A Particle System for React Native (iOS)

Add particle effects to your React Native app

Add it to your project

iOS

• Run npm install react-native-particle-system --save

Then:

1. Open your project in XCode, select the folder you want project file in, right click it and click Add Files to "Your Folder Name". Look under node_modules/react-native-particle-system and add GPHParticleSystem.xcodeproj.
2. Add GPHParticleSystem to Build Phases -> Target Dependencies.
3. Add libGPHParticleSystem.a to Build Phases -> Link Binary With Libraries.

Then:

• Whenever you want to use it within React code now you can: import ParticleView from 'react-native-particle-system/ParticleView

Usage

A particle system consist of one ParticleView component enclosing one or more ParticleCells. Each ParticleCell in turn encloses an Image component that is used to render the particle:

<ParticleView ...
  <ParticleCell ...
     <Image ... />
  </ParticleCell>
        .
        .
        .
  <ParticleCell ...
     <Image ... />
  </ParticleCell>
</ParticleView>

Both the ParticleView and the ParticleCells are highly configurable each with its own set of properties. Note that some of the ParticleView's properties are multiplied with the ParticleCell's properties to determine the final value. For example, the 'lifetime' property of the ParticleView is multiplied with the 'lifetime' property of a ParticleCell to determine the effective lifetime of that ParticleCell.

All of the properites correspond directly with the properties on CAEmitterLayer/CAEmitterCell, except the lifetime property of the former which is expressed in milliseconds in the JS component.

Future Work

Clearly a version for Android would be welcome.
