CB_Controllers

Static class to manage different controllers (gamepads, joysticks, remotes, etc.). It will return itself if it is tried to be instantiated. It uses gamepad-plus.

Source:
To Do:
  • Find a way to do button mapping (so we could use names as LEFT, RIGHT, etc.) and normalization for most web clients and gamepads (without forgetting proprietary ones as WII U, etc.).
  • Consider using always a numeric index instead of the ID of the gamepad (array instead of object), which could be a string, for CB_Controllers._gamepads (for optimization purposes).
  • Consider modifying CB_Controllers.isButtonDown function or add a new one to check whether any button (or axes) is down or not.

Methods

<static> getAxes( [gamepadId] [, gamepadIdNumeric] [, caseSensitive] [, avoidProprietary]) → {array}

Gets an array with information about the status of the axes of a given gamepad (or from all if none is given).

Parameters:
Name Type Argument Default Description
gamepadId integer | string <optional>
 ""

If an empty string is given, all gamepads available will be checked. Otherwise, it will only check the gamepad with the given ID or index (if any). When more than one gamepad is checked, the first axes values found which are not zero (0) will have priority.
gamepadIdNumeric boolean <optional>
 false|true

If the "gamepadId" parameter is an empty string, this parameter will be ignored. Otherwise, if the "gamepadId" parameter is not empty and this parameter is set to true, the gamepadId parameter will be converted to integer using "parseInt" internally. By default, this parameter is false unless the given "gamepadId" is numeric.
caseSensitive boolean <optional>
 false

Defines whether the "gamepadId" given should match the ID of the gamepad being case sensitive or not. This parameter will only be considered when the "gamepadIdNumeric" parameter is set to false.
avoidProprietary boolean <optional>
 CB_Configuration.CrossBase.CB_Controllers_avoidProprietary_DEFAULT

If set to true, proprietary gamepads will not be checked (performance will be faster).
Source:
Returns:

Returns an array with information about the status of the axes of a given gamepad (or from all if none is given).

Type
array

<static> getAxesDown( [gamepadId] [, minimumValue] [, maximumValue] [, gamepadIdNumeric] [, caseSensitive] [, avoidProprietary]) → {Object}

Gets an array with the axes pressed of a given gamepad (or from all if none is given). If more than one gamepad is pressing the same axis, it will return the value of the first one found.

Parameters:
Name Type Argument Default Description
gamepadId integer | string <optional>
 ""

If an empty string is given, all gamepads available will be checked. Otherwise, it will only check the gamepad with the given ID or index (if any).
minimumValue float <optional>
 0.5

The minimum value (included) that the checked axis or axes must have to consider them to be pressed.
maximumValue float <optional>
 1|-0.5

The maximum value (included) that the checked axis or axes must have to consider them to be pressed. The default value will be -0.5 if the given "minimumValue" is negative or zero (0) or it will be 1 otherwise.
gamepadIdNumeric boolean <optional>
 false|true

If the "gamepadId" parameter is an empty string, this parameter will be ignored. Otherwise, if the "gamepadId" parameter is not empty and this parameter is set to true, the gamepadId parameter will be converted to integer using "parseInt" internally. By default, this parameter is false unless the given "gamepadId" is numeric.
caseSensitive boolean <optional>
 false

Defines whether the "gamepadId" given should match the ID of the gamepad being case sensitive or not. This parameter will only be considered when the "gamepadIdNumeric" parameter is set to false.
avoidProprietary boolean <optional>
 CB_Configuration.CrossBase.CB_Controllers_avoidProprietary_DEFAULT

If set to true, proprietary gamepads will not be checked (performance will be faster).
Source:
Returns:

Returns an array with the axes pressed of a given gamepad (or from all if none is given). If more than one gamepad is pressing the same axis, it will return the value of the first one found.

Type

gamepadIdNumeric boolean <optional>
 false|true

Otherwise, if the "gamepadId" parameter is not empty and this parameter is set to true, the gamepadId parameter will be converted to integer using "parseInt" internally. By default, this parameter is false unless the given "gamepadId" is numeric.
caseSensitive boolean <optional>
 false

Defines whether the "gamepadId" given should match the ID of the gamepad being case sensitive or not. This parameter will only be considered when the "gamepadIdNumeric" parameter is set to false.

If set to true, proprietary gamepads will not be checked (performance will be faster).
Source:
Returns:

Type
Object

Gets an object with the buttons pressed of a given gamepad (or from all if none is given).

Parameters:
Name Type Argument Default Description
gamepadId integer | string <optional>
 ""

If an empty string is given, all gamepads available will be checked. Otherwise, it will only check the gamepad with the given ID or index (if any).
gamepadIdNumeric boolean <optional>
 false|true

Source:
Returns:

Returns an object with the buttons pressed of a given gamepad (or from all if none is given).

Type
Object

<static> getGamePads( [avoidProprietary]) → {Object}

Returns an object with the current gamepad objects, if any (using the GamePad API for non-proprietary gamepads).

Parameters:
Name Type Argument Default Description
avoidProprietary boolean <optional>
 CB_Configuration.CrossBase.CB_Controllers_avoidProprietary_DEFAULT

If set to true, proprietary gamepads which do not use the GamePad API (as WII, WI U gamepads, etc.) will not be included in the returning object and it will only include the ones detected by the GamePad API. Otherwise, if set to true, the returning object will contain one property called "standard" which will contain an object with the "gamepads" property with the gamepad objects that use the GamePad API and possibly different properties (one per each proprietary system) and inside of them an object with the "gamepads" property and maybe also other properties for other kind of devices which will include the status objects of those devices for each proprietary system. For gamepads that support the GamePad API, the indexes will be the identifier for each gamepad and the value its gamepad object. For proprietary gamepads, it will contain the returning value of the "getGamePads" function of each proprietary API.
Source:
To Do:
  • The proprietary ones should return better-normalized values to simulate the GamePad API.
Returns:

Returns an object with the current gamepad objects, if any (using the GamePad API for non-proprietary gamepads).
