How would I make a player backpack? with a capacity count?

This is tough, do you want it like if there are too many tools in the Roblox backpack the player will equip the tool it tried to store in their backpack?

CurrentCapacity/MaxCapacity returns a value between 0 and 1 which can be used to scale the frame.

If a player touched an object, how would I make the game make it so that the player gets 1+ of their Current Capacity? How would I know/detect what player was it that equipped it?

and also, is there a way I can attach this to a player if they click a equip button?

How would I save the players backpack capacity and what type of backpack they have?

You can google how to do those things. I’m pretty sure the api covers most of your questions.

You can store every player in a list when they join. Make a local script and check if the objects were touched by the local player. If so, fire a remote event to the server and increase the value in the list by 1. Attach the touched objects by making a RigidConstraint if they trigger a ProximityPrompt. To save backpacks, use the DataStoreService.

For your first question, you can store an IntValue inside the player (Which you might also use for datastore), and increment it whenever the player touched it.

You don’t need to detect what player equipped it. You can simply do something like this. If you are storing the touchable parts in a model or folder you can just put this script in the model/folder.

local Players = game:GetService('Players')
local Folder = script.Parent

for i, Part in pairs(Folder:GetChildren()) do
    Part.Touched:Connect(function(Hit)
        if Hit.Parent:FindFirstChild('HumanoidRootPart') then
            local Character = Hit.Parent
            local Player = Players:GetPlayerFromCharacter(Character)
            local CurrentCapacity = Player.CurrentCapacity --// the int value inside the player
            local Backpack = Character:FindFirstChild('Backpack')
            local MaxCapacity = Backpack.MaxCapacity --// int value in the backpack

            if CurrentCapacity.Value < MaxCapacity.Value then
                CurrentCapacity.Value = CurrentCapacity.Value + 1
            end
        end
    end
end

To attach it to a player, just have an invisible part (green in my example) that tells you where the backpack should be relative to the player, make it the primary part, then whenever you need to, do Backpack:SetPrimaryPartCFrame() and then put in the CFrame of the HumanoidRootPart. After that you can create a weld between the backpack root part and the humanoidrootpart using weldconstraint.

If you’re wondering what the Weld script is, it’s just a script that welds everything in the folder/model to the Root.Value, to make it just paste in the code below and add an ObjectValue called Root.

local Folder = script.Parent
local Root = script.Root.Value

for i, Instance_ in pairs(Folder:GetChildren()) do
	if Instance_:IsA('BasePart') then
		local Weld = Instance.new('WeldConstraint', Instance_)
		Weld.Part0 = Instance_
		Weld.Part1 = Root
	end
end

What is the folder for in the Weld script and this script?

It doesn’t have to be a folder, just set the ObjectValue called “Root” to RootPart

#14 
game.Players.PlayerAdded:Connect(function(Player)
	Player.Backpack.ChildAdded:Connect(function()
		
		print(#Player.Backpack:GetChildren()) -- Value
		
	end)
	
	Player.Backpack.ChildRemoved:Connect(function()
		
		print(#Player.Backpack:GetChildren()) -- Value
	end)
	
end)

And for the other script you just have to put it in the model/folder of objects you want to touch

#16

He doesn’t mean Player.Backpack, he’s talking about the ones used in Bee Swarm Simulator

Im not following, would RootPart be HumanoidRootPart? Or the Primary Part of the Backpack

It would be the primary part of the backpack

Okay lets start from making the backpack first, let me change the script so you don’t need the ObjectValue anymore.

local Model = script.Parent
local Root = Model.RootPart

for i, Instance_ in pairs(Model:GetChildren()) do
	if Instance_:IsA('BasePart') then
		local Weld = Instance.new('WeldConstraint', Instance_)
		Weld.Part0 = Instance_
		Weld.Part1 = Root
	end
end

Bad idea, exploiters can easily spam the remote and get infinite currency. You need to check the touched event on the server.
