so Sethmaster - all your street posse characters are made using Spriter then? Apart from the workaround for instantiate time, have you noticed any performance overhead issues like Colludium? I'm thinking that maybe, since your animations are instant instead of tweened, that might cut down on some resources. Is that the case?
(sorry to high-jack this post..)
Yes. all of it is made from Spriter.
Regarding overhead, I do know that the last time I created over 10,000 Spriter objects at one time (because I tried use Spriter haphazardly for everything including tiles), there is a lag. The reason so many is created at once is because most of the tile Spriter instances have around 50 objects in them due to my mistake in creating a unique for each different tile in Spriter despite the fact that tiles usually don't have animations and this amount can be reduced to merely one via charactermaps.
By using charactermaps not just for the characters but also for other objects as well, I manage to reduce the amount of objects present at any time significantly. Though for the tiles, I am still not using Spriter for them due to aversion after the last mistake.
Yeah, all the animations are instant and not tweened due to the pixel art. So my experience might differ from others who used tweening. I recommend you try Spriter yourself to see whether the performance ovehead affect your game or not.
