Object Reference required to access non-static member

Hi there.

I'm trying to implement Unity Ads, and have the script working fine to display the ads. Now I want to set up HandleShowResult and am getting errors.

Here's my code:

#if UNITY_IOS || UNITY_ANDROID
private static void HandleShowResult (ShowResult result)
{
switch (result)
{
case ShowResult.Finished:
Debug.Log("The ad was successfully shown.");

gameController.AddGems(numberOfGems);
gameOverPanel.SetActive (false);
break;

case ShowResult.Skipped:
Debug.Log("The ad was skipped before reaching the end.");
break;

caseShowResult.Failed:
Debug.LogError("The ad failed to be shown.");
break;
}
}
#endif

I have a reference in Start() to access the GameController script that AddGems() is located in.

I'm getting the following errors:

Assets/Scripts/UnityAdsHelper.cs(167,25): error CS0120: An object reference is required to access non-static member `UnityAdsHelper.gameController'

and

Assets/Scripts/UnityAdsHelper.cs(168,25): error CS0120: An object reference is required to access non-static member `UnityAdsHelper.gameOverPanel'

I'm at a loss.

Thanks

 

Where do you create instances of those objects? Can you post that code?

That error means you're trying to use a function associated with a class as if it was static when it's not.

This is static: Mathf.Clamp();

This is not: gameObject.transform;

 

You probably need to understand what the static modifier actually do.

Well, the AddGems() function is in my GameController script:

public void AddGems (int newGemCount)
{
if (gameModeString == "NormalMode") {
if (newGem) {

gemCount += newGemCount;
UpdateGems ();
newGem = false;
} else
newGem = true;
}
}

As for accessing my gameController, at the beginning of my UnityAdsHelper script, I have this:

private GameController gameController;
public int numberOfGems;

And then I set up this:

public void Start(){
GameObjectgameControllerObject = GameObject.FindWithTag ("GameController");
if (gameControllerObject != null)
{
gameController = gameControllerObject.GetComponent <GameController>();
}
if (gameController == null)
{
Debug.Log ("Cannot find 'GameController' script");
}
}
