③处理角色面板的物品槽类（EquipmentSlot），继承自Slot类：
using UnityEngine;
using System.Collections;
using UnityEngine.EventSystems;
///
/// （ Slot： ）， 。
///
public class EquipmentSlot :Slot
{
public Equipment.EquipmentType equipmentSoltType;// 。 ， ， ， ， 。 。
public Weapon.WeaponType wpType;// ， ， Null
public override void OnPointerDown(UnityEngine.EventSystems.PointerEventData eventData)// Slot
{
if (eventData.button == PointerEventData.InputButton.Right)// ，
{
if (transform.childCount > 0 && InventroyManager.Instance.IsPickedItem == false)// ， ， ： ， 。
{
ItemUI currentItemUI = transform.GetChild(0).GetComponent();
Item item = currentItemUI.Item;// ，
DestroyImmediate(currentItemUI.gameObject);//
transform.parent.SendMessage("PutOff", item);// （ ）
InventroyManager.Instance.HideToolTip();//
}
}
if (eventData.button != PointerEventData.InputButton.Left) return; //
// ：
// ：
//1.
//2.
// ：
//1.
//2. （ ）
bool isUpdataProperty = false;//
if (InventroyManager.Instance.IsPickedItem == true)// ：
{
ItemUI pickedItemUI = InventroyManager.Instance.PickedItem;//
if (transform.childCount > 0)//1.
{
ItemUI currentItemUI = transform.GetChild(0).GetComponent();//
if (IsRightItem(pickedItemUI.Item) && pickedItemUI.Amount == 1)// ， ，
{
pickedItemUI.Exchange(currentItemUI);
isUpdataProperty = true;//
}
}
else//2.
{
if (IsRightItem(pickedItemUI.Item))// ， ， ，
{
this.StoreItem(pickedItemUI.Item);
InventroyManager.Instance.ReduceAmountItem(1);
isUpdataProperty = true;//
}
}
}
else// ：
{
if (transform.childCount>0) //1. ， ，
{
ItemUI currentItemUI = transform.GetChild(0).GetComponent();
InventroyManager.Instance.PickUpItem(currentItemUI.Item, currentItemUI.Amount);
Destroy(currentItemUI.gameObject);
isUpdataProperty = true;//
} //2. （ ）
}
if (isUpdataProperty == true)
{
transform.parent.SendMessage("UpdatePropertyText");
}
}
//
public bool IsRightItem(Item item)
{
if ((item is Equipment && ((Equipment)(item)).EquipType == this.equipmentSoltType) || (item is Weapon && ((Weapon)(item)).WpType == this.wpType))// ， ， 。
{
return true;
}
else
{
return false;
}
}
}
④处理商店购买物品面板的物品槽类（VendorSlot），同样继承自Slot类：
using UnityEngine;
using System.Collections;
public class VendorSlot : Slot {
// Slot ， ， ，
public override void OnPointerDown(UnityEngine.EventSystems.PointerEventData eventData)
{
if (eventData.button == UnityEngine.EventSystems.PointerEventData.InputButton.Right)//
{
if (transform.childCount > 0 && InventroyManager.Instance.IsPickedItem == false)// ,
{
Item currentItem = transform.GetChild(0).GetComponent().Item;//
transform.parent.parent.SendMessage("BuyItem",currentItem);
}
}
else if (eventData.button == UnityEngine.EventSystems.PointerEventData.InputButton.Left && InventroyManager.Instance.IsPickedItem == true)//
{
transform.parent.parent.SendMessage("SellItem");
}
}
}
⑤物品UI処理類(ItemUI):
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class ItemUI : MonoBehaviour
{
public Item Item { get; private set; } //UI
public int Amount { get; private set; }//
private Image itemImage;// item Image
private Text amountText;// item
private float targetScale = 1f;//
private Vector3 animationScale = new Vector3(1.4f, 1.4f, 1.4f);
private float smothing = 4f;//
void Awake() // get
{
itemImage = this.GetComponent![]()
();
amountText = this.GetComponentInChildren();
}
void Update()
{
if (this.transform.localScale.x != targetScale)//
{
float scaleTemp = Mathf.Lerp(this.transform.localScale.x, targetScale, smothing*Time.deltaTime);
this.transform.localScale = new Vector3(scaleTemp, scaleTemp, scaleTemp);
if (Mathf.Abs(transform.localScale.x-targetScale) < 0.02f)// ， ，
{
this.transform.localScale = new Vector3(targetScale, targetScale, targetScale);
}
}
}
///
/// item UI ， 1
///
///
public void SetItem(Item item, int amount = 1)
{
this.transform.localScale = this.animationScale;// UI，
this.Item = item;
this.Amount = amount;
this.itemImage.sprite = Resources.Load(item.Sprite); // UI
if (this.Amount > 1)
{
this.amountText.text = Amount.ToString();
}
else
