Thanks for your answer !

That was actually my first idea and i did this, placing a cube where the motorcycle goes but as the time goes, the scene gets slower and slower :confused:

Did you place a new cube each step or did you stretch the old one and only add a new one when the motorcycle turns a corner?

You could also combine the trails with a batchnode, to reduce the object count.

Why stretch just one side? I’m not sure what you are trying to do there.



What I meant was stretch the whole cube.



Create a long thing cuboid the hight of the trail, width and length both being the width of the trail.

As the bike moves expand the cuboid in the correct direction using the appropriate scale function.
