overlap2d-runtime-kha-g2

progress

• images - usable, wip
• composites - usable, wip
• spriter animations - usable, wip - using forks of wighawags spriter runtime for kha; https://github.com/sh-dave/spriter + https://github.com/sh-dave/spriterkha/tree/scaling
• spine animations - not planned for now
• sprite animations
• ninepatches
• particles
• lights - not planned for now
• ui (labels / buttons / ...)

notes

• very rudimentary, unoptimized and uncustomizable runtime library for kha/g2
• mainly to render stuff and see if my haxe-format-o2d parsing works
• probably won't ever be a full fledged runtime b/c everyone and their mom has their own engine/framework/ecs-system, and it doesn't make sense to try and reinvent the wheel once again
• if you think it would be useful to you, open an issue for discussion
• you can use it as learning resource on how to iterate the parsed data though
• or maybe something like a builder/factory would make sense so other engines could easily customize a simple wrapper to convert the data to their preferred runtime format?
• but might just be a waste of effort as it's probably done in 20 loc anyway?
