Raycasting is hitting objects and not hitting them at the same time
My level is a small closed room with colliders where a raycast should not be able to miss. I was getting null reference exceptions so I put the raycast in an if statement, which took away the error but both this line Debug.LogError("Raycast hit nothing"); and this line Debug.Log(hit.transform.gameObject.tag); were being called at the same time constantly.

I'm using unity 2019.3.9. It doesn't seem to be causing any problems but it would be nice to know why this is. Thanks!
Is it possible that you have a copy of this script on some other object unintentionally? This seems like the most likely issue to me.
Double checked, only one object has the script. It does return both while I'm not moving. Now, I'm having a similar, separate problem. The enemy in my game uses a raycast to check if the player is visible (no walls blocking) before the enemy starts shooting. I used this line: Debug.DrawLine(transform.position, hit.point, Color.green, 20f); to check where the raycast is hitting and the ray is going straight through the player. Now, it's not hitting at all until i bump into the enemy a few times.
Do not over complicate the raycast method to excited it you just need this
Void update ()
{
If (// your input method )
{
RaycastHit hit;
If( physics.raycast ( //start position, // direction for example Cam.Forward, out hit, // range or anything that you want optional)
{
// anything you want to do.
}
}
}
Thanks, I will in the future. This doesn't seem to be causing any more issues, thanks.
