Macros§

add_wasm_support
embedded_resource
Declare an embedded resource.
link_resource
Link an embedded resource, making it available to bracket-lib via the resources system.
smallvec
Creates a SmallVec containing the arguments.

Structs§

AlphaLerp
Implements an Alpha-Only Lerp as an iterator
BACKEND
BACKEND_INTERNAL
BTerm
A BTerm context.
BTermBuilder
Provides a builder mechanism for initializing BTerm. You can chain builders together, and and with a call to .build(). This allows you to provide settings if you want to, or just use a simple initializer if you are in a hurry.
BTermInternal
BTermPlatform
Provides a base abstract platform for BTerm to run on, with specialized content.
Bresenham
Line-drawing iterator
BresenhamCircle
An implementation of [Bresenham’s circle algorithm]. [Bresenham’s circle algorithm]: http://members.chello.at/~easyfilter/bresenham.html Derived from the line_drawing crate, but specialized to use BTerm’s types.
BresenhamCircleNoDiag
A version of the Bresenham circle that does not make diagonal jumps
BresenhamInclusive
New type over Bresenham which include the end points when iterated over.
ColorPair
Represents two colors together, a foreground and a background. Frequently used to represent a glyph rendered on a console with a solid background color.
Degrees
Convenience type: you can define an angle in Degrees and it is convertible to Radians (and vice versa)
DiceIterator
DiceParseError
DiceType
DijkstraMap
Representation of a Dijkstra flow map. map is a vector of floats, having a size equal to size_x * size_y (one per tile). size_x and size_y are stored for overflow avoidance. max_depth is the maximum number of iterations this search shall support.
DisplayConsole
A display console, used internally to provide console render support. Public in case you want to play with it, or access it directly.
DrawBatch
Represents a batch of drawing commands, designed to be submitted together.
EMBED
FastNoise
FlexiConsole
A sparse console. Rather than storing every cell on the screen, it stores just cells that have data.
FlexiTile
Internal storage structure for sparse tiles.
Font
BTerm’s representation of a font or tileset file.
HSV
Represents an H/S/V triplet, in the range 0..1 (32-bit float) This can provide for a more natural color progression, and provides compatibility with HSV-based color systems.
HsvLerp
An HSV Lerp - transition from one HSV color to another in a set number of steps.
INPUT
InitHints
Input
Represents the current input state. The old key/mouse fields remain available for compatibility.
MultiTileSprite
Represents a sprite consisting of multiple glyphs/colors, occupying multiple console locations.
NavigationPath
Holds the result of an A-Star navigation query. destination is the index of the target tile. success is true if it reached the target, false otherwise. steps is a vector of each step towards the target, including the starting position.
OutOfSpace
Point
Helper struct defining a 2D point in space.
Point3
Helper struct defining a 2D point in space.
RGB
Represents an R/G/B triplet, in the range 0..1 (32-bit float)
RGBA
Represents an R/G/B triplet, in the range 0..1 (32-bit float)
Radians
Convenience type: you can define an angle in Radians and it is convertible to Degrees (and vice versa)
RandomNumberGenerator
Rect
Defines a two-dimensional rectangle.
RectF
Defines a rectangle with floating-point coordinates.
RenderSprite
Internal storage structure for sparse tiles.
RgbLerp
Implements an RGB Lerp as an iterator
RgbaLerp
Implements an RGBA Lerp as an iterator
Shader
SimpleConsole
A simple console with background color.
SmallVec
A Vec-like container that can store a small number of elements inline.
SparseConsole
A sparse console. Rather than storing every cell on the screen, it stores just cells that have data.
SparseTile
Internal storage structure for sparse tiles.
Sprite
SpriteConsole
A sparse console. Rather than storing every cell on the screen, it stores just cells that have data.
SpriteSheet
TextBlock
TextBuilder
Tile
The internal storage type for tiles in a simple console.
VectorLine
Define a line using a fast 2D vector. It may not be as pixel-perfect as Bresenham, but with vectorization it is sometimes faster for a quick line solution.
VirtualConsole
XpCell
Structure representing a character and its foreground/background color
XpColor
Structure representing the components of one color
XpFile
Structure representing a REXPaint image file which is a stack of layers
XpLayer
Structure representing a layer Cells are in the same order as in the file, in column-major order (index of position x,y is y*height + x).

Traits§

Algorithm2D
Implement these for handling conversion to/from 2D coordinates (they are separate, because you might want Dwarf Fortress style 3D!)
Algorithm3D
Implement these for handling conversion to/from 2D coordinates (they are separate, because you might want Dwarf Fortress style 3D!)
BaseMap
Implement this trait to support path-finding functions.
Console
Trait that must be implemented by console types.
GameState
Implement this trait on your state struct, so the engine knows what to call on each tick.

Functions§

a_star_search
Request an A-Star search. The start and end are specified as index numbers (compatible with your BaseMap implementation), and it requires access to your map so as to call distance and exit determinations.
add_named_colors_to_palette
Insert all named W3C colors into the palette
clear_command_buffer
Clears the global command buffer. This is called internally by BTerm at the end of each frame. You really shouldn’t need to call this yourself.
clear_palette
Empties the palette
draw_bar_horizontal
Draws a horizontal progress bar
draw_bar_vertical
Draws a vertical progress bar
draw_box
Draws a box, starting at x/y with the extents width/height using CP437 line characters
draw_box_double
Draws a box, starting at x/y with the extents width/height using CP437 line characters
draw_hollow_box
Draw a single-lined box without filling in the middle
draw_hollow_box_double
Draws a box, starting at x/y with the extents width/height using CP437 line characters
field_of_view
Calculates field-of-view for a map that supports Algorithm2D.
field_of_view_set
Calculates field-of-view for a map that supports Algorithm2D, returning a HashSet. This is a bit faster than coercing the results into a vector, since internally it uses the set for de-duplication.
init_raw
letter_to_option
For A-Z menus, translates the keys A through Z into 0..25
line2d
Plots a line between two 2D points and returns a vector of points along the line.
line2d_bresenham
Uses a Bresenham’s algorithm to plot a line between two points. On some CPUs, this is faster than Bresenham.
line2d_vector
Uses a 2D vector algorithm to plot a line between two points. On some CPUs, this is faster than Bresenham.
log
main_loop
Runs the BTerm application, calling into the provided gamestate handler every tick.
palette_color
Retrieve a palette color by name from the global registry. Returns Some(RGBA) if the color is registered, None if it is not.
parse_dice_string
project_angle
From a given start point, project forward radius units at an angle of angle_radians degrees. 0 Degrees is north (negative Y), 90 degrees is east (positive X)
register_palette_color
Register a palette color by name with the global registry.
render_draw_buffer
Submits the current batch to the BTerm buffer and empties it
string_to_cp437
Converts a string into a vector of u8, CP437 representations of the string
to_char
to_cp437
Converts a unicode character to a CP437 equivalent, returning 0 if it didn’t have a match
xp_to_console
Applies an XpFile to a given console, with 0,0 offset by offset_x and offset-y.
xp_to_draw_batch
Applies an XpFile to a given draw batch, with 0,0 offset by offset_x and offset-y.

Type Aliases§

BResult
FontCharType
GlCallback
PointF
