Task list

This script shows a simple list of open tasks or objectives on screen. Add it as a definition script. Tasks are added and removed with an Execute a script action part:

add_task("pick up paycheck")
remove_task("pick up paycheck")

Task names are case sensitive. The list uses the font example; change the name to one of your fonts. The font's size, color, border and shadow are used.

task_list = {} -- open tasks

function draw_tasks()
  if #task_list == 0 then return end
  graphics.font = Fonts["example"]
  -- x position, y position, opacity
  graphics.drawFont(table.concat(task_list, "\n"), 100, 100, 1)
end

-- -1 = below the scene, 0 = above the scene, 1 = above the interfaces
graphics.addDrawFunc("draw_tasks()", 1)

function add_task(str)
  for i = 1, #task_list do
    if task_list[i] == str then return end -- already in the list
  end
  table.insert(task_list, str)
end

function remove_task(str)
  for i = #task_list, 1, -1 do
    if task_list[i] == str then table.remove(task_list, i) end
  end
end

The draw functions are described in the Graphics and media API. Test whether the list survives saving and loading in your game; if not, store the tasks in values or conditions as well.
