Howdy, this is my first topic in the developer forum. If I put this in the wrong category please guide me to the right one.
-
What do you want to achieve? Keep it simple and clear!
I am making a 2.5D game and I want to make a part you can Grab and Throw, I want it to throw using UserInputService and go to the direction the player is facing
-
What is the issue? Include screenshots / videos if possible!
I have already made the grabbing system using WeldConstraint, but I’m stuck in the throwing system.
-
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
I have tried looking for solutions everywhere. But they don’t seem to work.
This is my localscript located inside StarterGUI:
local apple = workspace.parts["1-5"]:WaitForChild("Apple")
local prompt = apple.ProximityPrompt
local UIS = game:GetService("UserInputService")
local animation = script:WaitForChild("Animation")
local grabbing
prompt.Triggered:Connect(function(player)---- when they press the prompt they grab the part.
grabbing = true
local char = player.Character or player.CharacterAdded:Wait()
local hum = char:WaitForChild("Humanoid")
local AnimTrack = hum:LoadAnimation(animation)
local weld = Instance.new("WeldConstraint")
weld.Parent = char
weld.Part0 = apple
weld.Part1 = char.HumanoidRootPart
apple.Position = char.HumanoidRootPart.Position + Vector3.new(-2, 0, 0)
UIS.InputBegan:Connect(function(input, gpe)---- I want it so if they press the "F" key it throws the part in the direction the character is facing.
if gpe then end
if grabbing == true and input.KeyCode == Enum.KeyCode.F then
--------- What should I add here to throw the part forward?
grabbing = false
apple.Parent = workspace
weld:Destroy()
AnimTrack:Play()
wait(0.2)
AnimTrack:Stop()
end
end)
end)
Any help is appreciated.

Let’s try a little template:
Create a Tool inside Workspace, with a regular part being the handle. Then, create a script inside that tool, and the rest of the work will be done by me;
Also, make sure the CanBeDropped property is set to false, inside the tool.
local tool = script.Parent
local handle = tool.Handle
local throwing = false
local throwSpeed = 100
tool.Activated:Connect(function()
if throwing == true then return end
throwing = true
local player = game.Players:FindFirstChild(tool.Parent.Parent.Name) or game.Players:GetPlayerFromCharacter(tool.Parent)
local cframe = handle.CFrame
tool.Parent = workspace
handle.CFrame = cframe
handle:SetNetworkOwner(nil)
handle.BodyLinearVelocity = player.Character.HumanoidRootPart.CFrame.LookVector * throwSpeed
task.wait(0.5)
throwing = false
end)
Let me know if it works or not, and I’ll be happy to help.

I have created the tool and named a normal part “Handle” and put a server script inside the tool. I can pick it up fine, but I cannot throw it. It gives me this error

local cframe = handle.CFrame
Can you put a print(handle) before this line, because it’s apparently indexing nil.

Like this? I have tried it but it still gives the same error.

Does anything print from the script, though?
1 Like
yes, it does, but it prints “nil”

Can you replace line 2 in the script with this:
local handle = tool.Handle

It got rid of the error, but now there’s this error

My bad, it’s AssemblyLinearVelocity. Replace the line with this:
handle.AssemblyLinearVelocity = player.Character.HumanoidRootPart.CFrame.LookVector * throwSpeed

There are no more errors anymore, but I still can’t throw the part.

Does the part drop when you try throwing it?
1 Like
Nope, it does not drop I still hold it whenever I activate the tool.

Do you even know if the Parent property gets changed?
1 Like
The parent property gets changed when I pick it up, it’s parent becomes the character. But, when I activate it the parent doesn’t change, it’s still the character.

I have fixed it, I just had to move the “tool.Parent” above the “Local cframe”. But, another question is how do I make it throw the part when a key is pressed? Instead of LeftClicking the tool to activate it.
This would require a client script, alongside a remote event, if you want to detect a key press.
Also your fix just gave the script a millisecond more time to set the CFrame. You can just add a delay. Update your script to this:
local tool = script.Parent
local handle = tool.Handle
local throwing = false
local throwSpeed = 100
tool.Activated:Connect(function()
if throwing == true then return end
throwing = true
local player = game.Players:FindFirstChild(tool.Parent.Parent.Name) or game.Players:GetPlayerFromCharacter(tool.Parent)
local cframe = handle.CFrame
tool.Parent = workspace
task.wait()
handle.CFrame = cframe
handle:SetNetworkOwner(nil)
handle.BodyLinearVelocity = player.Character.HumanoidRootPart.CFrame.LookVector * throwSpeed
task.wait(0.5)
throwing = false
end)
How would I go about doing that? Sorry, I don’t know much about remote events.
Alright then, create a remote event inside the tool, don’t name it. Then create a local script inside the tool aswell.
The client script:
local UIS = game:GetService("UserInputService")
local tool = script.Parent
local handle = tool.Handle
local remote = tool.RemoteEvent
local keyCode = "E" --Change what key to press
UIS.InputBegan:Connect(function(input,gameProcessed)
if (not gameProcessed) or UIS:GetFocusedTextBox() then return end
if input.KeyCode == Enum.KeyCode[keyCode] then
remote:FireServer()
end
end)
…and the server:
local tool = script.Parent
local handle = tool.Handle
local remote = tool.RemoteEvent
local throwing = false
local throwSpeed = 100 --Change the throwing speed of the ball
remote.OnServerEvent:Connect(function(player)
if throwing == true then return end
throwing = true
local cframe = handle.CFrame
tool.Parent = workspace
handle.CFrame = cframe
handle:SetNetworkOwner(nil)
handle.BodyLinearVelocity = player.Character.HumanoidRootPart.CFrame.LookVector * throwSpeed
task.wait(0.5)
throwing = false
end)
See if any errors occur.

No errors, but it doesn’t work. The tool doesn’t get thrown.
