type DynaText

type DynaText struct {
	Color sdl.Color

	X      int32
	Y      int32
	Width  int32
	Height int32
	// contains filtered or unexported fields
}

func NewDynaText(font *Font, renderer *sdl.Renderer, color sdl.Color) *DynaText

NewDynaText creates a Text object.

func (*DynaText) Destroy

func (t *DynaText) Destroy()

Destroy closes the Text

func (*DynaText) Draw

func (t *DynaText) Draw(text string)

Draw renders text

func (*DynaText) DrawAt

func (t *DynaText) DrawAt(x, y int32, text string)

DrawAt renders text at the specified position

type Font

type Font struct {
	// contains filtered or unexported fields
}

Font wraps the SDL TTF fonts.

func NewFont

func NewFont(fontPath string, size int) *Font

type IViewer

type IViewer interface {
	// Open(IHost)
	Open()
	Run()
	Close()
	Quit()
	Configure()
	SetFont(fontPath string, size int)
}

func NewViewer

func NewViewer() IViewer

NewViewer creates a new viewer and initializes it.

type Text

type Text struct {
	Bounds sdl.Rect
	// contains filtered or unexported fields
}

Text represents a text texture for rendering.

func NewText
