i posted this in the gaming forum but im sure some of you AS3 pplz who don’t do gaming would like to know about it.

hey game pplz i made a nice little function that lets you take a character (mc) and a stage (area) and if the character moves to the edge it will scroll the area instead of moving the mc
Code:
//BY: Donovan Hubbard 2007
//Action Script 3, Move to Pan
function moveToPan(mc:MovieClip, area:MovieClip, speedX:Number, speedY:Number, bounds:Number) {
var stgLeft:Number = bounds;
var stgRight:Number = stage.stageWidth - bounds;
var stgUp:Number = bounds;
var stgDown:Number = stage.stageHeight - bounds;
var atLeft:Boolean;
var atRight:Boolean;
var atUp:Boolean;
var atDown:Boolean;
if (Math.abs(area.x - stage.stageWidth) >= area.width-20) {
mc.x -= 1;
area.x += 1;
return;
}
if (area.x > -20) {
mc.x += 1;
area.x -= 1;
return;
}
if (Math.abs(area.y - stage.stageHeight) >= area.height-20) {
mc.y -= 1;
area.y += 1;
return;
}
if (area.y > -20) {
mc.y += 1;
area.y -= 1;
return;
}
if ((mc.x < stgLeft)&&(speedX<0)) {
area.x -= speedX;
atLeft = true;
} else if ((speedX>0)&&(!atRight)) {
mc.x += speedX;
atLeft = false;
}
if ((mc.x > stgRight)&&(speedX>0)) {
area.x -= speedX;
atRight = true;
mc.x -= speedX;
} else if ((speedX<0)&&(!atLeft)) {
mc.x += speedX;
atRight = false;
}
if ((mc.y > stgDown)&&(speedY>0)) {
area.y -= speedY;
atDown = true;
} else if ((speedY<0)&&(!atUp)) {
mc.y += speedY;
atDown = false;
}
if ((mc.y < stgUp)&&(speedY<0)) {
area.y -= speedY;
atUp = true;
mc.y -= speedY;
} else if ((speedY>0)&&(!atDown)) {
mc.y += speedY;
atUp = false;
}
}
hope this aids some of you in your game developing :p:
