Fields

lifetime: RandF32

Lifetime of a particle

scale_curve: FireworkCurve<f32>

Evolution of scale over time, applied as a factor to initial scale. The curve should have domain [0,1]

initial_scale: RandF32

Initial scale of particles

acceleration: Vec3

Linear acceleration of particles

angular_acceleration: Vec3

Angular acceleration of particles

linear_drag: f32

Drag applied as a linear coefficient of velocity

angular_drag: f32

Angular drag applied as a linear coefficient of angular velocity

base_color: FireworkGradient<LinearRgba>

Color over lifetime. If a texture is specified the final color will be multiplied.

base_color_texture: Option<Handle<Image>>

emissive_color: FireworkGradient<LinearRgba>

Emissive color over lifetime. If a texture is specified the final color will be multiplied.

normal_map_texture: Option<Handle<Image>>

orm_texture: Option<Handle<Image>>

Occlusion/Roughness/Metallic texture; that is, a texture where the red, green and blue channels represent the material’s occlusion, perceptual roughness and “metallic” setting, respectively. The occlusion value is currently ignored.

fade_edge: f32

Round out the particle with fading at the edges. If 0, no fading is applied. The value should be between 0 and 1.

fade_scene: f32

Fade out at the intersections between particles and the scene to avoid sharp edges. The larger the value, the longer the fade range.

blend_mode: BlendMode

Alpha blend mode for the particles

pbr: bool

Whether to use the PBR pipeline for the particle

collision_settings: Option<ParticleCollisionSettings>

If Some, particles will collide with the scene according to the provided parameters If None, no particle collision will occur.

event_handlers: ParticleEventHandlers
