Crafting System

Bahaa · September 11, 2023, 10:55am

Hi all. Alright so I read this blog regarding creating a Crafting system, but there are some scripts missing from the blog (as far as I have read), and I can’t figure a way out to properly implement what it says (and the git link at the end of the tutorial is broken). Can we have a remake of this tutorial? It would be highly appreciated

That’s not one of mine. I can add it to my list, but it’s a major system, so it won’t be for a while.

That’s fair. I’m willing to wait, your projects are always top notch

Hello again Brian. Any updates about this one?

Brian_Trotter · September 16, 2023, 3:37am

Not yet. It’s fairly complicated.
As the original tutorial was written when the only two courses in the series were Core Combat and Inventory, there are some structural differences that need to be resolved.

No worries, thank you for taking my suggestion into consideration

Hi Brian, I found this relevant to the Crafting System. Figured it might be helpful:

github.com

eviathan/Unity-Crafting-Example/blob/main/CraftingTable.cs

using System;
using System.Linq;
using UnityEngine;

public class CraftingTable : MonoBehaviour
{
    public TCraftableItem Craft<TCraftableItem>(ICraftingSource craftingSource)
        where TCraftableItem : ICraftable, new()
    {
        if(!CanCraft<TCraftableItem>(craftingSource))
            throw new ArgumentOutOfRangeException($"Could not craft {typeof(TCraftableItem)}");

        var item =  new TCraftableItem();

        foreach (var ingredient in RecipeBook.Recipes[typeof(TCraftableItem)])
            craftingSource.Inventory.TryUse(ingredient.Key, ingredient.Value);
        
        craftingSource.Inventory.Add<TCraftableItem>();

        return item;

This file has been truncated. show original

Can you please have a look and give me your thoughts? (I tried it on my own, but there’s a clash between his inventory and ours…)

As it wasn’t written to fall into our system, it’s not going to be terribly helpful.

This is still on the back burner, I have a lot of irons in the fire (and you do too).

You might try taking this to the Discord and seeing what others in the RPG forum might come up with.

OK so my priority right now is to fix 2 bugs:

The main bug is my ‘Resume’ button leads to a black (black for me) screen and never goes back to the normal alpha value (i.e: doesn’t show me the game). From the debugger and my mouse UI, the game works… just the screen stays black due to a Respawner issue. I’ll paste the stack trace below:

NullReferenceException: Object reference not set to an instance of an object
RPG.Respawnables.RespawnManager.Respawn () (at Assets/Project Backup/Scripts/Respawnables/RespawnManager.cs:103)
RPG.Respawnables.RespawnManager.Start () (at Assets/Project Backup/Scripts/Respawnables/RespawnManager.cs:47)

second bug is that if I save and quit my game to the main menu, and then I return, if I actually see the screen, there’s the loot I forgot to pick up prior to saving my game, just 10x more or so. It’s both resource wasting and unwanted in my game, if I were to keep the game fair and square

Which are unrelated to the crafting system, so should not be here…

Bahaa · September 24, 2023, 6:57pm

Alright I’ll open a new question for them, apologies

Brian_Trotter · September 24, 2023, 6:59pm

Don’t forget that in addition to that stack trace, I have NO idea which line is 103, so I’ll probably need the scripts, as well.

Bahaa · September 24, 2023, 7:02pm

Will put that right away in the new post

Edit: here is the link: 2 Major Bugs

Bahaa · October 13, 2023, 11:10am

I’ll give this a try solo first, then ask for help…

Bahaa · November 2, 2023, 10:23am

Ahh I finished this a while ago…
