Why is my drone not falling/going under 0?

Help and Feedback Scripting Support
#1

I’ve been working on my drone for quite awhile. @T0ny helped me and now the drone is going up but not down. The VectorForce is set to 0 yet the drone isn’t going down. And I also noticed that if I try to subtract the VectorForce and make the Y axis go under 0 it’s not working.

Module Script:

local Drone = {}
Drone_mt = {__index = Drone}

Drone.new = function(model, camera)
	local self = {}
	self.Speed = 20
	self.Model = model
	self.VectorForce = model.VectorForce
	self.Camera = camera
	self.Direction = Vector3.new(0,0,0)
	self.Rotation = 0

	return setmetatable(self, Drone_mt)
end
function Drone:Up(actionName, inputState, inputObject)
	if inputState == Enum.UserInputState.Begin then
		self.Direction = self.Direction + Vector3.new(0, 1, 0)
	else
		self.Direction = self.Direction - Vector3.new(0, 1, 0)
	end
end

function Drone:Down(actionName, inputState, inputObject)
	if inputState == Enum.UserInputState.Begin then
		self.Direction = self.Direction - Vector3.new(0, 1, 0)
	else
		self.Direction = self.Direction + Vector3.new(0, 1, 0)
	end
end

function Drone:Update(actionName, inputState, inputObject)
	if not self.VectorForce then return end
	
	local X, Y, Z = math.clamp(self.Direction.X, 0, 1), math.clamp(self.Direction.Y, 0, 1), math.clamp(self.Direction.Z, 0, 1)
	local Direction = Vector3.new(X, Y, Z)
	self.VectorForce.Force = Direction * (self.Model.Mass * self.Speed)
end

return Drone

Local Script:

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local ContextActionService = game:GetService("ContextActionService")

local Module = require(game.ReplicatedStorage.Drone)
local LocalPlayer = Players.LocalPlayer
local character = LocalPlayer.Character.HumanoidRootPart
local newDrone = Module.new(character)


local function handleUp(actionName, inputState, inputObject)
	newDrone:Up(actionName, inputState, inputObject)
end

local function handleDown(actionName, inputState, inputObject)
	newDrone:Down(actionName, inputState, inputObject)
end

ContextActionService:BindAction("Up", handleUp, true, Enum.KeyCode.E)
ContextActionService:BindAction("Down", handleDown, true, Enum.KeyCode.Q)

RunService.Stepped:Connect(function(step)
	newDrone:Update(step)
end)

The problem is the drone isn’t going down when the vector force is 0.

Thanks!

I would appreciate every reply, I am stuck with this.

#3

Have you tried using other types of body movers? By not going down, do you mean that it keeps going up?

#4

No, it’s literally getting stuck mid-air.

#5

Try printing out direction after every action, see if it keeps increasing and not decreasing. I feel like that using else on inputstate.began will not work because when the function goes off, it will always be began and not else? I never use contextactionservice, but does it fire twice? one when button down and once when up?

Well now I changed the script and here’s the result:

local Drone = {}

Drone_mt = {__index = Drone}

Drone.new = function(model, camera)

local self = {}

self.Speed = 20

self.Model = model

self.VectorForce = model.VectorForce

self.Camera = camera

self.Direction = Vector3.new(0,0,0)

self.Rotation = 0

return setmetatable(self, Drone_mt)

end

function Drone:Up(actionName, inputState, inputObject)

if inputState ~= Enum.UserInputState.Begin then return end

self.Direction = self.Direction + Vector3.new(0, 1, 0)

end

function Drone:Down(actionName, inputState, inputObject)

if inputState ~= Enum.UserInputState.Begin then return end

self.Direction = self.Direction - Vector3.new(0, 1, 0)

end

function Drone:Update(actionName, inputState, inputObject)

if not self.VectorForce then return end

local X, Y, Z = math.clamp(self.Direction.X, -1, 1), math.clamp(self.Direction.Y, -1, 1), math.clamp(self.Direction.Z, -1, 1)

local Direction = Vector3.new(X, Y, Z)

self.VectorForce.Force = Direction * (self.Model.Mass * self.Speed)

end

return Drone

Well apparently this fixed the problem but when the direction is like in 30 you need to press a lot of Q in order to make it go minus. How will I make that?

#8

You could check if Direction.Y >= 1 and if so then return and vice versa for the opposite direction.

#9

Does that mean the direction can’t pass 1?

#10

Yeah, it means that if the direction.Y is 1, then it wont add more to it.

#11

Well then it can’t go up too much, am I correct? And will I also reset it to 0 whenever it tries to pass 1 so the player can still go up?
