Direction3D

属性

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

该属性定义粒子目标的方向。

默认值为(0, 100, 0) (Y 轴向上)。

另请参阅 directionVariation


directionVariation : vector3d

此属性定义粒子目标的变化方向。

默认值为(0, 0, 0) (无变化)。

另请参阅 direction


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
