Cant Find The Variable In Another Script?

Questions & Answers
1

Hi :slight_smile:

Rookie question, but I am trying to get the “speed” variable from a script called “CheckSpeed” in the “Player” game object. I have checked every spelling and it insists on saying:
“‘speed’ is not a member of ‘UnityEngine.Component’”

What am I doing wrong?

My Script So Far:

var bullet : Rigidbody;
var bulletSpeed = 100;
var shipSpeed : float;

function Update () {
	
	shipSpeed = transform.Find("Player").GetComponent("CheckSpeed").speed; // ???
	
	if (Input.GetMouseButtonDown(0))
	{
		FireGun();
	}

}


function FireGun()
{
	var clone = Instantiate(bullet, transform.position, transform.rotation);
	
	audio.Play();
	
	clone.velocity = transform.TransformDirection(Vector3(0, 0, bulletSpeed + shipSpeed)); 
	
	Destroy (clone.gameObject, 3);

}

This should be a very simple solution, but it has stumped me for a good hour. I have never got the hang of referencing variables from other scripts/gameobjects. I wish I could just say stuff like “script.parent.parent.Part” :stuck_out_tongue:

Also I’d like to add, I know this question has been asked a lot and there is a good page by Unity explaining a solution. But despite reading and following them, it doesn’t seem to help.

Thanks :slight_smile:

Take out the quotes around CheckSpeed:

shipSpeed = transform.Find("Player").GetComponent(CheckSpeed).speed;

When you call GetComponent() with a string, it does not know the type to return, so it returns a reference to ‘Component.’ But ‘Component’ does not have a ‘speed’ variable. If for some reason you want to use the string form of GetComponent(), then you must cast the return value.
