How to table.sort with GetTextBoundsAsync

Help and Feedback Scripting Support
#1

When I try to textservice gettextboundsasync to compare width of string,
first few calls throws both
“attempt to yield across metamethod/C-call boundary”
and “cannot resume non-suspended coroutine”.
why?

function font:get(name)
    if registered[name] then
        local fontApi = {}

        function fontApi:apply(ui, weight, italic)
            weight = weight or Enum.FontWeight.Regular
            ui.FontFace = Font.new(registered[name], weight, italic and Enum.FontStyle.Italic or Enum.FontStyle.Normal)
        end

        function fontApi:width(text, size, rt, weight, italic)
            local getText = Instance.new("GetTextBoundsParams")
            getText.Text = text
            getText.Font = Font.new(registered[name], weight or Enum.FontWeight.Regular, italic and Enum.FontStyle.Italic or Enum.FontStyle.Normal)
            getText.Size = size
            getText.RichText = rt or false
            local result
            result = textService:GetTextBoundsAsync(getText)
            return result.X
        end

        return fontApi
    end
end

You would have to pre-calculate each item’s width prior to table.sorting it assuming you’re calling fontApi:width in your comparison function
