Implementations

impl BTerm

pub fn init_raw<S, T>( width_pixels: T, height_pixels: T, window_title: S, platform_hints: InitHints, ) -> Result<BTerm, Box<dyn Error + Send + Sync>>

where S: ToString, T: TryInto<u32>,

Initializes an OpenGL context and a window, stores the info in the BTerm structure.

pub fn init_simple8x8<S, T>( width_chars: T, height_chars: T, window_title: S, path_to_shaders: S, ) -> BTerm

where S: ToString, T: TryInto<u32>,

👎Deprecated since 0.6.2: Please migrate to the BTermBuilder system instead.

Quick initialization for when you just want an 8x8 font terminal

pub fn init_simple8x16<S, T>( width_chars: T, height_chars: T, window_title: S, path_to_shaders: S, ) -> BTerm

where S: ToString, T: TryInto<u32>,

👎Deprecated since 0.6.2: Please migrate to the BTermBuilder system instead.

pub fn register_console( &mut self, new_console: Box<dyn Console>, font_index: usize, ) -> usize

Registers a new console terminal for output, and returns its handle number.

pub fn register_console_no_bg( &mut self, new_console: Box<dyn Console>, font_index: usize, ) -> usize

Registers a new console terminal for output, and returns its handle number. This variant requests that the new console not render background colors, so it can be layered on top of other consoles.

pub fn register_fancy_console( &mut self, new_console: Box<dyn Console>, font_index: usize, ) -> usize

Registers a new console terminal for output, and returns its handle number. This variant requests that the new console not render background colors, so it can be layered on top of other consoles.

pub fn register_sprite_console( &mut self, new_console: Box<dyn Console>, ) -> usize

Registers a new Sprite-based console

pub fn set_active_console(&mut self, id: usize)

Sets the currently active console number.

pub fn mouse_pos(&self) -> (i32, i32)

Applies the current physical mouse position to the active console, and translates the coordinates into that console’s coordinate space.

pub fn mouse_point(&self) -> Point

Applies the current physical mouse position to the active console, and translates the coordinates into that console’s coordinate space.

Tells the game to quit

pub fn render_xp_sprite(&mut self, xp: &XpFile, x: i32, y: i32)

Render a REX Paint (https://www.gridsagegames.com/rexpaint/) file as a sprite. The sprite will be offset by offset_x and offset_y. Transparent cells will not be rendered.

pub fn to_xp_file(&self, width: usize, height: usize) -> XpFile

Saves the entire console stack to a REX Paint XP file. If your consoles are of varying sizes, the file format supports it - but REX doesn’t. So you may want to avoid that. You can also get individual layers with to_xp_layer.
