When Phaser boots it will create an instance of this Texture Manager class.
It is a global manager that handles all textures in your game. You can access it from within
a Scene via the this.textures
property.
Its role is as a manager for all textures that your game uses. It can create, update and remove textures globally, as well as parse texture data from external files, such as sprite sheets and texture atlases.
Sprites and other texture-based Game Objects get their texture data directly from this class.

game | Phaser.Game |
The Phaser.Game instance this Texture Manager belongs to. |
The Game that the Texture Manager belongs to.
A game will only ever have one instance of a Texture Manager.
This object contains all Textures that belong to this Texture Manager.
Textures are identified by string-based keys, which are used as the property within this object. Therefore, you can access any texture directly from this object without any iteration.
You should not typically modify this object directly, but instead use the methods provided by the Texture Manager to add and remove entries from it.
The internal name of this manager.
If this flag is true
then the Texture Manager will never emit any
warnings to the console log that report missing textures.
An Image Game Object that belongs to this Texture Manager.
Used as a drawing stamp within Dynamic Textures.
This is not part of the display list and doesn't render.
The crop Rectangle as used by the Stamp when it needs to crop itself.
Adds a Texture Atlas to this Texture Manager.
In Phaser terminology, a Texture Atlas is a combination of an atlas image and a JSON data file, such as those exported by applications like Texture Packer.
It can accept either JSON Array or JSON Hash formats, as exported by Texture Packer and similar software.
As of Phaser 3.60 you can use this method to add a atlas data to an existing Phaser Texture.

Adds a new Texture to the Texture Manager created from the given Base64 encoded data.
It works by creating an Image
DOM object, then setting the src
attribute to
the given base64 encoded data. As a result, the process is asynchronous by its nature,
so be sure to listen for the events this method dispatches before using the texture.

Creates a Dynamic Texture instance and adds itself to this Texture Manager.
A Dynamic Texture is a special texture that allows you to draw textures, frames and most kind of Game Objects directly to it.
You can take many complex objects and draw them to this one texture, which can then be used as the base texture for other Game Objects, such as Sprites. Should you then update this texture, all Game Objects using it will instantly be updated as well, reflecting the changes immediately.
It's a powerful way to generate dynamic textures at run-time that are WebGL friendly and don't invoke expensive GPU uploads on each change.
See the methods available on the DynamicTexture
class for more details.
Optionally, you can also pass a Dynamic Texture instance to this method to have it added to the Texture Manager.

as the glTexture
parameter. You must now wrap the WebGLTexture
in a
WebGLTextureWrapper
instance before passing it to this method.

This is different to a Texture Atlas, created by tools such as Texture Packer, and more akin with the fixed-frame exports you get from apps like Aseprite or old arcade games.
As of Phaser 3.60 you can use this method to add a sprite sheet to an existing Phaser Texture.

Creates a new Texture using the given config values.
Generated textures consist of a Canvas element to which the texture data is drawn.
Generates a texture based on the given Create configuration object.
The texture is drawn using a fixed-size indexed palette of 16 colors, where the hex value in the data cells map to a single color. For example, if the texture config looked like this:
var star = [
'.....828.....',
'....72227....',
'....82228....',
'...7222227...',
'2222222222222',
'8222222222228',
'.72222222227.',
'..787777787..',
'..877777778..',
'.78778887787.',
'.27887.78872.',
'.787.....787.'
];
this.textures.generate('star', { data: star, pixelWidth: 4 });
Then it would generate a texture that is 52 x 48 pixels in size, because each cell of the data array
represents 1 pixel multiplied by the pixelWidth
value. The cell values, such as 8
, maps to color
number 8 in the palette. If a cell contains a period character .
then it is transparent.
The default palette is Arne16, but you can specify your own using the palette
property.

Removes a Texture from the Texture Manager and destroys it. This will immediately
clear all references to it from the Texture Manager, and if it has one, destroy its
WebGLTexture. This will emit a removetexture
event.
Note: If you have any Game Objects still using this texture they will start throwing errors the next time they try to render. Make sure that removing the texture is the final step when clearing down to avoid this.
