C.Fighter's Textbox Library v1

-- BOX TREE STRUCTURE
-- First, we must create what I'll call from now on a "box tree".
local boxtree = {
    [1] = { -- The first box in the tree. The textbox numbering always starts at 1, and the textbox will always initialize to 1.
        name = "Someone", -- The name of the speaker. Can be omitted.
        portrait = {"sonic", SPR2_WAIT, A, 8}, -- The "portrait". Basically, this shows who is speaking just above the textbox.
        -- Uses in-game sprites as a basis: skin, spr2, frame, angle. Can be omitted.
        color = SKINCOLOR_BLACK, -- The color to use for the portrait. Has to be supplied with the portrait.
        text = "Is anyone there?", -- The text to print into the box. Puts the "text" in "textbox".
        sound = sfx_talks, -- Optional. The sound to play for every letter printed.
        delay = 3*TICRATE, -- The time to wait for to automatically advance the textbox. Required for non-movement-locked textboxes, otherwise optional.
        mini = { -- Mini-text, similar to Deltarune. Yes.
            {portrait = {"sonic", A}, color = SKINCOLOR_BLUE, text = "WHO are you?", pos = "dl"}, -- Portrait (has to use the TBXM sprite, no angles), color, text, position.
            {portrait = {"tails", A}, color = SKINCOLOR_ORANGE, text = "Doesn't matter, Sonic!", pos = "dr"} -- You can have multiple.
        },
        script = function(player) -- This runs once the textbox is displayed. Can be used to lock the player out of activating the box again.
            -- Yeah you can put whatever code you want. Lol.
        end,
        next = 2 -- The ID of the next textbox. Set to 0 to close the textbox once the box is skipped.
    },

    [2] = {
        -- The same format applies to the other boxes.
    },
 
    -- CHOICES
    [3] = {
        -- You can have someone speaking with the choice if you want.
        choices = { -- This defines what you can choose.
            {text = "Um...", box = 4, pos = "left"}, -- The option itself, then the box ID it takes you to, then the relative position.
            {text = "Do I know you?", box = 5, pos = "right"} -- Try to position these so that scrolling L->R makes sense. Order does metter here.
        }
    },
 
    -- ...
}

-- FUNCTIONS
-- Now that you have the table ready, we can summon it by calling THIS function:
CFTextBoxes:DisplayBox(player, boxtree, move)
-- "player" determines the player it's shown for. If it's nil, the textbox is displayed globally.
-- "boxtree" is the box tree that the textbox will use. Of course.
-- "move" determines whether the player can move during the textbox. False or nil means movement lock, true means no movement lock.

-- If you want to close it prematurely: call
CFTextBoxes:CloseBox(player)

-- And for a premature push to the next box:
CFTextBoxes.Advance(player)
-- Note that this one has a dot instead of a colon. Remember that!
