Hey! Im a beginner and need help in randomizing. (Im making a 2d game in Unity)

Questions & Answers

So this is my code which spawns a triangle to one of three points. On the last line (Instantiate(triangle…) I would like to randomize the “triangle” to be triangle, triangle1 or triangle2 and I have no idea how. Please help :slight_smile:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RandomChoose : MonoBehaviour
{
public Transform points;
public float InvokeRate = 1.0f;
public GameObject triangle;
public GameObject triangle1;
public GameObject triangle2;

void Start()
{
    InvokeRepeating("pickpoints", 1.0f, InvokeRate);
}

void pickpoints()
{
    int indexNumber = Random.Range(0, points.Length);
    Instantiate(triangle, points[indexNumber].position, triangle.transform.rotation);
}

}

Same thing you were doing with the points, just throw each triangle into an array and calculate a random index

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class RandomChoose : MonoBehaviour {
    public Transform[] points;
    public float InvokeRate = 1.0f;
    public GameObject triangle;
    public GameObject triangle1;
    public GameObject triangle2;

    private GameObject[] triList;

    void Start () {
        triList = new GameObject[3];
        triList[0] = triangle;
        triList[1] = triangle1;
        triList[2] = triangle2;

        InvokeRepeating ("pickpoints", 1.0f, InvokeRate);
    }
    void pickpoints () {
        int indexNumber = Random.Range (0, points.Length);
        GameObject triangleToSpawn = triList[Random.Range(0, triList.Length)];
        Instantiate (triangleToSpawn, points[indexNumber].position, triangle.transform.rotation);
    }
}
