# Power Of Thor - Episode 1 - Puzzle discussion

#656

Coordinates 0,0 are in the top-left corner, so going North will reduce your Y-coordinate by 1. This is standard in computer graphics.

#657

Same in JS

#658

I wish it would specify in description that Thorâs coordinateâs arenât updated automatically.
I thought âstarting coordinatesâ were for each turn of the game

#660

maan, first I didnât update thors position and then I set thors position = initialPosition before the initialPosition is initialized xP

#661

same problem here. iâm trying to solve it on python

#662

Hey, i solved it. You have to update thorâs coordinates in every move. Thorâs coordinates in the input doesnât change, it only gives you the first coordinates of Thor.

#663

was getting frustrated so i copy pasted the solution to make sure it was possible. still doesnât reach his goal on the last two testsâŚusing swift.

#664

Wrote a correct code, didnât work. Copy-pasted the ââsolutionââ offered - that doesnât work either.

#665

The given solution works for me. Seems you made a mistake while copy pasting. Does the pseudo-code and the solution help you understand whatâs wrong in your code?

#666

Same to java, during testing all tests passed, and in submitting the last one is not working https://gyazo.com/bbba7537617c392f11ec54ff0d677d6b

seems youâre not handling correctly the direction South West. Check the replay.

I have no idea what is this error( error: bad operand types for binary operator â&&â if((lightX > initialTX && lightY = initialY))

This is my code:

â==â != â=â

Check your expressions. (Assignment vs Comparison)
x = 1 is an assignment,
x == 1 a comparison

#671

I have absolutely no clue on how to do the whole angles bs, I got the straight line and up testcases figured out, but I have no clue how to do the angle testcases

#672

Try this:

Create an empty string.
If the y-coordinate is not the same as the target y-coordinate, make the string N or S, as appropriate.
If the x-coordinate is not the same as the target, add E or W to the string.
Output the string.
Donât forget to update your position.

#674

Iâm a begginier.
In python, I dont undertsand while 1 :
Why 1 ? whatâs this condition ? I dont understant why it is not an infinite loop ? because 1 is always true ?

#675

Yes it is a infinite loop. Dont need a exit for this program.

#676

In the if statement : You are writing initialY instead of initialTY!

#677

I dont understand whats going wrong with my code.
It seems only once the loop is getting iterated as only one character is getting printed. Please help me out.

``````import java.util.*;
class Player {
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
int lightX = in.nextInt(); // the X position of the light of power
int lightY = in.nextInt(); // the Y position of the light of power
int initialTX = in.nextInt(); // Thor's starting X position
int initialTY = in.nextInt(); // Thor's starting Y position
while (true)
{
int remainingTurns = in.nextInt();
String dirX="";
String dirY="";
if(initialTY<lightY)
{
dirY= "S";
initialTY++;
}
else if(initialTY>lightY)
{
dirY="N";
initialTY--;

if(initialTX<lightX)
{

#678

Check your IFs, you mixed X and Y somewhereâŚ

And try println instead of printâŚ

Every now and then use System.err.println(); for debug, sometimes it helps
