I’m not sure if the script is technically live yet, but I found it earlier today and noticed that this code doesn’t work as intended:
local testLabel = Instance.new("TextLabel")
testLabel.Selectable = false
testLabel.TextWrapped = true
testLabel.Position = UDim2.new(1, 0, 1, 0)
testLabel.Parent = BubbleChatScreenGui
local TextSizeCache = {}
--[[ FUNCTIONS ]]
local function getStringTextBounds(text, font, textSize, sizeBounds)
sizeBounds = sizeBounds or false
if not TextSizeCache[text] then
TextSizeCache[text] = {}
end
if not TextSizeCache[text][font] then
TextSizeCache[text][font] = {}
end
if not TextSizeCache[text][font][sizeBounds] then
TextSizeCache[text][font][sizeBounds] = {}
end
if not TextSizeCache[text][font][sizeBounds][textSize] then
testLabel.Text = text
testLabel.Font = font
testLabel.TextSize = textSize
if sizeBounds then
testLabel.TextWrapped = true;
testLabel.Size = UDim2.new(0, sizeBounds.x, 0, sizeBounds.y)
else
testLabel.TextWrapped = false;
end
TextSizeCache[text][font][sizeBounds][textSize] = testLabel.TextBounds
end
return TextSizeCache[text][font][sizeBounds][textSize]
end‘sizeBounds’ is a unique Vector2, so the cache just fills up with new vector2’s every time someone chats.
local t = {}
local key1 = Vector2.new(1, 2)
local key2 = Vector2.new(1, 2)
t[key1] = true
print(t[key2])
print(t[key1])
> nil
> trueAn okay fix would be to either use sizeBounds.X instead, or have separate tables for x and y.
Here’s a solution using metatables:
local function newCache(getter)
return setmetatable({}, {
__index = function(self, k)
local v = getter(k)
self[k] = v
return v
end
})
end
local function newClearingCache(duration, getter)
local mt = {}
function mt:__index(k)
setmetatable(self, {__index = newCache(getter)})
spawn(function()
wait(duration)
setmetatable(self, mt) -- cleanup
end)
return self[k]
end
return setmetatable({}, mt)
end
local TextBoundsCache = newCache(function(font)
local label = Instance.new("TextLabel")
label.Selectable = false
label.TextWrapped = true
label.Font = font
return newClearingCache(20, function(height)
return newCache(function(width)
local size = UDim2.new(0, width, 0, 512)
return newCache(function(text)
label.TextSize = height
label.Size = size
label.Text = text
label.Parent = screenGui
local bounds = label.TextBounds
label.Parent = nil
label.Text = ""
return bounds
end)
end)
end)
end)
print(TextBoundsCache[Enum.Font.SourceSans][18][64]["Hello world!"])
