Since there doesn't seem to be alot of activity in the java group
(particularly for beginners), I'm posting my java version of the DiscShooter
program from the Advanced Builders Set. Let's see some other examples out
there!

import josx.platform.rcx.*;
public class DiscShooter implements SensorConstants {
public DiscShooter() {
Sensor.S2.setTypeAndMode(SENSOR_TYPE_LIGHT ,SENSOR_MODE_PCT);
Sensor.S2.activate();
Sensor.S3.setTypeAndMode(SENSOR_TYPE_TOUCH,SENSOR_MODE_BOOL);
Motor.A.setPower(7);
Motor.C.setPower(7);
Motor.B.setPower(7);
}
public static void main(String[] args) {
DiscShooter bot = new DiscShooter();
Motor.C.forward();
Motor.B.backward();
for (int numDiscs = 1; numDiscs < 7; numDiscs++) {
while (bot.isBright() != true); // wait for the disc to get past light
sensor
try {Thread.sleep(500);} catch (Exception e) {}
if (numDiscs % 2 == 0 ) {
Motor.A.backward();
} else {
Motor.A.forward();
}
for (int turnGun = 1; turnGun < 6; turnGun++) {
while (Sensor.S3.readBooleanValue() == true);
while (Sensor.S3.readBooleanValue() == false);
}
Motor.A.stop();
}
try {Thread.sleep(2000);} catch (Exception e) {}
Motor.B.stop();
Motor.C.stop();
}
public boolean isBright() {
return (Sensor.S2.readValue() > 30);
}
}
p.s. kudos to Brian Bagnall on his excellent book "Core Lego Mindstorms
Programming". It has really changed my interest from NQC to java.

| I think it would be a great idea to have a fixed robot design and a specified behaviour for that robot and then for people to write various applications to make it work. Is this disc shooter design available somewhere? (...) SNip to keep lugnet (...) (22 years ago, 10-Jul-02, to lugnet.robotics.rcx.java)
