does anyone know how to reduce the amount of string used to move Thor?

i.e.

While true
initial_tx != light_x
destinationX = light_x

initial_ty != light_y
destinationY = light_y

is this possible? i get a syntax error when trying to automate his movements.

#1102

Could you please explain a bit more about what you’re trying to do, like, how you intend to move Thor? I’m afraid I can’t understand your message.

If you want to reduce the number of turns to move Thor, you should move Thor in a diagonal direction as many times as needed. For example, if you move Thor N and then E, that’ll take two turns, while it takes just one turn to move Thor NE directly.

#1103

it’s more, i’m looking to make the code smaller? like, after i figured out the X Y axis idea, to go N +/- 1 depending on initial_ty. I wanted to see if i can condense the script for the code? is there any way instead of doing +/- = 1 on the X/Y axis, without having to utilize numbers? or is the most efficient way of reaching the destination just +/- 1?

#1104

Once you’ve got the initial data, you can already plan ahead what moves to do without referring to subsequent data. Maybe that’ll help you condense the script in some way? But even then, you still have to “utilize numbers” for at least one turn.

#1105

right. i feel like doing if thor_x > light_x:
direction_x = “W”
thor_x -= 1

isn’t good enough in a sense? to have one string per direction feels like it needs to be made more efficient so i’m trying to figure out how i can create a string that makes Thor move without as much lines of code.

#1106

I genuinely feel too dumb right now. Cannot get the second challenge of getting Thor to do down. Any pointers? Trying to learn python

If you look to the left of the puzzle statement on https://www.codingame.com/ide/puzzle/power-of-thor-episode-1, you’ll find a HINTS button. Those hints may help you get started.

You’ll also find some Python learning resources here.

I can’t solve the whole thing but one!!!

like I can only solve one!!!

Also note that your code should be general enough to solve all the test cases.

Is this a question or a solution?

#1113

a question for a solution

#1114

I’ll wait even if it costs my life!

#1115

can I be your friend?

#1116

Please stop spamming the forum. Study the error messages in the console after you run your code, and then try to fix the bugs accordingly.

#1117

i wrote this code but it is not working in c and i am only a 9th grader so please teach this to me i dont understand nothing
if(TY< LY) {printf(“E”);}
else if(LX < TX) {printf(“N”);}
else if(TY < LY) {printf(“S”);}
else {printf(“SE”);}
please tell me what is wrong
btw i wrote TY, LY, LX and LX because i changed the variables

#1118

You have to print a newline every time after you output the direction for a round.

Also, your code has to update the positions of Thor if it does not do so at the moment.

If you look to the left of the puzzle statement on https://www.codingame.com/ide/puzzle/power-of-thor-episode-1, you’ll find a HINTS button. More hints are available there.

I have a question:

Why does the following code fail ?

while True:
    remaining_turns = int(input())  # The remaining amount of turns Thor can move. Do not remove this line.

    # Write an action using print
    # To debug: print("Debug messages...", file=sys.stderr, flush=True)
    dir = ""
    if light_y != initial_ty :
        if light_y-initial_ty > 0 :
            dir = dir + "S"
        elif  light_y-initial_ty < 0 :
            dir = dir + "N"
    else: 
        dir=""
    if light_x != initial_tx :
        if light_x-initial_tx > 0 :
            dir = dir + "E"
        elif light_x-initial_tx < 0 :
            dir = dir + "W"
    # A single line providing the move to be made: N NE E SE S SW W or NW
    print(dir)

This fails for an angle but by my understanding when the x or y coordinate becomes same thor should move in one direction like E or N and not SW or SE .

Sorry if this is stupid

#1120

You don’t seem to update Thor’s coordinates.
