PHP keyboard input (movement)

[ShadyCoco]

Hey,

I'm using a tile based game engine writen in PHP,mysql, java (small amount) and I really want to add keyboard movement along side pressing buttons (on screen) to move.

Any ideas on what language I should use to do it?

You wanna use javascript and just capture which key is hit then run the function.

Well, daves answered it, but may I ask why are you using PHP, MySQL and Java?

[ShadyCoco]

It's a really old engine :/

Trying to bring it to the new ages :)

[Danny696]

Wouldnt it be easier to make it all in Java then?

Do you by any chance mean Javascript? Cause Java is a completely different language.

Yeah sorry haven't had much sleep :S

I', using this but it don't seem to be collecting it.

function getkey(e)
{
if (window.event)
  return window.event.keyCode;
else if (e)
  return e.which;
else
  return null;
}

function redir(key)
{
       var rkey = getkey(key);

       if(rkey == 119)
       {
               document.location.href="index.php?x=200&y=100";
       }

       if(rkey == 115)
       {
               document.location.href="index.php?x=200&y=200";
       }

       if(rkey == 97)
       {
               document.location.href="index.php?x=150&y=150";
       }

       if(rkey == 100)
       {
               document.location.href="index.php?x=250&y=150";
       }
}

Why not create a div and then move it using something like:

var speed = 4;
document.getElementById('THE_ID_OF_THE_DIV').style.top += speed;

If your using the jQuery library, you may have better luck using the jKey plugin

Then you do something like (portion taken from their samples page):

[js]

$(document).jKey('up, left, down, right, up+right, up+left, down+right, down+left', function (key) {

//Current location is y = 2 x = 2

if (key == 'up') {

player.location = 'n:3,2'; // North, y =3, x =2

} else if (key == 'down') {

player.location = 's:1,2'; // South y = 1, x = 2

} else if (key == 'left') {

player.location = 'w:2,1'; // West y = 2, x = 1

} else if (key == 'right') {

player.location = 'e:2,3'; // East y = 2, x = 3

} else if (key == 'up+right') {

player.location = 'ne:3,3'; // N'East y=3, x = 3

}

//So on and so forth.

});

[/js]

for example.

Urgh didn't see your previous code Shady, would have saved me thinking of an appropriate value for the updated location. T.T
