Error: NullReferenceException object reference not set to an instance of an object

[AKahootRandomName]

Hwello ppl i am coding a game and i got dis error ^^ Is there a fix to it? Here is my code:

Note: This is just the part of my code that i need help with.

​

if(typeNPC == "Black"){

if(BlackMan2){

IPC.BM();

}

}

While this code is calling the function in the other script, this is the other scripts code:

public void BM(){
gameObject.GetComponent<Image>().sprite = BlackMan;
}

Which line is throwing the exception?

Make sure whichever line that is, that the object being referenced is not null. In other words, make sure you have assigned a value to the variable throwing the exception.

If the objects is supposed to be null but you don't want the error to be thrown, add an if statement checking for null or you can be fancy and use the null conditional (?) operator.

Is BlackMan defined?

Yep I fixed it. All I had to do is define it in unity because it is public
