SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Helps developers facing challenges while transitioning their Phaser v3 projects to Phaser v4, covering API changes, rendering system updates, and compatibility issues.

Core Features & Use Cases

  • API Difference Guidance: Explains key differences between v3 and v4 APIs and their functionalities.
  • Rendering System Overhaul: Details changes in the rendering system and the need to convert WebGL pipelines to Render Nodes.
  • FX/Mask Conversion: Walks through the migration of effects (FX) and masks from v3 to v4's Filter system.
  • Lighting & Texture Update: Provides solutions for updated lighting and texture coordinate systems.
  • Shader and Geometry API: Describes the updated shader and geometry APIs with examples and best practices.

Quick Start

Run 'migrate' or 'upgrade' commands for Phaser v3 projects to identify compatibility issues and apply recommended updates.

Frequently Asked Questions about v3-to-v4-migration

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I migrate Phaser v3 to v4?▼

To migrate Phaser v3 to v4, convert WebGL pipelines to Render Nodes, reimplement effects and masks using the new Filter system, and update shader and geometry APIs. Run migration commands to identify compatibility issues and apply recommended updates.

What are the key API differences between Phaser 3 and Phaser 4?▼

Key API differences between Phaser 3 and Phaser 4 involve a rendering system overhaul. Developers must transition from WebGL pipelines to Render Nodes, adapt to updated lighting and texture coordinate systems, and utilize the new shader and geometry APIs.

How does the rendering system overhaul in Phaser v4 affect game development?▼

The Phaser v4 rendering system overhaul affects game development by replacing WebGL pipelines with Render Nodes. This architectural change requires developers to restructure rendering logic and adapt existing game code for compatibility.

Do I need to convert WebGL pipelines to Render Nodes for Phaser v4?▼

Yes, you must convert WebGL pipelines to Render Nodes for Phaser v4 compatibility. The migration process details this rendering system overhaul, providing steps to transition custom pipelines efficiently during the version upgrade.

What is the best way to convert effects and masks from Phaser v3 to v4?▼

The best way to convert effects and masks from Phaser v3 to v4 is by reimplementation using the new Filter system. The migration process walks through this FX and mask conversion to maintain visual fidelity.

Can I automatically upgrade my Phaser v3 project to v4?▼

Yes, you can automatically upgrade your Phaser v3 project to v4 by running migrate or upgrade commands. These scripts analyze your codebase to identify compatibility issues and apply recommended API updates for code transition.
