ParticleSystemSimulationSpace

Description

Defines the coordinate space in which particles are simulated.

The simulation space determines how particles' positions are calculated relative to their environment. This property controls whether particles are simulated in local space, world space, or relative to a custom transform. The space is defined by the ParticleSystemSimulationSpace enum.

For custom space simulation, use ParticleSystem.MainModule.customSimulationSpace to assign a specific Transform as the reference.

using UnityEngine;

public class ParticleSimulationExample : MonoBehaviour
{
    [SerializeField] private ParticleSystem particleSystem;
    [SerializeField] private Transform customTransform;

    void Start()
    {
        var mainModule = particleSystem.main;

        // Set the simulation space to Custom and assign a transform.
        mainModule.simulationSpace = ParticleSystemSimulationSpace.Custom;
        mainModule.customSimulationSpace = customTransform;
    }
}
