KParticle

class KParticle(var x: Float, var y: Float, val vx: Float, val vy: Float, val colorValue: Long, val size: Float, val maxLife: Float, var life: Float = 0.0f)(source)

State container for an individual physics particle in particle-based UI effects.

Constructors

constructor(x: Float, y: Float, vx: Float, vy: Float, colorValue: Long, size: Float, maxLife: Float, life: Float = 0.0f)

Properties

val colorValue: Long

val currentRadius: Float

Current scaled radius based on remaining lifecycle alpha.

val isDead: Boolean

True when the particle lifetime has exceeded maxLife.

var life: Float

val maxLife: Float

val size: Float

var x: Float

var y: Float

Functions

fun update(deltaTime: Float, gravity: Float = 180.0f)

Advance particle physics state by deltaTime seconds.
