About Engine

Engine is a simple framework to make 2D games in Ghost.

Status

Currently messing around with SDL and experimenting on what the API should look like.

Documentation

Website is currently in progress. You can find a local copy of some preliminary documentation here.

Requirements

Below are the requirements necessary if working with the Engine source code directly.

• SDL2
• SDL2_image
• SDL2_ttf

Requirements can be installed through brew on Mac:

$ brew install sdl2 sdl2_image sdl2_ttf

Notes

• Engine should come with a set of built-in "modules" to interact with and configure various aspects of the framework and game.

  • Audio

    The Audio module lets you play audio files such as music or sound effects.

  • Engine

    The Engine module allows you to control and configure various aspects of hoe Engine as an application operates.

  • Window

    The Window module provides utilities for retrieving and setting the state of the game window.

  • Graphics

    The Graphics module provides utilities for drawing to the screen.

  • Keyboard

    The Keyboard module allows you to retrieve the state of the keyboard.

  • Mouse

    The Mouse module allows you to retrieve the state of the mouse.

  • Controller

    The Controller module allows you to retrieve the state of game controllers.

Built In Functions

load()

Called only once before the game loop begins. This is where you would want to pre-load any resources, initialize variables, and configure settings. While its possible to perform these actions elsewhere in your code, its generally a better idea to do so here as its not called at every frame.

update()

Called continuously where calculations and other deterministic factors should be performed.

draw()

Much like update, this function is called continuously, allowing you to draw and update the screen.
