Calculating speed along the element's axis

[JAY.ANN]

Is there a way to calculate vehicle's speed along it's X or Y local axis?

I would like to make a recoil system for transport.

Thank you for your attention!

Normally you would get the direction vector X, Y:

And get the length of it: .getLength() / .length

 

This is the 3D variant (useful function):

And this would be the 2D variant:

local speedX, speedY = getElementVelocity(theElement) -- element speed
local speed = Vector2(speedX, speedY).length -- get the direction vector > get .length = direction speed

I cannot implement the above, I don't know why It works incorrect - the speed sets only while the vehicle at moving. I guess I did something wrong.
 

local speedX, speedY = getElementSpeed( veh )
local speed = Vector2( speedX, speedY ).length
setElementSpeed( veh, 1, tonumber( speed - 0.1 ) )

This function returns a number containing the element's speed if the arguments provided are valid. It returns nil plus an error otherwise.

This useful function returns 1 speed value (based on x, y, z)

 

What I explained is how the useful function works and how you can change it more or less from 3D(x,y,z) to 2D(x,y).

Solved, thank you
