scene pausing because of nullref error

[puddleglum]

my code is spoty at best and i know this but i have never had this happen before. basicly i have a pressure plate that alters the players stats. however the player object can move from object to object so i have to put a function in the script to find the player. for a single update after the presure plate is pushed, the player variable is null. normaly i would ignore it but it is infinitly pausing the scene, when i try to unpause it repauses within an update. im very confused

Unfortunately none of that matters for a null reference.

The answer is always the same… ALWAYS. It is the single most common error ever.

Don’t waste your life spinning around and round on this error. Instead, learn how to fix it fast… it’s EASY!!

• also known as: Unassigned Reference Exception
• also known as: Missing Reference Exception

How to find a nullref in Unity3D scripting – PLBM Games

The basic steps outlined above are:

• Identify what is null
• Identify why it is null
• Fix that.

Expect to see this error a LOT. It’s easily the most common thing to do when working. Learn how to fix it rapidly. It’s easy. See the above link for more tips.

You need to figure out HOW that variable is supposed to get its initial value. There are many ways in Unity. In order of likelihood, it might be ONE of the following:

• drag it in using the inspector
• code inside this script initializes it
• some OTHER external code initializes it
• ? something else?

This is the kind of mindset and thinking process you need to bring to this problem:

Why do my Music ignore the Sliders ?

Let me take you step by step through it. You see the error line, line 35? The only possible thing that could be null in that line is audio_BGMusic So that’s part 1. That’s what’s null. We identified it. Part 2… WHY is it null? Well, first we start with “who is supposed to make it not null?” Looking up further I see line 19 sets it, with this construct: audio_BGMusic = ObjectMusic.GetComponent<AudioSource>(); So lets take that apart. How can that fail? We have to suppose it DID fail, so we…

Step by step, break it down, find the problem.

Here is a clean analogy of the actual underlying problem of a null reference exception:

NullReferenceException: Object reference not set to an instance of an object.

Is your particle system assigned to the field in the Inspector on your script? A Null Reference Exception (NRE) is caused when you’re trying to access a method or property on a null object – in other words, trying to get something from nothing. Pretend I give you a set of instructions: I will hand you a package of Oreos. Open the package Take out a cookie. Eat the cookie. Close the package. I hand you the package, you open it, and the container is empty. Your “code” would fail at line 4, be…

well i know why its null and its not a big deal in the game cause it only lasts one update, but its pausing the game for some reasonw which is really annoying and idk why
im gonna debug more and see if i can find anything

Oh, my bad! I misunderstood the point of your question. Look in your console window for something like this!

Right-most button should NOT be on (the above will cause a pause on errors).
