There's an error in my Pokemon game and it says "Can only use setPlayerIsUsing from backend"?

what does that mean?

Thanks in advance

par = true

script.Parent.Touched:connect(function(hit) if par == true then par = false for i,plr in ipairs(game.Players:GetPlayers()) do print(plr.Name) -- same result as printing hit.Parent.Name, but it will print everyones name coroutine.resume(coroutine.create(function() local char = plr.Character local chat = plr.PlayerGui.Chat1 local label = chat.Frame.TextLabel chat.Enabled = true char.Humanoid.WalkSpeed = 0 local text = "Mom: Son your late, Professor Oak is Waiting for you" for i = 1, #text do label.Text = string.sub(text, 1, i) wait() end wait(3) local text1 = "Ok Mom" for i = 1, #text1 do label.Text = string.sub(text1, 1, i) wait() end wait(3) local text2 = "Mom: Hurry your already an hour late" for i = 1, #text2 do label.Text = string.sub(text2, 1, i) wait() end wait(3) local text3 = "Ok I guess i got to go Now!" for i = 1, #text3 do label.Text = string.sub(text3, 1, i) wait() end wait(3) local text4 = "Mom: you better" for i = 1, #text4 do label.Text = string.sub(text4, 1, i) wait() end wait(3) chat.Enabled = false char.Humanoid.WalkSpeed = 20 end end) par = true -- your issue which kept it from replaying :D end)) end
