StoreGUI problems

Donovan_Rucastle · February 23, 2013, 8:09am

Hi guys

I was wondering if anyone could help me ? I found this code the other day and I have been messing around with it but as I don’t know C# well I don’t really know what to do ?

I would like to add the functionality of being able to instantiate a prefab when I have selected the item and bought it ? I guess I would have to add a third array referencing to the other two arrays in that category and then add some code in Additemtoinventory function ( it’s already there) but how would I do this ?

And one last thing I’m sorry I know this is a large request but can I make the prefab spawn as the child of my empty game object called spawn point ?

Please could someone help ?
It would mean a lot !!

This is the script ! If anyone could format it for me that would be great as I am typing on an ipad and cannot do that!

4- Chegue perto do Prefab e clique nele para mostrar a loja
5- Afaste-se e ela fecha sozinha

If you simply want to instantiate the item then you need to have prefabs that match the selectedItem text.

Create a prefab called Blade Of Chaos
Select the “Blade Of Chaos” in the store
Click “Buy”

in the addItemToInventory() function (assuming your SpawnPoint object exists)

GameObject newItem = (GameObject)Instantiate((GameObject)Resources.Load(selectedItem), SpawnPoint.transform.position, SpawnPoint.transform.rotation);

Then to set the spawn point as the parent

newItem.transform.parent = SpawnPoint.transform;

Let me know if I missed something.
