ParticleSystem.shape

説明

Script interface for the ShapeModule of a Particle System.

Configures the initial positions and directions of particles.

Particle System modules do not need to be reassigned back to the system; they are interfaces and not independent objects.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Mesh myMesh;

    void Start() {
        ParticleSystem ps = GetComponent<ParticleSystem>();
        var sh = ps.shape;
        sh.enabled = true;
        sh.shapeType = ParticleSystemShapeType.Mesh;
        sh.mesh = myMesh;
    }
}
