Module quicksilver::geom

A 2D geometry module

It contains basic shapes such as rectangles and circles, as well as vectors, lines, and a universal Shape API. It also has matrix-backed Transforms for arbitrary constant-time 2D transformations, such as rotating, scaling, or translating.

The Tilemap allows 2D storage of data in a world-like grid, and also moving objects at given speeds around the map, which is highly useful for games like platformers.

Structs

Circle	A circle with a center and a radius
Line	A line with a starting and end point
Rectangle	A rectangle with a top-left position and a size
Tile	An individual tile
Tilemap	A grid of Tile values
Transform	A 2D transformation represented by a matrix
Triangle	A triangle with three points
Vector	A 2D vector with an arbitrary numeric type

Traits

Scalar	A Scalar type that can be converted to a component of a Vector
Shape	The collision and positional attributes of shapes

Functions

about_equal	Find if two floating points are about equal
lerp	Linearly interpolate between two values
lerp_angle	Linearly interpolate between two angles, trying to find the shortest path
