Victors in reverse not responding.

[RoboTigers1796]

Hi there!
I'm one of the programming mentors for Team 1796 and we're encountering a problem with our Victors not responding when trying to go in reverse; the Victors respond moving forward. I've included a scaled down base code that still won't work. I know there must be something simple I'm missing...what is it??? Thanks in advance, everyone!

public class FRC2010Team1796 extends SimpleRobot {
private RobotDrive robotDrive = new RobotDrive(1,2);
private Joystick stickLeft = new Joystick(1);
private Joystick stickRight = new Joystick(2);
private AxisCamera cam;
private Victor claw1 = new Victor(3);
private Victor claw2 = new Victor(4);
private Victor arm1 = new Victor(5);
private Victor arm2 = new Victor(6);
private Compressor compressor = new Compressor(1,1);
private Solenoid armup = new Solenoid(7);
private Solenoid armdown = new Solenoid(8);


public FRC2010Team1796() {
getWatchdog().setExpiration(0.1);

compressor.start();


}

public void operatorControl() {
getWatchdog().setEnabled(false);

while (isEnabled() && isOperatorControl()) {
getWatchdog().feed();

if (stickRight.getRawButton(4)) {
claw1.set(-1.0);
claw2.set(-1.0);
} else {
claw1.set(0.0);
claw2.set(0.0);
}
if (stickRight.getTrigger()) {
claw1.set(1.0);
claw2.set(1.0);
} else {
claw1.set(0.0);
claw2.set(0.0);
}
if (stickRight.getRawButton(3)) {
claw1.set(-1.0);
claw2.set(1.0);
} else {
claw1.set(0.0);
claw2.set(0.0);
}
if (stickLeft.getRawButton(5)) {
arm1.set(1.0);
arm2.set(1.0);
} else {
arm1.set(0.0);
arm2.set(0.0);
}
if (stickLeft.getRawButton(4)) {
arm1.set(-1.0);
arm2.set(-1.0);
} else {
arm1.set(0.0);
arm2.set(0.0);
}
if (stickLeft.getTrigger()) {
armup.set(true);
} else {
armup.set(false);
}
if (stickLeft.getRawButton(3)) {
armdown.set(true);
} else {
armdown.set(false);
}
robotDrive.arcadeDrive(stickLeft);
}
//}
}
}


Thanks! We're really stuck here.

What do the LEDs on the Victors do when you command reverse?

[RoboTigers1796]

the LED's don't change (remains orange).

[Joe Ross]

If button 4 is pressed but not the trigger button, then claw 1 and 2 will be set to -1 and then immediately overwritten by 0 based on the trigger button if statement.

A nested if - else if - else structure is what you need.

of course! a million thank you's!!!!!
