alright ill try some of those out not exactly sure how to do it but ill probably figure something out
Itās missing some tags, like arrays and loops. I donāt think you can solve this without checking where the elevator is and for that you need an array, datatable or sth.
Iām stuck on the first part.
When I put āLEFTā or āRIGHTā in output, I get the message "invalid input. Expected āWAIT, BLOCKā but found āLEFTā ". But if I put āWAIT, BLOCKā, I get "invalid input. Expected āWAIT, BLOCKā but found āWAIT, BLOCKā ". And if I put āWAITā or āBLOCKā the time all the clones come out, I lose. So what do you have to do to give a direction to the clones ? 
You should output either āWAITā or āBLOCKā in each turn. You do not output the same command for all turns. For example, you BLOCK the first clone to prevent future clones from moving right. Then you output WAIT for the rest of the game because all clones are moving in the correct direction.
Hi,
Can someone give me a hand with this please ?
I dont know why but, my code wont work properly. When it should āblockā it wont even if my āifā is true.
Here is my code, I know itās not clean and optimized but I think it should workā¦ I think 
class Player {
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
int nbFloors = in.nextInt(); // number of floors
int width = in.nextInt(); // width of the area
int nbRounds = in.nextInt(); // maximum number of rounds
int exitFloor = in.nextInt(); // floor on which the exit is found
int exitPos = in.nextInt(); // position of the exit on its floor
int nbTotalClones = in.nextInt(); // number of generated clones
int nbAdditionalElevators = in.nextInt(); // ignore (always zero)
int nbElevators = in.nextInt(); // number of elevators
int[] refAsc = new int[nbElevators + 1]; // an array to save the exit and elevator position
for (int i = 0; i < nbElevators; i++) {
int elevatorFloor = in.nextInt(); // floor on which this elevator is found
int elevatorPos = in.nextInt(); // position of the elevator on its floor
refAsc[elevatorFloor]=elevatorPos;
}
System.err.println(nbElevators+ "nb elev");
System.err.println(Arrays.toString(refAsc));
int deplacement = 1;
int cible = exitPos;
int distanceT0; // distance at T=0
int distanceT1; // distance after the "move"
refAsc[exitFloor]=exitPos;
// game loop
while (true) {
int cloneFloor = in.nextInt(); // floor of the leading clone
int clonePos = in.nextInt(); // position of the leading clone on its floor
String direction = in.next(); // direction of the leading clone: LEFT or RIGHT
System.err.println(cloneFloor + " clonefloor");
if (direction.contains("R")){ // give an num valeur in fonction of the direction
deplacement = 1;
} else if (direction.contains("L")){
deplacement = -1;
}
System.err.println(deplacement + " deplacement");
if (cloneFloor >=0 ){
cible = refAsc[cloneFloor];
} else {
System.out.println("WAIT");
}
distanceT0 = Math.abs(cible - clonePos);
distanceT1 = Math.abs(cible - (clonePos + deplacement));
System.err.println(cible + " cible");
System.err.println(clonePos + " position clone");
System.err.println(deplacement + " depl");
System.err.println(distanceT0 + " dist0");
System.err.println(distanceT1 + " dist1");
System.err.println(cible + " cible");
if (distanceT0 == distanceT1){
System.out.println("WAIT");
}
else if (distanceT0 < distanceT1) {
System.err.println(" if of block");
System.out.println("BLOCK");
} else {
System.err.println(" le w8");
System.out.println("WAIT");
}
// Write an action using System.out.println()
// To debug: System.err.println("Debug messages...");
System.out.println("WAIT"); // action: WAIT or BLOCK
}
}
}
The problem is at this stage:
else if (distanceT0 < distanceT1) {
System.err.println(" if of block");
System.out.println(āBLOCKā);
It work on the first lvl but it goes wrong at the third lvl
Respectfully Einsenhorm,
It would help to debug if you read your code and walk through it manually 
You should notice that you have Sytem.out.println in a few places: within the first if-block, within the second if-block, and outside the said if-blocks. In a single while-loop (i.e. a single turn), youāre supposed to output once only. But your code outputs more than one command in a single turn, so, the game engine treats them as commands for several turns, and the logic as a result goes out of sync with your original intention.
Thanks, I will change that and try with only one out.println.
UPDATE :
Well Iāve change the out.println into only one but the probleme is still the same.
error exits :
1 clonefloor
1 deplacement
1 cible
7 position clone
1 depl
6 distanceT0
7 distanceT1
1 cible
le w8
Standard exit:
WAIT
Informations :
You do nothing.
My if condition to give a āBLOCKā is :
else if (distanceT0 < distanceT1) {
System.err.println(" if of block");
System.out.println(āBLOCKā);
So normaly it should be true, as you can see above : 6 distanceT0 and 7 distanceT1
6 < 7 = true normaly but, in this case it seem not . . .
You may PM me your code so that I can check and discuss with you further in private.
Quite sure I understand the game but i checked with the debug options and it is not synchronised the values that are taken from input with the game.
I got the āWarning: your code did not read all available input before printing an instruction, your outputs will not be synchronized with the gameās turns and unexpected behaviour may occur.ā but i do not understand. I use the variables I need and the logic is quite simple.
Any idea of how to synchonised and avoid the warning?
The message means your code has either output too many lines or skipped output before reading the new roundās inputs. You are suggested to use the error stream to keep track of when you read new inputs and when you write outputs.

It seems Iām not allowed to send you a PM "^^.
Iāve sent you a PM. You may continue from there 
Continuing the discussion from Don't Panic - Episode 1 - Puzzle discussion:
Already solved it. Finally, it was too may output lines.
I see strange behaviour: in IDE all tests are passed but in submitting validation step last test - āSpaced elevators, few roundsā - is failed, and when I watch the animation of failing test I notice that leading clone does reach elevator at (last-1) floor but does not appear on last floor with exit - instead it becomes blocked.
Could you share your replay link here?
hi good morning, im hving issues with the code, i got the first 5th rounds but th 6th and the7th shows this erros message āMax rounds count reachedā and i used this code
int tope = width-1;
int cero = width - tope;
if (clonePos < tope && clonePos >= cero )
{
Console.WriteLine("WAIT");
}
else
{
Console.WriteLine("BLOCK");
}
can anyone help me :
Could you please specify which test case you are talking about, and share a link to the replay?
the las 2 of them.
few rounds
spaced elevators few rounds

Sorry, I was confused because you talked about āroundsā not ācasesā.
Could you please share the replay links?
