Member Function Documentation

◆ DoesSupportDragHandOff()

virtual bool UiInteractableInterface::DoesSupportDragHandOff ( AZ::Vector2 startPoint )

inlinevirtual

Returns true if this interactable supports taking active status when a drag is started on a child interactble AND the given drag startPoint would be a valid drag start point

Parameters

point,the start point of the drag (which would be on a child interactable) (viewport space)

◆ HandleAutoActivation()

virtual bool UiInteractableInterface::HandleAutoActivation ( )

inlinevirtual

Called when the interactable was navigated to via gamepad/keyboard, and auto activation is enabled on the interactable

Returns: true if the interactable handled the event

◆ HandleEnterPressed()

virtual bool UiInteractableInterface::HandleEnterPressed ( bool & shouldStayActive )

inlinevirtual

Called on an interactable component when an enter pressed event is received

Parameters

shouldStayActive,output - true if the interactable wants to become the active element for the canvas

Returns: true if the interactable handled the event

◆ HandleEnterReleased()

virtual bool UiInteractableInterface::HandleEnterReleased ( )

inlinevirtual

Called on the currently pressed interactable component when an enter released event is received

Returns: true if the interactable handled the event

◆ HandleKeyInputBegan()

virtual bool UiInteractableInterface::HandleKeyInputBegan	(	const AzFramework::InputChannel::Snapshot &	inputSnapshot,
		AzFramework::ModifierKeyMask	activeModifierKeys
	)

inlinevirtual

Called on the currently active interactable component when input is received

Returns: true if the interactable handled the event

◆ HandleMultiTouchPressed()

virtual bool UiInteractableInterface::HandleMultiTouchPressed	(	AZ::Vector2	point,
		int	multiTouchIndex
	)

pure virtual

Called on an interactable component when a multi-touch pressed event is received over it

Parameters

point,the	point at which the event occurred (viewport space)
multiTouchIndex,the	index of the multi-touch (the 'primary' touch with index 0 is sent to HandlePressed)

Returns: true if the interactable handled the event

◆ HandleMultiTouchReleased()

virtual bool UiInteractableInterface::HandleMultiTouchReleased	(	AZ::Vector2	point,
		int	multiTouchIndex
	)

pure virtual

Called on the currently pressed interactable component when a multi-touch release event is received

Parameters

point,the	point at which the event occurred (viewport space)
multiTouchIndex,the	index of the multi-touch (the 'primary' touch with index 0 is sent to HandlePressed)

Returns: true if the interactable handled the event

◆ HandlePressed()

virtual bool UiInteractableInterface::HandlePressed	(	AZ::Vector2	point,
		bool &	shouldStayActive
	)

pure virtual

Called on an interactable component when a pressed event is received over it

Parameters

point,the	point at which the event occurred (viewport space)
shouldStayActive,output	- true if the interactable wants to become the active element for the canvas

Returns: true if the interactable handled the event

◆ HandleReleased()

virtual bool UiInteractableInterface::HandleReleased ( AZ::Vector2 point )

pure virtual

Called on the currently pressed interactable component when a release event is received

Parameters

point,the point at which the event occurred (viewport space)

Returns: true if the interactable handled the event

◆ HandleTextInput()

virtual bool UiInteractableInterface::HandleTextInput ( const AZStd::string & textUTF8 )

inlinevirtual

Called on the currently active interactable component when text input is received

Returns: true if the interactable handled the event

◆ InputPositionUpdate()

virtual void UiInteractableInterface::InputPositionUpdate ( AZ::Vector2 point )

inlinevirtual

Called on the currently active interactable component when a mouse/touch position event is received

Parameters

point,the current mouse/touch position (viewport space)

◆ MultiTouchPositionUpdate()

virtual void UiInteractableInterface::MultiTouchPositionUpdate	(	AZ::Vector2	point,
		int	multiTouchIndex
	)

inlinevirtual

Called on the currently pressed interactable component when a multi-touch position event is received

Parameters

point,the	current mouse/touch position (viewport space)
multiTouchIndex,the	index of the multi-touch (the 'primary' touch with index 0 is sent to HandlePressed)

◆ OfferDragHandOff()

virtual bool UiInteractableInterface::OfferDragHandOff	(	AZ::EntityId	currentActiveInteractable,
		AZ::Vector2	startPoint,
		AZ::Vector2	currentPoint,
		float	dragThreshold
	)

inlinevirtual

Called on a parent of the currently active interactable element to allow interactables that contain other interactables to support drags that start on the child. If this return true the hand-off occured and the caller will no longer be considered the active interactable by the canvas.

Parameters

currentActiveInteractable,the	child element that is the currently active interactable
startPoint,the	start point of the potential drag (viewport space)
currentPoint,the	current points of the potential drag (viewport space)
