new Particle(parameters)

Description:
  • 粒子系统，支持火焰、烟雾、团雾等粒子效果，团雾可设置厚度
Source:
  • objects/other/Particle.js, line7
Parameters:
Name Type Description
parameters Object 配置信息
Properties
Name Type Description
kind string 粒子效果类型，默认值ParticleKind.FIRE_SMALL，粒子包括P_Fire_Small、P_Fire_Big、P_Flamethrower P_Smoke_A、P_Smoke_B、P_Smoke_C、P_Smoke_D、P_Sparks_E、P_Mass_Fog、NS_Firefly、NS_Spark
thickness string 团雾厚度，0-1，非必须，默认0.2
spawnRate number 数值越大，Niagara粒子密度越高，非必传, 默认30
brightness number Niagara粒子自发光亮度，非必传, 默认值3
brightnessColor object Niagara粒子自发光颜色，非必传,可以接受{r:,g:,b:}或者THREE.Color, 默认值{r:1,g:0,b:1}
speed number 粒子运动速度，数值越大，Niagara粒子N_Spark的飞行速度越大，非必传，默认5
height number 数值越大，Niagara粒子N_Spark的长度越大，非必传，默认200
width number 数值越大，Niagara粒子N_Spark的宽度越大，非必传，默认0.01
zVelocity number 数值越大，Niagara粒子N_Spark的飞行高度越高，负值则为下落高度，非必传， 默认100
lifeTime number Niagara粒子的生命周期时间，非必传， 默认1，单位秒
renderNum number 每帧渲染的shape数量，默认10，代表每一帧会渲染10个点位，如果点位太多，会导致渲染性能问题,如果超过20个，则自动启用分帧渲染

animate(options) → {TWEEN.Tween}

Description:
  • 动画函数，to中的animateOffset表示位置偏移单位cm
Source:
  • objects/Shape/Shape.js, line828
Inherited From:
Parameters:
Name Type Description
options object {from, to, duration, easing, loop}
Properties
Name Type Description
from object 起始值{position:null,rotation:null,scale:null} 可不设置，不设置就是当前状态
to object 结束值{position:{x,y,z},rotation:{roll,pitch,yaw},scale:{x,y,z},animateOffset:{x,y,z}}
