How do I do damage numbers and OnKey functions?

Asked 303 views1 answers

This is me reposting my other question in more detail!

Probably a big topic, but I was browsing around the internet for scripting lessons on making advanced swords and stuff, and all I saw was scripting for beginners and things like that. For example, in the game 'Black Magic', they have weapons with showing damage numbers, and hotkey actions. I'm looking for a tutorial on how to do those two things, but so far I've found nothing. Here are some example of scripts I think I can use for this situation, this first script-box shows creating a damage gui:

function billboard(pos,text,time,color)
	local pos=pos or Vector3.new(0,0,0)
	local text=text or "Hello World!"
	local time=time or 2
	local color=color or Color3.new(1,1,0)
	local pos=pos+Vector3.new(0,5,0)
	local ep=Instance.new("Part")
	ep.Name="Effect"
	ep.formFactor="Custom"
	ep.Size=Vector3.new(0,0,0)
	ep.TopSurface="Smooth"
	ep.BottomSurface="Smooth"
	ep.CFrame=CFrame.new(pos)
	ep.Anchored=true
	ep.CanCollide=false
	ep.Transparency=1
	local bb=Instance.new("BillboardGui")
	bb.Size=UDim2.new(3,0,3,0)
	bb.Adornee=ep
	local tl=Instance.new("TextLabel")
	tl.BackgroundTransparency=1
	tl.Size=UDim2.new(1,0,1,0)
	tl.Text=text
	tl.TextColor3=color
	tl.TextScaled=true
	tl.Font="ArialBold"
	tl.TextStrokeTransparency = 0

	tl.Parent=bb
	bb.Parent=ep
	debris:AddItem(ep,time+.1)
	ep.Parent=game.Workspace
	delay(0,function()
		local frames=time/rate
		for frame=1,frames do
			wait(rate)
			local percent=frame/frames
			ep.CFrame=CFrame.new(pos)+Vector3.new(0,5*percent,0)
			tl.TextTransparency=percent
		end
		ep:remove()
	end)
end

Im still not sure how to make OnKey functions yet, that would also be helpful! Other than just having regular attacks, mabey an action on pressing Q or E or something like that might work, here's what I think:

local Key = value.Key
		local Down = value.Down
		if Key == "q" and Down then

Is that the right one? Well, thank you for reading, if you have an answer then put it in the reply box below!

There are different ways to detect keyboard inputs, but the preferred method is through UserInputService.InputBegan:

game:GetService("UserInputService").InputBegan:connect(function(input)
	if input.UserInputType.Name=="Keyboard"then
		local key=input.KeyCode.Name
		if key=="q"then
			-- ...
		end
	end
end)

The old method is (if you are using a Tool) using Mouse.KeyDown which automatically ignores keypresses when the user is typing in a textbox/chatting, but it is a deprecated feature.

To detect textbox focus (chat) so you can ignore key commands when somebody is really just chatting, you can use TextBoxFocused and TextBoxFocusReleased:

local uis=game:GetService("UserInputService")

local chatting=false
uis.TextBoxFocused:connect(function()chatting=true end)
uis.TextBoxFocusReleased:connect(function()chatting=false end)

uis.InputBegan:connect(function(input)
	if input.UserInputType.Name=="Keyboard"then
		if chatting then return end
		local key=input.KeyCode.Name
		if key=="q"then
			-- ...
		end
	end
end)
