Functions

func ClearSurface

func ClearSurface(surf *gosdl.Surface)

Clears the specified surface, by setting everything to the transparent color

func ColorMap

func ColorMap(color color.RGBA) uint32

func FillRect

func FillRect(surf *gosdl.Surface, rect gosdl.Rect, color color.RGBA)

Helper function for coloring rectangles in surfaces. Allows us to use ordinary colors from image/color without hasslej

func Init

func Init(xres, yres int, debug bool) (*EventMgr, *DisplayMgr)

Initializes SDL and starts everything related to it. This must be called before other managers are initialized, since they rely on the functionality here. Also listens for the quit event and exits if we attempt to close the window

func LookupColor

func LookupColor(tc lib.TileColor, p Palette) color.RGBA

func MakeGrid

func MakeGrid(w, h int) *gosdl.Surface

Creates a grid that is meant to be directly overlayed on top of a board, so it's more apparent how the tetrominos are layed out. This is a static component, so the surface is returned directly

func NewSurface

func NewSurface(w, h int) *gosdl.Surface

Helper function for creating surfaces

func Rect

func Rect(x, y, w, h int) gosdl.Rect

Helper function for quickly making rects
