Help With Touched Event

Help and Feedback Scripting Support
#1

For some reason, my touch function keeps being fired when touching the ball, even though I’m not using the key bind. This only happens after I click the key bind once. Basically I only want the function to fire when the player presses a keybind.

This is what my scripts look like.

Keybind script

local Player = game.Players.LocalPlayer
local uis = game:GetService("UserInputService")
local rp = game:GetService("ReplicatedStorage")
local Set = game:GetService("ReplicatedStorage").Events.Set

uis.InputBegan:Connect(function(input)

	if input.KeyCode == Enum.KeyCode.F then
		Set:FireServer()
	end	

end)

Touch function

local rp = game:GetService("ReplicatedStorage")
local Set = rp:WaitForChild("Events").Set

Set.OnServerEvent:Connect(function(player) 
	local char = player.Character
	local root = char.HumanoidRootPart
	local function hit(part)
		if part.Name == "volleyball" then
			print("test")
			local ball = part 
			local Velocity = Instance.new("BodyVelocity")
			local Force = 50 
			local Direction = root.CFrame.LookVector

			ball.CFrame = char.Head.CFrame

			Velocity.Parent = ball
			Velocity.MaxForce = Vector3.new(1, 1, 1) * math.huge
			Velocity.Velocity = (Direction.Unit * Force/3) + Vector3.new(0, Force , 0)

			game:GetService("Debris"):AddItem(Velocity, 0.2)
			
		end
	end
	if player.Backpack.Ready.value == true then
			root.Touched:Connect(hit) 
	end
end)

Your Touched function is never disconnected, read more about connections and disconnections here and use it to implement it when you want the event to be disconnected.

In fact, you can use a GetTouchingParts() it works same with the touch but you can call it every time and it is not a loop

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local root = character:WaitForChild("HumanoidRootPart")
local uis = game:GetService("UserInputService")
local rs = game:GetService("ReplicatedStorage")
local set = rs:WaitForChild("Events"):WaitForChild("Set")

root.Touched:Connect(function(hit)
	if not player.Backpack.Ready.Value then
		return
	end
	local keysDown = uis:GetKeysPressed()
	for _, key in ipairs(keysDown) do
		if key.KeyCode == Enum.KeyCode.F then
			if hit.Name == "volleyball" then
				set:FireServer(hit)
			end
		end
	end
end)

local rp = game:GetService("ReplicatedStorage")
local set = rs:WaitForChild("Events"):WaitForChild("Set")

set.OnServerEvent:Connect(function(plr, part) 
	local bv = Instance.new("BodyVelocity")
	bv.Parent = part
	local direction = plr.Character.HumanoidRootPart.CFrame.LookVector
	part.CFrame = plr.Character.Head.CFrame
	bv.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
	bv.Velocity = (direction.Unit * 50/3) + Vector3.new(0, 50, 0)
	game:GetService("Debris"):AddItem(bv, 0.2)
end)
