粒子系统 CustomDataModule 的脚本接口。
配置完成后,该模块将生成自定义的每粒子数据,供您在脚本或着色器中使用。
要在脚本中读取这些数据,只需调用 ParticleSystem.GetCustomParticleData。
要在着色器中读取它们,请在 ParticleSystemRenderer 模块中启用自定义数据流,或从脚本调用 ParticleSystemRenderer.EnableVertexStreams。启用后,自定义数据将通过 TEXCOORD 通道传递到顶点着色器。ParticleSystemRenderer Inspector 将告诉您正在使用哪些通道。
不需要将粒子系统模块重新分配回系统;它们是接口而不是独立的对象。
另请参阅:ParticleSystemRenderer.EnableVertexStreams。
using UnityEngine; using System.Collections;
[RequireComponent(typeof(ParticleSystem))] public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var customData = ps.customData; customData.enabled = true;
Gradient grad = new Gradient(); grad.SetKeys(new GradientColorKey[] { new GradientColorKey(Color.blue, 0.0f), new GradientColorKey(Color.red, 1.0f) }, new GradientAlphaKey[] { new GradientAlphaKey(1.0f, 0.0f), new GradientAlphaKey(0.0f, 1.0f) });
customData.SetMode(ParticleSystemCustomData.Custom1, UnityEngine.ParticleSystemCustomDataMode.Color); customData.SetColor(ParticleSystemCustomData.Custom1, grad); } }
