Merge Toolkit – Base

The ultimate, most functional, and flexible Merge Toolkit - Base! Build your dream game with seamless scalability and dynamic visuals, all while keeping the core architecture intact.

🛠 Extensions & Customization

──────────────────────

Designed with extensibility at its core, allowing you to build unique mechanics on a stable foundation.

• VContainer Integration — swap any service (moving logic, grid management, etc.) by simply registering your implementation in a custom LifetimeScope.
• Custom Chips — extend the base Chip class to create specialized logic (like the included Generators and Containers).
• Modular Effects — chips bind to effect interfaces, not implementations; replace or add visual feedback via independent prefabs without touching core logic.
• Test-Driven Extensions — included recommended workflow for building and verifying new mechanics using the integrated testing framework.

♟Chips

──────────────────────

Chip Merging & Progression

Combine two compatible chips to create a result chip determined by their types and merge rules (with weighted random outcomes if multiple results are possible). If merge rules specify an extra chip, there's a chance an extra chip spawns on a nearby free cell.

Full details: GitHub - Chip

Chip Generator — Manual & Auto

Flexible generation system supporting both manual (player-triggered) and automatic modes. Charge-based progression with configurable recharge timers and total lifespan. Generators evolve into different chip types after specified recharge cycles. Built-in free-cell detection ensures optimal chip placement; generators intelligently transform when grid space is unavailable.

Full details: GitHub - ChipGenerator

Chip Containers

Collect specific chips to complete containers through flexible requirements based on type or ID. Track completion with the visual effect system. Containers transform into result chips upon fill.

Chip Power Booster

A special chip that boosts parameters of neighboring chips — for example, speeding up nearby generators. Automatically tracks neighbors and visualizes active connections.

♟ Multi-cell Chips

──────────────────────

Chips can occupy any N×M area on the grid.

• Top-left anchor: position always refers to the anchor cell. Secondary cells reference back to the chip. Clicking anywhere on a large chip resolves correctly.
• Chip Relocation: when a merge result needs more space than its parents occupied, neighboring chips move aside automatically. Chips are sorted by size before relocating — larger chips are placed first to reduce fragmentation. If any neighbor has nowhere to go, the whole operation cancels cleanly. No partial field state.

🎨 Effects

──────────────────────

Effect base class with Animator integration (Activate/Deactivate

triggers, safe trigger reset). Ready-to-use effects included:

Blocker effects:

• BoxEffect — blocks chip actions; progressively destroyed by neighboring merges
• ChainsEffect — blocks chip actions; destroyed on the first neighboring merge
• Move Locked — prevents chip from being dragged; triggers shake feedback on attempt

Other effects:

• Merge Available — activates when chip is valid for merge
• Cell Highlight — highlights cells under chip
• Container Requirements — displays item icons required by container
• Generator Charged — activates when generator is fully charged
• Generator Charging — shows generator charging progress
• Power Booster Connector — highlights neighboring chips boosted by booster
• Power Booster Join Links — dynamic links between booster and boost targets
• Shadow — permanent shadow under chip that reacts to movement

🧪 Quality Assurance & Testing

──────────────────────

Comprehensive integration test suite running against real field prefabs (full pipeline, no mocks):

• Stress Testing — Validated via 2000+ random drag operations.
• Logic Validation — Tests for evolution, free space detection, and complex interactions.
• Per-Mechanic Testing — Every core mechanic (Chips, Generators, Containers) comes with its own dedicated test suite.
