public bool applyShapeToPosition ;

描述

重写粒子的位置时,将此标志设置为 true 使您可以保留形状模块的影响。

With this flag set to false, the position specified is the exact position where particles spawn from, and the shape module is ignored. If true, the Particle System moves the shape module to the position specified in the EmitParams, then spawns new particles using the shape. See Also: ParticleSystem.EmitParams.position.

using UnityEngine;

// In this example we have a Particle System emitting aligned particles; we then emit and override the position every 2 seconds. public class ExampleClass : MonoBehaviour { private ParticleSystem system;

void Start() { // A simple particle material with no texture. Material particleMaterial = new Material(Shader.Find("Particles/Standard Unlit"));

// Create a Particle System. var go = new GameObject("Particle System"); go.transform.Rotate(-90, 0, 0); // Rotate so the system emits upwards. system = go.AddComponent<ParticleSystem>(); go.GetComponent<ParticleSystemRenderer>().material = particleMaterial;

// Every 2 seconds we will emit. InvokeRepeating("DoEmit", 2.0f, 2.0f); }

void DoEmit() { // Any parameters we assign in emitParams will override the current system's when we call Emit. // Here we will override the position. All other parameters will use the behavior defined in the Inspector. var emitParams = new ParticleSystem.EmitParams(); emitParams.position = new Vector3(-5.0f, 0.0f, 0.0f); emitParams.applyShapeToPosition = true; system.Emit(emitParams, 10); } }