{
this.amountText.text = "";
}
}
///
/// item
///
///
public void AddItemAmount(int num = 1)
{
this.transform.localScale = this.animationScale;// UI，
this.Amount += num;
if (this.Amount> 1)// UI
{
this.amountText.text = Amount.ToString();
}
else
{
this.amountText.text = "";
}
}
// item
public void SetAmount(int amount) {
this.transform.localScale = this.animationScale;// UI，
this.Amount = amount;
if (this.Amount > 1)// UI
{
this.amountText.text = Amount.ToString();
}
else
{
this.amountText.text = "";
}
}
//
public void RemoveItemAmount(int amount = 1)
{
this.transform.localScale = this.animationScale;// UI，
this.Amount -= amount;
if (this.Amount > 1)// UI
{
this.amountText.text = Amount.ToString();
}
else
{
this.amountText.text = "";
}
}
//
public void Show() {
gameObject.SetActive(true);
}
//
public void Hide() {
gameObject.SetActive(false);
}
//
public void SetLocalPosition(Vector3 position)
{
this.transform.localPosition = position;
}
// （UI） （UI）
public void Exchange(ItemUI itemUI)
{
Item itemTemp = itemUI.Item;
int amountTemp = itemUI.Amount;
itemUI.SetItem(this.Item, this.Amount);
this.SetItem(itemTemp, amountTemp);
}
}
⑥情報提示枠類(Tooltip)、提示枠の各種機能を処理する:
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
///
///
///
public class ToolTip : MonoBehaviour {
private Text toolTipText;// Text，
private Text contentText;// Text，
private CanvasGroup toolTipCanvasGroup;// CanvasGroup ，
private float targetAlpha = 0.0f ;// Alpha ，0 ，1
public float smothing = 1.0f;//
void Awake()
{
toolTipText = this.GetComponent();
contentText = this.transform.Find("Content").GetComponent();
toolTipCanvasGroup = this.GetComponent();
}
// Update is called once per frame
void Update () {
if (toolTipCanvasGroup.alpha != targetAlpha)
{
toolTipCanvasGroup.alpha = Mathf.Lerp(toolTipCanvasGroup.alpha, targetAlpha, smothing*Time.deltaTime);
if (Mathf.Abs(targetAlpha - toolTipCanvasGroup.alpha) < 0.01f)// Alpha Alpha ，
{
toolTipCanvasGroup.alpha = targetAlpha;
}
}
}
//
public void Show(string text)
{
this.toolTipText.text = text;
this.contentText.text = text;
this.targetAlpha = 1;
}
//
public void Hide()
{
this.targetAlpha = 0;
}
//
public void SetLocalPosition(Vector3 postion)
{
this.transform.localPosition = postion;
}
}
⑦模擬主役行為類(Player):
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
///
///
///
public class Player : MonoBehaviour {
// ：
private int basicStrength = 10;
public int BasicStrength { get { return basicStrength;} }//
private int basicIntellect = 10;
public int BasicIntellect { get { return basicIntellect; } }//
private int basicAgility = 10;
public int BasicAgility { get { return basicAgility; } }//
private int basicStamina = 10;
public int BasicStamina { get { return basicStamina; } }//
private int basicDamage = 10;
public int BasicDamage { get { return basicDamage; } }//
private Text coinText;// Text
private int coinAmount = 100;// ，
public int CoinAmount {
get { return coinAmount; }
set { coinAmount = value; coinText.text = coinAmount.ToString(); }
}
// Use this for initialization
void Start () {
coinText = GameObject.Find("Coin").GetComponentInChildren();
coinText.text = coinAmount.ToString();
}
// Update is called once per frame
void Update () {
// G
if (Input.GetKeyDown(KeyCode.G))
{
int id = Random.Range(1, 23);
Knapscak.Instance.StoreItem(id);
}
// B
if (Input.GetKeyDown(KeyCode.B))
{
Knapscak.Instance.DisplaySwitch();
}
// H
if (Input.GetKeyDown(KeyCode.H))
{
Chest.Instance.DisplaySwitch();
}
// V
if (Input.GetKeyDown(KeyCode.V))
{
CharacterPanel.Instance.DisplaySwitch();
}
// N
if (Input.GetKeyDown(KeyCode.N))
{
Vendor.Instance.DisplaySwitch();
}
// M
if (Input.GetKeyDown(KeyCode.M))
{
Forge.Instance.DisplaySwitch();
}
}
//
public bool ConsumeCoin(int amount)
{
if (coinAmount >= amount)
{
coinAmount -= amount;
coinText.text = coinAmount.ToString();//
return true;//
}
return false;//
}
//
public void EarnCoin(int amount)
{
this.coinAmount += amount;
coinText.text = coinAmount.ToString();//
}
}
