Revival & Resurrection Mechanics

Overview

This skill provides a robust framework for handling player mortality and return. It moves beyond simple "Game Over" screens to integrated risk/reward systems like those found in *Sekiro*, *Hades*, or *Dark Souls*.

NEVER Do (Expert Revival Rules)

Lifecycle & State

• NEVER respawn the player with existing velocity — Always zero out velocity and angular_velocity in revival_state_reset_guard.gd or the player will fly into a wall upon respawning.
• NEVER trust the nearest checkpoint by distance — Always use a 'Progress Index' (revival_checkpoint_validator.gd). Players in non-linear games may wander back to the start area; don't downgrade their respawn point.
• NEVER skip 'Invincibility Frames' (I-frames) — Respawning inside a hazard or near an enemy without a 2s invincibility buffer leads to "Death Loops" and player frustration.

Persistence & Data

• NEVER save checkpoints solely in RAM — If the game crashes, the player loses progress. Use revival_checkpoint_persistence.gd to write to user:// immediately.
• NEVER hardcode checkpoint coordinates — Use Marker3D or Area3D nodes in the scene. Hardcoded coords break as soon as level geometry changes.
• NEVER delete the player node on death — queue_free()ing the player breaks UI refs and references from enemies. Disable processing, hide the mesh, and 'Revive' the existing instance instead.

UX & Pacing

• NEVER respawn instantly — An instant snap is disorienting. Always use a 1-2s delay with a screen fade or death animation to allow the player to process the failure.
• NEVER reset the entire world on player death — In modern design, opened doors and collected unique items should stay persisted. Use a bitmask in the checkpoint resource to track 'World Progress'.
