Build Game Monster System

Build monsters as gameplay-compatible runtime assets, not decorative meshes.

Establish the contract

Read references/monster-contract.md before implementation or audit. Check the real game content model, combat events, enemy state machine, collision API, camera distance, and asset loader before extending the contract.

Use related skills when applicable:

• Use img2threejs for image-driven procedural reconstruction and its staged visual gates.
• Use build-hybrid-game-assets to choose procedural versus imported representation and record provenance/budgets.
• Use tune-enemy-ai for perception, intent, movement, and behavior transitions.
• Use design-action-combat for startup/active/recovery timing and authoritative contact.
