There's a couple of effects I'm struggling to achieve with the Image API. One is an explosion particle effect, and the other is a contrail effect. I could do this easily with actors, but obviously with images there's not the same blocks.
For the explosion, I'm trying to get them to spread out from a central point, with the contrails I'm trying to make them always draw from the tips of the wings of the planes.
See the image for an explanation.
Your help is gratefully received! Thanks
