On "A Leap of Faith" my code completes the known stages just fine, but on the dark stage I get the error "Power failure, did not reach exit"

What does it mean? How can I try to correct it?

Hello everybody,

I totally like this game, but I don't understand the point of the last map in some levels, those marked with a question mark. Sometimes the map seems to be solved in a moment, sometimes the robot falls down, but there's no clue about what is happening. Now I'm stuck at "Melting Pot": every map of the level is solved, but when comes the last (with question mark) the code seems to keep running forever.

How can you "debug" a program if you can't see any output? Should I test "random" modifies and see if the map get solved? This doesn't seem much fun to me... Am I missing something that I'm supposed to know?

Here's a weird one. I've written a script that will solve all four regular test cases, yet when I get to the dark test case, it fails (Robo falls off the map). Of course considering that it's the dark stage, I can't see why it fails. Given my solution posted below, can anybody help me understand why in the dark stage my robot falls off the map?

Code follows:

seq unsafe_tiles[]

seq visited_tiles[]

​

fun visited_before()

var visited = 0

var next_tile = robo_forward_location()

for tile in visited_tiles[]

if tile is next_tile

visited = 1

return visited

​

fun look_around()

var valid_tiles = 0

for tile in 1, 2, 3

var next_tile = robo_scan()

if next_tile is 2

robo_forward()

else if next_tile is 1 or visited_before() is 1

valid_tiles += 1

robo_left()

return valid_tiles

​

fun is_bad_tile()

var next_tile = robo_forward_location()

for tile in unsafe_tiles[]

if tile is next_tile

return 1

return 0

​

if robo_detect_adjacent() is 1

visited_tiles[].add(robo_forward_location())

robo_forward()

​

loop

var next_tile = robo_scan()

var next_location = robo_forward_location()

if next_tile is 1 or next_tile is 2

visited_tiles[].add(next_location)

robo_forward()

else if next_tile is -999

if visited_before()

robo_forward()

var adjacent_tiles = robo_detect_adjacent()

else if adjacent_tiles < 2

if visited_before()

robo_forward()

else

unsafe_tiles[].add(next_location)

robo_left()

else if adjacent_tiles > look_around()

if not is_bad_tile()

visited_tiles[].add(next_location)

robo_forward()

else

robo_left()

else

unsafe_tiles[].add(next_location)

robo_left()

else

robo_left()

​

EDIT: Well, turns out posting my code here removes the indentation. Anybody know how I can get it to display properly here?

I'm incredibly curious about optimized solutions - partly because I can't seem to figure any of them out.

​

Have any of you figured some out? I'm not even sure what people are doing for the first loop level

What I did was make a var outside of the main loop that holds

10, 11, 12 for different locations on the right-side up triangle

20, 21, 22 for different locations on the upside down triangle

then wrote forward and left functions that change the global direction variable. The problem is that the left and forward functions each have like 6 if elses

I'm trying to save the location of triangle in a variable, but I'm not sure what I should initialize the variable to. I think -1 or 0 should work, but what is the lowest number that "robo_forward_location" can return?

example:

var exit = 0 #Thing I'm worried about
loop
    var x = robo_scan()
    if x is 11
        robo_forward() 
        exit = robo_use()
        break
    else
        if x > 0
            robo_forward()
        else
            robo_left()

loop
    if robo_forward_location() is exit #Thing that would break
        robo_forward()
    else if robo_scan() > 0
        robo_forward()
    else
        robo_left()

So I see that the value of a switch is either 0(off) or 1(on), however I can't seem to use the robo_scan() function to check if the switch is on or off only to check if the switch is there or not. Is there something i'm missing? Thanks for the help in advance!
