New to Unity C# coding. I'm writing a script to achieve procedural generation in a 2D roguelike game. My idea is to use enum to represent 4 directions (up, down, left, right), then pick a random direction to produce a room from Prefab. Then next room will be generated by the same method. Here are my codes:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class RoomGenerator : MonoBehaviour
{
public enum Direction { up, down, left, right };
public Direction direction;
[Header("Room Information")]
public GameObject roomPrefab;
public int roomNumber;
public Color startColor, endColor;
[Header("Position Controller")]
public Transform generatorPoint;
public float xOffset;
public float yOffset;
public List<GameObject> rooms = new List<GameObject>();
void Start()
{
for (int = 0; i < roomNumber, int++)
{
rooms.Add(Instantiate(roomPrefab, transform.position, Quaternion.identity));
ChangePointPosition();
}
}
void Update()
{
}
public void ChangePointPosition()
{
direction = (Direction)Random.Range(0,4);
switch(direction)
{
case Direction.up:
generatorPoint.position += new Vector3 (0, yOffset, 0);
break;
case Direction.down:
generatorPoint.position += new Vector3 (0, -yOffset, 0);
break;
case Direction.left:
generatorPoint.position += new Vector3 (-xOffset, 0, 0);
break;
case Direction.right:
generatorPoint.position += new Vector3 (xOffset, 0, 0);
break;
}
}
}
Unity is saying "error CS1525: invalid expression term 'int'". How's that possible? Did I miss something? Please help. Thanks in advance!
