控制器#
介绍#
第二代 IQ 大脑可以连接到第二代 IQ 控制器或第一代 IQ 控制器。两个控制器都配有两个模拟摇杆和多个按钮Sensing/Brain.md大脑可以利用这些按钮来检测动作和按压。
This page uses Controller as the example controller name. Replace it with your own configured name as needed.
以下是所有方法的列表：
操作 — 开启或关闭控制器配置的操作。
RemoteControlCodeEnabled— Enables or disables controller configured actions.
获取器 — 返回控制器摇杆和按钮的值。
pressing— Returns whether the specified button is being pressed.position— Returns the position of the joystick’s specified axis.
回调——通过回调方法与控制器交互。
pressed— Registers a function to be called when the specified button is pressed.released— Registers a function to be called when the specified button is released.changed— Registers a function to be called when the joystick’s axis changes.
构造函数——手动初始化控制器。
controller— Create a controller.
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;
int main() {
// Initializing Robot Configuration. DO NOT REMOVE!
vexcodeInit();
// Drive forward or backward using the left joystick
RemoteControlCodeEnabled = false;
while (true) {
if (Controller.AxisA.position() > 0) {
Drivetrain.drive(forward);
} else if (Controller.AxisA.position() < 0) {
Drivetrain.drive(reverse);
// Press E ▲ to use the controller configured actions
} else if (Controller.ButtonEUp.pressing()) {
break;
} else {
Drivetrain.stop();
}
wait(20, msec);
}
RemoteControlCodeEnabled = true;
}
吸气剂#
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.

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).
