Runtime mapping of the axis button-press emulation configurations. Built in UIInteraction::InitializeAxisInputEmulations() based on the values retrieved from UIInputConfiguration.

AxisInputEmulation[MAX_SUPPORTED_GAMEPADS] Source code

Tracks the axis key-press emulation data for all players in the game.

AxisRepeatDelay Source code

The amount of time (in seconds) to wait between generating simulated button presses from axis input.

bCaptureUnprocessedInput Source code

Controls whether the UI system should prevent the game from recieving input whenever it's active. For games with interactive menus that remain on-screen during gameplay, you'll want to change this value to FALSE.

bDisableToolTips Source code

Globally enables/ disables widget tooltips.

bFocusedStateRules Source code

if this is TRUE, then focused widgets will not appear to become "active" when moused over - their appearance will remain "focused"

bFocusOnActive Source code

Controls whether widgets automatically receive focus when they become active. Set TRUE to enable this behavior.

bIsUIPrimitiveSceneInitialized Source code

TRUE if the scene for rendering 3d prims on this UI has been initialized

bProcessInput Source code

Indicates whether there are any active scenes capable of processing input. Set in UpdateInputProcessingStatus, based on whether there are any active scenes which are capable of processing input.

CanvasScene Source code

canvas scene for rendering 3d primtives/lights. Created during Init

DataStoreManager Source code

Manages all persistent global data stores. Created when UIInteraction is initialized using the value of GEngine.DataStoreClientClass.

DoubleClickPixelTolerance Source code

The maximum number of pixels to allow between the current mouse position and the last click's mouse position for a double-click event to be triggered

DoubleClickTriggerSeconds Source code

The maximum amount of time (in seconds) that can pass between a key press and key release in order to trigger a double-click event

MouseButtonRepeatDelay Source code

The amount of time (in seconds) to wait between generating repeat events for mouse buttons (which are not handled by windows).

MouseButtonRepeatInfo Source code

Tracks the mouse button that is currently being held down for simulating repeat input events.

SceneClient Source code

Acts as the interface between the UIInteraction and the active scenes.

SceneClientClass Source code

the class to use for the scene client

SupportedDoubleClickKeys Source code

list of keys that can trigger double-click events

ToolTipExpirationSeconds Source code

determines the number of seconds to display a tooltip before it will automatically be hidden

ToolTipInitialDelaySeconds Source code

determines how many seconds must pass after a tooltip has been activated before it is made visible

UIAxisMultiplier Source code

Mouse & joystick axis input will be multiplied by this amount in the UI system. Higher values make the cursor move faster.

UIInputConfig Source code

Singleton object which stores ui key mapping configuration data.

UIJoystickDeadZone Source code

The amount of movement required before the UI will process a joystick's axis input.

UISkinName Source code

The path name for the UISkin that should be used

UISoundCueNames Source code

The names of all UISoundCues that can be used in the game.

WidgetInputAliasLookupTable Source code

Runtime generated lookup table that maps a widget class to its list of input key aliases

UIAxisEmulationData Source code

Contains parameters for emulating button presses using axis input.
bEnabled:

Determines whether to emulate button presses.

UIKeyRepeatData Source code

Tracks information relevant to simulating IE_Repeat input events.
CurrentRepeatKey:

The name of the axis input key that is currently being held. Used to determine which type of input event to simulate (i.e. IE_Pressed, IE_Released, IE_Repeat)

NextRepeatTime:

The time (in seconds since the process started) when the next simulated input event will be generated.

CanPlayOnline Source code

@return Returns whether or not the specified player can play online.

CloseScene Source code

Removes the specified scene from the ActiveScenes array.
@param Scene the scene to deactivate
@return true if the scene was successfully removed from the ActiveScenes array

FindSceneByTag Source code

Searches through the ActiveScenes array for a UIScene with the tag specified
@param SceneTag the name of the scene to locate
@param SceneOwner the player that should be associated with the new scene. Will be assigned to the scene's PlayerOwner property.
@return pointer to the UIScene that has a SceneName matching SceneTag, or NULL if no scenes in the ActiveScenes stack have that name

GetDataStoreClient Source code

Returns a reference to the global data store client, if it exists.
@return the global data store client for the game.

