I've made a game where you can shoot some cans, but I want to add an effect when a can is shot. You know, a kind of explosion or something like that. The way the game works now is: when the can is shot it disappears destroy(gameobject), but I want to add an effect before it disappears. Any suggestions? I want to keep it simple. The effect has to be in within the same method where I destroy the cans.
public void Shot()
{
//Effect should be here
Destroy(gameObject);
}
For a 3D game, a simple particle effect spawned at the location of the can would be easy enough to do. For a 2D game, you could use a particle effect or a sprite animation at the point of impact. Heck, add a sound effect. Doing any of those could happen inside your Shot() function, ideally by calling a Subroutine. Just don't make the effect a child of the can, or it won't finish before the object is destroyed.
public ParticleSystem variable in the script, drag and drop the prefab into that slot in the inspector, then just Instantiate from that variable anytime hit is called.

I recommend you create a prefab with a particle system(or set of them) that also has a despawn timer script attached to it. The particles can be used for an explosion. The despawn script will wait a certain amount of time or until particle systems finish and will be attached to the top-level of the prefab. If you don't know about Prefabs, I suggest you research them because they are uber useful. You can use the Instantiate(Object theObject) function to spawn that prefab. You can make a public GameObject field in the MonoBehaviour of that Shot() method. This would allow you to simply drag the prefab from the Asset Explorer into the properties window for that object.
I hope this helped, if unclear, ask me to fix it.
Create a particle on top of your script
public GameObject effect;
then in your function
public void Shot()
{
//Effect should be here
Instanciate(effect, transform.position, transform.rotation);
Destroy(gameObject);
}
Then in the editor, create an empty gameobject containing you effect and drag it on your script.
UnassignedReferenceException: The variable effect of Shotclass has not been assigned. You probably need to assign the effect variable of the Hit script in the inspector

You should have a look at this SpaceShooter Tutorial from the Unity Website. Especially the Explosions Section https://unity3d.com/de/learn/tutorials/projects/space-shooter-tutorial/explosions?playlist=17147
You might want to tweak this particle Effect to your liking
Now all you need to do is to spawn this particle Effect before your bullet gets destroyed.
Beware to make sure that you destroy your Particle Effect after it has stopped.
You could do this like so:
using UnityEngine;
using System.Collections;
public class DestroyAfterStopped : MonoBehaviour {
private ParticleSystem myParticleSystem;
// Use this for initialization
void Start () {
myParticleSystem = GetComponent<ParticleSystem>();
}
// Update is called once per frame
void Update () {
if(myParticleSystem.isStopped)
{
if (gameObject != null)
{
Destroy(gameObject);
}
}
}
}
Just assign this Script to your ParticleSystem.
