pink

A Lua implementation of ink.

Ink is inkle's scripting language for writing interactive narrative, both for text-centric games as well as more graphical games that contain highly branching stories.

See WritingWithInk and RunningYourInk for the reference ink documentation.

Usage

To use it in your project download the latest source. You need just the pink directory.

Example

Given some .ink file like below, you can easily run it in your lua application using the pink library.

=== back_in_london ===
We arrived into London at 9.45pm exactly.
*   "There is not a moment to lose!"[] I declared. -> hurry_outside
*   "Monsieur, let us savour this moment!"[] I declared.
    My master clouted me firmly around the head and dragged me out of the door.
    -> dragged_outside

=== hurry_outside ===
We hurried home to Savile Row  -> as_fast_as_we_could

=== dragged_outside ===
He insisted that we hurried home to Savile Row
-> as_fast_as_we_could

=== as_fast_as_we_could ===
<> as fast as we could.

local pink = require('pink.pink')
-- 1) Load story
local story = pink('examples/game.ink')
while true do
  -- 2) Game content, line by line
  while story.canContinue do
    io.write(story.continue())
  end
  -- 3) Display story.currentChoices list, allow player to choose one
  if #story.currentChoices == 0 then break end -- cannot continue and there are no choices
  for i = 1, #story.currentChoices do
    print(i .. "> " .. story.currentChoices[i].text)
  end
  local answer=io.read()
  story.chooseChoiceIndex(answer)
end

See the examples directory for a simple text based example and a LÖVE integration.

This is how to run the text-based example:

$ lua examples/game.lua

or just:

$ examples/game.lua

And this example shows LÖVE integration:

$ love examples/love2d
