1. Ini 配置文件插件

 

2. 读取配置文件人的位置和偏移

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

public class IniRead : MonoBehaviour {
    public string INIPath;
    public static IniRead Instance;
    public float SetPrimaryPlayerPosX;
    public float SetPrimaryPlayerPosZ;
    public float SetPrimaryPlayerPosXOffset;
    public float SetPrimaryPlayerPosZOffset;
    void Awake()
    {
        Instance = this;
        INIPath = Application.streamingAssetsPath + "/Config.ini";
        IniReadFile(INIPath);
    }
    void IniReadFile(string path)
    {
        INIParser iniParser = new INIParser();
        iniParser.Open(path);
        SetPrimaryPlayerPosX = Convert.ToSingle(iniParser.ReadValue("SetPrimaryPlayerPos", "x", 0d));
        SetPrimaryPlayerPosZ = Convert.ToSingle(iniParser.ReadValue("SetPrimaryPlayerPos", "z", 1.8d));
        SetPrimaryPlayerPosXOffset = Convert.ToSingle(iniParser.ReadValue("SetPrimaryPlayerPos", "xOffset", 0.15d));
        SetPrimaryPlayerPosZOffset = Convert.ToSingle(iniParser.ReadValue("SetPrimaryPlayerPos", "zOffset", 0.15d));
        Debug.Log(SetPrimaryPlayerPosX);
        iniParser.Close();
    }
}

3. 正式代码如下:

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

    // Use this for initialization
    void Start()
    {
        if (KinectManager.Instance) _manager = KinectManager.Instance;

    }

    // Update is called once per frame
    /// 

    /// 
    ///

            //bool b = MakeBow(_manager.GetPrimaryUserID());

            //{

运行结果如图:
