Sidescrolling Platformer Help

[TazarTheYoot]

I've got the makings of quite a nice platformer, but I can't seem to make it sidescroll. I've got all the player movements in place and everything, I just want to know how to make the screen scroll when the player gets within a certain distance of the side of the screen.

Kind of like this:

if((character._x < 100 && dir == -1) || (character._x > Stage.width - 100 && dir == 1)) {
level._x -= speed * dir;
} else {
character._x += speed * dir;
}

If the character is by the left side and going left, or by the right side and going right, then move the level. Otherwise, move the character. In the first part, you'll have to put other things you want to move (i.e. enemies or whatnot).

onEnterFrame=function(){
if(_root.guy._x>500){
_root._x++;
}
}

if the guy's further along than 500, move the stage to the right. You wouldn't think _root._x was an actual thing but it is.

Hmm, neither of those work.

Use this http://www.oreillynet.com/pub/a/javascri pt/2004/08/17/flashhacks.html?page=2
It's a cool AS2 camera that shows everything through a rectangle or other shape.

use a while loop it works better and can handle any speed

while(_x>400){
_root.ground._x--
_root.player._x--
}
while(_x<100){
_root.ground._x++
_root.player._x++
}

that is extremely simplified but uses no variables so i like that better.

It works perfectly for me, so you just don't know how to implement it.
