problem with boolean variable in my game :(

Unity Engine

Hi

i am making game for kids to collect given letters to complete a word with correct order, they drag and drop the letter in the correct place to give them correct or false sound.This is a screen shot and the code for the GameObject (where the player should place the letter) in the scene with just different names of variables of each different GameObject

using UnityEngine;
using System.Collections;

public class GameTrigger2_1 : MonoBehaviour {
    public AudioClip R;
    public AudioClip W;
   
    public bool isCorrect=false;
    public static GameTrigger2_1 Instancei;
    private GameTrigger2_1()
       
    {
        Instancei = this;
    }
    //
   
    public void OnTriggerEnter2D(Collider2D collisionObject){
        if (string.Equals (collisionObject.tag, "i2")) {
            audio.PlayOneShot (R);
            isCorrect = true;
            Debug.Log (isCorrect);
        } else

                audio.PlayOneShot (W);
       
       
    }
   
}

if the player placed all the correct letters in the correct order, GameManager object will execute its code :

void Update () {
        if (GameTrigger2_1.Instancei.isCorrect && GameTrigger2_2.Instancec.isCorrect
            && GameTrigger2_3.Instancee.isCorrect && GameTrigger2_4.Instancec.isCorrect
            && GameTrigger2_5.Instancer.isCorrect && GameTrigger2_6.Instancee.isCorrect
            && GameTrigger2_7.Instancea.isCorrect && GameTrigger2_8.Instancem.isCorrect)
           
            Application.LoadLevel ("Victory2");
       
    }

everything works fine but the problem in my code when i put the letter in the correct place , isCorrect boolean will be true, and if i removed the leter from that place it will stay true, for example , if i want to collect word icecream , if i placed letter ‘i’ in the correct place and remove it , isCorrect will stay true, i want it to return false if i removed it from the correct order and not stuck to true value.

What should i do ? please URGENT Help

Well, you have to set your bool to “false” after you remove it. In your executed code there is only

isCorrect = true;

but never

isCorrect = false;

Set it to false after your Removal-Code.

i know this is the solution , but i dont know how to write a code if i remove the letter from the GameObject, do you ?

you need an OnTriggerExit2D(…) function by the looks of it to handle the tile exiting the collider.
