读取Assets/Resources/rectData.txt内数据Position: 0, 0, 0Scale: 0, 0, 1Rotation: 0, 0, 1赋值到RectTransform

在Unity中，要从`Assets/Resources/rectData.txt`文件中读取数据并将其中的Position（位置）、Scale（缩放）和Rotation（旋转）信息赋值给RectTransform组件，你需要使用C#脚本。首先确保文本文件是以正确的格式存储这些值，例如每行分别对应position、scale和rotation。

以下是一个简单的示例代码：

using UnityEngine;
using System.IO;

public class AssignResourceValues : MonoBehaviour
{
    public RectTransform rectTransform; // 需要赋值的目标 RectTransform

    void Start()
    {
        string filePath = "Assets/Resources/rectData.txt";
        if (File.Exists(filePath))
        {
            string[] lines = File.ReadAllLines(filePath);
            if (lines.Length >= 3) // 假设文本文件有三行，分别对应position, scale, rotation
            {
                Vector3 position = ParseVector3(lines);
                Vector3 scale = ParseVector3(lines);
                Vector3 rotation = ParseVector3(lines[2]);

                rectTransform.localPosition = position;
                rectTransform.localScale = scale;
                rectTransform.localRotation = Quaternion.Euler(rotation); // 注意：Unity中的本地旋转是Quaternion，不是Euler angles直接用
            }
            else
            {
                Debug.LogError("Text file format is incorrect. Expected three values per line.");
            }
        }
        else
        {
            Debug.LogError("Text file not found at path: " + filePath);
        }
    }

    private Vector3 ParseVector3(string vectorString)
    {
        string[] values = vectorString.Split(',');
        float[] floats = new float;
        for (int i = 0; i < 3; i++)
        {
            floats[i] = float.Parse(values[i].Trim());
        }
        return new Vector3(floats, floats, floats);
    }
}
