We all know how a crafing table from minecrft works, All I’m struggling to do is see if object onje (the draggable object is in one of the nine seperate frapes in the typical tic tac toe format. I have no clue where I’d start so if you could help thank you!

I would like to think you start by creating a table of ingredients. like this;
local ingredientsList = {"Carrot","Apple","Coconut"}
Whatever you do to make things craft you check whether 1 ingredient and another ingredient are the selected ingredients that the player combined together.
function craft(craftedItem)
print("You crafted a "..craftedItem)
end
if selectedObject1 == ingredientsList[1] and selectedObject2 == ingredientsList[2] then
item = "Sword"
craft(item)
end
If they are, then congratulations you have what you crafted.

Sorry, wasnt clear enough, how would I detect whenever the selected item (from example, a hotbar) you’d drag it to this # shaped gui, like the minecraft crafting table. How would I snap the frame into the selected from with a drag motion, then detect what slot the item is on?
Hmm I haven’t tried that before, I would suggest making some sort of loop when you’re dragging it and connecting a function that enables the loop. When you let go the loop will check if you let go and then check the position.X and position.Y and see if they’re <= to the location.
local range = 5 -- the range is like using magnitude kinda but in a gui style
if guiFrameDropped.Position.X <= selectionBox.Position.X + range then
drop()
end
and to snap the gui you just do
guiFrameDropped.Position = selectionBox.Position -- idk if this works but it does for parts

Hm, that seems logical, I’ll test really quick and see if it works 
Awesome, let me know if it works because I’m curious I haven’t done anything like that before.

I don’t guess it works, I’ve got to go to bed now for school in the morning, I’ll keep experimenting tomorrow, though!
Awesome! So does that mean it works or no?
It doesn’t, sadly, I’m going to try fixing it tomorrow, though.
You could drag the item, and once it is released, place it in the nearest square(calculate which square is the nearest).
Have the draggable item having some kind of name tag that you can use to indentify it as one, E.g you could name the frame “Carrot”.
You could then loop through the squares and check what item’s inside, if it matches any setting then proceed on craft it. I don’t think you can simply check if it has a X shape, you would have to define it on your script.
E.g
-- the recipe
local cakeRecipe = {
a1= "wheat", a2="wheat", a3="wheat", b1="egg",b2="sugar", b3="egg",c1="milk", c2="milk", c3="milk"}
-- what currently is being displayed on the crafting table
local onGrid = {a1= "wheat", a2="wheat", a3="wheat", b1="egg",b2="sugar", b3="egg",c1="milk", c2="milk", c3="milk"}
-- debug value used later
local matches = true
-- we loop through the grid and compare it to the recipe
for index,item in pairs(onGrid) do
if(not cakeRecipe[index] == item)then
-- they don't match
matches = false
end
wait() -- we use wait() to wait the loop to finish
end
-- in the end, if it matches the recipe, we craft the item
-- I simply used print() for testing reasons
if(matches == true) then
print("Craft cake")
end
Here I used the minecraft cake recipe as an example, you could do anything.
Imagine the horizontal lines as numbers and the verticals as letters, similar to table games.
It may not be the faster way to do it but works, and hopefully helps you developing your system.
If there’s something you don’t understand, feel free to ask me, and I’ll try to help the best that I can!

Are you trying to make Minecraft in roblox?
minecraft on roblox is illegal!
on my phone driving across country rn but lets see if i can help. In my old voxel project when i was learning lua i did something like this:
item/recipe module:
return(
recipe = {3,3,3,0,2,0,0,2,0}; --[[pickaxe, 3 being id for stone and 2 being id of stick, 0 is nil/blank]]–
)
so if you’re trying to make minecraft, the crafting grid would be set the same way, just a table with ids and when plr changes an id search the recipes and see if it matches any.
sorry if i dont make any sense. lol
just read the thread a bit more. i used mousehover for moving slots around in inventory.
What is specifically illegal about Minecraft in Roblox?
Minecraft is one of the few games that requested to not have content made of its game on Roblox, this includes several other games, but Minecraft is one that requested this. Roblox legally has to take down any game that has Minecraft assets.
Oh ok, are you able to make a game that doesn’t use minecraft assets but is similar in concept?
I am not really sure, you’d have to check with Roblox themselves, as I can’t determine or tell you an accurate answer to that.
I appreciate the explanation! Thank you!
