Make a Massively Multiplayer Ruby Game with Dragon Ruby
summary
Shows how to build real games with Dragon Ruby (SDL under the hood), live-reloads code, and hits 60 fps. Demonstrates a working Flappy Dragon prototype — 355 lines plus a 67-line shader — a player sprite with looping animations, tiled maps via Tiled + TileDriver, collision, and a Stardew-style planting action bound to P. Attempts a multiplayer Gem Collector wired to a Rails API with AnyCable websockets (deploys but live demo fails due to conference Wi‑Fi).
