I am trying to make a product catalog so we can show products, take orders, etc when on different devices and offline to our store.
At the moment I am having trouble passing a instantiated class to another gameobject. I checked some of the similar questions but they did not help me (or I couldn't get them to work with my situation)
The way I have it set up is all through UI elements.
First I have the Product Class that holds all the information for a product:
using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.UI;
public class Product : MonoBehaviour {
public string productName;
public Image productImage;
public string productSKU;
public float productPrice;
public List categories;
}
Then I have a product master where I create all the products:
public class ProductMaster : MonoBehaviour {
public static ProductMaster instance;
public List product; //List to hold all product data
// Use this for initialization
void Awake(){instance = this;}
void Start () {
AddProducts ();
}
void AddProducts()
{
Product Item1 = new Product ();
Item1.productName = "A Ball";
Item1.productSKU = "BALL";
Item1.productPrice = 39.99f;
Item1.productDescription = "Details1,\n followed by details 2";
Item1.productImage = (Image)AssetDatabase.LoadAssetAtPath("Assets/Images/item-1.jpg", typeof(Image));
product.Add (Item1);
Product Item2 = new Product ();
Item2.productName = "Another Ball";
Item2.productSKU = "BALL2";
Item2.productPrice = 19.99f;
Item2.productDescription = "Details1,\n followed by details 2";
Item2.productImage = (Image)AssetDatabase.LoadAssetAtPath("Assets/Images/item-2.jpg", typeof(Image));
product.Add (Item2);
}
}
And so on for all the products.
This all works fine and gets the data into the list.
The next step is that I need to instantiate all the products of a certain category into thumbnails on a canvas.
I do this with the following:
public class CategoryProducts : MonoBehaviour {
ProductMaster PM;
public GameObject productThumbnail;
public Canvas viewPort;
// Use this for initialization
void Start () {
PM = ProductMaster.instance;
}
// Update is called once per frame
void Update () {
if (Input.GetKeyDown ("c"))
FillCategory ("Balls");
}
void FillCategory(string category)
{
foreach (Product p in PM.product) {
GameObject go = Instantiate (productThumbnail) as GameObject; //productThumbnail has a Product Script on it
go.name = p.productName;
go.transform.SetParent (viewPort.transform, false);
go.GetComponent() = p; //THIS IS THE PART THAT DOES NOT WORK. HOW CAN I ASSIGN THE DATA FROM p INTO THE PRODUCT ON THE productThumbnail?
Debug.Log (p.productSKU + " " + p.productName);
}
}
}
The instantiated gameobject from the above code has a product class attached to it that I want to assign the data from the PM.product List but it spits out the error:
The left-hand side of an assignment must be a variable, a property or an indexer
The instantiated object is also a button that when the user presses it, it passes the product data again into a canvas that displays all the information such as productName, productPrice, etc.
How do you pass an instance of a class full of data to another gameobject?
Or is there another way I should be tackling this issue?
I think the best way is for all the parts of the program (there will be 3 canvasses where the same product info need to go to) to reference the one master product list rather than recreating the product in each instance.
