Xbox Controller - How select right or left hand? - C++

Technical Programming
#1

Hello All,

I have been trying to use the Xbox Controller codes. I can’t to find the correct command to pick between left or right hand (klefthand or krighthand).

What am I supposed to put in the blank area below?

if(m_XboxDriverOne.GetBumperPressed(___________) == 1)

{m_LaunchMotorPower = m_LaunchMotorPower + .1;}

#2

what do you mean by right or left hand?

#3

In Java, that method takes a value of type Hand which is an enumeration with kLeft and kRight values (in GenericHID.java). I am not sure, but it looks like you might be using C++ in which case it take a value of type JoystickHand which is an enumeration with kLeftHand and kRightHand values (in GenericHID.h).

In either case, read the documentation for GetBumper and GetBumperPressed to understand the difference. I have seen several people use GetBumperPressed when they really wanted GetBumper.

There is a generic object “Hand” so you could call Hand.kLeft and Hand.kRight. At least this is how I did it last year.

#5

Left side or right side of the controller

#6

I just tried that. I VS code says the identifier “hand” is undefined.

#7

I am using C++. I want to use both GetBumper and GetBumperPressed. I just can’t seem pick left or right.

What goes in the parenthesis for left and right? .GetBumper(?)?

#8

It has been a while since I wrote C++, but either JoystickHand.kLeftHand or JoystickHand.kRightHand. You will need to import GenericHID.h.

#9

I just tried the joystickHand.kLeftHand. Did not work.

Here is what i’m looking at:

Did you import GenericHID.h?

#11

Yes

#12

Try GenericHID.JoystickHand.kLeftHand.

May want to find someone that has done C++ more recently than I, but that may do it.

#13

Didn’t work. Thanks for trying

I have a way around it. I just want to use the xbox controller code.

#14

we do this using this command
if(Driver.GetBumper(frc::XboxController::kRightHand) ==1)

Driver is the name of our Xbox Controller.

#15

Thanks for stepping in. My last major foray into C++ was pre-namespaces. This solution makes sense since XBoxContoller has GenericHID as its base class (look, I said base class instead saying extends).

#16

I’ll try that code when I’m back in the shop. Thank you
