Unity position和localposition

1. position是根據世界原點為中心

2. localPosition是根據父節點為中心,如果沒有父節點,localpositon和position是沒有區別的

3.選中一個物體左上角Global和Local切換看物體世界坐標軸和本地坐標軸

 

 

代碼:

using UnityEngine;
using System.Collections;

public class TestPostiton : MonoBehaviour {
    

    void OnGUI() 
    {
        if (GUI.Button(new Rect(0, 0, 200, 50), "世界坐標移動"))
        {
            this.gameObject.transform.position = new Vector3(gameObject.transform.position.x+1
                ,gameObject.transform.position.y
                , gameObject.transform.position.z);
        }

        if (GUI.Button(new Rect(0, 50, 200, 50), "本地坐標移動"))
        {
            this.gameObject.transform.localPosition = new Vector3(gameObject.transform.localPosition.x+1
                , gameObject.transform.localPosition.y 
                , gameObject.transform.localPosition.z);
        }

        GUI.Label(new Rect(210, 0, 300, 50), "世界坐標:" + string.Format("({0},{1},{2})", gameObject.transform.position.x, gameObject.transform.position.y, gameObject.transform.position.z));
        GUI.Label(new Rect(210, 50, 300, 50), "本地坐標:" + string.Format("({0},{1},{2})", gameObject.transform.localPosition.x, gameObject.transform.localPosition.y, gameObject.transform.localPosition.z));


    }
