[appleeaters]1 goes left instead of left and down!

Hello!

If I do
$cR->move(1);

the robotslib prints out
The player moved from (97,100 ) to (96,100 ) (command: 1)
Instead of "to (96,99)"!

First I assumed a coding mistake in robotslib.php. The corresponding code passage looks like this:

case 1:
$this->player[0]--;
$this->player[1]--;
break;

If I print_r the $this->player array before break; it says

Array ( [0] => 96 [1] => 100 )

How can that be?


Thank you very much,

I've seen this error before too (causes the robots AND the player to only be able to move left/right), but couldn't find a fix for it, so I restored to the original copy of robotslib and generated a new game and the bug went away. The only thing I could come up with in my mind was that PHP crapped out for some unknown reason and couldn't write to the Y co-ordinate.

One other thing to check: when using $robots->move($move), make sure to capture the return into $game or some other variable. It may be that you're not recapturing the $game variable and that somehow, PHP is copying the old value back in to the new or something like that. But past that I have absolutely no idea. I just remember that's some of the things that ran through my mind when I ran into the problem a few days ago. Hope that helps..

Thanks for your reply.
Meanwhile I found 2 bugfixes:

1. Turn $this->player[1]--; into $this->player[1] = $this->player[1] - 1; will work.
2. Fidians (great) extended robotslib.php does not have this bug [and works even better] --> http://rumkin.com/php_contest/ Thanks Fidian!
