error en unity C#: Error CS0721: ‘Aleatorio’: los tipos estáticos no se pueden usar como parámetros

– UnityAssets3Free

hola , me llamo juansito y para hoy os traigo
nueva pregunta

Encontré un código en Internet que funciona como el de Python random.choices():

static class RandomUtils

    public static string Choice(this Random rnd, IEnumerable<string> choices, IEnumerable<int> weights)
    
        var cumulativeWeight = new List<int>();
        int last = 0;
        foreach (var cur in weights)
        
            last += cur;
            cumulativeWeight.Add(last);
        
        int choice = rnd.Next(last);
        int i = 0;
        foreach (var cur in choices)
        
            if (choice < cumulativeWeight[i])
            
                return cur;
            
            i++;
        
        return null;
    

Añadido a mi código:

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

public class GroundTile : MonoBehaviour

    GroundSpawner groundSpawner;
    public GameObject player;

    private bool doDoubleSpawn;
    private int chanceForDoubleSpawn = 45;

    void Start()
       
        groundSpawner = GameObject.FindObjectOfType<GroundSpawner>();
        player = GameObject.Find("Tractor");
        SpawnObstacle();
        chanceForDoubleSpawn = GroundSpawner.levelObstaclesMultiplier;
    

    // Spawn weight values for obstacles
    private int boxWeightValue = 40;
    private int antitankWeightValue = 40;
    private int barricadeWeightValue = 40;
    private int wheelsWeightValue = 40;
    private int molotovItemWeightValue = 5;

    // Prefabs
    public GameObject obstaclePrefab;

    public GameObject boxPrefab;
    public GameObject antitankPrefab;
    public GameObject barricadePrefab;
    public GameObject wheelsPrefab;

    public GameObject tankLevel1Prefab;
    public GameObject molotovItemPrefab;

    // Destroy if player too far away
    void Update()
    
        if(transform.position.z < player.transform.position.z - 30)
        
            Destroy(gameObject);
        
    


static class RandomUtils

    public static string Choice(this Random rnd, IEnumerable<string> choices, IEnumerable<int> weights)
    
        var cumulativeWeight = new List<int>();
        int last = 0;
        foreach (var cur in weights)
        
            last += cur;
            cumulativeWeight.Add(last);
        
        int choice = rnd.Next(last);
        int i = 0;
        foreach (var cur in choices)
        
            if (choice < cumulativeWeight[i])
            
                return cur;
            
            i++;
        
        return null;
    

Pero me da error:

AssetsScriptsGroundGeneratorGroundTile.cs(61,30): error CS0721: ‘Random’: los tipos estáticos no se pueden usar como parámetros

¿Cómo puedo corregir eso? ¿Quizás hay otra forma de escribir esta función?

UPD: código que instancia GroundTile:

using UnityEngine;

public class GroundSpawner : MonoBehaviour
{   
    public GameObject groundTile;
    public GameObject groundTileEnd;
    public GameObject player;

    Vector3 nextSpawnPoint;
    private int numOfTiles = 10;
    private int plusTiles = 5;
    private int count = 0;
    public static int level = 1;

    public static int levelObstaclesMultiplier = 45;

    // Weight values for tanks and items
    public static int tankWeightValue = 100;
    public static int molotovItemWeightValue = 10;
    public static int molotovItemWeightValuePlus = 3;


    public void SpawnTile()
    
        GameObject temp = Instantiate(groundTile, nextSpawnPoint, Quaternion.identity);
        nextSpawnPoint = temp.transform.GetChild(1).transform.position;
    

    public void SpawnEndTile()
    
        GameObject temp = Instantiate(groundTileEnd, nextSpawnPoint, Quaternion.identity);
        nextSpawnPoint = temp.transform.GetChild(1).transform.position;
    

    void Start()
    
        for (int i = 0; i < 10; i++)
        
            SpawnTile();
        

        SpawnEndTile();


        InvokeRepeating("Spawn", 1.5f, 1.5f);
    

    public void Spawn()
    
        if (Time.timeScale != 0 && PlayerController.forwardSpeed != 0)
        
            if (count != numOfTiles)
            
                SpawnTile();
                count += 1;
            
            else
            
                SpawnEndTile();
                numOfTiles += plusTiles;
                count = 0;
                if (levelObstaclesMultiplier <= 65)
                
                    levelObstaclesMultiplier += 1;
                
               
        
    
}

Este código parece que fue escrito para C# System.Random en lugar de Unity específico UnityEngine.Random clase. Puede resolver el error especificando System.Random en los parámetros:

public static string Choice(this System.Random rnd, IEnumerable<string> choices, IEnumerable<int> weights)

En los parámetros, simplemente reemplace «Random» con «System.Random», el error se debe a que cree que está usando UnityEngine.Random, que es un tipo estático.

public static string Choice(this System.Random rnd, IEnumerable<string> choices, IEnumerable<int> weights)

nota: si aun no se resuelve tu pregunta por favor dejar un comentario y pronto lo podremos de nuevo , muchas gracias

sin mas,espero que te halla servido
