Crate let_engine

Re-exports

• pub use rapier2d;

Modules

• camera
  Camera and vision related settings.
• data
  Holds model related data structures like Vertices and premade models as well as a circle maker macro.
• directions
  Cardinal directions
• error
  All errors that can occur in this engine.
• events
  Events
• materials
  Material related settings that determine the way the scene gets rendered.
• objects
  Objects to be drawn to the screen.
• physics
  Physics related structs.
• prelude
  usage:
• resources
  Resources to be handled by the engine like textures, sounds and fonts.
• window

Macros

• color
• font
  Loads a font to the engine using binary true type font data of the inserted &[u8] and returns a Font.
• let_engine
  Initializes the let engine.
• make_circle
  A macro that makes it easy to create circles.
• material
  Loads a new material.
• model
  Loads a model to the engine using the vertex and index data of the inserted Data and returns a Model.
• raw_shader
  Loads a shader from glsl bytes. Takes &[u8] and returns Shaders. Those shaders can be used when making materials.
• start_engine
  Starts the engine, enables the window and starts drawing the scene. Takes a window::WindowBuilder for the initial window.
• texture
  Loads a texture to the engine using one of the supported file formats and returns a Texture.
• texture_from_raw
  Loads a texture to the engine using raw image bytes and context and returns a Texture.
• write_descriptor
  Describes a write operation for a descriptor. Used with materials to interact with custom shaders inside them.

Structs

• Color
  Color is a struct that represents a color.
• Game
  The struct that holds and executes all of the game data.
• Input
  Holds the input information to be used in game.
• Layer
  A layer struct holding it’s own object hierarchy, camera and physics iteration.
• Lazy
  A value which is initialized on the first access.
• Scene
  The whole scene seen with all it’s layers.
• Time
  Holds the timings of the engine like runtime and delta time.
• Transform
  Holds position size and rotation of an object.
• Vec2
  A 2-dimensional vector.
• Vertex

Functions

• tvert
  Creates a vertex with given x and y coordinates for position and given tx and ty coordinates for the UV texture mapping for those points.
• vec2
  Creates a 2-dimensional vector.
• vert
  Creates a vertex with given x and y coordinates for both position and texture position.

Type Aliases

• Mutex
  A mutual exclusion primitive useful for protecting shared data
• NObject
• WeakObject
• _Resources

Attribute Macros

• object
  Implements GameObject on a struct and automaically adds the fields transform, appearance, id and layer to update from and to. Also adds 2 functions. Update and Sync. Update updates the object from the layer system and sync syncs the object to the layer. Those functions panic when the object isn’t initialized to the layer yet.
