hey there, yeah i will try haha im not the best at explaining things, so the projectile is moving forward at the same time the animation is cycling through the frames and extending backwards, i am sure its mostly to do with how the image is cut and the speed of the projectile also how fast the animation is, i could show the animation sheet i used for this if it would help, im on my mobile right now tho so would need to be tomorrow, your animation looks sweet man and looks like its very close to where u want it
edit: i just noticed there was another way mentioned from Artheios just above my post, i haven't tried that way but i can see how that would work too, so i am not sure what method is easier or suits you the best, i should add that i done it this way because its actually a consumable grapple hook activated from my inventory, and not a spell like your one, the one advantage of using the projectile as far as i can see is the distance of your lightning bolt could possibly travel a further distance and still carry damage outside of the standard grid, however the way that Artheios has mentioned might be a lot easier for an animation like your one, you could set it up the way Artheios has mentioned and possibly add an invisible projectile i am not sure as ive not tried it, only because your animation is more dynamic and expands in all ways, the animation i used only expands in one directions and adds pieces of rope on to the grapple hook in time with the speed of the projectile to give this effect, excuse the wall of text haha i hope some of this has helped
p.s lmk if u need the animation sheet, i got it here if it helps
