Is there a problem with this code. I keep receiving errors when I compile this. I am new at programming, so thanks for all the help.

[edit: In the real code, the brackets are spaced out. The code is not all on the left side.]

#2

Yes, a couple

This


if(SensorValue(sensorTouch == 0)

should be this


if(SensorValue[sensorTouch] == 0 )

SensorTouch I assume is already defined

There is also a missing “;” after one of your wait1Msec calls, but you can find that yourself :slight_smile:

Use

[CODE]
tags (the # in the toolbar) to have your code formatted when posting.

Thank you!

Another question. How do I know which channels are which on the joy stick.
Also, can someone post a simple 2 motor Tank Drive program I could download and look over.

Never mind the Joystick Channels question. I just got my answer here:

From C:\Program Files\Robomatter Inc\ROBOTC Development Environment\Sample Programs\VEX2\Remote Control\Dual Joystick Control.c:

  while(1 == 1)
  {
    motor[leftMotor]  = vexRT[Ch3];   // Left Joystick Y value
    motor[rightMotor] = vexRT[Ch2];   // Right Joystick Y value
  }

If you wanted to try Arcade (One stick control), then:
C:\Program Files\Robomatter Inc\ROBOTC Development Environment\Sample Programs\VEX2\Remote Control\Single Joystick Control.c:

  while(1 == 1)
  {
    motor[leftMotor]  = (vexRT[Ch2] + vexRT[Ch1])/2;  // (y + x)/2
    motor[rightMotor] = (vexRT[Ch2] - vexRT[Ch1])/2;  // (y - x)/2
  }

The channels are printed on the joystick itself.
