UI Sample

This is a demonstration of some simple UI elements, based on the excellent free assets at kenney.nl

• Self-truncating labels
• 9-slice resizable panels
  • A simple glass panel with two options for each corner
  • A complex metal panel where the top edge transitions from blue to metal, with a header label inside
  • A very simple cutout for the above panel
• Progress bars
• Interactive buttons with labels

It's built on some library code:

• Sprite helper class, tying together Assignable, Serializable and attr_sprite
  • Easy to setup new sprites using Sprite.new.tap {|s| s.x = 5 ... }
• ComplexSprite is the basis for many of these, it's a way of combining individual sprites into something that can be displayed and modified as a whole using render_targets.
• TwoStageButton, ThreePanel, NinePanel, NinePanelEdge

The idea is that you could drop the app/lib/ui folder into your project, and create custom elements as in app/ui

Experiment with this code!

Kenney assets are under CC0 license, including modifications made by me to allow for pixel scaling

Suggested things to try:

• Build out the vertical progress bars! This is currently left as a todo.
• Add some more elements from Kenney's assets
• Try creating a nine-slice panel without splitting the assets apart, using source_[x/y/w/h]
