I am using one Subsystem that has methods for driving based on encoders and driving based on double input. I have been doing some scrounging and borrowed some code from various places.
the subsystem looks like this
DriveTrain
the commands used are DriveWithJoystick and DriveToDistance
DriveToDistance (this one doesnt do anything i commented out the autodrive part)
DriveWithJoysticks
Im stumped because when i deploy my code to the robot it gives a null pointer exception at the lines that reference the mechanum part
Code:
[cRIO] java.lang.NullPointerException
[cRIO] at us.mn.k12.fairmont.robotics.subsystems.DriveTrain.driveMechanum_Cartesian(DriveTrain.java:37)
[cRIO] at us.mn.k12.fairmont.robotics.commands.DriveWithJoysticks.execute(DriveWithJoysticks.java:25)
Anything else needed to solve the problem i can put into a pastebin but i dont know how to get around using the drive in 2 places.
