script.Parent.Fire.OnServerEvent:Connect(function(player,mousePos)	
    	script.Parent.Handle.Sound:Play()
    	local raycastParams = RaycastParams.new()
    	raycastParams.FilterDescendantsInstances = {player.Character}
    	raycastParams.FilterType = Enum.RaycastFilterType.Blacklist

    	local raycastResult = workspace:Raycast(script.Parent.Handle.Position,(mousePos - script.Parent.Handle.Position)*200,raycastParams)
    	
    	
    	if raycastResult then
    		local hitpart = raycastResult.Instance
    		local model	= hitpart:FindFirstAncestorOfClass("Model")
    		
    		if model then
    			if model:FindFirstChild("Humanoid") then
    				model.Humanoid.Health -= 20
    				local part = Instance.new("Part")
    				part.Transparency = 1
    				part.CanCollide = false
    				part.Parent = model
    				local smoke = Instance.new("Smoke")
    				smoke.Color = Color3.new(0.588235, 0.0431373, 0.0431373)
    				smoke.Parent = part
    				part.Position = hitpart.Position
    				smoke.Opacity = 0.2
    			end
    		end
    	end

    end)

I have tried many methods from other posts and i cant seem to find out how. I am very confused.

This post will be helpful: How do you visualize a raycast as a part? - #5 by incapaz

Also, to get the distance between 2 objects you must do (eye - target)

You did the opposite:


local raycastResult = workspace:Raycast(script.Parent.Handle.Position,(mousePos - script.Parent.Handle.Position)*200,raycastParams)

mousePos is the target and the Handle’s position is the eye (where the raycast is coming from) so instead you should swap it to local raycastResult = workspace:Raycast(script.Parent.Handle.Position,(script.Parent.Handle.Position - mousePos)*200,raycastParams)

Now, to make a raycast visible you will need to crrate a part like so:


local Part = Instance.new("Part", game.Workspace)
Part.Name == "Part"
Part.Size = Vector3.new(4, 4, distance) -- changed the size of the part to the magnitude of the distance
Part.CFrame = CFrame.new(script.Parent.Handle.Position, distance) * CFrame.new(0, 0, -distance/2) -- makes so that the back of the part is where the origin supposed to be

if i swap raycast result to that newer raycast result you have it does not damage the player?

also what should i put here? image

found a solution similar to this thanks for your help though!

It should be able to damage the player but it depends on your code and your distance is supposed to be (script.Parent.Handle.Position - mousePos)*200
