed, and subtracts 1 when Z is pressed. Also make it be between, say, -1 and 5. You can use:

scene.my.g > 5? {scene.my.g = 5}:{};
scene.my.g < -1? {scene.my.g = -1}:{}

The system to add 1 and subtract 1 can be made with a couple of variables and a few lines of code. Just keep in mind that you can use keys.isDown("a") in postStep. (or "z" or "shift" or whatever you want). It'll return true when the key is pressed

So now you go to one of the springs, and under length, you write something like this:

length = {scene.my.g == -1? {0.1}:{scene.my.g == 0? {0.15}:{scene.my.g == 1? {0.18}:{scene.my.g == 2? {0.12}:{scene.my.g == 3? {0.11}:{scene.my.g == 4? {0.19}:{scene.my.g == 5? {0.31}:{}}}}}}}}

You basically write
scene.my.g == -1? {0.1}:{}
then you copy it and paste it on the {}, like

scene.my.g == -1? {0.1}:{scene.my.g == -1? {0.1}:{}}
then you change the values. You calibrate each value and you're done


And for the gearbox you have a number for each gear, you just make the radius of one of the gears be something like 0.05 + scene.my.gear/100 and the other one say 0.3 - scene.my.gear / 100.

Thanks for the advice
