Controller 1

joy1_Buttons

TPCJoystick joy1_Buttons

(TPCJoystick) Returns a "Bit Map" for the 12 buttons on Controller #1. For more information on how to use buttons to control actions, See the "Using Buttons" help section.

while(true) // infinite loop: { getJoystickSettings(joystick); // update buttons and joysticks   if(joystick.joy1_Buttons == 32) // if Button 6 is pressed on joy1: { motor[motorA] = 50; // motorA is run at a power level of 50 } }

joy1_TopHat

TPCJoystick joy1_TopHat

(TPCJoystick) Returns the value of the direction pad (or "Top Hat") on Controller #1. A value of -1 is returned when nothing is pressed, and a value of 0 to 7 for selected "octant" when pressed.

while(true) // infinite loop: { getJoystickSettings(joystick); // update buttons and joysticks   if(joystick.joy1_TopHat == 0) // if the topmost button on joy1's D-Pad ('TopHat') is pressed: { motor[motorA] = 50; // motorA is run at a power level of 50 } }

joy1_x1

TPCJoystick joy1_x1

(TPCJoystick) Value of the X Axis on the Left Joystick on Controller #1. Ranges in values between -128 to +127.

while(true) // infinite loop: { getJoystickSettings(joystick); // update buttons and joysticks motor[motorB] = joystick.joy1_x1; // motorB's powerlevel is set to the left stick's current x-value }

joy1_y1

TPCJoystick joy1_y1

(TPCJoystick) Value of the Y Axis on the Left Joystick on Controller #1. Ranges in values between -128 to +127.

while(true) // infinite loop: { getJoystickSettings(joystick); // update buttons and joysticks motor[motorB] = joystick.joy1_y1; // motorB's powerlevel is set to the left stick's current y-value }

joy1_x2

TPCJoystick joy1_x2

(TPCJoystick) Value of the X Axis on the Right Joystick on Controller #1. Ranges in values between -128 to +127.

while(true) // infinite loop: { getJoystickSettings(joystick); // update buttons and joysticks motor[motorB] = joystick.joy1_x2; // motorB's powerlevel is set to the right stick's current x-value }

joy1_y2

TPCJoystick joy1_y2

(TPCJoystick) Value of the Y Axis on the Right Joystick on Controller #1. Ranges in values between -128 to +127.

while(true) // infinite loop: { getJoystickSettings(joystick); // update buttons and joysticks motor[motorB] = joystick.joy1_y2; // motorB's powerlevel is set the right stick's current y-value }

Controller 2
