Can't find the null reference

Questions & Answers

I have been coding a combat system for my platformer, and I am now getting NullReferenceException: Object reference not set to an instance of an object

But I just cant find where, Here is the code segment where the error is. health is declared at the start of the function and hit is a raycast2D

if(hit != null){
	health = hit.transform.gameObject.GetComponent<Health>(); //Debugger says error is on this line
	if(health != null){
	    succesful = true;
		health.hit (secondaryPower);
	}else{
		succesful = false;
	}

I am probably just being stupid again, thanks for any help you may give.

Rewrite your first line to:

 if(hit != null && hit.transform != null){

I’ve received conflicting information about RaycastHit2D. It is a struct (so it cannot be a null referene), but I’ve read somewhere that the equals is overridden to make null checks work, but there have been a number of questions come across the list where what I outline (checking hit.collider or hit.transform) is necessary to solve the problem. In fact you could probably not even check if the ‘hit’ is null and just check the transform or the collider.
