ParticleArray

Format: [ShapeName, AnimationName, Type, TimerPeriod, LifeTime, Position, MoveVelocity, RotationVelocity, Weight, Volume, Rubbing, Size, Color, AnimationPhase, RandomDirectionPeriod, RandomDirectionIntensity, OnTimer, BeforeDestroy, Object]

Description:

Global parameters:

ShapeName - Name of the shape associated with the particle. AnimationName - Name of the animation of the shape. Type - Type of particle (either "Billboard" or "SpaceObject"). TimerPeriod - The period of calling the "OnTimer" event (in sec). LifeTime - Life time of the particle (in sec).

Physical parameters: Position - Either 3D coordinate (x, y, z) or name of the selection - in this case the Object property must be set. MoveVelocity - 3D vector (x, y, z) which describes the velocity vector of the particle direction and speed in m/s. RotationVelocity - Float number which determines number of rotations in one second. Weight - Weight of the particle (kg). Volume - Volume of the particle (m^3). Rubbing - Float number without dimension which determines the impact of the density of the environment on this particle. 0 - no impact (vacuum).

Render parameters: Note that all these values are set as arrays to show their development in time. If you set the array [1, 2] as a size, then at the beginning the size of the particle will be 1 and at the end of the life time of the particle it's size will be 2. The rest of the values during the life time will be linearly interpolated.

Size - Size of the particle in time to render (m). Color - Colour of the particle in time to render (RGBA). AnimationPhase - Phase of the animation in time.

Random parameters: RandomDirectionPeriod - Period of change of the velocity vector (s). RandomDirectionIntensity - Each MoveVelocity component will be changed with random value from interval <0, RandomDirectionIntensity>. OnTimer - Name of the script to run every period determined by TimerPeriod property. Position of the particle is stored in "this" variable. BeforeDestroy - Name of the script to run right before destroying the particle. Position of the particle is stored in "this" variable. Object - Object to bind this particle to.
