Class: RetroFont

Phaser. RetroFont

Phaser.RetroFont

new RetroFont(game, key, characterWidth, characterHeight, chars, charsPerRow, xSpacing, ySpacing, xOffset, yOffset)

A Retro Font is similar to a BitmapFont, in that it uses a texture to render the text. However unlike a BitmapFont every character in a RetroFont is the same size. This makes it similar to a sprite sheet. You typically find font sheets like this from old 8/16-bit games and demos.

setFixedWidth(width, lineAlignment)

If you need this RetroFont to have a fixed width and custom alignment you can set the width here. If text is wider than the width specified it will be cropped off.

Parameters:
Name Type Argument Default Description
width number

Width in pixels of this RetroFont. Set to zero to disable and re-enable automatic resizing.

setText(content, multiLine, characterSpacing, lineSpacing, lineAlignment, allowLowerCase)

A helper function that quickly sets lots of variables at once, and then updates the text.

Parameters:
Name Type Argument Default Description
content string

The text of this sprite.
multiLine boolean <optional>
 false

Set to true if you want to support carriage-returns in the text and create a multi-line sprite instead of a single line.
characterSpacing number <optional>
 0

To add horizontal spacing between each character specify the amount in pixels.
lineSpacing number <optional>
 0

To add vertical spacing between each line of text, set the amount in pixels.
lineAlignment string <optional>
 'left'

Align each line of multi-line text. Set to RetroFont.ALIGN_LEFT, RetroFont.ALIGN_RIGHT or RetroFont.ALIGN_CENTER.
allowLowerCase boolean <optional>
 false

Lots of bitmap font sets only include upper-case characters, if yours needs to support lower case then set this to true.
Source:

updateOffset(xOffset, yOffset)

Updates the x and/or y offset that the font is rendered from. This updates all of the texture frames, so be careful how often it is called. Note that the values given for the x and y properties are either ADDED to or SUBTRACTED from (if negative) the existing offsetX/Y values of the characters. So if the current offsetY is 8 and you want it to start rendering from y16 you would call updateOffset(0, 8) to add 8 to the current y offset.

Parameters:
Name Type Argument Default Description
xOffset number <optional>
 0

If the font set doesn't start at the top left of the given image, specify the X coordinate offset here.
yOffset number <optional>
 0

If the font set doesn't start at the top left of the given image, specify the Y coordinate offset here.
