Constructor

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.

render(displayObject, matrix, clear)

This function will draw the display object to the RenderTexture.

In versions of Phaser prior to 2.4.0 the second parameter was a Phaser.Point object.
This is now a Matrix allowing you much more control over how the Display Object is rendered.
If you need to replicate the earlier behavior please use Phaser.RenderTexture.renderXY instead.

If you wish for the displayObject to be rendered taking its current scale, rotation and translation into account then either
pass null, leave it undefined or pass displayObject.worldTransform as the matrix value.

Parameters
Name Type Argument Default Description
displayObject Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Group

The display object to render to this texture.

matrix Phaser.Matrix <optional>

Optional matrix to apply to the display object before rendering. If null or undefined it will use the worldTransform matrix of the given display object.

clear boolean <optional>
false

If true the texture will be cleared before the display object is drawn.

Inherited From
Source code: gameobjects/RenderTexture.js (Line 117)

renderRawXY(displayObject, x, y, clear)

This function will draw the display object to the RenderTexture at the given coordinates.

When the display object is drawn it doesn't take into account scale, rotation or translation.

If you need those then use RenderTexture.renderXY instead.

Parameters
Name Type Argument Default Description
displayObject Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Group

The display object to render to this texture.

x number

The x position to render the object at.

y number

The y position to render the object at.

clear boolean <optional>
false

If true the texture will be cleared before the display object is drawn.

Inherited From
Source code: gameobjects/RenderTexture.js (Line 89)

renderXY(displayObject, x, y, clear)

This function will draw the display object to the RenderTexture at the given coordinates.

When the display object is drawn it takes into account scale and rotation.

If you don't want those then use RenderTexture.renderRawXY instead.

Parameters
Name Type Argument Default Description
displayObject Phaser.Sprite | Phaser.Image | Phaser.Text | Phaser.BitmapText | Phaser.Group

The display object to render to this texture.

x number

The x position to render the object at.

y number

The y position to render the object at.

clear boolean <optional>
false

If true the texture will be cleared before the display object is drawn.

Inherited From
Source code: gameobjects/RenderTexture.js (Line 57)

resize(width, height, updateBase)

Resizes the RenderTexture.

Parameters
Name Type Description
width Number

The width to resize to.

height Number

The height to resize to.

updateBase Boolean

Should the baseTexture.width and height values be resized as well?

Inherited From
Source code: pixi/textures/RenderTexture.js (Line 139)

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.

lineAlignment string <optional>
'left'

Align the text within this width. Set to RetroFont.ALIGN_LEFT (default), RetroFont.ALIGN_RIGHT or RetroFont.ALIGN_CENTER.

Source code: gameobjects/RetroFont.js (Line 275)

setFrame(frame)

Specifies the region of the baseTexture that this texture will use.

Parameters
Name Type Description
frame Rectangle

The frame of the texture to set it to

Inherited From
Source code: pixi/textures/Texture.js (Line 178)

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 code: gameobjects/RetroFont.js (Line 293)

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.
