So if a textbox has multiline it automatically creates a new line because it went past the textbox size
For example
How could I turn that into
{
[1] = “Lorem ipsum dolor sit amet, consectetur adipiscing elit.”,
[2] = " Maecenas eget convallis velit. Vivamus porta pulvinar aliquet."
}
Or something like that
You could have a table to store the strings and a variable for the max characters per line. EX:
local maxchars = 60 — I’m going with 60 here, adjust according to situation
local mtable = {}
local message = — the chatted string here
local lines = string.len(message) / maxchars
for i = 0, (lines-1) do
table.insert(mtable, string.sub(message, (i * maxchars) + 1, maxchars * (i+1))
end
Basically, we’re getting the number of lines in the message typed. Then we’re adding the strech of string from the start of the line to the next to the table proportionate to the number of lines in the string. Please take note that I made this without testing as I can’t open studio yet, so expect bugs. Nevertheless, this is the framework for your query
But what if I don’t know the max characters
What if it’s a textbox somebody else made I wouldn’t know what the limits would be
Ah, then it gets complicated. What I did is manually count the number of characters the box can hold without jumping to the next line. I’m currently not aware of how to do this dynamically. I’ll experiment around and get back to you soon
Maybe you can split the string by spaces and then use TextService to get the text size and then check if it’s more than the AbsoluteSize of the textbox
I would code all this myself but it’s night time and I should probably go to bed soon
You can do that with TextService? That’s interesting, I’ll search it up
Did you get something that works yet?
local lines, fontProperties = {}, {
textbox.TextSize,
textbox.Font,
textbox.AbsoluteSize
}
local getTextSize = function(s)
return TextService:GetTextSize(s, unpack(fontProperties))
end
local nth, size, currentText = 0, textbox.TextBounds, ""
for i = 1, size.Y / textbox.TextSize do
print(i, nth)
nth += 1
for i = 1, #textbox.Text:sub(nth) do
local textSize = getTextSize(textbox.Text:sub(nth, nth + i))
if textSize.Y > textbox.TextSize then
local text = textbox.Text:sub(nth, nth + i - 1)
table.insert(lines, {text, textSize})
nth += i - 1
break
end
end
end
table.insert(lines, {textbox.Text:sub(nth), getTextSize(textbox.Text:sub(nth))})
Ok this kind of works but when you add a space to a long piece of text that has not been wrapped yet and then add more after that it will result in this
and Idk how to detect that I tried but it didn’t work
Hey can somebody pls help me thanks
Hey it’s been a day lol u got anything yet ?
I know it’s a bit weird, but it works:
-- parses newlines created by the Enter/Return key into "\n"
local function parse_newlines(str: string): string
return string.gsub(str, "\n", "\\n")
end
-- splits string by "\n"
local function split_newlines(str: string): {string}
return string.split(parse_newlines(str), "\\n")
end
print(split_newlines("Hello, World!\nMy name is:\nMy. Robot"))
print(split_newlines([[Hello, World!
My name is:
Mr. Robot]]))
No I mean like the lines of text that are created after typing too much
local lines, fontProperties = {}, {
textbox.TextSize,
textbox.Font,
textbox.AbsoluteSize
}
local getTextSize = function(s)
return TextService:GetTextSize(s, unpack(fontProperties))
end
local nth, size, currentText = 0, textbox.TextBounds, ""
local lineCount = size.Y / textbox.TextSize
local oneLine = (textbox.TextBounds.Y <= textbox.TextSize or lineCount == 1)
for i = 1, lineCount do
nth += 1
for x = #textbox.Text - nth, 1, -1 do
local text = textbox.Text:sub(nth, nth + x)
local textSize = getTextSize(textbox.Text:sub(nth, nth + x))
if textSize.Y <= textbox.TextSize then
print(nth, x, textbox.Text:sub(nth, nth + x))
text = text:gsub("%s+[^%s]*$", function(s)
if not oneLine then
print(s)
lines[i + 1] = {s, getTextSize(s)}
return "" --text:match(`(.*){s}`)
end
end)
print(text)
print(lines[i], i)
if lines[i] then
text = lines[i][1] .. text
textSize = getTextSize(text)
if textSize.Y > textbox.TextSize then
for i = 1, #text do
textSize = getTextSize(text:sub(1, i))
if textSize.Y > textbox.TextSize then
table.insert(lines, {text:sub(i), getTextSize(text:sub(i))})
text = text:sub(1, i)
break
end
end
end
--[[
lines[i] = {text, textSize}
else
lines[i] = {text, textSize}
]]
end
lines[i] = {text, textSize}
nth += x
break
end
end
end
if #lines ~= lineCount then
warn("Number of lines do not match with the actual line count! (something must have gone wrong)")
end
Ok I am almost done
Only bug is that if you put too much spaces in a line it will bug a lot
