Method for make transformation

Hi all.

I want make right transform for sprite in Defold.

My sprite have smoke from train tube. If train change speed - need change upper part of smoke. (flash video show what I want make http://tarnumius.ru/projects/test/smoke.swf)

I tried change go position and scale. I tried animate upper smoke part, but not have any good result.

Anyone can help me?

Thank you for any answers

There is no builtin support for skewing in Defold at this point.
You would have to create your own material for that.
Personally I would create the smoke as a custom “particle system” where puffs of smoke are being released from the pipe and transported/scaled depending on speed.

Andreas has got it: the particle system is exactly what you need here.
