Description
This is my mazenode.cs file
public enum NodeState
{
Available,
Current,
Completed
}
public class mazenode : MonoBehaviour
{
[SerializeField] GameObject[] walls;
[SerializeField] MeshRenderer floor;
public void Removewall(int walltoremove)
{
walls[walltoremove].gameObject.SetActive(false);
}
public void SetState(NodeState state)
{
switch (state)
{
case NodeState.Available:
floor.material.color = Color.white;
break;
case NodeState.Current:
floor.material.color = Color.yellow;
break;
case NodeState.Completed:
floor.material.color = Color.blue;
break;
}
}
}
This is my mazegenerator file
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class mazegenerator : MonoBehaviour
{
[SerializeField] mazenode nodePrefab;
[SerializeField] Vector2Int mazeSize;
private void Start()
{
StartCoroutine(GenerateMaze(mazeSize));

IEnumerator GenerateMaze(Vector2Int size)
{
List<mazenode> nodes = new List<mazenode>();
//This is creating nodes
for (int x = 0; x < size.x; x++)
{
for (int y = 0; y < size.y; y++)
{
Vector3 nodePos = new Vector3(x - (size.x / 2f), 0, y - (size.y / 2f));
mazenode newNode = Instantiate(nodePrefab, nodePos, Quaternion.identity, transform);
nodes.Add(newNode);
yield return null;
}
}
List<mazenode> currentPath = new List<mazenode>();
List<mazenode> completedNodes = new List<mazenode>();
// Choose starting node at random
currentPath.Add(nodes[Random.Range(0, nodes.Count)]);
currentPath[0].SetState(NodeState.Current);
while (completedNodes.Count < nodes.Count)
{
//Check nodes next to the current node
List<int> posnexNodes = new List<int>();
List<int> posdirectionNodes = new List<int>();
int currentNodeIndex = nodes.IndexOf(currentPath[currentPath.Count - 1]);
int currentNodeX = currentNodeIndex / size.y;
int currentNodeY = currentNodeIndex % size.y;
if (currentNodeX < size.x - 1) //checking if it's on the rigt wall
{
if (!completedNodes.Contains(nodes[currentNodeIndex + size.y]) &&
!currentPath.Contains(nodes[currentNodeIndex + size.y]))
{
posdirectionNodes.Add(1);
posnexNodes.Add(currentNodeIndex + size.y);
}
}

if(!completedNodes.Contains(nodes[currentNodeIndex - size.y]) &&

posdirectionNodes.Add(2);
posnexNodes.Add(currentNodeIndex - size.y);
}
}

{
if (!completedNodes.Contains(nodes[currentNodeIndex + 1]) &&
!currentPath.Contains(nodes[currentNodeIndex + 1]))
{
posdirectionNodes.Add(3);
posnexNodes.Add(currentNodeIndex + 1);
}
}
if(currentNodeY > 0) //Check node below current node
{

{
posdirectionNodes.Add(4);
posnexNodes.Add(currentNodeIndex - 1);
}
}
if(posdirectionNodes.Count > 0) //Choose next node
{
int chosenDirection = Random.Range(0, posdirectionNodes.Count);
mazenode chosenNode = nodes[posnexNodes[chosenDirection]];
switch (posdirectionNodes[chosenDirection])
{
case 1:
chosenNode.Removewall(1);
currentPath[currentPath.Count - 1].Removewall(0);
break;
case 2:
chosenNode.Removewall(0);
currentPath[currentPath.Count - 1].Removewall(1);
break;
case 3:
chosenNode.Removewall(3);
currentPath[currentPath.Count - 1].Removewall(2);
break;
case 4:
chosenNode.Removewall(2);
currentPath[currentPath.Count - 1].Removewall(3);
break;
}
currentPath.Add(chosenNode);
chosenNode.SetState(NodeState.Current);
}
else
{
completedNodes.Add(currentPath[currentPath.Count - 1]);
currentPath[currentPath.Count - 1].SetState(NodeState.Completed);
currentPath.RemoveAt(currentPath.Count -1);
}
yield return new WaitForSeconds(0.05f);
}
}
}
There is no errors in my compiler, when it runs all it does is give me the following image:
If I take out these lines of code in both the mazenode.cs and mazegenerator.cs the following image is what I get
public void Removewall(int walltoremove)
{
walls[walltoremove].gameObject.SetActive(false);
}
switch (posdirectionNodes[chosenDirection])
{
case 1:
chosenNode.Removewall(1);
currentPath[currentPath.Count - 1].Removewall(0);
break;
case 2:
chosenNode.Removewall(0);
currentPath[currentPath.Count - 1].Removewall(1);
break;
case 3:
chosenNode.Removewall(3);
currentPath[currentPath.Count - 1].Removewall(2);
break;
case 4:
chosenNode.Removewall(2);
currentPath[currentPath.Count - 1].Removewall(3);
break;
}
