Essentially I'm trying to create a textbox for my GUI that only accepts 2 int values with a max of 99 and a min of 1, this will be used to set what hp the character will eat at. So, how can I do this to fit what I need?

Have you considered using a JSpinner?

This component should host the functionality that you're looking for, and is a more conventional choice when dealing with this kind of input.

First, why is your JFormattedTextField called eatAtComboBox? 

Second, casting a string to an integer like how you're doing won't always do what you expect. Use Integer.parseInt() instead.

To do what you want add an actionlistener to your start button and set the variable inside that actionlistener using:

eatFoodThreshold = Integer.parseInt(eatAtComboBox.getText());

I've switched it to a JSpinner, but I'm very unfamiliar with it. Would you be able to help me convert a changelistener to an int?

 

		JSpinner eatAtSpinnerBox = new JSpinner();
		eatAtSpinnerBox.addChangeListener(e -> vars.eatFoodThreshold = (int) eatAtSpinnerBox.getChangeListeners());
		eatAtSpinnerBox.setModel(new SpinnerNumberModel(1, 1, 99, 1));

(It was what I was looking for btw thanks alot^-^)

It used to be a comboBox, and I changed it without changing the variable name; I just didn't get around to it yet is all.

I'm happy to help - why do you need a change listener though? And what do you mean 'convert changelistener to an int'?

Sorry if I'm wording it wrong, but how to I get the value of the spinnerBox into the value of what I need what I'm trying right now:
 

JSpinner eatAtSpinnerBox = new JSpinner();
eatAtSpinnerBox.setModel(new SpinnerNumberModel(1, 1, 99, 1));
eatAtSpinnerBox.addChangeListener(e -> vars.eatFoodThreshold = (int) eatAtSpinnerBox.getValue());

I think this is what I was looking for, I'll try it and get back to you.

spinner.getValue() returns the value; no need for anything complicated like changeListeners etc

Why don't you just add an actionlistener to the start button where u would set the vars and everything?

I've given you literally exactly what you need in my previous post. Why read my first sentence and ignore the rest?

Because I was fixing it to suit better to what I needed. Thank you for your input though, it is appriciated. I'm using a JSpinner as Apa suggested.

I've done this in OSBot before. The easiest way is to let the user type whatever they want. When when a user clicks a "submit" button, then your program parses the text, removes all invalid characters using regex, and processes the result. You can do this or detect invalid characters and give an error message.

Edit:

Input: v9 3
Output: 93

Or

Input: v9 3
Output: Error Message
