Add split-panels object

var splitPanels = scene.rexUI.add.splitPanels({
    // x: 0,
    // y: 0,

    // bottomPanel: topPanelGameObject,

    splitter: splitterGameObject,

    minLeftPanelWidth: 0,
    minTopPanelHeight: 0,

    minRightPanelWidth: 0,
    minBottomPanelHeight: 0,

    splitRatio: 0.5


    space: {
        left: 0, right: 0, top: 0, bottom: 0, item: 0,

        leftPanelTop: 0, leftPanelBottom: 0, leftPanelLeft: 0, leftPanelRight: 0,

    },

    // name: '',

});
  • x, y : Position of this object, it is valid when this object is the top object.
  • anchor : See anchor.
    • left, right, centerX, x, top, bottom, centerY, y : Position based on visible window, which composed of
      • Percentage of visible width/height : 'p%', p: 0 ~ 100.
        • 'left'(=0%), 'center'(=50%), 'right'(=100%)
        • 'top'(=0%), 'center'(=50%), 'bottom'(=100%)
      • Offset : '+n', or '-n'.
    • width, height : Set size (invoke onResizeCallback) based on visible window, which composed of
      • Percentage of visible width/height : 'p%', p: 0 ~ 100.
      • Padding : '+n', or '-n'.
    • onResizeCallback : A default resize callback will be assigned interanlly.
  • width, height : Minimum width, minimum height.
  • background : Game object of background, optional. This background game object will be resized to fit the size of label.
  • leftPanel(topPanel), rightPanel(bottomPanel) : First and second panel children.
  • splitter : Game object of splitter.
  • minLeftPanelWidth(minTopPanelHeight), minRightPanelWidth(minBottomPanelHeight) : Minimum width/height of first and second children.
    • 0 : Width/height does not have constraint. Default behavior.
  • splitRatio : Position of splitter. 0~1. Default value is 0.5.
  • space : Pads spaces.
    • space.left, space.right, space.top, space.bottom : Space of bounds.
    • space.item : Space between first child and splitter, splitter and second child.
    • space.leftPanelTop(space.topPanelTop), space.leftPanelBottom(space.topPanelBottom), space.leftPanelLeft(space.topPanelLeft), space.leftPanelRight(space.topPanelRight) : Space around first game object.
    • space.rightPanelTop(space.bottomPanelTop), space.rightPanelBottom(space.bottomPanelBottom), space.rightPanelLeft(space.bottomPanelLeft), space.rightPanelRight(space.bottomPanelRight) : Space around second game object.
    • space.splitterTop, space.splitterBottom, space.splitterLeft, space.splitterRight : Space around splitter game object.
  • name : Set name of this game object.
  • draggable : Set true to drag top-most object.
  • sizerEvents : Set true to fire sizer events. Default value is false.
  • enableLayer :
    • false : Add child game objects into scene's display list. Default behavior.
    • true : Add child game objects into an internal layer game object. See also.

Custom class

  • Define class
    class MySplitPanels extends RexPlugins.UI.SplitPanels {
        constructor(scene, config) {
            super(scene, config);
            // ...
            scene.add.existing(this);
        }
        // ...
    }
    
  • Create instance
    var splitPanels = new MySplitPanels(scene, config);
