How to register if my Raycast hits nothing(Solved)
Sorry if I word this incorrectly, but how do I register if a raycast hit returns null ?
At the moment I'm simply using a crude method of having an invisible wall behind the player (lowerWall) and having the raycast register that if it hits nothing else.
if(Physics.Raycast(shootingRay, out hit, attackDistance))
{
if(hit.collider.tag == "LowerWall")
{
Debug.Log("Searching");
}
else
if(hit.collider.tag == "ShieldCube")
{
Debug.Log("Blocked");
canFire = false;
}
else
if(hit.collider.tag == "Enemy")
{
canFire = true;
InvaderFireWeapon();
}
if(hit.collider.tag == "Player")
{
canFire = true;
InvaderFireWeapon();
}
}
Is there a way programmatically to check if a raycast doesn't actually hit anything
I tried -
if(hit.collider == null)
{
Debug.Log("Searching");
}
This didn't throw up any errors, but it didn't actually do anything either.
Any help greatly appreciated.

Yes. If the raycast doesn't hit any collider, it returns false.
So, do it in the else statment. Simple!
if(Physics.Raycast(shootingRay, out hit, attackDistance))
{
// executes if hits a collider
}
else
{
// executes if it doesnt hit any collider
}
Sorry for late reply. Anyway.. works fine now, many thanks

If no collider is hit, hit.collider will be null, so you can also check for it this way:
if (hit.collider == null)
{
}
First answer that actually considers the real problem. I was calling it from another script so I needed to check hit and the popular obvious answer was not a solution for me.
