Cocos Creator API

1.3.0

Cocos Creator is a highly customizable game development tool that utilizes the power of cocos2d-x.

View

: cc

cc.view is the singleton object which represents the game window.
It's main task include:

  • Apply the design resolution policy
  • Provide interaction with the window, like resize event on web, retina display support, etc...
  • Manage the game view port which can be different with the window
  • Manage the content scale and translation

    Since the cc.view is a singleton, you don't need to call any constructor or create functions,
    the standard way to use it is by calling:
  • cc.view.methodName();

setTargetDensityDPI
(
  • densityDPI
)

Sets view's target-densitydpi for android mobile browser. it can be set to:

  1. cc.macro.DENSITYDPI_DEVICE, value is "device-dpi"
  2. cc.macro.DENSITYDPI_HIGH, value is "high-dpi" (default value)
  3. cc.macro.DENSITYDPI_MEDIUM, value is "medium-dpi" (browser's default value)
  4. cc.macro.DENSITYDPI_LOW, value is "low-dpi"
  5. Custom value, e.g: "480"

densityDPI String

getTargetDensityDPI ( ) String

Returns the current target-densitydpi value of cc.view.

: String

resizeWithBrowserSize
(

)

Sets whether resize canvas automatically when browser's size changed.
Useful only on web.
enabled Boolean

Whether enable automatic resize with browser's resize event

setResizeCallback
(
  • callback
)

Sets the callback function for cc.view's resize action,
this callback will be invoked before applying resolution policy,
so you can do any additional modifications within the callback.
Useful only on web.
callback Function | Null

The callback function

setOrientation
(
  • orientation
)

Sets the orientation of the game, it can be landscape, portrait or auto. When set it to landscape or portrait, and screen w/h ratio doesn't fit, cc.view will automatically rotate the game canvas using CSS. Note that this function doesn't have any effect in native, in native, you need to set the application orientation in native project settings
orientation Number

Possible values: cc.macro.ORIENTATION_LANDSCAPE | cc.macro.ORIENTATION_PORTRAIT | cc.macro.ORIENTATION_AUTO

adjustViewPort
(
  • enabled
)

Sets whether the engine modify the "viewport" meta in your web page.

Only useful on web
enabled Boolean

Enable automatic modification to "viewport" meta

getFrameSize ( ) Size

Returns the frame size of the view.
On native platforms, it returns the screen size since the view is a fullscreen view.
On web, it returns the size of the canvas's outer DOM element.

:

: Size

setFrameSize
(
  • width
  • height
)

On native, it sets the frame size of view.
On web, it sets the size of the canvas's outer DOM element.
width Number

setDesignResolutionSize
(
  • width
  • height
  • resolutionPolicy
)

Sets the resolution policy with designed view size in points.
The resolution policy include:
[1] ResolutionExactFit Fill screen by stretch-to-fit: if the design resolution ratio of width to height is different from the screen resolution ratio, your game view will be stretched.
[2] ResolutionNoBorder Full screen without black border: if the design resolution ratio of width to height is different from the screen resolution ratio, two areas of your game view will be cut.
[3] ResolutionShowAll Full screen with black border: if the design resolution ratio of width to height is different from the screen resolution ratio, two black borders will be shown.
[4] ResolutionFixedHeight Scale the content's height to screen's height and proportionally scale its width

:

: Size

setRealPixelResolution
(
  • width
  • height
  • resolutionPolicy
)

Sets the container to desired pixel resolution and fit the game content to it. This function is very useful for adaptation in mobile browsers. In some HD android devices, the resolution is very high, but its browser performance may not be very good. In this case, enabling retina display is very costy and not suggested, and if retina is disabled, the image may be blurry. But this API can be helpful to set a desired pixel resolution which is in between. This API will do the following: 1. Set viewport's width to the desired width in pixel 2. Set body width to the exact pixel resolution 3. The resolution policy will be reset with designed view size in points.
width Number

Design resolution width.
height Number

Design resolution height.
resolutionPolicy ResolutionPolicy | Number

The resolution policy desired
