I was following the fourth tutorial video of roguelike scavengers , and I came across with these errors when finished. In the fifth video it fixes some, but these have continued, I'm using the latest version of unity ( 5.1f1 I do not know what else).

Itsaysthatthe3redvariablesintheimagedonotexistinthatcontext,andtheothererrorpointstoalinethatlooksnormal.

Verygoodvideosthathaveexcitedmeenoughtostartmyproject!

Hereisthewholecode:

using UnityEngine;
using System; //Atributo Serializable - aplica variaveis no inspector e editor
using System.Collections.Generic; //Usar lists
using Random = UnityEngine.Random; //Gerar Numeros Aleatorios

public class BoardManager : MonoBehaviour { //padrao

    [Serializable] //tipo de variavel
    public class Count
    {
        public int minimum;
        public int maximum;

        public Count (int min, int max)
        {
            minimum = min;
            maximum = max;
        }
    }


    public int columns = 8; //Quantidade de colunas do mapa
    public int rows = 8; //Quantidade de Linhas do mapa
    public Count wallCount = new Count (5,9); //quantidade aleatoria de numeros internos
    public Count foodCount = new Count (1,5); //quantidade aleatoria de comida

    public GameObject exit; //objetos do jogo, q vao aparecer no mapa ->

I'm not Nils, but I'll answer your question. This is a community where thousands of users are responding, and Nils is just one of many others. Because of this you should direct your question to everyone, not just him.

But anyway, let's go:

These are arrays:

public GameObject [] floorTiles;
public GameObject [] outerWallTiles;

This is a list:

private List <Vector2> gridPosition = new List<Vector2> (); //lista de posiscoes possiveis no mapa

And this is an array as a parameter:

void LayoutObjectAtRandom(GameObject[] tileArray, int minimum, int maximum)

These are attempts to invoke methods:

GameObject toInstantiate = floorTiles(Random.Range(0,floorTiles.Length));
// ...
toInstantiate = outerWallTiles(Random.Range(0,outerWallTiles.Length));
// ...
Vector2 randomPosition = gridPosition (randomIndex);
// ...
GameObject tileChoice = tileArray(Random.Range(0,tileArray.Length));

However floorTiles , outerWallTiles , gridPosition , and tileArray are not methods, but collections of objects.

I think what you wanted was this:

GameObject toInstantiate = floorTiles[Random.Range(0, floorTiles.Length)];
// ...
toInstantiate = outerWallTiles[Random.Range(0, outerWallTiles.Length)];
// ...
Vector2 randomPosition = gridPosition[randomIndex];
// ...
GameObject tileChoice = tileArray[Random.Range(0, tileArray.Length)];

That is, you used parentheses () instead of [] brackets.

Using parentheses after the name of a variable means trying to invoke a method with the name of the variable.
Using brackets after an expression that results in an object (and the name of a variable is an expression) means trying to access an object position that should be a list or array.
