hi friends,

i have a problem with this code. when i run this code, i want that the arrow should not accross the wall movieclip but it is accrossing the wall.

So if anyone have some idea about what we can do for to get the desired result.

thaks



my FLA file code:

var myclass:moveArr ay = new moveArray(arrow _mc);


As files code:

class moveArray extends MovieClip {
var targetMc:MovieC lip;
var mc:MovieClip;
var wall:MovieClip;
//var myListener:addE ventListener;
public function moveArray(targe tMc:MovieClip) {
//trace(targetMc) ;
this.targetMc = targetMc;
checkPosition(t argetMc);
updatePosition( targetMc);
}
//-------------------------------------------------------------------
public function updatePosition( mc:MovieClip) {
var myListener:Obje ct = new Object();
myListener.onKe yDown = function() {
if (Key.isDown(Key .RIGHT)) {
//trace("right key is pressed");
//trace(mc);
mc._rotation = 90;
mc._x += 25;
}
if (Key.isDown(Key .LEFT)) {
//trace("left key is pressed");
mc._rotation = -90;
mc._x -= 25;
}
if (Key.isDown(Key .UP)) {
//trace("up key is pressed");
mc._rotation = 360;
mc._y -= 25;
}
if (Key.isDown(Key .DOWN)) {
//trace("down key is pressed");
mc._rotation = 180;
mc._y += 25;
}
};
Key.addListener (myListener);
}
//------------------------------------------------------------
public function checkPosition(m c:MovieClip) {
mc.onEnterFrame = function() {
if (this._x>=Stage .width) {
//trace("right");
this._x = Stage.width-this._height/2;
}
if (this._x<=0) {
this._x = this._height/2;
}
if (this._y<=0) {
this._y = this._height/2;
}
if (this._y>=Stage .height) {
this._y = Stage.height-this._height/2;
}
};
}
public function chkcoll(mc:Movi eClip, obj:Object) {
if (mc.hitTest(obj )) {
// this._y = 249;

}
}
}

hmmm.. i could use some clarification on your exact problem, i didnt really get what you meant. few pointers, however.
1. it looks like you are commenting out your traces for run-time, ect. just fyi, under publish settings, flash tab, you can check not to export traces. this will lower your bandwidth a little, and allow you to put in as many traces as you want without worrying.

2. right here.. "if (this._x>=Stage .width) { this._x = Stage.width-this._height/2;} " it looks likt you are trying to say "if i am off the right side, move me to the middle of the stage(not the middle of the mc, is what i think you are going for). however, you are looking at the height, not the ._x characteristic, the width. try something simpler, like this._x = Stage.width/2;

3. when you are inside a function () { }, using "this" references whatever called the function, so mc_instance.OnR ollover = function () { this.gotoAndPla y(1);} is going to go to and play frame one of our mc_instance. if you want to be in reference to the frame you are on (aka if you want to control a different movie clip), just leave out the "this" and it will be in relation to the current frame

hope that helps
