public class Test : MonoBehaviour {
//how far you want the ray to fire
private float distance = 100.0f;
void Update ()
{
//where your ray is coming from
Ray ray = Camera.main.ScreenPointToRay(new Vector3(Screen.width / 2, Screen.height / 2, 0));
//what you are hitting with your ray
RaycastHit hit;
//draws a line in your scene to show you were the ray is.
Debug.DrawRay(ray.origin, distance * ray.direction, Color.red);
//this will only hit something that has a collider on it, and will only hold the first object hit
if (Physics.Raycast(ray,out hit,distance))
{
//we hit this object
Debug.Log(hit.collider.gameObject.name);
if(Input.GetKeyDown(KeyCode.F))
{
Debug.Log("We are hitting something and pressed the F key");
}
}
}
}
One thing i an not the best at scripting so how do i set where it comes from i have a First Person Controller as my camera. Thanks for Answering Though! @Deathdefy
