⚔️ Battle Game — Tactical Grid Combat Engine

---

Disclaimer: This was written by AI as focused ipsum lorem.

Battle Game is a modular, deterministic, tile-based tactics engine built for experimentation, AI development, and rapid prototyping of combat mechanics. It features mobile-friendly interaction, a clean rendering pipeline, and an extensible unit system with movement, attack ranges, zones, and team logic.

---

🎮 Gameplay Overview

• Two opposing teams battle on a grid-based board

• Units have attributes such as:

  • movement

  • damage

  • defense

  • attack range (now min–max range bands)

  • special properties (transfer, collaboration, etc.)

• Combat is deterministic: no randomness, no dice

• Positioning, range bands, and zone control define the strategy

• The game supports both play mode and edit mode for scenario building

---

🧩 Core Features

• Canvas-based renderer with fully drawn background and borders (no CSS artifacts)

• Right-click context menu for placing units during edit mode

• Dynamic team toggle with color-aware UI

• Min–max attack range system (supports donut-shaped threat zones)

• Coordinate overlays for debugging and development

• Mobile-friendly interaction (tap-to-select, large hit targets)

• Fully exportable board images (everything drawn directly on canvas)

• Scalable layout for different resolutions and viewport sizes

---

🛠️ Technical Notes

• Board rendered on an HTML5 ``

• All visuals (background, borders, grid, units, overlays) drawn directly to the bitmap

• No CSS-based drawing → exported images are complete

• Right-click context menu built with lightweight DOM overlay

• Unit definitions stored in key/value sets (e.g., classic_set())

• Placement uses placeUnit(r, c, team, key)

• Attack logic uses Manhattan distance with min–max range bands

• Canvas resizing synchronized between CSS and internal resolution to avoid scroll issues

• Optional viewport-scaled rendering for multi-resolution support

---

🧪 Edit Mode

Edit mode enables rapid scenario creation:

• Right-click a tile → open unit menu

• Select a unit → instantly place it

• Toggle team with the UI switch

• Escape or right-click off → close menu

• Coordinate overlays help with debugging and layout

• All interactions update the board immediately

This mode is ideal for designing puzzles, AI test cases, or tactical scenarios.

🔮 Future Enhancements

• Fog of war

• Line-of-sight and cover mechanics

• Terrain modifiers

• Unit abilities and status effects

• Undo/redo stack

• Save/load scenarios

• AI opponent with threat evaluation

• Zoom and pan for large boards

• Custom emoji-based unit glyphs

📦 Project Goals

Battle Game is designed to be:

• Deterministic — no hidden randomness

• Modular — each subsystem isolated and replaceable

• Extensible — new units, rules, and mechanics drop in cleanly

• Mobile-friendly — touch-first interaction

• Debuggable — overlays, ranges, and editor tools built-in

• Exportable — board state can be saved as an image or serialized

🧠 Design Philosophy

Battle Game is built around clarity, determinism, and expressive mechanics. The engine avoids hidden state, unpredictable behavior, and tangled logic. Every subsystem — rendering, input, unit logic, editor tools — is designed to be:

• predictable

• auditable

• easy to refactor

• easy to extend

This makes it ideal for long-running simulations, AI experiments, and mobile deployment.
