Elements

Align​

Align:Left -> symbol
Align:Center -> symbol
Align:Right -> symbol
Align:Justify -> symbol
VAlign:Top -> symbol
VAlign:Middle -> symbol
VAlign:Bottom -> symbol

These constants can be used to control the alignment of elements in the user interface. Normally they are used by a parameter called align or vAlign.

Animate​

Animate:FlyFromLeft -> symbol
Animate:FlyFromRight -> symbol
Animate:FlyFromTop -> symbol
Animate:FlyFromBottom -> symbol
Animate:Throb -> symbol

These constants can be used to animate content within the user interface. Normally they are used by a parameter called animate.

Color​

Color:Selected -> symbol
Color:Accent -> symbol
Color:Primary -> symbol
Color:Secondary -> symbol
Color:Hover -> symbol
Color:Positive -> symbol
Color:Negative -> symbol

Certain user interface functions accept these color symbols in place of a specific color value. These can be used to help maintain a consistent color scheme across the user interface.

PopoutFrom​

PopoutFrom:TopLeft -> symbol
PopoutFrom:TopRight -> symbol
PopoutFrom:BottomLeft -> symbol
PopoutFrom:BottomRight -> symbol

Used by the popoutFrom parameter of PopoutMenu to determine which corner the popout should appear from.

AutoClickIntent​

AutoClickIntent -> intent

Returns an intent to auto-click a particular button as soon as it appears in the user interface. This can be added to an array of intents passed into a Button to cause whatever other intents are attached to the button to occur automatically.

This can be used to auto-advance to the next game or screen automatically.

Auto-clicking only works for certain intents:

If the button has any other type of intent attached to it, nothing will happen.

The auto-clicking only occurs if the user could have actively done it themselves. The button must be visible, on the page, and not covered by any other UI elements (for example, no Modal dialogs). The user must also have touched the page at least once, and interacted with the page recently.

Blank​

Blank(width?=, height?, expand?, [ui])

  • width (Number): the width of the blank space, in em units.
  • height (Number): the height of the blank space, in em units.
  • expand (Boolean or Number): If set, expands the element to fill the remaining space of its container. If multiple elements have expand set, the remaining space will be apportioned according to the expand value of all elements in the container. A value of true is equivalent to 1.
  • ui (UI): the slot in the user interface where the blank space will be inserted.

Bookmark​

Bookmark<Id>(key?, [ui=])

Creates an invisible bookmark at the current position in the user interface. A ScrollToBookmarkIntent can be used to make a button scroll to a bookmark.

  • Id: an identifier for the bookmark.
  • key (any Keyable value): if the Id is not unique enough, you can provide an additional key to further distinguish the bookmark.
  • ui (UI): the slot in the user interface to place the bookmark.

Adds a button to the user interface. There are a number of styles to choose from:

  • Button, FlatButton, RaisedButton are standard buttons that and are intended for general interactive actions. RaisedButton looks more three dimensional and is best used for primary or important actions. FlatButton has rectangular corners and looks better on toolbars and menus. Buttons layout their contents horizontally, like an HStack.
  • Pip and PipMedal are glossy buttons that and are intended to be used as clickable image buttons, which is why they do not have any padding by default. PipMedal looks shiny and is best used to highlight something important or valuable. Pips/Medals layout their contents horizontally, like an HStack.
  • Link and SubtleLink are links that and are intended to be used for navigation to other pages. SubtleLink is less prominent and blends into the text until hovered over.

Parameters:

  • intent (Intent, String or Array of Intents/Strings): The action to take when the button is pressed. null (the default) means no action. The most common intent is a PressIntent. If provided a String, will attempt to parse as a URL to navigate to. It is possible to provide an array of multiple intents, which will be executed in order.

  • dismiss (Boolean): Whether the button should hide its current section of the user interface when pressed. This is equivalent to manually adding a DismissIntent.

  • autoClick (Boolean): If true, the button will be automatically clicked, as long as the player is actively looking at the window and has clicked or touched it at least once. This can be used to auto-advance to the next game automatically. This is equivalent to manually adding a AutoClickIntent, please read that section to learn more about the limitations of auto-clicking.

  • pointerPassthrough (Boolean): If true, hovering, clicking or tapping the button will go through to the game surface, causing the usual ButtonDown, ButtonUp, Pointer events.

  • tooltip (String): Text to display when hovering over the button.

  • fontSize (Number): The size of the text, measured in em units.

  • minWidth (Number): The minimum width of the button, in em units. If the button's content is smaller than this, the button will expand to this width.

  • minHeight (Number): The minimum height of the button, in em units. If the button's content is smaller than this, the button will expand to this height.

  • padding (Number): The inner padding of the stack, measured in em units. The content will be inset by this amount from the edges of the stack.

  • hPadding (Number): The padding on the left and right sides of the stack.

  • vPadding (Number): The padding on the top and bottom sides of the stack.

  • animation (Symbol): Animates the initial display of the tabbed selector. See Animate for a list of available animations.

