ParticleArray
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,"","",""];
For several examples for the kind of effects that can be accomplished via particles, see ParticleTemplates.
Parameters
Global parameters
ShapeName - Name of the shape associated with the particle (see ParticleShape list).
AnimationName - Name of the animation of the shape.
- In ArmA, the Animation name can be defined as an array (Name, followed by three numbers):
- 1. (Animation texture?)
- 2. Animation type (see image)
- 3. yet unknown
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.
