Struct Cursor 

pub struct Cursor {
    pub pos: Pos,
    pub blink_t: f32,
}

The cursor: a map tile and the time into its pulse.

Fields

pos: Pos

The tile under the cursor; always on the map.

blink_t: f32

Seconds into the current pulse, in 0..BLINK_PERIOD.

Implementations

impl Cursor

pub const fn new(pos: Pos) -> Self

A cursor on pos, at full brightness.

pub fn tick(&mut self, dt: f32)

Advances the pulse by dt seconds (negative or non-finite dt counts as zero).

pub fn brightness(&self) -> f32

Current brightness: 1 at the start of a pulse, down to BLINK_MIN halfway through, then back up (a cosine).

pub fn step(&mut self, dir: Dir, map_w: u16, map_h: u16) -> bool

Moves one tile dir, staying on a map_w × map_h map. Returns whether the cursor moved; a move restarts the pulse at full brightness, so the cursor is easy to follow.

pub fn jump(&mut self, pos: Pos)

Jumps to pos (e.g. the next unit), restarting the pulse.
