How to make string:match() not case sensitive?

[YouthfulPat501]

im making a script where if you say something like “lol” it plays a laughing animation and plays a laughing sound. im using string:match() for the chat message

the problem is if you write “haha” it will work but if you write “Haha” it wont
anyone know how to make it do so without needing to write ‘or msg:match(“Haha”)’?

string.lower() or string.upper() makes a string lowercase or upper case. This could help.

how should i use it?

canChat = true

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local hum = char:WaitForChild("Humanoid")
		plr.Chatted:Connect(function(msg)
			if canChat == true then
				msg:lower() --should i put it in here like this?
				if msg:match("hi") or msg:match("hello") then
					local walkspeed = hum.WalkSpeed
					local jumppower = hum.JumpPower
					hum.WalkSpeed = 0
					hum.JumpPower = 0
					local anim = hum:LoadAnimation(script.Wave)
					anim.Priority= Enum.AnimationPriority.Action
					anim.Looped = false
					
					canChat = false
					char.Humanoid.Hi:Play()
					anim:Play()
					wait(1.7)
					canChat = true
					hum.WalkSpeed = walkspeed
					hum.JumpPower = jumppower
					anim:Stop()
				elseif msg:match("bye") then
					local walkspeed = hum.WalkSpeed
					local jumppower = hum.JumpPower
					hum.WalkSpeed = 0
					hum.JumpPower = 0
					local anim = hum:LoadAnimation(script.Wave)
					anim.Priority= Enum.AnimationPriority.Action
					anim.Looped = false
					
					canChat = false
					char.Humanoid.Bye:Play()
					anim:Play()
					wait(1.7)
					canChat = true
					hum.WalkSpeed = walkspeed
					hum.JumpPower = jumppower
					anim:Stop()
				elseif msg:match("haha") or msg:match("hah") or msg:match("lol") or msg:match("xd") or msg:match("hehe") or msg:match("heh") then
					local walkspeed = hum.WalkSpeed
					local jumppower = hum.JumpPower
					hum.WalkSpeed = 0
					hum.JumpPower = 0
					local anim = hum:LoadAnimation(script.Laugh)
					anim.Priority= Enum.AnimationPriority.Action
					anim.Looped = false

					canChat = false
					char.Humanoid.Haha:Play()
					anim:Play()
					wait(5)
					canChat = true
					hum.WalkSpeed = walkspeed
					hum.JumpPower = jumppower
					anim:Stop()
				elseif msg:match("what") or msg:match("huh") or msg:match("?") then
					local walkspeed = hum.WalkSpeed
					local jumppower = hum.JumpPower
					hum.WalkSpeed = 0
					hum.JumpPower = 0
					local anim = hum:LoadAnimation(script.Confused)
					anim.Priority= Enum.AnimationPriority.Action
					anim.Looped = false

					canChat = false
					char.Humanoid.Huh:Play()
					anim:Play()
					wait(5)
					canChat = true
					hum.WalkSpeed = walkspeed
					hum.JumpPower = jumppower
					anim:Stop()
				elseif msg:match("yes") or msg:match("yeah") or msg:match("ye") then
					local walkspeed = hum.WalkSpeed
					local jumppower = hum.JumpPower
					hum.WalkSpeed = 0
					hum.JumpPower = 0
					local anim = hum:LoadAnimation(script.Agree)
					anim.Priority= Enum.AnimationPriority.Action
					anim.Looped = false

					canChat = false
					char.Humanoid.Yes:Play()
					anim:Play()
					wait(2)
					canChat = true
					hum.WalkSpeed = walkspeed
					hum.JumpPower = jumppower
					anim:Stop()
				end
			end
		end)
	end)
end)

heres my code. i tried putting msg:lower() before the if statements but it doesnt work

[FangScripting]

msg.match(string.lower("hit"))

Something like that.
Reference:

string.lower() function in Lua programming

[YouthfulPat501]

still nothing. doesnt even return an error.

[SpiritXmas1 (Soup)]

What you did is almost correct, just overwrite msg with the new lower cased msg.

It would look like the following

local msg = msg:lower() -- this would work
if msg:match("hi") or msg:match("hello") then
