选择要在Unity中加载的保存文件? [英] Choosing which save file to load in Unity?

问题描述

因此，我已经设法设置了程序以使用任何文件名进行保存，而且我已经很容易能够在foreach循环中将它们全部选中.如何从那里在Unity 中使用这些保存文件填充Scroll View列表?就像这样:

So, I've already managed to set up the program to save with any filename, and I'm already easily able to pick them all up in a foreach loop. How can I, from there, populate a Scroll View list in Unity with those save files? Like, something like this:

每个保存文件在滚动视图"中占据一行，可以选择其中的一个，您可以点击加载游戏"，然后加载.

where every save file would take up a line in the Scroll View, one could be selected, you could hit 'load game', and it would load.

推荐答案

这里是一个简短的教程，介绍了如何做到这一点:

Here is a short tutorial how to do this:

DynamicScrollView.cs

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

public class DynamicScrollView : MonoBehaviour 
{
    public GameObject Prefab;
    public Transform Container;
    public List<string> files = new List<string>();

    void Start()
    {
//      files =  // LOAD FILE NAMES HERE.

        for (int i = 0; i < files.Count; i++)
        {
            GameObject go = Instantiate(Prefab);
            go.GetComponentInChildren<Text>().text = files[i];
            go.transform.SetParent(Container);
            go.transform.localPosition = Vector3.zero;
            go.transform.localScale = Vector3.one;
            int buttonIndex = i;
            go.GetComponent<Button>().onClick.AddListener(() => OnButtonClick(buttonIndex));
        }
    }



    public void OnButtonClick(int index)
    {
        string file = files[index];

        Debug.Log(file);
        // Process file here...
    }
}
