Ok, Ok, Ok!, now i understood!!!,
now work!!, the problem was very simple!,
i try with:
$tile[0].draw(@x, @y, 0)
and now works!!

Thanks for all the help!!

but i want to make:
@map[2][0].setId(block[:stone])

like that!.

i understood the first part...
like that:
require 'gosu'

$tile = Gosu::Image.load_tiles("res/tile.png", 16, 16)

class GameWindow < Gosu::Window
  def initialize()
    super(480, 480, false)
    self.caption = "Pix2D"
  end
  
  def update()
    #$level.tick()
  end

  def draw()
    #$level.render()
    $tile[0].draw(0,0,0)
  end

  def needs_cursor?
    true
  end
end

GameWindow.new.show

you can make an example with Code, a simple game with a tile?,
i'm from brazil, and i don't speak and read english good...

$ids = {
  :air => [0, 0],
  :dirt => [4, 0]
}

$w = 30
$h = $w

$level = Level.new(30, 30)

class Block
  def initialize(id, x, y)
    @id = id
    @x = x
    @y = y
  end
  def getId()
    return @id
  end
  def setId(id)
    @id = id
  end
  def tick()
  end
  def render()
    $tile.draw((@id[0]*$size), (@id[1]*$size), 0)
  end
end

def Level
  def initialize(w, h)
    @w = w
    @h = h
    @map = []
   
    initLevel()
  end
  def initLevel()
    @w.times() do |x|
      @map[x] = []
      @h.times() do |y|
        @map[x][y] = Block.new($ids[:air], x*$size, y*$size)
      end
    end
  end
  def tick()
  end
  def render()
    @w.times() do |x|
      @h.times() do |y|
        @map[x][y].render()
      end
    end
  end
end

class GameWindow < Gosu::Window

  end
 
  def needs_cursor?

end

Hello? someone can help-me?

Hello everyone!,

i like too much Ruby, and a want to create my game with gosu,
but my problem is:

i want to make a tile image with all Minecraft blocks,
and i use a hash for add the block in the game
like that:

$tile = {
  :air => [0,0]
}

and the air blocks was in the firt tile
of the Tileset!

but the gosu draws is:

image.draw(x, y)

i need this one:

drawImage( image, srcX, srcY, srcWidth, srcHeight, x, y, width, height, isCentred=false )

this class i want to draw:

class Block
    def new(id, x, y)
      @size = 16
        @id = id
        @x = x
        @y = y
        @w = @size
        @h = @w
    end
    def getId()
        return @id
    end
    def setId(id)
        @id = id
    end
    def getX()
        return @x
    end
    def getY()
        return @y
    end
    def render()
        if @id != $blocks[:air]
            drawImage( $tile,  @id[0]*@size, @id[1]*@size, @size, @size, @x, @y, @w, @h )
        end
    end
end

help me Please!,
thanks.
