FAQPage Schema

How do I migrate my Phaser 3 project to Phaser 4?▼

To migrate your Phaser 3 project to Phaser 4, audit your existing codebase and follow a structured upgrade guide detailing breaking changes and API migrations. Update dependencies, refactor code, and validate behavior across WebGL and Canvas renderers.

What are the breaking changes in the Phaser v4 renderer?▼

The Phaser v4 renderer rewrites core areas by transitioning from pipelines to render nodes. The migration also updates FX and masks to filters, modifies the tint system, and changes camera matrix updates and texture coordinate conventions.

How do I update shader APIs when upgrading to Phaser 4?▼

Updating shader APIs during a Phaser 4 upgrade involves consulting the migration checklist for API evolution details and applying practical examples. The guide provides specific steps to refactor shaders alongside DynamicTexture and RenderTexture updates.

Does migrating Phaser 3 to v4 require updating DynamicTexture and RenderTexture code?▼

Migrating Phaser 3 to v4 requires updating DynamicTexture and RenderTexture code due to changes in texture coordinate conventions and the shader API. The migration guide provides practical steps and examples to refactor these specific texture components.

What is the best way to test a Phaser game after upgrading to v4?▼

The best way to test a Phaser game after upgrading to v4 is to validate behavior across both WebGL and Canvas renderers. The migration guide provides testing strategies and a checklist to ensure end-to-end upgrade requirements are satisfied.
