Why can't I access the public variables of the children class of TestItem in this syntax? I only have access to TestItem variables
//used to retrieve an item by name
Dictionary<string, TestItem> itemDatabase = new Dictionary<string, TestItem>();
//used to retrieve an item by number. great for random item generation
Dictionary<int, TestItem> itemDatabaseInt = new Dictionary<int, TestItem>();
void Start()
{
CreateItemDatabase();
}
void CreateItemDatabase()
{
TestItem item;
item = new TestConsumable();
item.Name = "Health Potion";
item.Icon = Resources.Load<Sprite>("Icons/" + item.Name) as Sprite;
itemDatabase.Add(item.Name, item);
itemDatabaseInt.Add(0, item);
item = new TestConsumable();
item.Name = "Mana Potion";
item.Icon = Resources.Load<Sprite>("Icons/" + item.Name) as Sprite;
itemDatabase.Add(item.Name, item);
itemDatabaseInt.Add(1, item);
item = new TestWeapon();
item.Name = "Short Sword";
item.Icon = Resources.Load<Sprite>("Icons/" + item.Name) as Sprite;
itemDatabase.Add(item.Name, item);
itemDatabaseInt.Add(2, item);
item = new TestShield();
item.Name = "Kite Shield";
item.Icon = Resources.Load<Sprite>("Icons/" + item.Name) as Sprite;
itemDatabase.Add(item.Name, item);
itemDatabaseInt.Add(3, item);
}
The code works and gives me an item database that i can call by name or number just as i wanted. the problem is that, for example, TestWeapon has a public variable called atkType but I can't access it: item.atkType = AtkType.Sword; Every type on this screen inherits from TestItem
To diagnose your problem you need to attach the TestItem script.
using UnityEngine;
using System.Collections;
public class TestBuffItem : TestItem {
Hashtable buff;
public TestBuffItem()
{
//initialize hashtable
buff = new Hashtable();
}
public TestBuffItem(Hashtable ht)
{
buff = ht;
}
public void AddBuff(TestBaseStat stat, int amount)
{
buff.Add(stat.Name, amount);
}
//how many buffs on item
public int BuffCount()
{
return buff.Count;
}
//getters and setters
public Hashtable Buff
{
get { return buff; }
set { buff = value; }
}
}
using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class TestItem {
string _name;
int _value;
Sprite _icon;
//some items just can't be removed from inventory
bool _canBeRemoved;
//private int _descr;
//private int _lore;
public TestItem()
{
_name = "Needs Name";
_value = 0;
_canBeRemoved = true;
_icon = Resources.Load<Sprite>("Icons/Empty") as Sprite;
}
public TestItem(string name, int val, Sprite icon)
{
_name = name;
_value = val;
_canBeRemoved = true;
_icon = icon;
}
#region //getters and setters
public string Name
{
get { return _name; }
set { _name = value; }
}
public int Value
{
get { return _value; }
set { _value = value; }
}
public Sprite Icon
{
get { return _icon; }
set { _icon = value; }
}
public bool CanBeRemoved
{
get { return _canBeRemoved; }
set { _canBeRemoved = value; }
}
#endregion
}
Before I can answer your question I need to know are you having the problem in CreateItemDatabase() or are you having the problem here
_atkType = AttackType.Sword;
inside of TestWeapon()?
the code works fine. i just want to assign the variable _atkType in the CreateItemDatabase() function itself. it creates the items and they are useable in my game but i can't access any variables other thn the TestItem variables. TestWeapon inherits from TestBuffItem which inherits from TestItem but only the TestItem variables are accessible. I can't even add buffs to my weapon or any other TestItem child(TestConsumable inherits TestBuffItem inherits TestItem)
Your problem is that item is your base class and even though this is valid
TestItem item;
item = new TestWeapon();
because TestWeapon is a descendant of TestItem, this is invalid
item.atkType = AtkType.Sword;
because TestItem does not have a member atkType. What you can do however is this
((TestWeapon)item).atkType = AtkType.Sword;
or this
// more preferred
TestWeapon weapon = new TestWeapon();
weapon.atkType = AtkType.Sword;
haha sorry for wasting your time. i knew that but as you can see i have a huge rpg with lots of code and i wanted to not type so much. Was looking for a generic or shortcut but i guess i just gotta stop crying and do more typing lol. thanks for taking the time to follow up. its really appreciated
