This is my first proper scene, the script used to apply the speed limit is:

For Y axis:
(Change "X" to the desired speed)

postStep = (e)=>{
vel(1) < -X ? {
vel = [vel(0), -X]
} : {
vel(1) > X ? {
vel = [vel(0), X]
} : {}
}
}
For X axis:
(Change "X" to the desired speed)

postStep = (e)=>{
vel(0) < -X ? {
vel = [-X, vel(1)]
} : {
vel(0) > X ? {
vel = [X, vel(1)]
} : {}
}
}

To use it correctly, make a copy of the object you are using, then give one the first code, and the other the second code, then glue them on top of each other and you're done! Have fun!
