An easy way to manage screen objects.

Okay I decided to here this time instead(didn't want to clutter your shout box with my problems.
Here is the Screen_output proc now:
Screen_output(txt, /Font/font)
            var/Text = font.wrap_text(txt, width_limit+2)
            var/list/words = list()
            var/word = ""
            var/output = ""
            for(var/i = 1 to length(Text))
                var/c = copytext(Text, i, i + 1)

                if(c == " ")
                    words += word
                    word = ""
                else
                    word += c
            if(word)
                words += word
                
            for(var/W = 1 to words.len)
                var/text = "[words[W]]"
                world << "[words[W]]"
                if(findtext(text, "\n"))
                    add_line(output)
                    output = ""
                else
                    output += text
                    output += " "
                
                if(W == words.len)
                    add_line(output)

Any ideas? I still get the problem where if a word takes up too much of the line it simply doesn't show the line.

I'm not sure where the problem is, but here's how I'd do it:

ChatLog
    proc
        add_message(txt)
            
            // insert line breaks into the string
            txt = font.wrap_text(txt, 184)
            
            // split the string into a list of strings
            var/list/lines = list()
            
            var/start = 1
            var/pos = findtext(txt, "\n")

            while(pos > 0)
                lines += copytext(txt, start, pos)
                start = pos + 1
                pos = findtext(txt, "\n", start)

            lines += copytext(txt, start)
            
            // display each line
            for(var/l in lines)
                add_line(l)

Works perfectly thank you so much.

Hey you wouldn't be able to show me how to make it so the first line is at the top and the last at the bottom would you? I've tried everything and nothing works.

In response to GreatFisher (#3)
Change the add_line proc to this:

        add_line(txt)

            // trim the text so it fits inside the chat log
            txt = font.cut_word(txt, 184)

            // I'm not sure why this is necessary, but it is. without it,
            // when you use the Say verb you'll see the top line of the
            // chat log change its text, then get moved to the bottom.
            spawn()
                // we loop through all lines because we need to reposition them all
                for(var/i = 1 to lines.len)
                    var/HudObject/h = lines[i]

                    // move the screen object up 16 pixels
                    var/py = h.sy - 16

                    // if it's sbove the top, wrap it around to the bottom
                    if(py < 0)
                        py = lines.len * 16 - 16

                    // update its position
                    h.pos(0, py)

                    // if its the next line, update its text too
                    if(i == next_line)
                        h.set_text(txt)

                // keep track of which line will be used next
                next_line -= 1
                if(next_line < 1)
                    next_line = lines.len

And change the line in the New() proc to this (add the " + 16"):

var/py = (line_count - i) * 16 + 16

If you display the lines in the opposite order you may need to call add_line in the opposite order (for multi-line messages).

yeah I got it to work thanks for all the help.
