I had a question regarding JavaFX and the ability to check a graphic. so within my program, I have a graphics being set for my buttons when the user clicks it.

What I need to find out is what do I need to have inside "temp.getText().equals("O")" and "temp.getText().equals("X")" to make it to where it's checking the button's image name instead of looking for text.

I want the game to say if "X.jpg"(and vice versa for O) is already inside a button then call this error screen popup

As far as I understand the question, you dont want to set the text to the buttons and you want to check what button it is based on the graphic it has(either X or O).

If this is the question, I would recommend to set/update a property of the button based on the type of the image/graphic it is holding, something like

button.getProperties().put("TYPE","X"); //  For X button

button.getProperties().put("TYPE","O"); //  For O button

And you can check directly for the type, rather than accessing the graphic. like..

if(space1.getProperties().get("TYPE").equals("X") && space2.getProperties().get("TYPE").equals("X") && ...){

...

}

Alternatively you can utilize the setUserData() method of the Node which internally uses the above logic only. If you go with userData your code will be less verbose also.

button.setUserData("X");



if(space1.getUserData().equals("X") && space2.getUserData().equals("X") && ...){

...

}

There is no way to keep the file name information in an ImageView or Image. Of course, you can always extend from either of these 2 classes and store the file name as a field, but you probably don't need that.

You can also keep the references of the two Image instances and check for reference instead.

Image imageX = new Image(getClass().getResource("X.jpg").toString());

Image imageO = new Image(getClass().getResource("O.png").toString());



public void playTile(ActionEvent e)

{

    // Other stuff



    Image currentImage = tempImageView.getImage();

    if (currentImage == imageX || currentImage == imageO) // Checking for reference

    {

        // Your logic

    }

    else

    {

        // Your logic

    }

}

The most interesting thing here is that all you wanted to do is to check whether the "tile" has been filled. The simplest way to do this is actually to do if (tempImageView.getImage() == null).
