Just wanted to share with you the LibGDX snippet collection I am working on. The idea is to enable almost copy-paste source of some commonly used components in games. The progress is slow, as it is the last item in my priority list, but maybe someone will find this useful. The links above are blog posts, but all of them has the link to fully working sources in my public GitHub repo. Since I am kind of a nab in gamedev, feel free to comment (here, as I disabled the comments in blog so I do not have to deal with moderation tasks) if you see some things which I am doing wrong or just leave a suggestion. I will try to keep this updated.
LibGDX progress bar (+health bar) example
LibGDX window with close button in right top corner
LibGDX floating text example
LibGDX circular progress bar or cooldown timer
LibGDX spell bar
NOTE: the working code for each of the examples can be found in my GitHub repo https://github.com/serhiy (each blog entry though has a link at the end of the post)