  • ui (UI): the slot in the user interface to insert the tabs selector element.

The delve block will be called immediately to populate the tabs selector with options. It should contain one or more Tab calls, as well as a Selected call to designate which option is selected. Any other element types will be vertically stacked within the element.

ToggleDrawerIntent​

ToggleDrawerIntent -> intent

Creates an intent to toggle the open/close state of a Drawer in the user interface. Any Drawer elements within the same DrawerBoundary will be toggled. Attach the intent to a Button to trigger it.

Video​

Video(video, image?=, noControls?, width?, height?, expand?, stretch?, 
  cover?, shadow?, tooltip?, backgroundColor?, [ui])

Creates a background video element in the user interface. This will autoplay a video inline in the background on a loop. The video will always be muted. This element is best used as part of the background.

  • video (Asset): the video to display. Must be an asset, e.g. @fireball.mp4

  • image (Asset): the image to display while the video is loading or if the video is not available.

  • noControls (Boolean): If true, will hide the video controls that would normally allow the player to pause, play, and seek the video.

  • backgroundColor (Color): the color to display behind the video.

  • shadow (Number): the opacity of the drop shadow, from 0 (no shadow) to 1 (opaque shadow).

  • height (Number): the height of the video, in em units.

  • width (Number): the width of the video, in em units.

  • expand (Boolean or Number): If set, expands the element to fill the remaining space of its container. If multiple elements have expand set, the remaining space will be apportioned according to the expand value of all elements in the container. A value of true is equivalent to 1.

  • cover (Boolean): If true, will zoom the video until its shorter dimension fills the entire element.

  • stretch (Boolean): If true, will expand to fill the full cross-axis of its container. That is, if inside a VStack, will expand to full width, whereas if inside an HStack, will expand to full height.

  • tooltip (String): the text to display when the mouse hovers over the video.

  • ui (UI): the slot in the user interface where the video will be inserted.

VirtualJoystick​

VirtualJoystick(radius=, knobProportion?, backgroundColor?, borderRounding?, 
  knobColor?, shadow?, [ui]) |use ui| { }
VirtualJoystick2(radius=, knobProportion?, backgroundColor?, borderRounding?, 
  knobColor?, shadow?, [ui]) |use ui| { }

Adds a virtual joystick element to the user interface. The virtual joystick allows players who are using a touchscreen to send Joystick inputs even without a gamepad.

Parameters:

  • radius (Number): The radius of the outer ring of the virtual joystick, measured in em units.

  • knobProportion (Number): A value between 0 and 1 that determines how big the inner knob is relative to the outer ring. Defaults to 0.5.

  • backgroundColor (Color): The color of the outer ring of the virtual joystick.

  • knobColor (Color): The color of the inner knob of the virtual joystick.

  • borderRounding (Boolean or Number): Determines the roundness of the knob. If a Number is provided, determines the roundness of the knob in em units. If true (the default), makes the knob a circle.

  • shadow (Number): The opacity of the drop shadow of the inner knob.

  • ui (UI): The slot in the user interface where the layer will be inserted.

The Subblock will be called immediately to populate the contents of the inner knob of the virtual joystick. This could be a good place to display, for example, an image indicating that the player can interact with the joystick.

ZOverlay/ZUnderlay​

ZUnderlay(align?=, animate?, backgroundColor?, gap?, hPadding?, height?, 
  padding?, vAlign?, vPadding?, width?, [ui]) |use ui| { }
ZOverlay(align?=, animate?, backgroundColor?, gap?, hPadding?, height?, 
  padding?, vAlign?, vPadding?, width?, [ui]) |use ui| { }

Adds a layer element to the user interface. The element will be layered above or below the containing HStack or VStack that has zStack=true. If there is no containing HStack or VStack, the behavior is undefined. There are two styles:

  • ZUnderlay lays out its children below the other elements in the containing stack.
  • ZOverlay lays out its children above the other elements in the containing stack.

Both ZUnderlay and ZOverlay will lay out their children vertically.

Parameters:

  • backgroundColor (Color): The background color of the layer.

  • align (Symbol): The alignment of the contents of the layer. Valid options are Align:Left, Align:Center, Align:Right or null (the default).

  • vAlign (Symbol): The vertical alignment of the contents of the layer. Valid options are VAlign:Top, VAlign:Middle, VAlign:Bottom or null (the default).

  • animation (Symbol): The animation to use for the layer. See Animate for a list of available animations.

  • width (Number): The width of the layer, measured in em units.

  • height (Number): The height of the layer, measured in em units.

  • padding (Number): The inner padding of the layer, measured in em units. The content will be inset by this amount from the edges of the layer.

  • hPadding (Number): The padding on the left and right sides of the layer.

  • vPadding (Number): The padding on the top and bottom sides of the layer.

  • gap (Number): The gap between elements in the layer, measured in em units.

  • ui (UI): The slot in the user interface where the layer will be inserted.
