29 | 30 | And add the following code: 31 | ```kotlin 32 | Particles.with(context, container) // container is the parent ViewGroup for particles 33 | .colorFromView(button)// color sampling from button 34 | .particleNum(200)// how many particles 35 | .anchor(button)// use button as the anchor of the animation 36 | .shape(Shape.CIRCLE)// circle particle 37 | .radius(2, 6)// random circle radius from 2 to 6 38 | .anim(ParticleAnimation.EXPLOSION)// using explosion animation 39 | .start() 40 | ``` 41 | you can get something like this: 42 | 43 | 44 | 45 | You can have more particle annimations by customizing the particle motion curve. The app module in the project shows how to customize it, check it out. 46 | 47 | 48 | 49 | -------------------------------------------------------------------------------- /app/.gitignore:
