- Namespace: UnityEngine
- Assembly: UnityEngine.ParticleSystemModule
public float radiusScale { get; set; }
Remarks
Useful for improving the visual accuracy of collisions, for example when there is an alpha border in the particle texture. Additional Resources: ParticleSystem.collision.
Examples
using UnityEngine;using System.Collections;[RequireComponent(typeof(ParticleSystem))]public class ExampleClass : MonoBehaviour{ private ParticleSystem ps; public float hSliderValue = 8.0F; void Start() { ps = GetComponent<ParticleSystem>(); var collision = ps.collision; collision.enabled = true; collision.type = ParticleSystemCollisionType.World; collision.mode = ParticleSystemCollisionMode.Collision3D; collision.dampen = 1.0f; var collider = GameObject.CreatePrimitive(PrimitiveType.Sphere); collider.transform.parent = ps.transform; collider.transform.localPosition = new Vector3(0.0f, 0.0f, 13.0f); collider.transform.localScale = new Vector3(20.0f, 20.0f, 20.0f); } void Update() { var collision = ps.collision; collision.radiusScale = hSliderValue; } void OnGUI() { hSliderValue = GUI.HorizontalSlider(new Rect(25, 40, 100, 30), hSliderValue, 0.0F, 2.0F); }}
