Minecraft-style CRAFTING SYSTEM in Unity

This is a tutorial for a Minecraft-style crafting system in Unity. It uses Scriptable Objects to define items and recipes with a 3x3 grid for the crafting table.

Compare your code to mine ;)

There has been a bug identified in this system (thanks to emperorLine). Please check the GitHub in the description for the updated RecipeManager. Without this, the system may not work as intended.

So I fixed my other problems but why doesn't the output show when I craft it
please help me
also it doesn't show the sprite in any other slot than the one it was previously in

[narwhaale]

what are the variables set in the itemSlot in the crafting output in the itemSlot script

[Gonzo]

This is the only crafting system that actually worked for me thank you just two questions when i move the item from the output slot it doesnt follow my mouse like the other slots how would i fix this, and i want the items in the crafting grid to be destroyed when i grab the item out of the output slot how would i do this?

hey, could anyone help me with showing the item in the output slot on dragging please?

[RandallGranger]

im encountering a problem while trying this system out

using multiple recipes causes the output to be empty when a new recipe uses the same components as an older recipe
(for example, 2 sticks and a diamond dont make a shovel anymore when there's a recipe for a diamond sword using 1 stick and 2 diamonds)

any ideas for a fix?

[PanMaciejK]

Just, doesn't work. Built it with tutorial 1 to 1 -> not working
Took code from Git, still nothing, even more problems. Scripts are marked as having syntax problems, even tho Visual Studio says they're okay.

[redstoneengineer]

it says canvas group in itemSlot isnt a thing you can use?

[littleoaklings]

Would this be easy to implement with other inventory systems?

[redstoneengineer]

When I try the ItemSO Script it says "ItemSo will be ignored because it is not attached to a scriptible object" Any help?

[olivermetz]

could this be touchscreen/ mobile compatible?

[beso.]

it can be crafted multiple times, how do I make it so it can only happen once?
