Particle FX Editor

✦ INTRO PROJECT

Hi everyone! I'm currently working on a small project I've named an advanced particle editor using the Shape Painter object. The goal of this tool is to allow the creation of more advanced particles than those offered by default in GDevelop.  Current features: Advanced particle creation Support for custom shapes via SVG (simple shapes for now) More flexible manipulation of particle behavior My motivation: While testing the current system, I realized that we're limited to two main states:

• birth
• death

However, in more advanced engines, we can manage several intermediate states (evolution, transitions, dynamic effects, etc.). So I started developing this tool to allow developers to go further and better control their effects. With this editor, the idea is to be able to: Add multiple intermediate states Modify particle properties at different points in their lifecycle Experiment with richer and more dynamic effects

✦ OVERVIEWS

Complete particle system for GDevelop with 2D (custom 2D object) and 3D (custom 3D object) support. Design effects in the GDParticleFX Editor and import them via JSON.

  -✦ FEATURES

• Multiple emission modes: infinite, burst, finite (reservoir)
• Spawn zones: point, circle, rectangle, line (2D) — sphere, box, line (3D)
• Directional cone with spread, rotation, and elevation (3D)
• Per-keyframe easing: linear, easeIn, easeOut, easeInOut
• Particle shapes: circle, square, triangle, star, diamond, line, custom SVG
• 3D shapes: sphere, cube, diamond, billboard, custom GLB models, textured images
• Runtime overrides: flow, direction, spread, speed/size/opacity multipliers
• Gravity and align to velocity support
• Visual debug guides for cone and spawn zone
• Reverse mode: particles converge toward the emitter

✦ 2D CUSTOM OBJECTS

Works on any 2D layer. Supports Simple SVG, PixiJS Sprite rendered with PixiJS.

✦ 3D CUSTOM OBJECTS

Works on any 3D layer. Supports GLB models, textured billboards, and 3D primitives rendered with Three.js.

✦ GDEVELOP INTEGRATION

1. Export your effect as JSON from GDParticleFX Editor
2. 2D: Add the 2D emitter object to a 2D layer
3. 3D: Add the 3D emitter object to a 3D layer
4. Set the ParticleJSON property — effect plays automatically!
