Help with GetTouchingParts

Help and Feedback Scripting Support

So I am making an archer that shoots arrows but one thing that doesn’t really work is GetTouchingParts.
It doesn’t detect the touched even though the projectile got touched.

local function GetTouchingParts(part)
	if part ~= nil then
		local connection = part.Touched:Connect(function() end)
		local results = part:GetTouchingParts() -- not really working
		for i,v in pairs(results) do
			connection:Disconnect()
			return v
		end
	end
end

Remote.Event:Connect(function(firePoint)
	castParams.FilterDescendantsInstances = {character, HeroAbilitiesFolder}

	local projectile = Arrow:Clone()
	projectile:PivotTo(CFrame.new(x0))
	projectile.Parent = HeroAbilitiesFolder
	
	local nt = 0
	
	RunService.Heartbeat:Connect(function(stepped)
		nt += stepped
		-- fire arrow
		
		local results = GetTouchingParts(projectile.PrimaryPart)
		if results then
			hitDetection(results, projectile)
		end
	end)
end)

You need to move this connection outside the function

This?

local function GetTouchingParts(part)
	if part ~= nil then
		local results = part:GetTouchingParts()
		for i,v in pairs(results) do
			return v
		end
	end
end

RemotesFolder.FireProjectile.Event:Connect(function(firePoint, hitPosition)
	castParams.FilterDescendantsInstances = {character, HeroAbilitiesFolder}

	local projectile = ToolData.Projectile:Clone()
	projectile:PivotTo(CFrame.new(x0))
	projectile.Parent = HeroAbilitiesFolder
	
	local nt = 0
	
	coroutine.wrap(function()
		local connection = RunService.Heartbeat:Connect(function(stepped)
			nt += stepped
			if projectile.PrimaryPart ~= nil then
				local touchedConnection = projectile.PrimaryPart.Touched:Connect(function() end)
				local results = GetTouchingParts(projectile.PrimaryPart)
				if results then
					hitDetection(results, projectile)
					touchedConnection:Disconnect()
				end
			end
		end)

		table.insert(connections, connection)
	end)()
	
	Derbis:AddItem(projectile, ToolData.ProjectileDuration)
end)

Yes and you also need the connection outside the function. Try this…
"
local function GetTouchingParts(part)
if part ~= nil then
local results = part:GetTouchingParts()
for i,v in pairs(results) do
return v
end
end
end

RemotesFolder.FireProjectile.Event:Connect(function(firePoint, hitPosition)
castParams.FilterDescendantsInstances = {character, HeroAbilitiesFolder}

local projectile = ToolData.Projectile:Clone()
projectile:PivotTo(CFrame.new(x0))
projectile.Parent = HeroAbilitiesFolder

local nt = 0

coroutine.wrap(function()
	local connection = RunService.Heartbeat:Connect(function(stepped)
		nt += stepped
		if projectile.PrimaryPart ~= nil then
			local touchedConnection = projectile.PrimaryPart.Touched:Connect(function() end)
			local results = GetTouchingParts(projectile.PrimaryPart)
			if results then
				hitDetection(results, projectile)
				touchedConnection:Disconnect()
			end
		end
	end)

	table.insert(connections, connection)
end)()

Derbis:AddItem(projectile, ToolData.ProjectileDuration)

end)

local connection = part.Touched:Connect(function() end)

not sure why it’s breaking up my code, but just add this at the end of your script…

local connection = part.Touched:Connect(function() end)

To expand, yes you need the Touched connection for GetTouchingParts to work, but the connection must be established before touches occur. It is best to create the connection at the start of the projectile’s lifetime like so, and it will be cleaned up when the projectile is destroyed.

local projectile = Arrow:Clone()
projectile:PivotTo(CFrame.new(x0))
local connection = projectile.PrimaryPart.Touched:Connect(function() end)
projectile.Parent = HeroAbilitiesFolder

But why aren’t you using the Touched connection directly? It looks like your code is inefficiently re-creating the Touched signal. This edit using the connection directly should work the same if not better and removes a stuttering while loop

Remote.Event:Connect(function(firePoint)
	castParams.FilterDescendantsInstances = {character, HeroAbilitiesFolder}

	local projectile = Arrow:Clone()
	projectile:PivotTo(CFrame.new(x0))
	projectile.PrimaryPart.Touched:Connect(function(other: BasePart)
		hitDetection({other}, projectile)
	end)
	projectile.Parent = HeroAbilitiesFolder
end)
