My RayCast Scripts wont work

using UnityEngine;

public class Bullet_Hit : MonoBehaviour
{
void Update()
{
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit hit;

if (Physics.Raycast(ray, out hit, 100))
Debug.DrawLine(ray.origin, hit.point);

{
RaycastHit Touch;

if (Physics.Raycast(transform.position, -Vector3.up, out hit, 100.0f))
print("Found an object - distance: " + hit.distance);
}

{
RaycastHit Colide;

float Enemy_Health = -10f;

}


}
}

 

More information needed.

 

What am i missing i have gone through multiple tutorials and this is all they say to do

 

Where’s the code? Looks like you messed up your copy paste, you have a class definition with the raycast declaration in it.

 

I have it working now but I'm still putting in my health and damage scripts

 

Now my Health scripts wont work I'm kinda new to this and trying to keep it simple

using UnityEngine;

public class Enemy_Health_Scrpit : MonoBehaviour {

float Enemy_Health = 9f;

if(Enemy_Health <0)
{
Destroy(GameObject);
}
}

 

Do your 'enemies' objects have colliders attached?
