Here is a Stopwatch class that does the sort of thing that Jeurgen discussed
in his message. You can instantiate as many stopwatches as you want to keep
track of the elapsed time between different events.
import josx.platform.rcx.*;
/**
* Elapsed time watch (in milliseconds) <br>
* To use - construct a new instance.
* @author Roger Glassey
* version 2
*/
public class Stopwatch{
/**
records system clock time (in milliseconds) when reset() was executed
*/
private int t0 = 0;
/**
constructor: make a new stopwatch and reset it
*/
public Stopwatch() { reset();}
/**
Reset watch to zero
*/
public void reset(){
t0 = ((int)System.currentTimeMillis());
}
/**
Return elapsed time in milliseconds
*/
public int elapsed( ){
return ((int)System.currentTimeMillis()) -t0;
}
/**
This method returns after delay milliseconds
*/
public void wait(int delay) {
reset();
while (elapsed()<delay);
}
}

| (...) Interesting, I should browse through the classes every now and then ... One thing to note is that josx.platform.rcx is not the right place for it, as it is independent of the RCX platform (maybe josx.util ?). (...) I think it would be better (...)

| I am using legjos and... having problems understanding the clock/timers. 1. Are their only one timer clock? 2. How do you acess the timers clock? What code would I use? Scott (22 years ago, 29-Aug-02, to lugnet.robotics.rcx.java)
