Hello Everyone,
I’m trying to make a gun game with a little help with Alvin Blox’s sword fighting game series, I’m making the shop where you can buy a item and equip it, but it keeps saying the error above, any fixes will be great.
Script for serverhandle (I haven’t finished the whole series, but this part of the script does not work)
game.ReplicatedStorage:WaitForChild(“GetTools”).OnServerInvoke = function(player)
local items = {}
for _, object in pairs(game.ServerStorage:WaitForChild("Items"):GetChildren()) do
local itemProperties = {object.Name,object.Price.Value}
table.insert(items,itemProperties)
end
return items
end
game.ReplicatedStorage:WaitForChild(“ItemCheck”).OnServerInvoke = function(player,itemName)
if game.ServerStorage.PlayerData:FindFirstChild(player.Name).Inventory:FindFirstChild(itemName) then
return true
else
return false
end
end
game.ReplicatedStorage:WaitForChild(“PurchaseItem”).OnServerInvoke = function(player,itemName)
local Credits = player.leaderstats.Credits
local item = game.ServerStorage.Items:FindFirstChild(itemName)
if item then
--Item exists
if game.ServerStorage.PlayerData[player.Name].Inventory:FindFirstChild(itemName) then
if game.ServerStorage.PlayerData[player.Name].Equipped.Value == itemName then
-- Currency Unequipped
game.ServerStorage.PlayerData[player.Name].Equipped.Value = itemName
return "Equipped"
else
game.ServerStorage.PlayerData[player.Name].Equipped.Value = ""
return "Unequipped"
end
end
if Credits.Value >= item.Price.Value then
Credits.Value = Credits.Value - item.Price.Value
local itemValue = Instance.new("ObjectValue")
itemValue.Name = itemName
itemValue.Parent = game.ServerStorage.PlayerData[player.Name].Inventory
return true
else
return "NotEnoughCredits"
end
else
return "NoItem"
end
end
