| index | The index to return the chosen Force Field from. |
ParticleSystemForceField The ForceField from the list.
Returns the ParticleSystemForceField at the given index in the influencers list.
When influenceFilter is set to ParticleSystemGameObjectFilter.List then only Force Fields in the influencers list will affect the Particle System.
using UnityEngine;
public class Example : MonoBehaviour { ParticleSystem.ExternalForcesModule externalForcesModule;
void Start() { // Create a default particle system var particleSystemGameObject = new GameObject("Particle System"); var system = particleSystemGameObject.AddComponent<ParticleSystem>();
// Create a force field to influence the particle system var forceFieldGameObject = new GameObject("Force Field"); var forceField = forceFieldGameObject.AddComponent<ParticleSystemForceField>(); forceField.endRange = 5; forceFieldGameObject.transform.position = new Vector3(0, 0, 10);
// Add the force to the particle systems external forces influencers. externalForcesModule = system.externalForces; externalForcesModule.enabled = true; externalForcesModule.influenceFilter = ParticleSystemGameObjectFilter.List; externalForcesModule.AddInfluence(forceField); }
void OnGUI() { GUILayout.Label("Particle System Influencers:"); for (int i = 0; i < externalForcesModule.influenceCount; ++i) { var influence = externalForcesModule.GetInfluence(i); GUILayout.Label(i + ": " + influence.name); } } }
