Unity中特定项目的C＃编码问题

Question

I'm making a simple game for a school project using Unity. The purpose of the game is to control a ball and pick up coins. The game has 3 scenes. I have written some code in C# to count my pick up coins and set a condition to check if all coins are picked up, if so, a wintext appears at the center of the screen. It works just fine for the first scene (lvl1) but not for the other 2. All 3 scenes have a different ammount of coins. C# is new to me and I have tried various combinations but it hasn't worked. How do I re-write this code so that the wintext appears after I pick up the right ammount of coins on every scene/level? This is my code:

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

public class PlayerController : MonoBehaviour
{

    public float speed;
    public Text countText;
    public Text winText;

    private Rigidbody rb;
    private int count;

    void Start()
    {
        rb = GetComponent<Rigidbody>();
        count = 0;
        SetCountText();
        winText.text = "";

    }

    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        Vector3 movement = new Vector3(moveHorizontal, 0.0f, moveVertical);

        rb.AddForce(movement * speed);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.CompareTag("Pick Up"))
        {
            other.gameObject.SetActive(false);
            count = count + 1;
            SetCountText();

        }
    }

    void SetCountText()
    {
        countText.text = "Coins: " + count.ToString();
        if (count >= 2)
        {
            winText.text = "You Win!";
        }

    }

}

Answer 1

Make a new public variable

...
public float speed;
public Text countText;
public Text winText;
public int numberOfCoinsToWin;
... 

remember to set this new value in the editor for each scene

Use the variable in your condition.

if (count >= numberOfCoinstoWin)
{
    winText.text = "You Win!";
}

Sounds like you're lacking a very basic understanding of C# and programming in general. Here are somethings you could research to make life easier for you:

• variables
• control flow
• access modifiers
• classes (in computer science)
• object orientation

Also using Unity to learn C# is not great. You will miss a lot of fundamentals. I suggest learning C# without unity for a week or 2 and coming back.

Answer 2

This code snippet would dynamically set win condition based on scene, however it would be better if the scene could hold coinToCollect variable.

void SetCountText()
{
    countText.text = "Coins: " + count.ToString();
    int coinsToCollect = 0;
    switch( /* get current scene here */)
    {
        case "scene1": // repeat for other scenes
            coinsToCollect = 2;
            break;
    }
    if (count >= coinsToCollect)
    {
        winText.text = "You Win!";
    }

}
