name: godot-2d-movement-collision description: 2D movement and collision workflow for snake gameplay in Godot 4.6. Use this when implementing movement, pickup, and death collisions. license: MIT

Keep simulation stable and deterministic.

Implementation notes:

• Move snakes on fixed ticks in _physics_process.
• Store heading as normalized vectors or grid-step directions.
• Use Area2D overlap checks for food pickup and hazard detection.
• Keep collision layers/masks explicit and documented in code.

Validation steps:

1. Verify pickup detection at high speed.
2. Verify self-collision and enemy-collision thresholds.
3. Ensure respawn immunity windows are explicit if used.
