How do you include a list as a parameter?

[Draconic]

Hi, I am quite new to unity, and have started making an item and skills system for my game. What I have done in my scripts is make each item constructed with 3 parameters (a name, a 2d icon and a 3d texture). Then, each item is given a list of actions that you can do with it. I called them functions in the script, so please don’t get them confused with actual functions! Each new function is added to the list of functions that the item has with 3 parameters, an action type, a magnitude and a list of skills that the action uses.

What I wanted to know is, when I am creating new items, how do I put the list of skills as a parameter? I’m really stuck here, so help would be great !

What I want to do is make a new action, then add it to a list of actions that the item has. Each action has it’s own list, which contains the skills that are used. When I construct an item and it’s actions, I want to have the list as a parameter, so that each time I create an action I create a new list that the action uses.

To put it without the context of my game, if I want to pass have a list as a parameter of a constructor, how do I represent a list when I create a new instance of that class?

Here is the code:

Item script

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
[System.Serializable]

public class Item{
public string itemName;
public Texture2D itemIcon;
public Texture3D itemModel;
public List functions;

public Item(string name){
itemName = name;
itemIcon = Resources.Load(“Item Icons/” + name);
itemModel = Resources.Load(“Item Models/” + name);
//do functions.Add inside the item database. This will be after the new Item.
//each time you create a new item set the item made to a variable, then add the variable.functions.Add();
}
}

//put this in a new script?
public class Function{
public enum functionTypes {
Attack,
Consume
}
public functionTypes functionType;
public float functionMagnitude;
public List functionSkillLine;

public Function(functionTypes type, float magnitude, List skillLine){
functionType = type;
functionMagnitude = magnitude;
functionSkillLine = skillLine;
}
}

Skill script

using UnityEngine;
using System.Collections;
[System.Serializable]
public class Skill{
public string skillName;
public Skill (string name){
skillName = name;
}
}

Skill Database

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

public class SkillDatabase : MonoBehaviour {
public List skills = new List();

void Start(){
skills.Add(new Skill(
“Strength”
));
skills.Add(new Skill(
“Agility”
));
skills.Add(new Skill(
“Intelligence”
));
}
}

Item Database

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

public class ItemDatabase : MonoBehaviour {
public List items = new List();
public int addedCount = 0;
/* Parameters:

• string Name, Texture2D Icon, Texture3D Model
• Functions:
• functionType function, float magnitude, List skillLine
• */

//when changing functionTypes also change this

void Start () {
items.Add(new Item(
“Iron Dagger”
));
addedCount ++;
//replace addedCount with items.Length if can
items[addedCount].functions.Add(new Function(

Function.functionTypes.Attack,
1f
//Add list of skills here

));
}
}

I think you should post some code here, because it’s really hard to help you if we don’t know anything about the structure of your code.

[Diviner]

using System.Collections.Generic;

public class Example {

        public List<Actions> actions;

        public Example (List<Actions> actions) {
                 this.actions = actions;
        }

}

Example example = new Example(new List<Actions>());

Hope that helps.

Hope that helps.

Not really, I’m still confused.
I simply can’t wrap my head around what exactly it is that you want.

Please tell me if I’m correct:
-You have items (as in: certain objects the player can interact with or use)
-All of those items have certain attributes (name, icon, texture) and different sets of actions they can perform

What confuses me the most is the part about the skills.
Are those skills like “skill-requirements”? (You need to unlock/have some skills to use specific actions)

Sorry that I can’t really help you, but the code you provided hasn’t cleared up anything. I’d love to know about the structure of your code. Something like a class diagram would be sweet.
The thing is that while there’s tons of ways to implement the same thing, only a fraction of them is actually good.

You’re quoting an answer from Diviner.

Oops, lol.

Anyway, I’d still love to know more about the surrounding code structure. I just wrote an inventory system myself (with items and all this stuff) and it took me some tries to get it all right. Now I have a system that allows me to implement complex behavior for unique items easily.
Maybe the OP should/could restructure his code.

I edited the post to include my code!

Use the

 tag instead of [QUOTE]. ;)

Anyway.
Including a list as a parameter is as easy as with any type.
[CODE]List<string> example = new List<string>();
example .Add("Stuff");
example .Add("More Stuff");

items[addedCount].functions.Add(new Function(Function.functionTypes.Attack, 1f, example));

However, I think you shouldn’t add the skills in form of a List, but rather List. That way you can’t add nonsense like non-existent skills.
