#write_breaking(text, x, y, width, mode = :left, color = 0, alpha = 0xff, z_index = 0, scale_x = nil, scale_y = nil, line_spacing = nil) ⇒ Object

x

The horizontal reference for drawing the text. Works like in write_line for the :left, :right and :center modes. For the :justified mode, works the same as for :left.

y

The vertical reference for drawing the text. All text will be drawn from this point down.

width

The maximum width for the lines of text. Line is broken when this width is exceeded.

mode

The alignment of the text. Valid values are :left, :right, :center and :justified.

color

The color of the text, in hexadecimal RRGGBB format.

alpha

The opacity of the text. Valid values vary from 0 (fully transparent) to 255 (fully opaque).

z_index

The z-order to draw the object. Objects with larger z-orders will be drawn on top of the ones with smaller z-orders.

scale_x

The horizontal scaling of the text. If nil, this instance’s @scale_x value will be used.

scale_y

The vertical scaling of the text. If nil, this instance’s @scale_y value will be used.

line_spacing

The spacing between lines, in pixels. If nil, this instance’s @line_spacing value will be used.
