random array instance
Hello
I want to do a quiz that changes after a wrong answer. Is about a question about a geometric object of the game with 3 buttons. I can load the geometry that i put array of the component but now i want to load it random.
This is my script.
using UnityEngine;
using System.Collections;
public class desafio1 : MonoBehaviour {
public GUIStyle certa;
public GUIStyle errada1;
public GUIStyle errada2;
public GUIStyle rotulo;
public GameObject[] predios;
public GameObject loadPredios;
string rotulo_erro;
Random randomNumber = new Random();
// Use this for initialization
void Start () {
loadPredios = Instantiate(predios[0],transform.position,Quaternion.identity)as GameObject;
}
// Update is called once per frame
void Update () {
}
void OnGUI()
{
GUI.Label(new Rect(0,100,800,50),rotulo_erro,rotulo);
if(GUI.Button(new Rect(300, 50, 56,56), "", certa )){
Application.LoadLevel("level2");
}
if(GUI.Button(new Rect(380, 50, 56,56), "", errada1 )){
rotulo_erro = "OPS";
Destroy(loadPredios);
}
if (GUI.Button(new Rect(460, 50, 56,56), "", errada2 )){
rotulo_erro = "WRONG";
Destroy(loadPredios);
loadPredios = Instantiate(predios[0],transform.position,Quaternion.identity)as GameObject;
}
}
}
If you are trying to use System.Random:
int rnd = randomNumber.Next(predios.Length);
loadPredios = Instantiate(predios[rnd],transform.position,Quaternion.identity)as GameObject;
But you look to be missing a using System; in this case.
If you mean to use Unity Random, remove your randomNumber declaration and use:
int rnd = Random.Range(0,predios.Length);
If just want to select a building among the array elements, you can use Random.Range(0, array.Length) as the index - it returns a number from 0 to array.Length-1:
using UnityEngine; using System.Collections;
public class desafio1 : MonoBehaviour { public GUIStyle certa; public GUIStyle errada1; public GUIStyle errada2; public GUIStyle rotulo; public GameObject[] predios; public GameObject loadPredios; string rotulo_erro; Random randomNumber = new Random();
// Use this for initialization
void Start () {
loadPredios = Instantiate(predios[Random.Range(0, predios.Length)], transform.position,Quaternion.identity)as GameObject;
}
// Update is called once per frame
void Update () {
}
void OnGUI(){
GUI.Label(new Rect(0,100,800,50),rotulo_erro,rotulo);
if(GUI.Button(new Rect(300, 50, 56,56), "", certa )){
Application.LoadLevel("level2");
}
if(GUI.Button(new Rect(380, 50, 56,56), "", errada1 )){
rotulo_erro = "OPS";
Destroy(loadPredios);
}
if (GUI.Button(new Rect(460, 50, 56,56), "", errada2 )){
rotulo_erro = "WRONG";
Destroy(loadPredios);
loadPredios = Instantiate(predios[Random.Range(0, predios.Length)],transform.position,Quaternion.identity)as GameObject;
}
}
}
