tetris_core

Simple Tetris game logic (with no interface)

WARNING: This project was created on an early stage of learning RUST. It might lack many good practices.

Usage:

• Use any drawing library. (i.e: piston_window)
• Use any randomizer library or method (i.e: rand)

As an example of implementation, you can check https://github.com/etoledom/rustpractice/blob/master/07tetris/src/main.rs

Implement the Randomizer trait rust struct Rand; impl Randomizer for Rand { fn random_between(&self, lower: i32, higher: i32) -> i32 { let mut rng = rand::thread_rng(); return rng.gen_range(lower, higher); } }

Instantiate a Tetris Game instance using an instance or your randomizer struct and the desired board size: rust let game_size = Size { height: 20, width: 10, }; let mut game = Game::new(&game_size, Box::new(rand));

update(&mut self, delta_time: f64)

Call game.update(delta_time); on every game loop.

draw(&self) -> Vec<Block>

Get the board model to be drawn: rust let game_blocks = game.draw();

A block is a structure that specifies the block's position, size and color in rgba. Position and size are unitary, you can give it the unit and size you want. struct Block { pub rect: Rect, pub color: Color, }

perform(&mut self, action: Action)

Perform movement and rotation actions rust game.perform(Action::Rotate);

is_game_over(&self) -> bool

Checks if is game over.

get_score(&self) -> u64

Gets the current score.
