Functions

func DrawImage

func DrawImage(windowWidth, windowHeight int, img image.Image, imageRect Rect)

DrawImage draws an image to a GLFW window. You must have initialized glfw and gl before using this function and created a window

func InCircle

func InCircle(aCircle Circle, xPos, yPos int) bool

func InRect

func InRect(aRect Rect, xPos, yPos int) bool

useful for mouse events

func NewWindow

func NewWindow(width, height int, title string, resizable bool) *glfw.Window

NewWindow begins with initializing glfw and gl libraries.
