jump script every 5 seconds? (R15)

--THIS LOOPS THE JUMP HOW DO I MAKE IT JUMP ONCE EVERY 5 SECONDS?

AFK_ON.MouseButton1Down:connect(function() 
	AFK_OFF.Visible = false
	AFK_ON.Visible = true
	while true do
		wait(5)
		local plr = game.Players.LocalPlayer
		local chr = plr.Character
		chr:WaitForChild("Humanoid"):connect(function()
		chr.Humanoid.Jump = true
		end)
	end
end)

--I TRIED THIS ALSO AND IT DOESN'T WORK

AFK_ON.MouseButton1Down:connect(function() 
	AFK_OFF.Visible = false
	AFK_ON.Visible = true
	while true do
		wait(5)
game.Players.LocalPlayer.Humanoid.Jump = true
	end
end)

So, I'm assuming this is a local script...

So, here is the code, hopefully fixed:

["AFK_ON"].MouseButton1Down:connect(function()
	["AFK_ON"].Visible = false
	["AFK_ON"].Visible = true	
	while wait(5) do --set that number to the amount of seconds to wait
	game.Players.LocalPlayer.Character.Humanoid.Jump = true
	end
end)

Your problem was that you were addressing the player, not the character.

game.Players.LocalPlayer.Humanoid.Jump = true

To address the character, you need to do this:

game.Players.LocalPlayer.Character.Humanoid.Jump = true

Notice the "Character" after the "LocalPlayer"

If this helped, please accept the answer. Thanks!
