属性
- direction : vector3d
- directionVariation : vector3d
- normalized : bool
详细说明
该元素设置粒子朝目标方向矢量的发射速度。方向向量的长度用作速度大小。
例如,要在 x: 50...150, y:-20..20, z: 0:
ParticleEmitter3D { ... velocity: VectorDirection3D { direction: Qt.vector3d(100, 0, 0) directionVariation: Qt.vector3d(50, 20, 0) } }
属性文档
direction : vector3d |
normalized : bool |
该属性定义应用变化后是否应将方向归一化。设置为假时,变化会影响粒子速度的大小。设置为 true 时,变化会影响方向,但幅度由原始方向长度决定。
默认值为false
