You use to difficoult shifting mechanism. Use simple lazers.

Yes, it was my first Idea too but my on hit by Laser Script doesn`t work.
Did i make a mistake`?

(e)=>{
e.other.friction := 200
}

Use it its simple.
Like you want to create 3 gears and N and R
You will need 5 lazers.
Lazer script will look like that
First lazer on lazer hit script

{
scene.my.g1 = 1;
scene.my.g2 = 0;
scene.my.g3 = 0;
scene.my.gR = 0;
scene.my.gt = "D1";
}

(scene.my.gt tells what gear is on)

Second gear look like this one
{
scene.my.g1 = 0;
scene.my.g2 = 1; (scene.my.g1 is collision layer of your gear)
scene.my.g3 = 0;
scene.my.gR = 0;
scene.my.gt = "D2";
}

Third one

{
scene.my.g1 = 0;
scene.my.g2 = 0;
scene.my.g3 = 1;
scene.my.gR = 0;
scene.my.gt = "D3";
}
Reverse

{
scene.my.g1 = 0;
scene.my.g2 = 0;
scene.my.g3 = 0;
scene.my.gR = 1;
scene.my.gt = "DR";
}

Your circle script: collision layer
{
scene.my.g1
}

When you make that when you press 1 in your keyboard and your lazer hits a box ones, lazer makes your gear to be collision layer 1, all others 0.

Make your gear (circle) to be about 80kg/h and 0 of restitution and inf of friction.

You can take a look at my gearboxes they all mostly same.

Tell me if you dont get it something

Very nice engine, runs very well! It is a bit heavy though, maybe there is a way to make it a bit lighter? 9/10

Can anyone tell me how those hinge connections are made, so that 2 circles have the same angular velocity without using a shaft? I`m very curious how it works, I haven`t figured it out yet. Thanks in advance

this one would not fit on a car for sure.. its more like a tank or aircraft engine... but nice one

@Mister Pino , actually I made a Tutorial for this some time ago its`s pretty to easy. Just check this Scene out 70445

Thanks a lot man

Is there a variable for hinge impulse (open the Information tab while an axle is selected)? I need it to make a rev limiter for my engine. There will be two circles mounted on the flywheel, connected to it with axles. On the update script, I want to get the amount of hinge impulse and set it to a scene.my variable so I can use it to control throttle.
