Constructor Details

TriangleEmitterShape

public TriangleEmitterShape(Vector2D direction,
 float height,
 float width)

Creates a TriangleEmitterShape. The direction is the vector going from the isolated point of the triangle towards the non-equal side. The height is the distance the non-equal side is away from the isolated point, and the width is the width of the non-equal side.

 Ex: direction (0, -1) + height 3 + width 5
 ______
 \    /
  \  /
   \/
 

Parameters:

direction - the direction of the triangle

height - the height of the triangle

width - the width of the triangle

Method Details

nextEmission

public EmissionDetails nextEmission()

Description copied from class: ParticleEmitterShape

Calculates the position and direction details for the next particle emitted.

Overrides:

nextEmission in class ParticleEmitterShape

Returns:

the EmissionDetails for the next particle emitted.

setEmitFromBase

public TriangleEmitterShape setEmitFromBase(boolean emitFromBase)

Sets whether particles should be emitted from the base of the triangle (the isolated point).

Parameters:

emitFromBase - whether particles should be emitted from the base of the triangle

Returns:

this

getCenter

Specified by:

getCenter in class ParticleEmitterShape

Returns:

the center point of the shape

randomPointInShape

protected Vector2D randomPointInShape()

Specified by:

randomPointInShape in class ParticleEmitterShape

Returns:

a random point inside the shape

randomPointOnPerimeter

protected Vector2D randomPointOnPerimeter()

Specified by:

randomPointOnPerimeter in class ParticleEmitterShape

Returns:

a random point on the perimeter of the shape
