Spicy Particle System

Warning

This extension is not production ready yet. Backup your projects before testing!

Introduction

Spicy Particle System is a powerful and customizable particle system written in C++ as a GDExtension for the Godot Engine. This system is designed to offer improved performance compared to the existing CPUParticles3D while providing extensive customization options for your VFX.

Features

  • Modular Design: Features a modular design with modules divided into generators and updaters. Generators define starting particle parameters, while updaters dynamically update particle properties over their lifetime.

Note

Modules are Resources; only assigned modules are executed. Consider the impact on performance when utilizing multiple modules.

  • 3D transforms: Particles are transformed in three dimensions, providing the flexibility to customize size, rotation, velocity, and more with full control over each dimension.
  • On-Screen Editor: The intuitive on-screen editor allows control of playback and seeking but also displays real-time information on the number of alive particles within the selected system.
  • Random Seed Control: Take command of randomness with precise control over the random seed, allowing for reproducible and fine-tuned variations in your particle system.
  • Emit Rate Over Distance: Dynamically spawn particles based on the distance traveled.
  • Burst Emission: Shedule particles to be emitted at specific time.
  • CPU Alignment: While shader alignment is favored for its efficiency, the system also includes the option of CPU particle alignment.
  • Hierarchical playback: Hierarchical playback synchronizes children systems' playback with the parent system if the direct parent is also a particle system. This feature allows for intricate control over particle system behavior in complex hierarchies.

Big thanks to Bartlomiej Filipek for his blog post - it was extremely helpful and helped me understand how particle systems are written in the first place. I thought that this approach was a great place to start with so this is what this system is based on.

I've resized, optimized and coloured most of them, the main icon is a combination of 2 other icons. With CC and PD licenses.
