I am working on a video project about car driving and I have to add a animation about forces on the tire. I have to demonstrate how the forces work when the car's tire turn left or right (this force is demonstrated on x axis). When the car accelerates or breaks (this force comes to y axis). On top of that, I want to add a third animated arrow, which is the result of the x and y axis. I would like the arrow to have a constant size head, only want to change the length of the body. Anyone can help me please?
I found your code very useful! As I was new to expressions, I had to read a few tutorials and use some of your code. It works very well and I use the dynamic link with my after effects composition, so I can change the value of the x and y force on two sliders.
