As mentioned in our Hex Sweeper release, building that game got us thinking about a reusable 4X framework for future projects. That framework is now available on GitHub as PL4X - Phaser Light 4X.
PL4X is built on Phaser 3 and TypeScript and gives you a working hex strategy foundation out of the box. It covers the core loop consisting of a fixed hex grid, full turn-based play supporting multiple human and bot players, a combat system with per-unit stats, damage types, ranged attacks and AoE, pathfinding with movement highlights, and a UI layer with menus and overlays ready to go.
It is still early and intentionally light. The "4X" in the name reflects the direction rather than the current feature set. Features such as fog of war, buildings, and broader genre conventions are on the roadmap. A heavier full-screen 4X framework is planned as a separate project down the line though it all may get wrapped into one. We'll see how it goes.
If you are building a hex strategy game in Phaser, it should give you a solid head start. Check it out on GitHub and let us know what you think.
