Hello developers,
I recently made a simple hotbar system, and it just works like any other one. Except, it doesn’t update everytime I die or reset my character.
I used the CharacterAdded event at first, it shows me the slot but it gives me this error as well as I can’t equip my tool.
My client code:
game:GetService('StarterGui'):SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)
local plr = game.Players.LocalPlayer
local char = plr.Character
local backpack = plr:WaitForChild("Backpack")
local tools = backpack:GetChildren()
local slotMax = 8
local hotbar = script.Parent
local numToWord =
{
[1] = "One",
[2] = "Two",
[3] = "Three",
[4] = "Four",
[5] = "Five",
[6] = "Six",
[7] = "Seven",
[8] = "Eight"
}
local function updateHotbar()
for i, child in pairs(hotbar:GetChildren()) do
if child.Name == "Slot" then child:Destroy() end
end
for i, tool in pairs(tools) do
if i > slotMax then return end
local slotClone = script.Slot:Clone()
slotClone.HotkeyNumber.Text = i
slotClone.Tool.Image = "rbxassetid://" .. tool.TextureId
slotClone.Parent = hotbar
if tool.Parent == char then
slotClone.BackgroundColor3 = Color3.fromRGB(255, 255, 255)
slotClone.BackgroundTransparency = .25
slotClone:TweenSize(UDim2.new(.924,0,.127,0), "In", "Quad", .25)
else
slotClone.BackgroundColor3 = Color3.fromRGB(255, 255, 255)
slotClone.BackgroundTransparency = .5
slotClone:TweenSize(UDim2.new(.6,0,.25,0), "In", "Quad", .25)
end
game:GetService("UserInputService").InputBegan:Connect(function(input, processed)
if not processed then
if input.KeyCode == Enum.KeyCode[numToWord[i]] then
game.ReplicatedStorage.Events.EquipToolRE:FireServer(tool, tool.Parent)
end
end
end)
end
end
updateHotbar()
backpack.ChildAdded:Connect(function(child)
if not table.find(tools, child) then
table.insert(tools, child)
updateHotbar()
end
end)
backpack.ChildRemoved:Connect(function(child)
if child.Parent ~= char then
table.remove(tools, tools[child])
updateHotbar()
end
end)
plr.CharacterAdded:Connect(function()
char.ChildAdded:Connect(function(child)
if child:IsA("Tool") and not table.find(tools, child) then
table.insert(tools, child)
updateHotbar()
end
end)
char.ChildRemoved:Connect(function(child)
if child.Parent ~= backpack then
table.remove(tools, tools[child])
updateHotbar()
end
end)
for i, child in plr.Backpack:GetChildren() do
if not table.find(tools, child) then
table.clear(tools)
table.insert(tools, child)
for i, v in hotbar:GetChildren() do
if v:IsA("ViewportFrame") then
v:Destroy()
end
end
updateHotbar()
end
end
end)
game.ReplicatedStorage.Events.EquipToolRE.OnClientEvent:Connect(function()
for x, slot in pairs(hotbar:GetChildren()) do
if slot:IsA("Frame") then
local tool = tools[tonumber(slot.HotkeyNumber.Text)]
if tool.Parent ~= char then
slot.BackgroundColor3 = Color3.fromRGB(255, 255, 255)
slot.BackgroundTransparency = .5
slot:TweenSize(UDim2.new(.6,0,.25,0), "In", "Quad", .25)
else
slot.BackgroundColor3 = Color3.fromRGB(255, 255, 255)
slot.BackgroundTransparency = .25
slot:TweenSize(UDim2.new(.924,0,.127,0), "In", "Quad", .25)
end
end
end
end)
Server script
game.ReplicatedStorage.Events.EquipToolRE.OnServerEvent:Connect(function(plr, tool, parent)
local char = plr.Character
if char then
if parent ~= char then
char.Humanoid:UnequipTools()
char.Humanoid:EquipTool(tool)
else
tool.Parent = plr.Backpack
end
game.ReplicatedStorage.Events.EquipToolRE:FireClient(plr)
end
end)
All of my tools are stored into the StarterGear, it shows that I have the tool in my backpack but I can’t equip it from the hotbar…
Any help is appreciated, thanks.
