Call a function on a script attached to an object

Hi guys,

So, I have a raycaster, and when it hits an object, I want to call a function in the script attached to that object.

Raycast and the (attempt) to call function:

	void Update () 
	{

		Vector2 emitter = transform.position + transform.up*1.5f;

		RaycastHit2D hit = Physics2D.Raycast (emitter, transform.up);

		if (Input.GetKey (KeyCode.Space) & hit != null) 
		{
			hit.collider.gameObject.GetComponent(SpaceThing).Damage(10,0);
		}
	}

The function I am attempting to call, in the script called “SpaceThing”:

public void Damage (float damage, float penetration)	
{
	float mitigation = Mathf.Max(0, (armor-penetration));
	health = health - (damage-mitigation);
}

However, when I try to run, I get error CS0119: Expression denotes a ‘type’ where a ‘variable’, ‘value’, or ‘method group’ was expected

I can’t figure out why it’s doing that :confused: Thanks!

GetComponent in C # is not used correctly, change this:

hit.collider.gameObject.GetComponent(SpaceThing).Damage(10,0);

to this:

hit.collider.gameObject.GetComponent<SpaceThing>().Damage(10,0);
