bitmap hit testing error - actionscript-3

Question

I'm trying to get my character to bounce back when it hits an object in order to not allow it to touch the objects. My problem is when its touching 2 objects, it gets stuck and moves backwards because of my else statement. Is there any way I can change my code to not allow my character to touch the objects in the first place.
My code:
o1 is the instance name of the objects all contained in a movie clip and p1 is my charcter.
import flash.events.Event;
var upKeyDown:Boolean = false;
var rightKeyDown:Boolean = false;
var downKeyDown:Boolean = false;
var leftKeyDown:Boolean = false;
var hit:Boolean = false;
p1.addEventListener(Event.ENTER_FRAME, moveChar);
stage.addEventListener(KeyboardEvent.KEY_DOWN, checkKeysDown);
stage.addEventListener(KeyboardEvent.KEY_UP, checkKeysUp);
var redRect:Rectangle = o1.getBounds(this);
var redClipBmpData = new BitmapData(redRect.width, redRect.height, true, 0);
redClipBmpData.draw(o1);
var blueRect:Rectangle = p1.getBounds(this);
var blueClipBmpData = new BitmapData(blueRect.width, blueRect.height, true, 0);
blueClipBmpData.draw(p1);
addEventListener(Event.ENTER_FRAME, enterFrame);
function enterFrame(e:Event):void
{
if(redClipBmpData.hitTest(new Point(o1.x, o1.y),
255,
blueClipBmpData,
new Point(p1.x, p1.y),
255
))
{
o1.filters = [new GlowFilter()];
hit = true;
}
else
{
o1.filters = [];
hit = false;
}
}
function moveChar(event:Event):void{
if(downKeyDown && !upKeyDown && !rightKeyDown && !leftKeyDown)
{
p1.gotoAndStop("walk_down");
if(!hit)
p1.y += 5;
else
p1.y -= 10;
}
if(upKeyDown && !downKeyDown && !rightKeyDown && !leftKeyDown)
{
p1.gotoAndStop("walk_up");
if(!hit)
p1.y -= 5;
else
p1.y += 10;
}
if(rightKeyDown && !upKeyDown && !downKeyDown && !leftKeyDown)
{
p1.gotoAndStop("walk_right");
if(!hit)
p1.x += 5;
else
p1.x -= 10;
}
if(leftKeyDown && !upKeyDown && !rightKeyDown && !downKeyDown)
{
p1.gotoAndStop("walk_left");
if(!hit)
p1.x -= 5;
else
p1.x += 10;
}
}
function checkKeysDown(event:KeyboardEvent):void{
if(event.keyCode == 87){
upKeyDown = true;
}
if(event.keyCode == 68){
rightKeyDown = true;
}
if(event.keyCode == 83){
downKeyDown = true;
}
if(event.keyCode == 65){
leftKeyDown = true;
}
}
function checkKeysUp(event:KeyboardEvent):void{
if(event.keyCode == 87){
upKeyDown = false;
p1.gotoAndStop("still_up");
}
if(event.keyCode == 68){
rightKeyDown = false;
p1.gotoAndStop("still_right");
}
if(event.keyCode == 65){
leftKeyDown = false;
p1.gotoAndStop("still_left");
}
if(event.keyCode == 83){
downKeyDown = false;
p1.gotoAndStop("still_down");
}
}
Thanks in advance
EDIT:
I changed it to what you said , but now my character doesn't want to move at all :<

Is this what you meant ?

Answer 1

I think what you will want to do is do a hittest based on the anticipated locations of the objects. In order to do that, though, you would want assign speed values, instead of moving the objects on moveChar().
private var redSpeed:Point = new Point();
//in moveChat:
if(downKeyDown && !upKeyDown && !rightKeyDown && !leftKeyDown)
{
p1.gotoAndStop("walk_down");
if(!hit)
redSpeed.y = 5;
else
redSpeed.y = 0;
}
// in enterFrame
if(redClipBmpData.hitTest(new Point(o1.x + redSpeed.x, o1.y + redSpeed.y),
255,
blueClipBmpData,
new Point(p1.x, p1.y),
255)) {.....
Then you can just move the object by its speed.
