Applying an impulse to a part doesn't work

Help and Feedback Scripting Support
#1

Hello. I am trying to make a vending machine where it dispenses a tool, a conveyor brings it to an opening, and an impulse is applied to make it fall out. I have the impulse applied at the correct direction, but the tool just bounces everywhere, even after removing the parts around it. I can provide a video if needed. Thanks.

You can just increase its density using CustomPhysicalProperties or increase its mass.

#3

make sure to apply impulse after you have set the parent

local part = ...
part.Parent = workspace
part:ApplyImpulse(force) -- apply impulse after we set the parent

I probably should’ve provided the script.

for _, button in pairs(script.Parent:GetChildren()) do
	if button:IsA("BasePart") and button:FindFirstChild("ClickDetector") then
		button.ClickDetector.MouseClick:Connect(function(player)
			local gear = game.ReplicatedStorage.ExtraModels.VendingMachine:FindFirstChild(button.Name):Clone()
			gear.Parent = script.Parent.Spawned
			local val = Instance.new("NumberValue")
			val.Parent = gear
			val.Value = #script.Parent.Spawned:GetChildren()
			gear:WaitForChild("Handle").CFrame = script.Parent.SpawnPos.CFrame
			if #script.Parent.Spawned:GetChildren() >= 2 then
				local min = 10
				local minChild = nil
				for i, child in pairs(script.Parent.Spawned:GetChildren()) do
					if child:FindFirstChild("Value") then
						if child.Value.Value < min then
							min = child.Value.Value
							minChild = child
						end
					end
				end
				minChild:Destroy()
			end
		end)
	end
end


script.Parent.Model.ImpulsePart2.Touched:Connect(function(hit)
	print(hit:GetFullName())
	if hit.Name == "Handle" and not hit:FindFirstChild("_done") then
		local attachment = Instance.new("Attachment")
		attachment.Parent = hit
		local velocity = Instance.new("VectorForce")
		velocity.Parent = hit
		velocity.Attachment0 = attachment
		local done = Instance.new("BoolValue")
		done.Name = "_done"
		done.Parent = hit
		velocity.Force = Vector3.new(-10, 0, 0)
		wait(1)
		velocity.Parent = nil
	end
end)

Mass is read only, and increasing the density doesn’t do anything

Alright, I got it to work. It turns out that the conveyor moving it was too large for the tool. Thanks for your help

#7

Oh I thought the problem was that the part was bouncing too much because of its low mass. By increasing the mass I meant adding an inivisble part thats larger which will increase the mass.

#8

Oh, makes sense. I don’t want to do that because these are being used as tools and I don’t want to change the tool grip.
