class: BasePrepare


The prepare manager provides functionality to upload content to the GPU. BasePrepare handles
basic queuing functionality and is extended by {@link PIXI.prepare.WebGLPrepare} and {@link PIXI.prepare.CanvasPrepare}
to provide preparation capabilities specific to their respective renderers.

Subclass(es):

CanvasPrepare, WebGLPrepare, CanvasPrepare, WebGLPrepare

Methods


upload(item: function, PIXI.DisplayObject, PIXI.Container, PIXI.BaseTexture, PIXI.Texture, PIXI.Graphics, PIXI.Text, done: function): void

Upload all the textures and graphics to the GPU.

Params:

Name Type Attribute Description
item

Either the container or display object to search for items to upload, the items to upload themselves,
or the callback function, if items have been added using prepare.add.

done

Optional callback when all queued uploads have completed

Returns:

void


tick(): void

Handle tick update

Returns:

void


prepareItems(): void

Actually prepare items. This is handled outside of the tick because it will take a while
and we do NOT want to block the current animation frame from rendering.

Returns:

void


registerFindHook(addHook: function): PIXI.BasePrepare

Adds hooks for finding items.

Params:

Name Type Attribute Description
addHook

Function call that takes two parameters: item:*, queue:Array
function must return true if it was able to add item to the queue.

Returns:

PIXI.BasePrepare


registerUploadHook(uploadHook: function): PIXI.BasePrepare

Adds hooks for uploading items.

Params:

Name Type Attribute Description
uploadHook

Function call that takes two parameters: prepare:CanvasPrepare, item:* and
function must return true if it was able to handle upload of item.

Returns:

PIXI.BasePrepare


add(item: PIXI.DisplayObject, PIXI.Container, PIXI.BaseTexture, PIXI.Texture, PIXI.Graphics, PIXI.Text, *): PIXI.CanvasPrepare

Manually add an item to the uploading queue.

Params:

Name Type Attribute Description
item

Object to
add to the queue

Returns:

PIXI.CanvasPrepare


destroy(): void

Destroys the plugin, don't use after this.

Returns:

void


upload(item: function, PIXI.DisplayObject, PIXI.Container, PIXI.BaseTexture, PIXI.Texture, PIXI.Graphics, PIXI.Text, done: function): void

Adds hooks for uploading items.

Params:

Name Type Attribute Description
uploadHook

Function call that takes two parameters: prepare:CanvasPrepare, item:* and
function must return true if it was able to handle upload of item.

Returns:

PIXI.BasePrepare


add(item: PIXI.DisplayObject, PIXI.Container, PIXI.BaseTexture, PIXI.Texture, PIXI.Graphics, PIXI.Text, *): PIXI.CanvasPrepare

Manually add an item to the uploading queue.

Params:
