Unity C# 错误

Question

I am having some problems with understanding the error messages, have gone through my code to find what is wrong, but can't find any. Please help, I get 25 similar error messages: and they all look like this:

Assets/Scenes/Scripts/GameController.cs(120,113): error CS1061: 'GridSpace' does not contain a definition for 'text' and no accessible extension method 'text' accepting a first argument of type 'GridSpace' could be found (are you missing a using directive or an assembly reference?)

        playerO.panel.color = inactivePlayerColor.panelColor;
        playerO.text.color = inactivePlayerColor.textColor;
    }
}

And the other script looks like this

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class GridSpace : MonoBehaviour
{

    public Button button;
    public string text;
    public Image image;

    private GameController gameController;

    public void SetGameControllerReference(GameController controller)
    {
        gameController = controller;
    }

    public void SetSpace()
    {
        text = gameController.GetPlayerSide();
        image.sprite = gameController.GetPlayerSideImage();
        button.interactable = false;
        gameController.EndTurn();
    }
}

Answer 1

Update: Appears that the code should work ok. I isolated the access to text, and it does work.

void Awake()
{
    //SetGameControllerReferenceOnButtons();
    EndTurn();
    //gameOverPanel.SetActive(false);
    // moveCount = 0;
    //restartButton.SetActive(false);
}

EndTurn() was isolated to just access the gridSpaceList[0...].text:

public void EndTurn()
{
   // moveCount++;

    if (gridSpaceList[0].text == playerSide && gridSpaceList[1].text == playerSide && gridSpaceList[2].text == playerSide)
    {
        //GameOver(playerSide);
    }
    else if (gridSpaceList[3].text == playerSide && gridSpaceList[4].text == playerSide && gridSpaceList[5].text == playerSide)
    {
       // GameOver(playerSide);
    }
    else if (gridSpaceList[6].text == playerSide && gridSpaceList[7].text == playerSide && gridSpaceList[8].text == playerSide)
    {
       // GameOver(playerSide);
    }
    else if (gridSpaceList[0].text == playerSide && gridSpaceList[3].text == playerSide && gridSpaceList[6].text == playerSide)
    {
        //GameOver(playerSide);
    }
    else if (gridSpaceList[1].text == playerSide && gridSpaceList[4].text == playerSide && gridSpaceList[7].text == playerSide)
    {
        //GameOver(playerSide);
    }
    else if (gridSpaceList[2].text == playerSide && gridSpaceList[5].text == playerSide && gridSpaceList[8].text == playerSide)
    {
        //GameOver(playerSide);
    }
    else if (gridSpaceList[0].text == playerSide && gridSpaceList[4].text == playerSide && gridSpaceList[8].text == playerSide)
    {
        //GameOver(playerSide);
    }
    else if (gridSpaceList[2].text == playerSide && gridSpaceList[4].text == playerSide && gridSpaceList[6].text == playerSide)
    {
        //GameOver(playerSide);
    }
    else if (moveCount >= 9)
    {
        //GameOver("draw");
    }
    else
    {
        //ChangeSides();
    }
}

Hierarchy

Inspector gridSpaceList array: Did you set all the references? and add text to them?

I also added text values to each of the game objects for testing. Since the above works ok, try following the the object before it gets to EndTurn(), and see what happens...
