Game Development How to Make a Video Game Pickups Spawn Pickups Randomly

The variable flyPrefab of FlySpawner has not been assigned

I think there error for me has come through from the last tutorial, because I can't change the name of 'GameObject' to 'Game Manager' in the scene object window, it just goes back to 'GameObject' every time I enter the text.

My next mistake was that I didn't press 'apply' before I deleted the fly.

Then when running the game pressing play so flys spawn and I get this error...

UnassignedReferenceException: The variable flyPrefab of FlySpawner has not been assigned. You probably need to assign the flyPrefab variable of the FlySpawner script in the inspector. UnityEngine.Object.Internal_InstantiateSingle (UnityEngine.Object data, Vector3 pos, Quaternion rot) (at /Users/builduser/buildslave/unity/build/artifacts/generated/common/runtime/UnityEngineObjectBindings.gen.cs:54) UnityEngine.Object.Instantiate (UnityEngine.Object original, Vector3 position, Quaternion rotation) (at /Users/builduser/buildslave/unity/build/Runtime/Export/UnityEngineObject.cs:144) FlySpawner.Update () (at Assets/Scripts/FlySpawner.cs:37)

Please help, I know what I did wrong (I think) but I can't repair it

Can you provide your code?

IMPORTANT NOTE:

If you don't format code, your code will look like this (using the Python language in this example):

def hello(name): print("Hello, {}".format(name)) print("Wuzzup?")

However, if you put the code in this (if you want to post C# code you should replace the Python word after the backticks with c#):

```python

def hello(name): print("Hello, {}".format(name)) print("Wuzzup?")

```

Note: By default Treehouse gets rid of all newlines so the code above is jammed together. But just read on to know how to fix that...

And it'll look like this:

def hello(name):
    print("Hello, {}".format(name))
    print("Wuzzup?")

Please provide formatting also :)
