#Tile(id = Undefined, nx: Undefined, dx: Undefined, ox: 0, ny: Undefined, dy: Undefined, oy: 0, proc: nil) { ... } ⇒ Sevgi::Graphics::Element

Builds a two-dimensional tile grid.

Parameters:

  • id (String) (defaults to: Undefined) —

    referenced template id

  • nx (Integer) (defaults to: Undefined) —

    number of columns

  • dx (Numeric) (defaults to: Undefined) —

    horizontal spacing

  • ox (Numeric) (defaults to: 0) —

    horizontal offset

  • ny (Integer) (defaults to: Undefined) —

    number of rows

  • dy (Numeric) (defaults to: Undefined) —

    vertical spacing

  • oy (Numeric) (defaults to: 0) —

    vertical offset

  • proc (Proc, nil) (defaults to: nil) —

    optional coordinate/customization proc

Yields:

  • evaluates the template drawing DSL in a generated group

Yield Returns:

  • (Object) —

    ignored block result

Returns:

Raises:

  • (Sevgi::ArgumentError) —

    when a required tile argument is missing or invalid
