InvalidCastException: Specified cast is not invalid

Unity Engine

I was just messing around with particle effects and tried to make an explosion effect by instantiating a particle system.

I instantiated the particle effect using this block of code. I don’t fully understand how it works other than that it’s casting the particle effect into rigidbody. I found this from Unity - Scripting API: Object.Instantiate

Rigidbody clone;
        clone = Instantiate(Explosion, transform.position, transform.rotation) as Rigidbody;
        clone.velocity = transform.TransformDirection(Vector3.forward * 10);

When I hit play the particle effect was successfully instantiated but then, I notice that there’s an error message in the console which is bugging me. The error message was
InvalidCastException: Specified cast is not valid.
(wrapper castclass) System.Object.__castclass_with_cache(object,intptr,intptr)

I don’t think Instantiate will return an Object that represents a Rigidbody. It will probably represent a GameObject. Try this:

Rigidbody clone;
GameObject newObj = Instantiate(Explosion, transform.position, transform.rotation) as GameObject;
clone = newObj.GetComponent<Rigidbody>();
clone.velocity = transform.TransformDirection(Vector3.forward * 10);
