I’m trying to Instantiate particles in 2D game, but it didn’t show up.
It show up when I drag and drop it from prefab to workspace.

But when I started game it didn’t show up.

See? Particle is spawned but its effect didn’t show up, I don’t know why.
Here, check out my script.

using System.Collections;

public class FireMechanic : MonoBehaviour {
	
	public Renderer rend_f;
	public bool ready;
	public GameObject FireUp;
//	public Vector3 lit;
	// Use this for initialization
	void Start () {
		rend_f = GetComponent<Renderer> ();
		rend_f.enabled = false;
//		lit = GetComponent<Vector3> ();
	}
	
	// Update is called once per frame
	void Update () {
		if (GameObject.Find ("Wood_Dummy").GetComponent<WoodMechanic_D> ().WoodSet) {
			ready = true;
			rend_f.enabled = true;
	}
}
	void OnMouseDown(){
		if (ready == true) {
			Instantiate (FireUp,transform.position, Quaternion.identity);
			print ("lit");
		}
	}
}
