Struct rust_action_heroes::assets::game_level::LevelFormat

pub(crate) struct LevelFormat;

LevelFormat, like RonFormat, is a file format for storing data.

Amethyst requires I implement this to store custom meta-data.

I tried for a long time to store levels in Ron format, but storing an entire level in Ron was unweildy.

Instead I opted to write my own ascii-art level file format and write a parser for it. The parser just goes character by character and adds coordinates for different entity types to the GameLevel struct.

As an added bonus, you can write your own levels for Rust Action heroes pretty easiliy!

• W | w | # -> Wall
• H | h -> Prince horizontival the first
• V | v -> Duke vert the pure
• G | g -> Grabaron the wise
• C | c -> Crate
• E | e -> Exit
• K | k -> Key (for locks)
• L | l -> Locks (for keys)
• S | s -> Switch (for doors)
• D | d -> Door (for switches)
• | -> Floor

Example level

######
#g h #
# v s#####
#ksc  lde#
##########

This has all three playable characters, a crate, a key, a lock, a two switches, a door, and an exit. Is that level even beatable?

Trait Implementations

impl Clone for LevelFormat

fn clone(&self) -> LevelFormat

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for LevelFormat

impl Debug for LevelFormat

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for LevelFormat

fn default() -> LevelFormat

Returns the "default value" for a type.

impl Format<GameLevel> for LevelFormat

fn name(&self) -> &'static str

A unique identifier for this format.

fn import_simple(&self, bytes: Vec<u8>) -> Result<GameLevel, Error>

Produces asset data from given bytes. This method is a simplified version of format. This format assumes that the asset name is the full path and the asset is only contained in one file.

fn import(
    &self,
    name: String,
    source: Arc<dyn Source + 'static>,
    create_reload: Option<Box<dyn Format<D> + 'static>>
) -> Result<FormatValue<D>, Error>

Reads the given bytes and produces asset data.
