Unity3D（六）揹包系統

我這次只實現了一個相當簡單的揹包系統。就是點擊裝備欄，裝備欄上的貼圖會跟着鼠標走，如果有貼圖的鼠標點擊揹包欄，貼圖就會粘到揹包裏。就是一個簡單的揹包裝備。實現過程也不是很複雜，代碼不是很多，主要是佈置場景。

（而且拖入揹包上的時候圖片無法顯示…至今不知道爲何

代碼如下：
equip.cs

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
using Game_Manager;

public class equip : MonoBehaviour {

    private Game_Scene_Manager gsm;
    private Image equip_image;

    public Color UISprite_color;

    void Awake()
    {
        Debug.Log ("awake...");
        gsm = Game_Scene_Manager.GetInstance();
        equip_image = GetComponent<Image>();
    }

    public void On_equip_Button() {
        int MouseType = gsm.GetMouse().GetMouseType();
        if (equip_image.sprite == weapon && (MouseType == 0 || MouseType == mouse_type))
        {
            equip_image.sprite = UISprite;
            equip_image.color = UISprite_color;
            gsm.GetMouse().SetMouseType(mouse_type);
//          Debug.Log ("SetMouseType : " + gsm.GetMouse().GetMouseType());//test
        }
        else
        {
            if (MouseType == mouse_type) {

                gsm.GetMouse().SetMouseType(0);
            }
        }
    }

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
//      On_equip_Button ();//test
        if (mouse_type == 1 && gsm.GetHair() == 1)
        {
            gsm.SetHair(0);

TiltWindow.cs（Canvas跟着鼠標動，看起來舒服）

using UnityEngine;

public class TiltWindow : MonoBehaviour
{
    public Vector2 range = new Vector2(5f, 3f);

    Transform mTrans;
    Quaternion mStart;
    Vector2 mRot = Vector2.zero;

    void Start ()
    {
        mTrans = transform;
        mStart = mTrans.localRotation;
    }

    void Update ()
    {
        Vector3 pos = Input.mousePosition;

        float halfWidth = Screen.width * 0.5f;
        float halfHeight = Screen.height * 0.5f;
        float x = Mathf.Clamp((pos.x - halfWidth) / halfWidth, -1f, 1f);
        float y = Mathf.Clamp((pos.y - halfHeight) / halfHeight, -1f, 1f);
        mRot = Vector2.Lerp(mRot, new Vector2(x, y), Time.deltaTime * 5f);

        mTrans.localRotation = mStart * Quaternion.Euler(-mRot.y * range.y, mRot.x * range.x, 0f);
    }
}

這裏的格子我都使用了button，比較方便
