-- player_tiles defines the default array of player tiles from which
-- RandomTiles chooses. New tiles entries can be added anywhere in this array,
-- and lines can be removed or comment out to disable a tile, but remember that
-- a comma must come after each entry. Each entry must have at minimum a `mons'
-- field defined with a name for the entry. The actual tile to use can come
-- from this `mons' field or either of the optional fields `tile' and
-- `tileset', which are described later. If neither `tile' nor `tileset' are
-- defined, then `mons' must be the monster name as seen under xv in-game (and
-- as defined in the source file mon-data.h). For example, the entry:
--
--     { mons = "hell sentinel" },
--
-- is equivalent to the rc option:
--
--     tile_player_tile = mons:hell sentinel
--
-- If the `mons' field isn't the monster's name, either because you've renamed
-- it or because the corresponding monster doesn't exist, set the `tile' field
-- to the tile's full name. The player_name_pairs[] array in the source file
-- rltiles/tiledef-player.cc defines these names for all player tiles, and only
-- tiles defined in this file can be used. These are the tiles you see in
-- crawl's tilesheet file player.png.
--
-- For example, the following entry:
--
--     { mons = "a Zot statue", tile = "mons_zot_statue" },
--
-- is equivalent to the rc option:
--
--     tile_player_tile = tile:mons_zot_statue
--
-- For monsters like butterflies that have variant tiles, you can set the field
-- `num_var' to the number of variants in order to use them. The array
-- _tile_player_count[] in rltiles/tiledef-player.cc defines how many variants
-- exist for each tile, but it's easier to look in the folders under
-- rltiles/mon where the individual tile images are and see how many variants a
-- tile has. Since rltiles/mon/animals has butterfly.png through
-- butterfly10.png, which means 11 variants, the entry is:
--
--     { mons = "butterfly", tile = "mons_butterfly", num_var=11 },
--
-- By default RandomTiles chooses a new variant with each UI action (i.e. any
-- keystroke that's not in a menu or prompt), even if the player's turn
-- didn't change. Set the field `var_type' to "fixed", "sequence", or
-- "oscillate" to change this behavior. With "fixed" a single variant is
-- chosen when the entry is chosen, and with "sequence" and "oscillate",
-- variants are progressed through in order (sequence) or forward-reverse
-- order (oscillate) with each UI action.
--
-- You can define a custom set of variants for use in an entry using the
-- `tileset' field. For example, here's an entry for the Serpent of Hell that
-- randomly chooses a Hell variant with every UI action:
--
--     { mons = "The Serpent of Hell",
--       tileset = { "mons_serpent_of_hell_tartarus",
--                   "mons_serpent_of_hell_cocytus",
--                   "mons_serpent_of_hell_dis",
--                   "mons_serpent_of_hell_gehenna" } },
--
-- Custom tilesets can use any of the `var_type' values described above.
--
-- When the `tileset' field is used, there are special `var_type' values of
-- "terrain", "status", "percent_hp", and "xl" available, which will change
-- the tile based on a condition. To use one of these, make the
-- tileset field into an an array of arrays, with the first entry in the
-- inner array giving the condition value and the second giving the
-- corresponding tile applied under that condition. The first entry in
-- `tileset' must have an inner array value of "default" for when no other
-- entry matches.
--
-- For numeric `var_type' values like "percent_hp" and "xl", the first
-- condition value for each non-default entries must be a number, and the
-- tile of an entry is used if the player's current value is in less than or
-- equal to the entry's condition value and greater than any other
-- non-default entry in the tileset. For string values like "terrain" and
-- "status", the first condition value will be a string that is matched
-- against the player's current value. For "status", multiple status values
-- can be active for the player, so we always use the first matching entry,
-- and they should be listed in tileset in order of preference.
--
-- See the entry for Ilsiuw to see a var_type example of "terrain", and the
-- entry for Bai Suzhen to see an example of "percent_hp". Here is an
-- example entry using a var_type of "status" that will use the Pargi tile
-- normally, the Snorg tile when berserking, and the Parghit tile when mighted.
--
--     { mons = "Troll",
--       tileset = { { "default", "mons_pargi" },
--                   { "berserk", "mons_snorg" },
--                   { "mighty", "mons_parghit" } },
--       var_type = "status" },
--
-- The status names can be seen under the @ listing on the % screen, and
-- these are the short_text values from the duration_data[] array defined in
-- the source file duration-data.h. String value conditions are matched as
-- lua patterns, so substring matches and wildcards will work; see the lua
-- reference for details: http://www.lua.org/pil/20.2.html
