I need a replacement for mouse.Hit.p ?

One that does not ignore targetfilter. Any help? (I'm a little amateur with working the mouse)

This is all the coding you need to know:

Wait();
local max_power=125;--the maximum amount of power that can be reached
local deb=false;--is the mouse being held or not?
local throwing=false;--is the ball being thrown or not?
local power=0;--the current power being used
local keys={};--table for keys being pressed

--associative array for background
local frame_ary={
	['BackgroundColor3']=Color3.new(50/255,50/255,50/255);
	['BackgroundTransparency']=0.1;
	['BorderColor3']=Color3.new(1,1,1);
	['Position']=UDim2.new(0.1,0,0.5,0);
	['Size']=UDim2.new(0.025,0,0.3,0);
};

--associative array for charge ball
local bar_ary={
	['BackgroundColor3']=Color3.new(50/255,1,50/255);
	['BorderSizePixel']=0;
};

--colors the bar the proper color
function color(bar)
	bar.BackgroundColor3=Color3.new(power/max_power,1-power/max_power,0);
end

--associative array for Instance type name
function doit(array,name)
	local a=Instance.new(name);
	for i,v in pairs(array) do
		if pcall(function() return a[i]; end) then
			a[i]=v;
	end end
	return a;
end

--throws the ball
function fire(v,power)
	local vCharacter = game.Players.LocalPlayer.Character;
	local vPlayer = game.Players.LocalPlayer;
	local thing = script.Parent:Clone();
	local missile = thing.Handle
	local spawnPos = vCharacter.PrimaryPart.Position	

	spawnPos  = spawnPos + (v * 10)
	targetPos = spawnPos + (v * power)

	missile.Position = spawnPos
	missile.Velocity = v * power
	missile.CanCollide = true
	missile.Elasticity = .05
	missile.Friction = .7
	missile.CFrame=CFrame.new(spawnPos,targetPos)*CFrame.Angles(math.rad(90),0,0);

	local bodyp = Instance.new("BodyVelocity")
	bodyp.maxForce = Vector3.new(1e3,1e3,1e3)
	bodyp.P = power*100;
	bodyp.velocity = (targetPos-missile.CFrame.p).unit*power
	bodyp.Parent = missile

	local new_script = script.Script:clone()
	new_script.Name=tostring(power);
	new_script.Disabled = false
	new_script.Parent = missile
	thing.Parent = game.Workspace

	game:GetService("Debris"):AddItem(script.Parent,0);
end

--if the handle is touched while in handoff position
script.Parent.Handle.Touched:connect(function(part)
	if keys['x'] and part.Parent:findFirstChild("Humanoid") then
		keys['x']=false;
		script.Parent.GripPos=Vector3.new(0.2,0.2,0.3);
		script.Parent.GripForward=Vector3.new(0.7688,0.4522,-0.4522);
		script.Parent.GripUp=     Vector3.new(-0.5687,0.8068,-0.16);
		script.Parent.GripRight=  Vector3.new(0.2925,0.3802,0.8774);
		script.Parent.Parent=part.Parent;
end end
);

--when the tool is equipped
script.Parent.Equipped:connect(function(mouse)
	mouse.Icon = "rbxasset://textures\\GunCursor.png";
--when clicked
	mouse.Button1Down:connect(function()
		power=0;
		throwing=true;
		deb=true;
		local sg=Instance.new("ScreenGui",game.Players.LocalPlayer.PlayerGui);
		local frame=doit(frame_ary,"Frame");
		frame.Parent=sg;
		local bar=doit(bar_ary,"Frame");
		bar.Parent=frame;
		while deb do
			power=power<max_power and power+8 or max_power;
			bar.Size=UDim2.new(1,0,power/max_power,0);
			bar.Position=UDim2.new(0,0,1-power/max_power,0);
			color(bar);
			Wait();
		end
		if throwing then
			game:GetService("Debris"):AddItem(sg,0);
			fire((mouse.Hit.p-game.Players.LocalPlayer.Character.Head.Position).unit,power);
			power=0;
	end end
	);
	
--when released
	mouse.Button1Up:connect(function()
		deb=false;
	end
	);

--when a key is pressed
	mouse.KeyDown:connect(function(key)
		keys[key]=true;
	--if handoff motion
		if key:lower()=="x" then
			while keys[key:lower()] do
			script.Parent.GripPos=Vector3.new(0,0.5,0);
			script.Parent.GripForward=Vector3.new(0,0,0);
			script.Parent.GripUp=     Vector3.new(0,0,0);
			script.Parent.GripRight=  Vector3.new(0,0,1);
				Wait();
			end
			script.Parent.GripPos=Vector3.new(0.2,0.2,0.3);
			script.Parent.GripForward=Vector3.new(0.7688,0.4522,-0.4522);

			script.Parent.GripRight=  Vector3.new(0.2925,0.3802,0.8774);
	end end
	);

--when a key is released
	mouse.KeyUp:connect(function(key)
		keys[key:lower()]=false;
	end
	);
end
);

You could create your own method instead of using mouse.Target, or mouse.Hit. ROBLOX allows you to create formats for that kind of stuff.
