I am working on creating a game using the 2D rouge-like tutorial provided by unity. Everything works as expected thus far apart from movement. When the game runs a single error appears.

Unity Object Reference Not Set To An Instance Of An Object Array

'NullReferenceException: object reference not set to an instance of an object completed.player.start () (at Assets/Completed/Scripts/Player.cs:39) '

This is the line of code causing the error:healthText.text = 'Health: ' + health;

The code for the entire script is below:

Check in the inspector if the healthText variable is linked to a UI text object. The link must be not set (None) or otherwise broken (Missing) if you are getting this exception.

I'm working on an adventure game in Unity and ran into this little bug. I'm trying to access a script within an instantiated object. Here is the related line of code:

From my understanding, the first line of code will create a Game Object called prefab2.The second line of code will allow me to access the component (A script) within prefab2.The third line will alter a variable within prefab2's script.

It seems logical to me, however I am getting a 'Object reference not set to an instance of an object' error.

Here are some details, if this helps find a solution.

1. If I just use Instantiate, and leave out the target.GetComponent, the prefab2 will spawn and will not give me any errors... In fact the Initialize script that is attached to prefab2 works just fine.

2. I am calling the CastAbility function from an instantiated child object.

I've tried finding a solution for the last 4 hours, but to no avail.Any help would be appreciated.

I found the solution, the game object was being stored as a transform, rather than a game object. This had me confused because of a similar script I was running that also used a transform (Which worked just fine).
