BodyForce applied to object in the wrong direction?

Hi, I'm trying to make a script that throws a ball in the direction the player clicked. What I have so far is

Local Script:

01local player = game.Players.LocalPlayer
02local mouse = player:GetMouse()
03local mousepos = mouse.Hit.p
04local handle = script.Parent
05local tool = handle.Parent
06 
07local RS = game:GetService("ReplicatedStorage")
08local ThrowBallEvent = RS:WaitForChild("ThrowBall")
09 
10tool.Activated:connect(function()
11    ThrowBallEvent:FireServer(tool, mousepos)   
12    tool:Destroy()  
13end)

Server Script:

01local RS = game:GetService("ReplicatedStorage")
02local ThrowBallEvent = RS:WaitForChild("ThrowBall")
03 
04local function ThrowBall(player, tool, mousepos)
05 
06    local ball = tool:clone()
07    ball.Parent = game.Workspace
08 
09    local rootpart = player.Character:FindFirstChild("HumanoidRootPart")
10    local humanoid = player.Character:FindFirstChild("Humanoid")
11    local head = player.Character:FindFirstChild("Head")
12 
13    local newhandle = ball:WaitForChild("Handle")
14    newhandle.Position = head.Position + head.CFrame.lookVector * 4
15    newhandle.CanCollide = true
16 
17    local force = Instance.new("BodyForce", newhandle)
18    local targetpos = mousepos
19    local initialpos = rootpart.Position
20    local direction = (mousepos - initialpos).unit
21    force.Force = direction * 300
22 
23end
24 
25ThrowBallEvent.OnServerEvent:Connect(ThrowBall)

The ball is thrown, but the direction of the force is completely arbitrary. Sometimes the ball will take off to the left, sometimes it'll go behind me, and sometimes it'll go straight. Any idea on why it's acting like this and not just going where I click?

`1`	`local` `initialpos` `=` `rootpart.Position`

^ Here you basically told it to go in the direction of ur rootparts position

`1`	`mousepos - initialpos).unit`

^ Basically these Two lines make the whatever go from ur mouse pos subtracted by ur HumanoidRootParts Position instead u wanna use CFrame then convert that to Vector like so

`1`	`local` `initialpos` `=` `rootpart.CFrame.LookVector` `--LOOKVECTOR = INFRONT OF YOU`

Hope this helps I'm not too good with Vector3s and position so I apologize if any of it was wrong as you were using Position for shooting something so it's confusing me also there r multiple Vectors LookVector, UpVector and RightVector

Also again i'm not too good with Positioning but wouldn't ur Mouse - your humroot make it shoot from ur mouse to your humroot idk tho again your code confuses me lmao AizakkuZ 226 — 5y

Didn't work unfortunately... only ensured that the ball spawned in front of me but the force was still applied pretty randomly. jdmartine_z 15 — 5y
