✅ object types?

hey ive been following this video on how to make tictactoe, for a class assignment, (https://youtu.be/AzPgov_stdI?list=PLWeGoBm1YHVj7cYQSglzBU0gb7ecDNf4g) this guy uses images for his X's and O's. i decided to make gameObjects out of 3Dobjects (bc my teacher is not smart and would accuse me of cheating if i use pictures...)

c#
  public void tictactoeButton(int WhichNum)
    {
        tictactoespaces[WhichNum].GameObject = playerIcons[playerIcons];

       

        //...

        if(playerTurn == 0)
        {
            playerTurn = 1;
        }
        else
        {
            playerTurn = 0;
        }
    }

c#
  public void tictactoeButton(int WhichNum)
    {
        tictactoespaces[WhichNum].GameObject = playerIcons[playerIcons];

       

        //...

        if(playerTurn == 0)
        {
            playerTurn = 1;
        }
        else
        {
            playerTurn = 0;
        }
    }

i have this code here which is supposed to mark the spaces when you click them. but i get this error, when i save: Assets\scripts\NewBehaviourScript.cs(39,35): error CS1061: 'Button' does not contain a definition for 'GameObject' and no accessible extension method 'GameObject' accepting a first argument of type 'Button' could be found (are you missing a using directive or an assembly reference?) any help? this is his code btw:

c#
public void tictactoeButton(int WhichNum)
    {
        tictactoespaces[WhichNum].image.sprite = playerIcons[playerIcons];

       

        //...

        if(playerTurn == 0)
        {
            playerTurn = 1;
        }
        else
        {
            playerTurn = 0;
        }
    }

c#
public void tictactoeButton(int WhichNum)
    {
        tictactoespaces[WhichNum].image.sprite = playerIcons[playerIcons];

       

        //...

        if(playerTurn == 0)
        {
            playerTurn = 1;
        }
        else
        {
            playerTurn = 0;
        }
    }

That error is implying that tictactoespaces is an array of Button objects. Is it an array of Button objects?

MicroX•15mo ago

yes

So, Button objects presumably have a property called image but do not have a property called GameObject It's case sensitive

Looks like gameObject is the property name

MicroX•15mo ago

why right here is it GameObject? https://docs.unity3d.com/ScriptReference/GameObject.GetComponent.html

mtreit•15mo ago

That's the type name. Type names and property names are entirely different things. The property name could be anything

MicroX•15mo ago

so wait are u saying i should do tictactoespaces[WhichNum].gameObject = playerIcons[playerTurn];? or tictactoespaces[WhichNum].image.gameObject = playerIcons[playerTurn];?

You're missing a period in there...

MicroX•15mo ago

i get this now:

Assets\scripts\NewBehaviourScript.cs(39,9): error CS0200: Property or indexer 'Component.gameObject' cannot be assigned to -- it is read only

mtreit•15mo ago

Well, apparently the intent is not for you to write to that property. I don't know Unity so I have no idea if what you are trying to do makes sense. But sounds like you are on the wrong track. You might ask for help in #game-dev , there are people who know Unity there.

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