GetLoginStatus Source code

@return Returns the current login status for the specified controller id.

GetNATType Source code

Wrapper for getting the NAT type

GetPlayerControllerId Source code

Retrieves the ControllerId for the player specified.
@param PlayerIndex the index [into the Engine.GamePlayers array] for the player to retrieve the ControllerId for
@return the ControllerId for the player at the specified index in the GamePlayers array, or INDEX_NONE if the index is invalid

GetPlayerCount Source code

Returns the number of players currently active.

GetPlayerIndex Source code

Retrieves the index (into the Engine.GamePlayers array) for the player which has the ControllerId specified
@param ControllerId the gamepad index of the player to search for
@return the index [into the Engine.GamePlayers array] for the player that has the ControllerId specified, or INDEX_NONE if no players have that ControllerId

GetTransientScene Source code

Get a reference to the transient scene, which is used to contain transient widgets that are created by unrealscript
@return pointer to the UIScene that owns transient widgets

HasLinkConnection Source code

@return Returns the current status of the platform's network connection.

IsLoggedIn Source code

@return Returns whether or not the specified player is logged in at all.

IsMenuLevel Source code

Determines whether a map is the default local map.
@param MapName if specified, checks whether MapName is the default local map; otherwise, checks the currently loaded map.
@return TRUE if the map is the default local (or front-end) map.

MergeScene Source code

Merge 2 existing scenes together in to one
@param SourceScene The Scene to merge
@param SceneTarget This optional param is the scene to merge in to. If it's none, the currently active scene will be used. RON: Fix me and remove the child version in UTGameInteraction

NotifyGameSessionEnded Source code

Called when the current map is being unloaded. Cleans up any references which would prevent garbage collection.

NotifyPlayerAdded Source code

Called when a new player has been added to the list of active players (i.e. split-screen join)
@param PlayerIndex the index [into the GamePlayers array] where the player was inserted
@param AddedPlayer the player that was added

NotifyPlayerRemoved Source code

Called when a player has been removed from the list of active players (i.e. split-screen players)
@param PlayerIndex the index [into the GamePlayers array] where the player was located
@param RemovedPlayer the player that was removed

OpenScene Source code

Adds the specified scene to the list of active scenes, loading the scene and performing initialization as necessary.
@param Scene the scene to open; if the scene specified is contained in a content package, a copy of the scene will be created and the copy will be opened instead.
@param SceneOwner the player that should be associated with the new scene. Will be assigned to the scene's PlayerOwner property.
@param OpenedScene the scene that was actually opened. If Scene is located in a content package, OpenedScene will be the copy of the scene that was created. Otherwise, OpenedScene will be the same as the scene passed in.
@return TRUE if the scene was successfully opened

PlayUISound Source code

Plays the sound cue associated with the specified name
@param SoundCueName the name of the UISoundCue to play; should corresond to one of the values of the UISoundCueNames array.
@param PlayerIndex allows the caller to indicate which player controller should be used to play the sound cue. For the most part, all sounds can be played by the first player, regardless of who generated the play sound event.
@return TRUE if the sound cue specified was found in the currently active skin, even if there was no actual USoundCue associated with that UISoundCue.

SetMousePosition Source code

Set the mouse position to the coordinates specified
@param NewX the X position to move the mouse cursor to (in pixels)
@param NewY the Y position to move the mouse cursor to (in pixels)

UIObject Source code

Create a temporary widget for presenting data from unrealscript
@param WidgetClass the widget class to create
@param WidgetTag the tag to assign to the widget.
@param Owner the UIObject that should contain the widget
@return a pointer to a fully initialized widget of the class specified, contained within the transient scene

UIScene Source code

Creates an instance of the scene class specified. Used to create scenes from unrealscript. Does not initialize the scene - you must call OpenScene, passing in the result of this function as the scene to be opened.
@param SceneClass the scene class to open
@param SceneTag if specified, the scene will be given this tag when created
@param SceneTemplate if specified, will be used as the template for the newly created scene if it is a subclass of SceneClass
@return a UIScene instance of the class specified
