FIX Bug: It’s now impossible to release a ghost and grab him with another buster IN THE SAME TURN.

#2

Does this apply to EJECT as well? I.E. can you EJECT and BUST the same ghost in the same turn?

Yup, Same for EJECT/STUN as well.

#4

I’m not sure what’s wrong with my code… I checked it thoroughly but I’m pretty sure I got the ghost coordinates right, so why do my busters merely stay in place?

         } 
    }
    }`

Any help?

I didn’t test it, but it looks as if you produce too many lines of output (more than one per buster). This will result in the rest of your output for this round being interpreted as the output for the next round.

But please don’t post code here, as it is a spoiler for other players.

This is my code snippet in java to release the ghosts:

if (state == 1) { // if ghost is captured
    System.out.println("MOVE 0 0");
    System.out.println("RELEASE");
}

But the ghosts are released at the same place that they are captured.
What am I doing wrong?

#7

The moves are not immediate. “MOVE 0 0”, will initiate a move to this coordinates, but you will not be on this position until the next turn, or more, depending of the distance.

Thanks for the reply.
So how do I release the ghosts at the destination?

#9

You know your buster’s coordinates, so just test if he is at your base and then use “RELEASE”.

How would I command a specific buster to MOVE, BUST or RELEASE as there is no buster id involved in the command?
In other words, how would I know which buster will follow which command?

#11

I’m pretty sure it follows the buster id, so the first command goes to your first buster etc
