Textbox help (pretty please)

Help and Feedback Scripting Support
#1

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!

I want to make a textbox navigable only with the cursor

  1. What is the issue? Include screenshots / videos if possible!

I cant include screenshots but I can include the code so far
l

ocal TextService = game:GetService("TextService")

local scrollingFrame = script.Parent;
local textBox = scrollingFrame:WaitForChild("TextBox");


local function getTextSize(text)
	return TextService:GetTextSize(text, textBox.TextSize, textBox.Font, textBox.AbsoluteSize)
end

local function getBoundsFromCursor()
	local cursor = math.max(textBox.CursorPosition, textBox.SelectionStart);
	if cursor == -1 then return end;
	local lines = textBox.Text:sub(0, cursor - 1):split("\n");
	local line = lines[#lines];
	local lineIndex = #lines;
	return Vector2.new(getTextSize(line).X, lineIndex * textBox.TextSize); 
end

local function isInWindow(bounds)
	local canvasPos = scrollingFrame.CanvasPosition;
	local windowSize = scrollingFrame.AbsoluteWindowSize
	return bounds.X >= canvasPos.X and bounds.X <= windowSize.X, bounds.Y >= canvasPos.Y and bounds.Y <= windowSize.Y
end

textBox:GetPropertyChangedSignal("TextBounds"):Connect(function() 
	scrollingFrame.CanvasSize = UDim2.fromOffset(textBox.TextBounds.X+1, textBox.TextBounds.Y+1)
end)

textBox:GetPropertyChangedSignal("CursorPosition"):Connect(function()
	if textBox:IsFocused() then
		local cursorBounds = (getBoundsFromCursor());
		local xInBounds, yInBounds = isInWindow(cursorBounds);
		scrollingFrame.CanvasPosition = cursorBounds - Vector2.new(0, textBox.TextSize);
	end
end)

scrollingFrame.CanvasSize = UDim2.fromOffset(textBox.TextBounds.X+1, textBox.TextBounds.Y+1)
  1. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
    Basically this script is inside a scrollingframe with a textbox embedded inside it, the text is on the top left corner.
    basically if I type to much to the point that the text goes off the screen, the canvasposition changes making the cursor and the text visible

local TextService = game:GetService("TextService")

local scrollingFrame = script.Parent;
local textBox = scrollingFrame:WaitForChild("TextBox");


local function getTextSize(text)
	return TextService:GetTextSize(text, textBox.TextSize, textBox.Font, textBox.AbsoluteSize)
end

local function getBoundsFromCursor()
	local cursor = math.max(textBox.CursorPosition, textBox.SelectionStart);
	if cursor == -1 then return end;
	local lines = textBox.Text:sub(0, cursor):split("\n");
	local line = lines[#lines];
	local lineIndex = #lines;
	return Vector2.new(getTextSize(line).X, lineIndex * textBox.TextSize); 
end

local function isInWindow(bounds)
	local canvasPos = scrollingFrame.CanvasPosition;
	local windowSize = scrollingFrame.AbsoluteWindowSize
	return bounds.X >= canvasPos.X and bounds.X <= windowSize.X, bounds.Y >= canvasPos.Y and bounds.Y <= windowSize.Y
end

local function formula(x, y)
	return math.floor(x / y) * y
end

local function update()
	if textBox:IsFocused() then
		local cursorBounds = (getBoundsFromCursor()) - Vector2.new(0, textBox.TextSize)
		local xInBounds, yInBounds = isInWindow(cursorBounds);
		scrollingFrame.CanvasPosition = Vector2.new(formula(cursorBounds.X, scrollingFrame.AbsoluteWindowSize.X), formula(cursorBounds.Y, scrollingFrame.AbsoluteWindowSize.Y));
	end
end

textBox:GetPropertyChangedSignal("TextBounds"):Connect(function() 
	scrollingFrame.CanvasSize = UDim2.fromOffset(textBox.TextBounds.X+1, textBox.TextBounds.Y+1)
end)

textBox:GetPropertyChangedSignal("CursorPosition"):Connect(update);
textBox:GetPropertyChangedSignal("Text"):Connect(update);

scrollingFrame.CanvasSize = UDim2.fromOffset(textBox.TextBounds.X+1, textBox.TextBounds.Y+1)

nvm i fixed it.
if anybody wants to steal this code, you can.
