        if (spawned)
        {
            Destroy(laserbeam);
        }
    }
}

this the code and i need to fix the idea is i am trying to spawn a laserbeam the destroying after an amount of time the istantiating it like a obstacle

CodePudding user response：

Destroy has a second parameter for how long after it should be destroyed.

using

 Destroy(gameObject);

will destroy instantly.

using

 Destroy(gameObject, 1f);

will destroy the game object after 1 second.

Call destroy as soon as you create the laserbeam, and set the second param to how long it should be alive.

Scripting reference.
