Struct dcc_lsystem::turtle::BaseTurtle

pub struct BaseTurtle { /* fields omitted */ }

Implementations

impl BaseTurtle

pub fn new() -> Self

Creates a new BaseTurtle instance.

pub fn x(&self) -> i32

Returns the current x coordinate of the turtle.

pub fn y(&self) -> i32

Returns the current y coordinate of the turtle.

pub fn lines(&self) -> &[(i32, i32, i32, i32)]

Returns a slice containing all the lines (x1, y1, x2, y2) traversed by the turtle.

pub fn set_position(&mut self, x: i32, y: i32)

Set the current position of this turtle to (x,y).

pub fn delta_move(&mut self, dx: i32, dy: i32)

Moves the turtle by (dx,dy).

pub fn bounds(&self) -> (u32, u32, i32, i32)

Returns (total_width, total_height, min_x, min_y), where total_width (respectively total_height) is the largest horizontal (respectively vertical) distance between any two points that the turtle visited, min_x(respectivelymin_y`) is the smallest horizontal (respectively vertical) position that the turtle visited.

This is useful for converting from turtle coordinates to a new coordinate system starting at (0,0) with width total_width, height total_height, and all positions have positive x and y coordinates.

pub fn pen_down(&mut self)

Puts the turtles pen down.

pub fn pen_up(&mut self)

Pulls the turtles pen up.
