Game's all possible states.

Widgets::update() takes care of proper state transformation.

Variants

MainMenu

Display the main menu.

Main menu contains a Start button, a button to Display Highscores, an Exit button.

Can transform into:

• ChooseDifficulty
• DisplayHighscores
• Exit

ChooseDifficulty

Display the screen where the player chooses the difficulty.

The screen contains one button for each difficulty and the Back button.

Can transform into:

• Playing
• MainMenu

Playing

The game is currently in progress.

This also contains the game's difficulty, the player's current score and whether the current fruit is a mango.

Can transform into GameOver.

Fields of Playing

difficulty: Difficulty	The game difficulty, as chosen in the ChooseDifficulty stage.
score: u64	The user's current score.
fruit: Option<usize>	The current fruit index. If None - it's a mango, else it's an index of fruit from util::FRUITS.

GameOver

The game was lost after a valiant battle.

Contains the game's difficulty, the player's final score and the Back button.

In this stage the player enters its name.

Can transform into:

• GameEnded
• MainMenu

Fields of GameOver

difficulty: Difficulty	The game difficulty, as same as in the Playing stage.
score: u64	The user's final score.
name: String	The user's name, mostly partial.

GameEnded

The game cycle has ended. Semi-meta-state

Contains the game's difficulty and the players final score.

In this stage the player enters its name.

Transforms into MainMenu.

Fields of GameEnded

name: String	The user's name.
score: u64	User's final score, weighted.

LoadLeaderboard

Meta-state indicating that the leaderboard needs to be loaded.

Needs to be handled in usercode, place the leaderboard into DisplayLeaderboard after loading it.

Leaderboards are loaded via Leader::load().

Transforms into DisplayLeaderboard

DisplayLeaderboard(Vec<Leader>)

Display top 10 high scores.

This screen also contains the Back button.

Can transform into MainMenu

Exit

Pseudo-state, signifying that the game window should be closed.

Can transform into: nothing. This is the final state all others seek.

Methods

impl GameState

pub fn should_exit(&self) -> bool

Check whether this state currently means that the game has ended.

Examples

assert!(GameState::Exit.should_exit());

pub fn should_load_leaderboard(&self) -> bool

Check whether this state requires usercode to load the leaderboard.

Examples

assert!(GameState::LoadLeaderboard.should_load_leaderboard());

Trait Implementations

impl Debug for GameState

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for GameState

fn clone(&self) -> GameState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq for GameState

fn eq(&self, __arg_0: &GameState) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &GameState) -> bool

This method tests for !=.

impl Eq for GameState

impl PartialOrd for GameState

fn partial_cmp(&self, __arg_0: &GameState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &GameState) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, __arg_0: &GameState) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, __arg_0: &GameState) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, __arg_0: &GameState) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for GameState

fn cmp(&self, __arg_0: &GameState) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.
