I’m using Godot & Blender for ‘Sketch Siege’

But, if you’re talking about ‘Plataform Stick-Fight’ I use Sticknodes for most of it.
I make the assets as if it was with any other 2D software, to then export it in PNGs at 1080p.
Later on, I get on ‘Documents’ which is in the AppStore and really good!
Once I’m there, I make a .zip file with all the assets I’m gonna implement in that transportation (which are numbered) EG; 100 frames.

I number them and get them all sorted out.
Then I upload them to megafire and download it on my pc, with the power of ClickTeam fusion I make an object and assert the animations where they belong. That’s pretty much it. If you’d like me to do a simple tutorial I will be willing to!
