static angle :Number

Start angle for particle launch in Radians.

Default Value:

• Math.PI / 2

static angleVariation :Number

Variation in the start angle for particle launch in Radians.

Default Value:

• 0

static duration :Number

Duration that the emitter releases particles in ms (used only if emitter is Stream).
After this period, the emitter stop the launch of particles.

Default Value:

• Infinity

static floating :Boolean

Render particles in screen space.

Default Value:

• false

static followTrajectory :Boolean

Update the rotation of particle in accordance the particle trajectory.
The particle sprite should aim at zero angle (draw from left to right).
Override the particle minRotation and maxRotation.

Default Value:

• false

static framesToSkip :Number

Skip n frames after updating the particle system once.
This can be used to reduce the performance impact of emitters with many particles.

Default Value:

• 0

static frequency :Number

How often a particle is emitted in ms (used only if emitter is Stream).
Necessary that value is greater than zero.

Default Value:

• 100

static gravity :Number

Vertical force (Gravity) for each particle.

Default Value:

• 0

See:

• me.sys.gravity

static height :Number

Height of the particle spawn area.

Default Value:

• 0

static image :CanvasImageSource

Image used for particles.

Default Value:

• 1x1 white pixel

See:

• http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html#canvasimagesource

static maxEndScale :Number

Maximum end scale ratio for particles.

Default Value:

• 0

static maxLife :Number

Maximum time each particle lives once it is emitted in ms.

Default Value:

• 3000

static maxParticles :Number

Maximum number of particles launched each time in this emitter (used only if emitter is Stream).

Default Value:

• 10

static maxRotation :Number

Maximum start rotation for particles sprites in Radians.

Default Value:

• 0

static maxStartScale :Number

Maximum start scale ratio for particles (1 = no scaling).

Default Value:

• 1

static minEndScale :Number

Minimum end scale ratio for particles.

Default Value:

• 0

static minLife :Number

Minimum time each particle lives once it is emitted in ms.

Default Value:

• 1000

static minRotation :Number

Minimum start rotation for particles sprites in Radians.

Default Value:

• 0

static minStartScale :Number

Minimum start scale ratio for particles (1 = no scaling).

Default Value:

• 1

static onlyInViewport :Boolean

Update particles only in the viewport, remove it when out of viewport.

Default Value:

• true

static speed :Number

Start speed of particles.

Default Value:

• 2

static speedVariation :Number

Variation in the start speed of particles.

Default Value:

• 1

static textureAdditive :Boolean

Enable the Texture Additive by canvas composite operation (lighter).
WARNING: Composite Operation may decreases performance!.

Default Value:

• false

static totalParticles :Number

Total number of particles in the emitter.

Default Value:

• 50

static width :Number

Width of the particle spawn area.

Default Value:

• 0

static wind :Number

Horizontal force (like a Wind) for each particle.

Default Value:

• 0
