Question by Glenn1990 · Jan 30, 2015 at 04:42 PM · transformvelocityscaledirection

Change the transform scale based on direction of motion

Hello,

I have a physics object that moves around my screen at various velocities. I want to stretch my object along the direction of motion with an intensity related to its velocity.

I have no problem relating scale to velocity, the problem is I don't know how to change the x,y,z of the scale to relate to the direction its traveling.

In short: How do I scale an object in the direction of its motion.

Um, if I am driving a car, and it stretches the faster I drive, then doesn't it always stretch in the axis which points from the back of the car to the front, that it, the direction I am looking out the front window in. If that's the x-axis, then I'd stretch the car in the x-axis, always.

I see what you mean.

However I should have noted that while the object can travel in any direction. It's rotation will remain fixed.
