When I hold and drag my mouse around, it makes a gui box and every single model inside the gui box is selected ( kind of like Selected = true ).
The problem is, how do I make this gui box thingy select the models? Is there a special function like “IsOverlappingGui” ?? Thanks
I will only give you the concept of it since I’m busy at the time (might come back to give a script).
What you can do is store the mouse.Hit in a variable when the user begins dragging (UserInputService.InputBegan) and when they release their mouse (UserInputService.InputEnded) you store the mouse.Hit in another variable and then use the first and second mouse.Hit to create a Region3 (make sure you use the minimum of both positions as the min parameter and the maximum of both positions as the max parameter) and don’t forget to make an arbitrary Y position in both Vector3 or you could also calculate the Y position based on the camera’s distance from the mouse.Hit points. Lastly, you can use the “workspace:GetPartBoundsInBox()” function to determine the parts in the gui!
Yes . What you say works well , here an example of first part of your solution. (its in a local script,I used it to rotate a dummy with mouse, and this code just gets X axis diffrence)
local Players = game:GetService("Players")
local Player = Players.LocalPlayer
local Character = workspace.Dummy
local Mouse = Player:GetMouse()
function OnButton1Down()
local Event
local EndDrag = false
if not Mouse.Target then return end
local Dummy = Mouse.Target:FindFirstAncestor("Dummy")
if Dummy then
Event = Mouse.Button1Up:Connect(function()
EndDrag = true
Event:Disconnect()
end)
while not EndDrag
do
local StartValue = Mouse.X
wait(0.01)
local EndValue = Mouse.X
local Difference = -(StartValue - EndValue)
Character.PrimaryPart.CFrame *= CFrame.Angles(0,math.rad(Difference),0)
end
end
end
Mouse.Button1Down:Connect(OnButton1Down)
if you want to do it in server , use remote events
What if I want it to start selecting the parts as the box expands instead of selecting all the parts after the mouse is released?
Maybe not an elegant solution but it works. It maps an array of instances if not given all descendants of workspace and checks if the worldToScreenPoint is between our selection bound.
Best performance is with and filterList and filterType “Whitelist” ofcourse

--- if FilterType is Blacklist check if the instance is a Descendant or not and skip if so

--- Gui
--- Create the selection frame on the gui
local function createSelectionFrame()
local frame = Instance.new("Frame")
frame.BorderColor3 = Color3.new(0.278431, 0.568627, 1)

return frame

--- Start the selection loop
local function startSelect()

warn("Should not get called if its allready running!")
return
end
local startX, startY = mouse.X, mouse.Y
selectionFrame = createSelectionFrame()
renderConn = RunService.Heartbeat:Connect(function()
local endX, endY = mouse.X, mouse.Y
selectionFrame.Size = UDim2.fromOffset(endX - startX, endY - startY)
selectionFrame.Position = UDim2.fromOffset(startX, startY)
end)
end
--- Stops the selection loop
local function stopSelect()

return
end

selectionFrame = nil
end
end
--- Input
ContextActionService:BindAction("CustomSelection", function(action: string, state: Enum.UserInputState)
if state == Enum.UserInputState.Begin then -- Check if input is down
startSelect() -- Start selection
elseif state == Enum.UserInputState.End then -- Check if input is up
-- usage: findPartsInGuiObject(GuiObject, {Instance}?, "Whitliste" | "Blacklist") -> {Instance}
--[[
use findPartsInGuiObject(selectionFrame, <<filterList>>, <<"Whitelist" | "Blacklist">>) here
]]--
stopSelect() -- Stop selection
end
end, false, Enum.UserInputType.MouseButton1) -- Bind to MouseButton1
If you want it to select while draging use the function inside a while task.wait or heartbeat loop.
local selectionSteppedConn
local whitelist = {}
ContextActionService:BindAction("CustomSelection", function(action: string, state: Enum.UserInputState)
if state == Enum.UserInputState.Begin then -- Check if input is down
startSelect() -- Start selection
local parts = {}
selectionSteppedConn = game:GetService("RunService").Heartbeat:Connect(function()
-- Clear hightlight from previous parts result
for _, part in ipairs(parts) do
part.SelectionBox.Visible = false
end
parts = findPartsInGuiObject(selectionFrame, whitelist, "Whitelist")
-- Hightlight new parts result
for _, part in ipairs(parts) do
part.SelectionBox.Visible = false
end
end)
elseif state == Enum.UserInputState.End then -- Check if input is up
if selectionSteppedConn then
selectionSteppedConn:Disconnect()
selectionSteppedConn = nil
end
stopSelect() -- Stop selection
end
end, false, Enum.UserInputType.MouseButton1) -- Bind to MouseButton1

Selection while dragging:
SelectionWhileDragExample.rbxl (81.0 KB)
For that you can have a boolean variable that keeps track of if the user’s mouse is currently down and then have a UserInputService.InputChanged event (check the the Input.UserInputType == Enum.UserInputType.MouseMovement). You can then convert the code that handles getting all the parts from the two mouse.Hit variable and then call the function each time in the InputChanged event
