How can I make a part appear after the player has been in the game for a certain amount of time?

Greetings developers!

I am trying to make a part appear when a player has been in the game for about 5-6 minutes. How could I do that?

If you want to make the part appear only to that specific player after certain amount of time, you have to be using RemoteEvents and the code should look like this:
( Add a new instance called RemoteEvents inside of ReplicatedStorage )

--script inside of serverscriptservice 
game:GetService("Players").PlayerAdded:Connect(function(Player)
      while true do
              if Character.HumanoidRootPart.Position.Magnitude > 0 then --(line number 1)
                     InGameTime += 1
              end
              if InGameTime == 300 or InGameTime == 360 then
                   game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent"):FireClient()
                   break
              end
              task.wait(1)
     end
end)

--localscript inside of StarterCharacterScripts or StarterPlayerScripts
game:GetService("ReplicatedStorage"):WaitForChild("RemoteEvent").OnClientEvent:Connect(function(Player)
     local Part = Instance.new("Part",workspace)
end)

If you want to make the part appear to all players, you can use the following code:

game:GetService("Players").PlayerAdded:Connect(function(Player)
      local InGameTime = 0
       Player.CharacterAdded:Connect(function(Character)
             while true do
                   if Character.HumanoidRootPart.Position.Magnitude > 0 then --(line number 2)
                      InGameTime += 1
                  end
                  if InGameTIme == 300 then
                      local Part = Instance.new("Part",workspace)
                  end
                  task.wait(1)
           end
     end)
end)

For line number 1 and line number , you can remove the if statement unless and until you just want the player to just be present in the game irrelevent to the context if he/she is afk or not

@dragnmer

local Part = Instance.new("Part",workspace)

I assume I can use my PartName here right?
( sorry for the clearly dumb question )

For a simpler approach to @dragnmer solution, you can simply wait for some amount and check to see if the player exists. If they do, spawn the part.

You can change the identifier’s name as per your desire and comfort. The instance’s name shouldnt be changed
