ResolutionPolicy Class

Module: _decorator Parent Module: cc

cc.ResolutionPolicy class is the root strategy class of scale strategy, its main task is to maintain the compatibility with Cocos2d-x

Properties
  • EXACT_FIT Number The entire application is visible in the specified area without trying to preserve the original aspect ratio.
    Distortion can occur, and the application may appear stretched or compressed.
  • NO_BORDER Number The entire application fills the specified area, without distortion but possibly with some cropping,
    while maintaining the original aspect ratio of the application.
  • SHOW_ALL Number The entire application is visible in the specified area without distortion while maintaining the original
    aspect ratio of the application. Borders can appear on two sides of the application.
  • FIXED_HEIGHT Number The application takes the height of the design resolution size and modifies the width of the internal
    canvas so that it fits the aspect ratio of the device
    no distortion will occur however you must make sure your application works on different
    aspect ratios
  • FIXED_WIDTH Number The application takes the width of the design resolution size and modifies the height of the internal
    canvas so that it fits the aspect ratio of the device
    no distortion will occur however you must make sure your application works on different
    aspect ratios
  • UNKNOWN Number Unknow policy
Methods
  • constructor
  • preApply Manipulation before applying the resolution policy
  • apply Function to apply this resolution policy The return value is {scale: [scaleX, scaleY], viewport: {cc.Rect}}, The target view can then apply these value to itself, it's preferred not to modify directly its private variables
  • postApply Manipulation after appyling the strategy
  • setContainerStrategy Setup the container's scale strategy
  • setContentStrategy Setup the content's scale strategy
