Post LEGO MOTOR ENCODERS
Hi

I am kind of new to programming but i'm getting the hang of it now. I have one problem that I haven't been able to solve. i have an Nxt motor. I want to be able to press a button on the joystick, and while it is pressed i want the motor to move to a certain position. Yet if i let go of the motor i want it to stop moving. If i keep pressing the button I want it to get to its limit position. Once it gets to the limit position, even if i am pressing the button, i want it to stop. The limit position is just a variable number. How can I go about doing this? I have tried to use the sample code given in Robot C for lego motors and I have tried to modify it but i just cant seem to get it to work. I would really appreciate your help. Thank You

I don't have RobotC in front of me, so some of the functions may be wrong, but it looks something like this:
Code:
nMotorEncoder[motorA] = 0;
while (true)
{
    if (joyBtn(1) && (nMotorEncoder[motorA] < target)
    {
        motor[motorA] = 50;
    }
    else
    {
        motor[motorA] = 0;
    }
}
