Introduction

Syntax

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


Example

Create thunderbolt on logic named logic1

_pos = [ position logic1 select 0,position logic1 select 1,10 ];
drop ["blesk1","","Billboard",0.01,0.2,_pos,[0,0,0],0,1,1,0,[20 + random 20],[[1,1,1,1],[1,1,1,0.7]],[1,0],0,0,"","",""];


Parameters

Global parameters

ShapeName - Name of the shape associated with the particle.

AnimationName - 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: 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.
