spring lengh / speed of object

[hecta]

is there a script that can change the lengh of a spring depending on the speed of an other object or depending on the speed of rotation of that object ?

You plan to use it as dashboard i suppose. np with that.

Read data in some probe (for example set one of the geom)
density = {v = (readable(owner)).vel; scene.my.speed = (v(0)^2 + v(1) ^2)^0.5; 2}

set spring length = {scene.my.speed/10 + 1}
