Member Function Documentation

◆ ColorEnd()

ignition::math::Color sdf::v10::ParticleEmitter::ColorEnd ( ) const

Get the end color for all particles emitted.

The actual color will be interpolated between this color and the one set under ColorStart(). Color::White is the default color for the particles unless a specific function is used.

Returns: The end color.

◆ ColorRangeImage()

std::string sdf::v10::ParticleEmitter::ColorRangeImage ( ) const

Get the path to the color image used as an affector.

This affector modifies the color of particles in flight. The colors are taken from a specified image file. The range of color values begins from the left side of the image and moves to the right over the lifetime of the particle, therefore only the horizontal dimension of the image is used. The ColorRangeImage has higher priority than ColorEnd and ColorStart. If all three are set, ColorRangeImage should be used.

◆ ColorStart()

ignition::math::Color sdf::v10::ParticleEmitter::ColorStart ( ) const

Gets the starting color for all particles emitted.

The actual color will be interpolated between this color and the one set using ColorEnd(). Color::White is the default color for the particles unless a specific function is used.

Returns: The starting color.

◆ Duration()

Get the number of seconds the emitter is active.

A value less than or equal to zero indicates infinite duration.

Returns: The number of seconds the emitter is active.
