◆ QQuick3DParticleTrailEmitter()

QT_BEGIN_NAMESPACE QQuick3DParticleTrailEmitter::QQuick3DParticleTrailEmitter ( QQuick3DNode * parent = nullptr )

\qmltype TrailEmitter3D \inherits ParticleEmitter3D \inqmlmodule QtQuick3D.Particles3D

Emitter for logical particles from other particles.

Since: 6.2

TrailEmitter3D is a special emitter for emitting particles with starting positions inherited from other logical particles.

\qmlmethod vector3d TrailEmitter3D::burst(int count)

This method emits count amount of particles from this emitter immediately.

Note: TrailEmitter3D doesn't support other bursting methods. Position always comes from the particle defined with the \l follow property.

Reimplemented from QQuick3DParticleEmitter.
