# setParticleParams

*Command · Particles · Arma 3 v0.50 · introduced in Armed Assault v1.00*

Locality: arguments **global** · effect **local**

## Description

Set parameters to particle source. Array is in format ParticleArray.

Since Arma 3 version 1.11.114706 you can use this command to overwrite many values set by [setParticleClass](../commands/setParticleClass.md), particularity those defined in ParticleArray. Correspondence between CfgCloudlets class param names and command array of params:

```sqf
particleSource setParticleParams
[
    /*
        String or Array - If string then the name of the particleShape. And following default values are used:
            particleFSNtieth = 1
            particleFSIndex = 0
            particleFSFrameCount = 1
            particleFSLoop = 1
    */
    [
        particleShape,            /* String */
        particleFSNtieth,        /* Number */
        particleFSIndex,        /* Number */
