Is there a way to give a sprite a trail?

I would suggest the trail that is spawned is assigned the Fade behavior so that it fades by itself and you'll have less events.

I have managed to make the trail work with some of the suggestions here.

There is an issue though, and that is the trail does not flip with the character, and if you set it to mirror the same as the main character, the whole trail flips every time the character turn.

Any idea how to solve this?

How would you make this into a non fading one, so it goes on forever where you go.
