v3-to-v4-migration

Migrating a Phaser 3 project to Phaser 4 involves mapping deprecated v3 Pipeline and Canvas renderer systems to v4 Render Nodes and Filters, then updating math constants, geometry classes, and shader logic using a structured checklist workflow.

Breaking changes in Phaser 4 involve significant architectural shifts where the v3 Pipeline and Canvas renderer are deprecated, requiring migration to v4 Render Nodes and Filter architectures, alongside updates to geometry classes like Point to Vector2.

Refactoring Phaser 3 geometry for Phaser 4 requires updating geometry classes such as converting Point to Vector2, adjusting math constants, and modifying data structures to ensure compatibility with the v4 rendering pipeline.

Phaser 4 replaces the deprecated v3 Canvas renderer and Pipeline systems with v4 Render Nodes and Filter architectures, necessitating code compatibility analysis and systematic project modernization for existing games.

The best way to track progress during a Phaser 4 migration is utilizing a structured checklist to monitor complex refactoring tasks including shader updates, texture coordinate adjustments, and lighting system overhauls.

Phaser 3 lighting systems fail after upgrading to v4 because of architectural shifts in the rendering pipeline and lighting systems, requiring developers to apply specific refactoring instructions to restore compatibility.
