Question

I been trying to make a PHP path finder from examples in other languages and tweaked it for my game’s need but its not returning any values.

I should note – I get no errors in my error log file either so I’m guessing its a logic mistake?

Hope some one can spot it cos i cannot see the mistake =/

Just took a really short look, but:

function findpath($sx, $sy, $sdata) {
    if( in_array($sx, $sdata) && in_array($sy, $sdata($sx) ) ){
        ...
    }
}

$sdata = array(
           "13" => ...,               
           "14" => ...,    
           "15" => ...
);

$astar = findpath(13,15,$sdata);

in_array checks the array values, not the keys… as such, your whole function doesn’t even do anything. Use array_key_exists for this.
