Object Barriers in AS3? - actionscript-3

Question

I am a beginner at coding but I am trying to make a flash rpg type game. I have a barrier around my game and a walking person (manmc). I have been watching videos/reading articles on how to make object barriers but I can not seem to get the coding right without getting errors. I am trying to get my character to stop when he hits a tree. The tree is coded as (treer1_MC). I only tried to code it on the down press but it does nothing and it causes the character to not be able to walk back up.
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
import flash.display.MovieClip;
import flash.events.Event;
import flash.display.Stage;
manmc.gotoAndStop ("Stand Front Frame");
var rightPressed:Boolean = new Boolean(false);
var leftPressed:Boolean = new Boolean(false);
var upPressed:Boolean = new Boolean(false);
var downPressed:Boolean = new Boolean(false);
var manSpeed:Number = 3;
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler);
stage.addEventListener(KeyboardEvent.KEY_UP, keyUpHandler);
stage.addEventListener(Event.ENTER_FRAME, gameLoop);
function keyDownHandler (keyEvent:KeyboardEvent):void
{
if(keyEvent.keyCode == Keyboard.RIGHT)
{
rightPressed = true;
}
else if(keyEvent.keyCode == Keyboard.LEFT)
{
leftPressed = true;
}
else if(keyEvent.keyCode == Keyboard.UP)
{
upPressed = true;
}
else if(keyEvent.keyCode == Keyboard.DOWN)
{
downPressed = true;
}
}
function keyUpHandler (keyEvent:KeyboardEvent):void
{
if(keyEvent.keyCode == Keyboard.RIGHT)
{
rightPressed = false;
manmc.gotoAndStop("Stand Right Frame");
}
else if(keyEvent.keyCode == Keyboard.LEFT)
{
leftPressed = false;
manmc.gotoAndStop("Stand Left Frame");
}
else if(keyEvent.keyCode == Keyboard.UP)
{
upPressed = false;
manmc.gotoAndStop("Stand Back Frame");
}
else if(keyEvent.keyCode == Keyboard.DOWN)
{
downPressed = false;
manmc.gotoAndStop("Stand Front Frame");
}
}
function gameLoop(loopEvent:Event):void
{
if(rightPressed)
{
if(manmc.x < 1050)
{
manmc.x += manSpeed;
}
manmc.gotoAndStop("Walk Right Frame");
}
else if(leftPressed)
{
if (manmc.x > 145)
{
manmc.x -= manSpeed;
}
manmc.gotoAndStop("Walk Left Frame");
}
else if(downPressed)
{
if(manmc.y < 780)
{
manmc.y += manSpeed;
}
manmc.gotoAndStop("Walk Front Frame");
}
if (manmc.hitTest(treer1_MC))
{
trace("leftHit");
manmc._x += 3;
}
else if(upPressed)
{
if(manmc.y > 145)
{
manmc.y -= manSpeed;
}
manmc.gotoAndStop("Walk Back Frame");
}
}
This is the coding a tutorial said to use. Any suggestions?
if (manmc.hitTest(treer1_MC))
trace("leftHit");
manmc._x += 3;

Answer 1

It is just because the declaration of the collision condition is outside of your "downPress" condition:
else if(downPressed)
{
if(manmc.y < 780)
{
manmc.y += manSpeed;
}
manmc.gotoAndStop("Walk Front Frame");
}
if (manmc.hitTest(treer1_MC))
{
trace("leftHit");
manmc._x += 3;
}
indentation problems :), the right way should be:
else if(downPressed)
{
if(manmc.y < 780)
{
manmc.y += manSpeed;
}
manmc.gotoAndStop("Walk Front Frame");
if (manmc.hitTest(treer1_MC))
{
trace("leftHit");
manmc._x += 3;
}
}
I hope it helps ;)
Edit:
manmc.hitTest(treer1_MC)
should be:
manmc.hitTestObject(treer1_MC)
Because the function: hitTest() is a AS2 function, on AS3 whe have: hitTestPoint() and hitTestObject() ;)
