local Player = game:GetService("Players") local human = 'Workspace:WaitForChild("Humanoid")' Player.PlayerAdded:Connect(function(player) player.Name.human.JumpPower = 100 end)
game.Players.PlayerAdded:Connect(function(Player) Player.CharacterAdded:Connect(function(Character) Character.Humanoid.UseJumpPower = true Character.Humanoid.JumpPower = 300 end) end)
Your code has some serious problems. First of all, humanoid is not in workspace. It is in a model. player.Name is also referencing the player name. Not the character. If you wanted to do this you would have to put this in:
local Player = game:GetService("Players") Player.PlayerAdded:Connect(function(player) player.Character.Humanoid.JumpPower = 100 end)
I'm not sure if there is a limit on jump power but I am pretty sure that you can set it above 100.
