Is there a way to have moving particle follow your mouse?

I need help creating a script to put into a sword that whenever I press "Z" it will create red particles where my mouse is, and follow my mouse- I would also like for the particles to do damage. Particles need to be able to disappear upon me press Z again.

Any ideas? I'm not sure how to do any of this, so can someone direct me to a source of information I can use to help?

Or can someone help me figure out the basis so I can stem off of it?

I won't do this for you, but I'll shoot you some ideas about going about this.

####- Suggestion 1, ####

Use a Local Script inserted into some Service that gets replicated to the player, like StarterGui.

####- Suggestion 2, ####

Now that we're using a Local Script, we can get the Local Player and the player's mouse. We would do this like so,

-- Local Script In StarterGui
local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

Get's player, and player's mouse

####- Suggestion 3, ####

Use user input service to detect the Z button being pressed.

####- Suggestion 4, #####

Insert an invisible part that follows the mouse, and place the particles in the part.

####- Suggestion 5, ####

Use mouse.Hit to get the CFrame of the mouse's world CFrame. This is very important. You would do the following to make a part where the mouse is in the world,

-- Local Script In StarterGui
local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()

local p = Instance.new("Part", game.Workspace)
p.CFrame = mouse.Hit

But this wouldn't really work if mouse.Hit is nil, and also because this isn't on a loop or event.

So Also,

Use a Mouse move event. Similar to so,

-- Local Script In StarterGui
local plr = game.Players.LocalPlayer
local mouse = plr:GetMouse()
mouse.Move:connect(function()
	if mouse.Hit ~= nil then
		local p = Instance.new("Part", game.Workspace)
		p.CFrame = mouse.Hit
	end
end)

Those are some of my ideas. I would provide an complete answer if I had more time. Later, if you're still having trouble, I could provide a better answer.

Good Luck!
