Incrementing and decrementing a text value for a trade

Questions & Answers
1

Im attempting to add and minus from a text value using buttons. What my script currently does is - when I +++++ it shows 5, then I use the - button 3 times and it gives me -3, I then use + and I get 6. I hope this makes it clear.

public class PlusMinusScript : MonoBehaviour {

private int textNumber;
public Text TextObject = null;

public void addOne(){
	if (TextObject != null) {
			textNumber++;
			TextObject.text = textNumber.ToString ();
	}
}
public void minusOne(){
	if (TextObject != null) {

			--textNumber;
			TextObject.text = textNumber.ToString();

	}
}

}

As expected, you have attached the PlusMinusScript script to two scripts. Since the value of textNumber is not shared between these two scripts, your problem occurs.

  1. Attach the PlusMinusScript to only one gameObject (to your TextObject for example)
  2. Drag & Drop the gameObject holding the Text component to the public field of the PlusMinusScript
  3. Select your first button, drag & drop the gameObject in step #1, and select the addOne function
  4. Select your second button, drag & drop the gameObject in step #1, and select the minusOne function
