C# setting instantiated prefab variables from another script.

Questions & Answers

Hello, I’m attempting to make a GameObject prefab instantiate when a certain object is destroyed, however, I need to be able to alter the variables instantly upon creating it, my issue comes when I’m trying to access the variables, I don’t have a clue how to do this on instantiated objects, here is all the needed base code in the function:

void HitByRay()
{
	GameObject go = (GameObject)Instantiate (thingamabob, transform.position, transform.rotation);

	Destroy (gameObject);
}

How am I to go about setting the variables on the particularly spawned prefab instance?.

Presumably you have some script on your instantiated object? Maybe a ‘Thing’ script. So you would do:

void HitByRay()
{
    GameObject go = (GameObject)Instantiate (thingamabob, transform.position, transform.rotation);
 
    //get the thing component on your instantiated object
    Thing mything = go.GetComponent<Thing>();

    //set a member variable (must be PUBLIC)
    mything.somepublicmember = 10; 

    //call a member function (must be PUBLIC)
    mything.somememberfunction();

    //maybe access one of the built in components (such as a rigid body if it has one)
    go.rigidbody.velocity = new Vector3(10,0,0);
 
    //destroy the original object as normal
    Destroy (gameObject);
}

FYI: In that code, I’m assuming that whatever script that contains the HitByRay function has a member called thingamabob, which is a GameObject, and has been set (probably in the editor) to reference an existing prefab, which contains a Thing component.
