This is a lovely little game where you have to "hack" the script that runs the page to get to the exit.

Really nicely done.

Nah, got a bit bored at the start of chapter 2, but I expect I'll go back to it.

I'm stuck on the river with the raft.

ZOMG Spoiler! Click here to view!
I am trying to use player.getY(), but it says player is not defined. I used player.getX() on the coloured barrier level, so am a little confused.

It's not defined for you like it is on some other levels. Just throw in a
Code:
var player = map.getPlayer();
at the start of your code.

Well, I've got to level 15, which is causing some headscratching.

Be interested to know how people solved the last of the robot mazes.

ZOMG Spoiler! Click here to view!
I just went for a cheap trick of having 4 squares I could stand on which moved it in a certain direction. Hardly advanced AI like they spoke of it the comment.

That's exactly what I did.
ZOMG Spoiler! Click here to view!
Bound up four squares and used them like a joypad :)


There's a big clue in the level name for 15.

Yeah, I got it eventually

Bear in mind that doing such a thing isn't even possible in c#. Tried chucking null at it, and blank before posting that. Currently being thwarted by completely useless errors in level 17. I can think of numerous ways of doing it, but can't get any of them to work and the error messages are useless. Similarly my first solution to the maze did require a simple searching AI, but no longer have the javascript knowhow to even create an array

Yeah, the error handling makes life complicated.

Code:
var myArray = ['foo', 'bar'];
;)

Yeah, somewhat tedious if you have a 2D array of visited nodes the size of the maze.

Onto the jumping one now.

I'm stuck on level 9. I don't know javascript so I don't know how to do what I want to do.


ZOMG Spoiler! Click here to view!
I want to bind a callback to the phone so that it moves the raft up one place each time I press the button, or to make it switch it's behaviour method to move towards the exit. But I don't know how to reference the raft object?!

findNearest('raft') (or possibly 'dynamic', looking at the api section?) doesn't seem to be defined on the player or the map.



edit: Also

ZOMG Spoiler! Click here to view!
var player = map.getPlayer();
is already in the scope for the editable bit of level 9? Have they changed it since?

You don't need to reference the raft object.

ZOMG Spoiler! Click here to view!
There's a variable called raftDirection that tells the raft which direction to move...

I just saw that. I AM A RETARD. I just read it's behaviour as always me.move() and assumed that had it moving towards the player, rather than always moving in a certain direction.

and for level 10: Javascript advice: Why doesn't this work?

ZOMG Spoiler! Click here to view!
Why can't I just change this:

map.defineObject('attackDrone', {
'type': 'dynamic',
'symbol': 'd',
'color': 'red',
'onCollision': function (player) {
player.killedBy('an attack drone');
},
'behavior': function (me) {
moveToward(me, 'player');
}
});

into this:

'behavior': function (me) {
me.onCollision = function(player){};
me['onCollision'] = function(player){};

}

Shouldn't that work? I just want to nop out their lethal attack, basically...
Note: I solved it another way, but I want to know what I'm doing wrong here. The API info seems to suggest what I did is valid?



Anyway, no spoilers for this:

Code:
        'behavior': function (me) {
            me.lol_state = 0
           
            if (me.lol_state == 0)
            {
               me.move('down')
                me.lol_state = 1
            }
         else
            {
               me.move('right')
            }
   
        }

or:

        'behavior': function (me) {
            me.behavior.lol_state = 0
           
            if (me.behavior.lol_state == 0)
            {
               me.move('down')
                me.behavior.lol_state = 1
            }
         else
            {
               me.move('right')
            }
   
        }



This doesn't work, but the few things I know about javascript (e.g. this page) would suggest it should. Infact the second one doesn't move the robot at all for some reason?

So the language we're using here either a) isn't simply javascript pushed through an eval() function or b) they pass in a copy of the robot into the behaviour function each time or c) probably a combo of both

The dirty cheats.

This game is phenomenally ace.

I think I didn't get into the spirit of the thing for the robot...

ZOMG Spoiler! Click here to view!
me.move(dir);
}
});

var dir = 'left';

a = function () {
if (dir == 'left')
dir = 'up';
else if (dir == 'up')
dir = 'right';
else if (dir == 'right')
dir = 'down';
else if (dir == 'down')
dir = 'left';
}

player.setPhoneCallback(a);

map.defineObject('dave', { 'behavior': function(me) {

--

If the black space lets me put in blank lines, by god that's what I'll do!


I don't have time to figure out the syntax 16 right now but it's looking like:
ZOMG Spoiler! Click here to view!
get list of adjacent cells. iterate: check type of item in cell, if trap, get canvas and draw X on cell.

all traps are now visible.


This is so much better than god damned Carnage Heart it's unreal.

I had a similar idea, although it involved moving the teleporters. Won't work - all traps are visible - they have a different symbol. Just some teleporters teleport you onto them. Obvious if you actually follow the code through too.

I actually lucked through that one when trying something else :)

I just did a search for two specific teleporters, one by the player, one by the exit, and linked the player one to the exit one. Before that I tried creating one by the player, but it threw out all kinds of strange error messages.
Neither me nor my boss particularly understood what the comment hint was about, but both came up with broadly similar solutions

If you're going to expect me to look at what's on the screen before I fumble up a solution to it, we're going to have some serious problems.

Edit - Woo, I'm a winner!

Is there any way to start from a certain level? When I unrecoverably deleted all my code with a single keystroke on level 14 or whatever I ragequit. But not I want to continue on, and I don't feel like doing 1-14 again.

Gwt the computer on the firt level, then go to the menu in the bottom right

I ws forever hitting Ctrl W to get rid of the API help...
I'd provide code for you, but I doubt you mean 1-14

Aha! Just what I wanted, although I was playing this on a different computer (at work). I got to the robot maze and was in the middle of doing that -- I think it was level 13 or 14 or something? When I re-do it I'll use MrD's cheaty method, as that's similar to what I was trying to do before but couldn't do the javascript gymnastics. (For the maze I was originally working on a proper path finding thing before I DELETED IT ALL :'()

It would be good if you could easily skip levels without a save game. I find myself on different computers a lot and would like to have another crack at the complicated robot maze ones.

ZOMG Spoiler! Click here to view!
I had a lame idea for a solution which would assign every cell a value based on its distance from the exit, and the robot would pick a random direction from the list of available cells with the lowest value, if the robot was surrounded by cells that were higher in value than the cell it currently occupied, it would set the value of the cell it currently occupied to a high value first before leaping off it to make sure it never visited it again. Crappy pathfinding, but I wanted to see if it made sense.

YUP. Though I knew about a star already, my implementation would have been a lousy bus-ride-home-back-of-napkin version without any of the list maintaining. (It's all the same stuff, so anything I don't write explicitly would be implicit.)
