== Design Workflow == | |||
In order to determine ''one'' particle behaviour, a simple [[drop]] usage in the [[Arma 3: Debug Console|Debug Console]] can do; | |||
but seeing the complete end result can be another task at hand. | |||
=== Using a Script === | |||
One way to design your effect is to have an [[SQF Syntax|SQF]] file, named e.g "particles.sqf", filled with your code: | |||
<sqf> | |||
{ deleteVehicle _x } forEach allMissionObjects "#particlesource"; | |||
private _posATL = player modelToWorld [0,10,0]; | |||
ps1 = "#particlesource" createVehicleLocal _posATL; | |||
ps1 setParticleParams [/* ... */]; | |||
ps1 setDropInterval 0.2; | |||
ps2 = "#particlesource" createVehicleLocal _posATL; | |||
ps2 setParticleParams [/* ... */]; | |||
ps2 setDropInterval 0.2; | |||
</sqf> | |||
and run with | |||
<sqf>execVM "particles.sqf";</sqf> | |||
This format deletes all previous effects and still allows you to use the [[Arma 3: Debug Console|Debug Console]] in order to adjust particle source settings thanks to the usage of global variables (here, {{hl|ps1}} and {{hl|ps2}}). | |||
{{ | === Using a Mod === | ||
'''Emitter 3Ditor''' (a real-time WYSIWYG particle source editor) adds and uses particle and light emitters in your scenarios '''without any scripting nor mod dependency'''.<br> | |||

A particle is a (to some extent, non-physical) 2D plane that always faces the camera, or (more rarely) a 3D model. It can be used to simulate ambient effects, such as dust, fire, water splash, wood splinters and even rock debris.
A particle source is a non-physical object that creates particles at a certain rate and position/velocity.
A particle (as well as a particle source) is local to the computer where the script has been called; one player could see smoke while another could see through without any issue.
How To
Create a Particle Source
Set Source Class
Set Source Parameters
See ParticleArray for details on the array format.
Set Source Drop Interval
Set Source Drop Circle
Set Source Random Values
Set Source Fire Properties
Delete Source
Use the drop Command
The drop command only drops one particle. If multiple ones are needed, a loop (for, while) must be used.
See ParticleArray for details on the array format.
Design Workflow
In order to determine one particle behaviour, a simple drop usage in the Debug Console can do; but seeing the complete end result can be another task at hand.
Using a Script
One way to design your effect is to have an SQF file, named e.g "particles.sqf", filled with your code:
and run with
This format deletes all previous effects and still allows you to use the Debug Console in order to adjust particle source settings thanks to the usage of global variables (here, ps1 and ps2).
Using a Mod
Emitter 3Ditor (a real-time WYSIWYG particle source editor) adds and uses particle and light emitters in your scenarios without any scripting nor mod dependency.
