Adding 2D button behaviors
Now that we can stock our shop and purchase items from it, we just need the ability for
users to buy items when selected, so create a new script named
BuyButton
and place it
in
Assets\Scripts\Shop
with the following contents:
using UnityEngine;
public class BuyButton : MonoBehaviour {
void OnMouseDown()
{
ShopManager.PurchaseSelectedItem();
}
}
The preceding code simply calls the static
Purchasing
function we created in the
ShopManager
script earlier to buy an item on any game object that has a 2D collider
placed on it, as we did with the
ShopSlot
script.
