控制器#

介绍 #

IQ（第二代）Brain 可以连接到 IQ（第二代）或 IQ（第一代）控制器。两个控制器都配有两个模拟摇杆和多个按钮，Brain 可以使用它们来检测动作和按压。

For the examples below, the configured Distance Sensors will be named Controller, and will be used in all subsequent examples throughout this API documentation when referring to Controller class methods.

以下是可用方法的列表：

操作 - 启用或禁用控制器。

RemoteControlCodeEnabled – 启用或禁用控制器配置的操作。

Getters——从控制器操纵杆和按钮返回值。

pressing – 返回指定按钮是否被按下。
position – 返回操纵杆指定轴的位置。

回调——通过回调方法与控制器交互。

pressed – 按下指定按钮时调用一个函数。
released – 当指定按钮被释放时调用一个函数。
已更改 – 当操纵杆的轴发生变化时调用一个函数。

构造函数——手动初始化控制器。

controller – 创建一个控制器。

行动 #

RemoteControlCodeEnabled #

RemoteControlCodeEnabled is a variable that can be set to a Boolean that enables or disables Controller configured actions from the Devices menu. The controller is enabled by default. It can be set to either of the following:

true — Enable Controller configured actions.
false — Disable Controller configured actions.

Usage:
RemoteControlCodeEnabled = false;

pressing #

pressing returns an integer indicating whether a specific button on the controller is currently being pressed. This method must be called on a specific button object, such as ButtonEDown (see full list of button objects below).

1 - The specified button is being pressed.
0 - The specified button is not being pressed.

用法：
十个可用按钮对象之一可用于此方法，如下所示：

按钮	命令
`ButtonEDown`	`Controller.ButtonEDown.pressing()` — The E Down button
`ButtonEUp`	`Controller.ButtonEUp.pressing()` — The E Up button
`ButtonFDown`	`Controller.ButtonFDown.pressing()` — The F Down button
`ButtonFUp`	`Controller.ButtonFUp.pressing()` — The F Up button
`ButtonL3`	`Controller.ButtonL3.pressing()` — The Left Joystick button IQ (2nd gen) Controller only
`ButtonLDown`	`Controller.ButtonLDown.pressing()` — The L Down button
`ButtonLUp`	`Controller.ButtonLUp.pressing()` — The L Up button
`ButtonR3`	`Controller.ButtonR3.pressing()` — The Right Joystick button IQ (2nd gen) Controller only
`ButtonRDown`	`Controller.ButtonRDown.pressing()` — The R Down button
`ButtonRUp`	`Controller.ButtonRUp.pressing()` — The R Up button

参数	描述
	该方法没有参数。

position #

position returns the position of the joystick’s specified axis as an integer from –100 to 100, representing a percentage. This method must be called on a specific axis object, such as AxisA (see full list of axis objects below).

用法：
可以使用此方法的四个可用轴之一，如下所示：

轴	命令
`AxisA`	`Controller.AxisA.position()` — The Left Joystick’s vertical axis
`AxisB`	`Controller.AxisB.position()` — The Left Joystick’s horizontal axis
`AxisC`	`Controller.AxisC.position()` — The Right Joystick’s horizontal axis
`AxisD`	`Controller.AxisD.position()` — The Right Joystick’s vertical axis

参数	描述
	该方法没有参数。

`ButtonFDown`	`Controller.ButtonFDown.pressed(callback);` — The F Down button
`ButtonFUp`	`Controller.ButtonFUp.pressed(callback);` — The F Up button
`ButtonL3`	`Controller.ButtonL3.pressed(callback);` — The Left Joystick button IQ (2nd gen) Controller only
`ButtonLDown`	`Controller.ButtonLDown.pressed(callback);` — The L Down button
`ButtonLUp`	`Controller.ButtonLUp.pressed(callback);` — The L Up button
`ButtonR3`	`Controller.ButtonR3.pressed(callback);` — The Right Joystick button IQ (2nd gen) Controller only
`ButtonRDown`	`Controller.ButtonRDown.pressed(callback);` — The R Down button
`ButtonRUp`	`Controller.ButtonRUp.pressed(callback);` — The R Up button

范围	描述
`callback`	按下指定按钮时调用的回调函数。

// Example coming soon

released #

released registers a function to be called when a specific button on the controller is released. This method must be called on a specific button object, such as ButtonEDown – (see full list of button objects below).

用法：
十个可用按钮对象之一可用于此方法，如下所示：

按钮	命令
`ButtonEDown`	`Controller.ButtonEDown.released(callback);` — The E Down button
`ButtonEUp`	`Controller.ButtonEUp.released(callback);` — The E Up button
`ButtonFDown`	`Controller.ButtonFDown.released(callback);` — The F Down button
`ButtonFUp`	`Controller.ButtonFUp.released(callback);` — The F Up button
`ButtonL3`	`Controller.ButtonL3.released(callback);` — The Left Joystick button IQ (2nd gen) Controller only
`ButtonLDown`	`Controller.ButtonLDown.released(callback);` — The L Down button
