i want to make nodes for my phone map, but i literally don’t know anything on how to make it

i tried to normalize the part’s position to the map’s position but it doesn’t work

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")
local UIS = game:GetService("UserInputService")
local CAS = game:GetService("ContextActionService")
local RS = game:GetService("ReplicatedStorage")

local camera = workspace.CurrentCamera
local Phone = script.Parent.Parent.Parent.Parent
local Screen = Phone.Main.Screen
local delAppFrame = Screen.DeliveryApp
local delAppVPFrame = delAppFrame.ViewportFrame
local playerIndicatorTemplate = delAppFrame.Player
local deliveryIcon = Screen.DeliveryIcon
local exitButton = Screen.ExitButton
local openDeliveries = Screen.OpenDeliveries
local DeliveriesDB = delAppFrame.DeliveriesDB

local open = false

local waypoint = workspace:WaitForChild("Waypoint")

-- Remove the template from the frame
playerIndicatorTemplate.Parent = nil

-- Minimap variables
local offset, chunkSize, chunkHalfSize, currentX, currentZ
local scrollSpeed = 500
local playerIndicators = {}

-- Minimap Camera
local viewportCamera = Instance.new("Camera")
viewportCamera.FieldOfView = 20
delAppVPFrame.CurrentCamera = viewportCamera

-- Clone the map into the viewport frame
for _, descendant in ipairs(workspace.Map:GetDescendants()) do
	if descendant:IsA("BasePart") then
		descendant:Clone().Parent = delAppVPFrame
	end
end

-- Update minimap position and viewport camera
local function UpdateMinimap()
	local focusX = camera.Focus.Position.X / chunkSize
	local focusZ = camera.Focus.Position.Z / chunkSize
	local chunkX, chunkZ = math.floor(focusX), math.floor(focusZ)
	local x, z = focusX % 1, focusZ % 1

	if currentX ~= chunkX or currentZ ~= chunkZ then
		currentX, currentZ = chunkX, chunkZ
		local position = Vector3.new(chunkX * chunkSize + chunkHalfSize, 0, chunkZ * chunkSize + chunkHalfSize)
		viewportCamera.CFrame = CFrame.lookAt(position + offset, position, -Vector3.zAxis)
	end

	delAppVPFrame.Position = UDim2.new(1 - x, 0, 1 - z, 0)
end

-- Update player positions on the minimap
local function UpdatePlayers()
	local focusX = camera.Focus.Position.X / chunkSize
	local focusZ = camera.Focus.Position.Z / chunkSize

	for player, gui in pairs(playerIndicators) do
		if player.Character and player.Character:FindFirstChild("HumanoidRootPart") then
			local cFrame = player.Character:GetPivot()
			local x, z = cFrame.Position.X / chunkSize, cFrame.Position.Z / chunkSize
			gui.Position = UDim2.new(0.5 - focusX + x, 0, 0.5 - focusZ + z, 0)
			gui.Rotation = -player.Character.HumanoidRootPart.Orientation.Y
		end
	end
end

--[[ NOT IMPORTANT
-- Player joins: Add to minimap
local function PlayerAdded(player)
	local gui = playerIndicatorTemplate:Clone()
	gui.PlayerName.Text = player.Name
	gui.Parent = delAppFrame
	playerIndicators[player] = gui
end

-- Player leaves: Remove from minimap
local function PlayerRemoving(player)
	if playerIndicators[player] then
		playerIndicators[player]:Destroy()
		playerIndicators[player] = nil
	end
end


-- Set minimap zoom level
local function SetMinimapZoom(value)
	offset = Vector3.new(0, value, 0)
	chunkSize = offset.Y * math.tan(math.rad(viewportCamera.FieldOfView) / 2)
	chunkHalfSize = chunkSize / 2
	currentX, currentZ = math.huge, math.huge
	UpdateMinimap()
end

RunService.RenderStepped:Connect(function()
	UpdatePlayers()
end)

SetMinimapZoom(500)

camera:GetPropertyChangedSignal("Focus"):Connect(UpdateMinimap)

--normalizing
local UIPos = Vector2.new(waypoint.Position.X/chunkSize, waypoint.Position.Z/chunkSize)

--what i tried
local frame = Instance.new("Frame")
frame.Parent = delAppVPFrame
frame.Size = UDim2.new(0.1, 0, 0.1, 0)
frame.BackgroundColor3 = Color3.new(1, 1, 1)

	exitButton.Visible = false
	openDeliveries.Visible = false
end)

openDeliveries.MouseButton1Click:Connect(function()
	DeliveriesDB.Visible = not open
	open = not open
end)

-- Scroll zoom functionality

-- Disable scrolling when inside the app

	return Screen:IsAncestorOf(delAppFrame) and Enum.ContextActionResult.Sink or Enum.ContextActionResult.Pass
end, false, Enum.UserInputType.MouseWheel)

-- Connect player events

Players.PlayerRemoving:Connect(PlayerRemoving)

so please help! thanks in advance

Just get the direction from the player to the part in 3D, remove the Y axis and then the position of the waypoint on the map is the direction times some arbitrary constant number which represents the scale of the map.

#3

could you give me an example?. i don’t really understand (sorry)

#4

The code would look something like this

local pixelsPerStud = 5 -- How many pixels on the map correspond to one stud in the world

local direction = partPos - playerPos -- Get the direction from the player to the part in 3D space
local direction2D = Vector2.new(direction.X, direction.Z) -- Get rid of the Y axis of the 3D direction

local posOnMap = playerPosOnMap + direction2D * pixelsPerStud -- Find the position on the map (in pixels) where the waypoint should be

I haven’t tested this code, but something like that should work. I would advise you to really try to understand what code does & how it works instead of just blindly copy-pasting it tho.

for the pixel per stud, i found that my map is 2048x2048 (x and z) and my viewportframe (map), is 580x1050, (i multiplied its size because its in scale with the parent’s size offset). Should i use the pixel per stud for the x or for the z? or both?

#6

Both. As seen in my code, I do the multiplication on the entire Vector2, which already multiplies both.

#7

no, i meant that for the pixel per stud, should i use the ratio of the maps size divided by the frame’s x or the frame’s y offset?

#8

If it displays the entire map, then yes, you just do that division to get the ratio. If it displays a certain area of the map, then you’d multiply the ratio of the entire map by the zoom.

#9

no, what im asking is that to get the ratio of the entire map. should i do, the maps size divided by the frame’s x offset or the map size divided by the frame’s y offset?

If the longer axis (y) shows the entire map’s length, aka the bottom of the minimap is one edge of the map & the top is another edge of the actual map, then you divide the map’s size by the y offset.

However, if that isn’t the case, then neither. I’m supposing that the minimap doesn’t show the entire map at once on either axis.
If you know how many studs you are showing on the minimap on either axis at any time, then just divide that amount by the amount of pixels on that axis.
If you don’t know that, then I’m assuming that the minimap is zoomed in by some amount.
In that case, divide the entire map’s side length by the side that you zoom with (so if at no zoom the x axis fills the entire map, then you divide by that, otherwise if the y axis fills the entire map, you divide by that) and then multiply or divide by the zoom, depending on how zoom is defined, to get the ratio

If this still doesn’t answer your question, then please explain your case further, because as you can see, I’m making a lot of assumptions.

very sorry for the late reply, i totally forgot about this post, and thanks i tried dividing by the x offset and by the zoom and it basically works now thanks.
