switching the x & y on joy stick

[/*P4bl0*/]

hello i been trying to get the holonomicDrive working right for some time now i just want to get the joy stick to switch its x & y input and i cant get in to the joystick source code and change it plz some one help me

Can't you just reverse how you are implementing the axes in your code?

For example, if you are setting variable "velocity" to the y-axis, just set it to the x axis instead.

Alternatively, you could create new variables such as "newX" and set the actual y-axis to newX.

ok i may be saying some thing wrong or i dont get what your saying (this is my first year mostly alone on getting this to work) ok i have this

m_robotDrive.holonomicDrive(m_rightStick.getMagnit ude(), m_rightStick.getDirectionDegrees(), m_leftStick.getX());

in the code and its the only places i have the joystick input i dont want to change the left stick at all i tried swiching m_rightStick.getMagnitude() and m_rightStick.getDirectionDegrees() but it goes hay wire and i did not change anything else.

were using mecanum wheels and i have them on inputs of

front
4 2
1 3
back

some how it works but i just have the x and y mest up ..
i might be giving random info and not making any scenes

I haven't looked at the default holonomic code this year, but from that code it looks as though the holonomic drive function is expecting you to use a 3-axis joystick.
m_rightStick.getMagnitude() would be the y-direction
m_rightStick.getDirectionDegrees() would be the "twist" of the joystick
m_leftStick.getX() would, of course, be the x direction.

Are you using a 3-joystick set up? If not, then you will need to use a different holonomic drive method. If so, then all you should have to do is switch getMagnitute() and getX(). Thus the line would read-

m_robotDrive.holonomicDrive(m_leftStick.getX(), m_rightStick.getDirectionDegrees(), m_rightStick.getMagnitude());

no were using 2 logtech atk 3 joysticks witch you cant twist the joystick and changing

m_rightStick.getMagnitude()

to

m_rightStick.getX()

just disable are y axis from the right joy stick

sorry i read the code wrong i did not see you switch something else

[Bryan Herbst]

Well since you do not have a 3-axis joystick you need to send something other than m_rightStick.getDirectionDegrees().

And wow, sorry, I just realized that you already have two different joysticks there. My bad! In any case, they still wont be able to give you a degree measurement.

Is the second parameter just a float (does getDirectionDegrees() return an int from 0 to 360 or a float from -1 to 1)? If so, I would replace m_rightStick.getDirectionDegrees() with m_rightStick.getX()
