First off,
i am
a noob to JavaScript but am willing to learn. :)
I found
a simple JavaScript moment engine created by another member on this site. Using that
i made it so my character can walk around within
a rectangle/square shaped room.
I want to make it so the character can walk through
a "doorway" within
a wall to the next room. Either that or make it so if the character moves over
a certain image within the room it will take the player to another webpage in which the character "spawns" into the room and so on and so fourth.
Here is
a link to what
i have made so far as to get an idea.

Any help would be much appreciated. Here is the javascript code
for the character movement and boundaries.
<script type='text/javascript'>
// movement vars
var xpos = 100;
var ypos = 100;
var xspeed = 1;
var yspeed = 0;
var maxSpeed = 5;
// boundary
var minx = 37;
var miny = 41;
var maxx = 187; // 10 pixels
for character's width
var maxy = 178; // 10 pixels
for character's width
// controller vars
var upPressed = 0;
var downPressed = 0;
var leftPressed = 0;
var rightPressed = 0;
function slowDownX()
{
if (xspeed > 0)
xspeed = xspeed - 1;
if (xspeed < 0)
xspeed = xspeed + 1;
}
function slowDownY()
{
if (yspeed > 0)
yspeed = yspeed - 1;
if (yspeed < 0)
yspeed = yspeed + 1;
}
function gameLoop()
{
// change position based on speed
xpos = Math.min(Math.max(xpos + xspeed,minx),maxx);
ypos = Math.min(Math.max(ypos + yspeed,miny),maxy);
// or, without boundaries:
// xpos = xpos + xspeed;
// ypos = ypos + yspeed;
// change actual position
document.getElementById('character').style.left = xpos;
document.getElementById('character').style.top = ypos;
// change speed based on keyboard events
if (upPressed == 1)
yspeed = Math.max(yspeed - 1,-1*maxSpeed);
if (downPressed == 1)
yspeed = Math.min(yspeed + 1,1*maxSpeed)
if (rightPressed == 1)
xspeed = Math.min(xspeed + 1,1*maxSpeed);
if (leftPressed == 1)
xspeed = Math.max(xspeed - 1,-1*maxSpeed);
// deceleration
if (upPressed == 0 && downPressed == 0)
slowDownY();
if (leftPressed == 0 && rightPressed == 0)
slowDownX();
// loop
setTimeout("gameLoop()",10);
}
function keyDown(e)
{
var code = e.keyCode ? e.keyCode : e.which;
if (code == 38)
upPressed = 1;
if (code == 40)
downPressed = 1;
if (code == 37)
leftPressed = 1;
if (code == 39)
rightPressed = 1;
}
function keyUp(e)
{
var code = e.keyCode ? e.keyCode : e.which;
if (code == 38)
upPressed = 0;
if (code == 40)
downPressed = 0;
if (code == 37)
leftPressed = 0;
if (code == 39)
rightPressed = 0;
}
</script>
here is the HTML code to follow
<!-- The Level -->
<img src="room1.png" />
<!-- The Character -->
<img id='character' src='../texture packs/characters/snazgel.png' style='position:absolute;left:100;top:100;height:40;width:26;'/>
