For my tile puzzle game, how can i have the player cube only step on a tile once and if they step on the tile a second time the game will be lost?

Questions & Answers

I currently have a tile play area where the player can move 1 unit in 4 directions, I have tried a lot to get this to work and so far no luck, I am using a Raycast to detect each tile as the player is on it, and i have the tile change to blue when it is stepped on, but if it is stepped on a second time i would like it to turn to red. I am aware of OnTriggerEnter and Exit but I feel like it would be more convenient to use a Raycast for this to happen.

Thanks in advance for any help.

public boo hasfirstJump = false;

void OnTriggerEnter(collider other){
if(other.compareTag(“playerTag”){
if(hasfirstJump == false){
hasfirstJump = true;
//return
}else
//write your code for level faild
}
}

@Inf1n1teZer0 this might help

using UnityEngine;
using System.Collections;

public class Tile : MonoBehaviour
{
    public Player player;

    public bool steppedOn = false;
    public int steppedCount = 0;

	void Start ()
    {
        player = FindObjectOfType<Player>();
    }

	void Update ()
    {
	    if(steppedCount == 1 && player.gameOver == false)
        {
            transform.GetComponent<Renderer>().material.color = Color.yellow;
        }

        else if(steppedCount == 2 && player.gameOver == false)
        {
            transform.GetComponent<Renderer>().material.color = Color.red;

            StartCoroutine(GameOver());
        }
	}

    private IEnumerator GameOver()
    {
        player.gameOver = true;
        Debug.Log("GAME OVER");

        while(player.gameOver == true)
        {
            foreach(Tile allTiles in player.allTiles)
            {
                allTiles.GetComponent<Renderer>().material.color = Color.red;

                yield return new WaitForSeconds(0.1f);

                allTiles.GetComponent<Renderer>().material.color = Color.yellow;
            }
        }
    }
}

place the top script on all the tile gameobjects and place the player script on your player gameobject

using UnityEngine;
using System.Collections;

public class Player : MonoBehaviour
{
    public bool gameOver = false;

    private Tile hitTile;
    public Tile[] allTiles;

	void Start ()
    {
        allTiles = FindObjectsOfType<Tile>();
	}

	void Update ()
    {
        if(gameOver == false)
        {
            CheckTileRay();
            PlayerMovement();
        }
    }

    void CheckTileRay()
    {
        RaycastHit hit;

        if (Physics.Raycast(transform.position, Vector3.down, out hit, 1f))
        {
            if (hit.collider)
            {
                hitTile = hit.collider.GetComponent<Tile>();

                if (hitTile.steppedOn == false)
                {
                    hitTile.steppedCount += 1;
                    hitTile.steppedOn = true;
                }
            }
        }
    }

    void PlayerMovement()
    {
        if (Input.GetKeyDown(KeyCode.A))
        {
            hitTile.steppedOn = false;
            transform.position += new Vector3(-1, 0, 0);
        }

        if (Input.GetKeyDown(KeyCode.D))
        {
            hitTile.steppedOn = false;
            transform.position += new Vector3(1, 0, 0);
        }

        if (Input.GetKeyDown(KeyCode.W))
        {
            hitTile.steppedOn = false;
            transform.position += new Vector3(0, 0, 1);
        }

        if (Input.GetKeyDown(KeyCode.S))
        {
            hitTile.steppedOn = false;
            transform.position += new Vector3(0, 0, -1);
        }
    }
}
