◆ QQuick3DParticleLineParticle()

QT_BEGIN_NAMESPACE QQuick3DParticleLineParticle::QQuick3DParticleLineParticle ( QQuick3DNode * parent = nullptr)

\qmltype LineParticle3D \inherits SpriteParticle3D \inqmlmodule QtQuick3D.Particles3D

Line particle.

Since
6.4

The LineParticle3D creates line shaped sprite particles.

The line is created from the path of the particle when it moves. The length of the line is specified either by the \l length parameter or the segment count and minimum delta between points. In latter case the length of the line may vary if the particles speed varies.

Member Function Documentation

◆ alphaFade()

float QQuick3DParticleLineParticle::alphaFade ( ) const

\qmlproperty real LineParticle3D::alphaFade

This property holds the alpha fade factor of the line. The alphaFade value range is [0, 1]. When the value is greater than 0.0, causes the line to fade the further the segment is from the first particle segment. The alpha for a segment is calculated like this: segmentAlpha(s) = (1.0 - alphaFade) ^ s, where s is the segment index. The default value is 0.0.

◆ eolFadeOutDuration()

int QQuick3DParticleLineParticle::eolFadeOutDuration ( ) const

\qmlproperty int LineParticle3D::eolFadeOutDuration

This property holds the end-of-life fade-out duration of the line. If set, each line remains in the place it was when the particle reached end of its lifetime, then fades out during this time period. The default value is 0.

◆ length()

float QQuick3DParticleLineParticle::length ( ) const

\qmlproperty real LineParticle3D::length

This property holds the length of the line. If the value is set, the lines length is limited to the value. In this case the minimum delta of the line is the length divided by the segment count. If the value is not set, the line length varies based on the speed the particle moves as well as segment count and minimum delta. The default value is -1.0.

◆ scaleMultiplier()

float QQuick3DParticleLineParticle::scaleMultiplier ( ) const

\qmlproperty real LineParticle3D::scaleMultiplier

This property holds the scale multiplier of the line. The scaleMultiplier value range is [0, 2]. The scaleMultiplier modifies the line size for the line segments. If the value is less than 1.0, the line gets smaller the further a segment is from the first segment and if the value is greater than 1.0 the line gets bigger. The size for a segment is calculated like this: size(s) = scaleMultiplier ^ s, where s is the segment index.

QQuick3DParticleLineParticle::TexcoordMode QQuick3DParticleLineParticle::texcoordMode ( ) const

\qmlproperty enumeration LineParticle3D::TexcoordMode

Defines the texture coordinate mode of line particle.

\value LineParticle3D.Absolute Texture coordinates are specified relative to the world position. \value LineParticle3D.Relative Texture coordinates are specified relative to line first line point. \value LineParticle3D.Fill Texture coordinates are specified such that the texture fills the whole line.

\qmlproperty TexcoordMode LineParticle3D::texcoordMode

This property holds the texture coordinate mode of the line.
