ActionScript 3.0 :: Accessing An Instance Of Parent Movieclip For HitTest?
Dec 13, 2009
I have a stage with instances of bauble_mcs on it that are attached by the document class of the main timeline (can someone tell me what the right term is here? I don't know what I call the main time line in AS3).I then have instances of snow_mc attached by the same class. Inside the snow_mc I want to test to see if it is hitting any bauble_mcs but I don't know how!
inside snow_mc I am trying:
PHP Code:
if(this.hitTestObject(this.parent.bauble_mc)){
}
to which flash says:
1119: Access of possibly undefined property bauble_mc through a reference with static type flash.displayisplayObjectContainer.
I have a "MainSWF", that loads and places other SWFs "LoadedSWF". The LoadedSWF has buttons that are supposed to make some layers in the MainSWF visible/invisble. These layers are in a placed navigation bar that is defined as a symbol, was placed on the Main Stage and given the instance name "FlashStageMainNavigation". I have a hard time figuring out how to address the layers in the MainSWF, because it seems I am missing something.
When I use a loop to trace all the child instances on the stage of the MainSWF with:
I'm trying to access a parent movieClip from the child movieClip
Here's what I want to do,
I've got a movieClip named wrong_mc, which plays for a couple of frames and on the last frame, its got a close button "close_btn" inside of it, now I wanna write the code such that when close_btn is played the movieClip "wrong_mc" should go and stop at frame1, I'm just not able to access this movieClip from the button.
how to access a movie clip/s in a parent swf from a child swf. for example:Interface swf has buttons as mc's (home, about, services, portfolio e.t.c.) and loads in a swf when one of the buttons in the interface swf is pressed. When a button in Interface swf is pressed none of the other buttons can be pressed until the swf of the button that was pressed has loaded.
The reason for this is so that if the user tries to press the buttons quickly lets say the user pressed services button but changed thier mind right after pressing it and wanted to press lets say portfolio button they couldnt press the button until the services swf has loaded. Ive seen websites that dont do this and is makes it all mess up. Ive been able to do this in the past in AS2 but i cant figure it out in AS3.This is the code i would use in AS2:
Interface swf code is: ActionScript Code: _level5.btn_1.enabled = false;[code]...........
var lightBox:mc_lightbox = new mc_lightbox(); lightBox.x = 300; lightBox.y = 200; addChild(lightBox);
I get a lightbox up on the screen, within the lightbox is some more script, there are three menu options for that new window. So far when you click on it the loading part comes up just fine but whenever I have it go to another scene it leaves behind the lightbox above. I'm able to removeChild(loading) because its right there just a function above but I'm unable to removeChild(lightBox) because it's one up. How can I access that child? I tried many variations of parent, MovieClip, and root relationships but still couldn't get flash to find it.
I've been using asGamer's excellent set of game design tutorials to put together a basic 'ship and enemies' shoot 'em style game - my first proper venture into using AS3 and external class files - and I've hit a problem with executing hit test results. To explain: The game uses Engine (the document class), Ship and Enemy classes. Enemies (new instances of the Enemy class) are added to the stage in the Engine class, where they are also stored in an array, enemyList. The Ship fires a Laser, and the Laser class is where we test for a hit on Enemies.
Now, in asGamer's original version he uses the hitTestObject to test for hits, and if a hit is registered, this line PHP Code: Engine.enemyList[i].takeHit(); Calls a function in the Enemy class to remove the relevany clip. However, as the hitTestObject includes the bounding box of a clip in its hit test, I decided to use Corey O'Neil's Collision Detection Kit for greater accuracy. The CDK CollisionList class returns an array, the each element of which is a clip with which the target object has collided.
The problem this presents is that rather than using PHP Code: Engine.enemyList[i].takeHit(); To deal with a collision, I now use PHP Code: collisions[j].object1.takeHit(); Where 'collisions[n].object1' are the movie clips hit.
When I test the game it throws an error PHP Code: ReferenceError: Error #1069: Property takeHit not found on com.asgamer.basics1.Laser and there is no default value. at com.asgamer.basics1::Laser/loop() Although the movie does not break, and continues to remove destroyed enemies as if there was no problem.
What the problem is with calling the takeHit function via the collisions array rather than the Engine.enemyList array? And perhaps suggest a way to prevent it? I should point out that the 'laser' is in fact a blast that can take out any number of enemies intersecting with the blast radius, which is why I'm using CollisionList to detect hits.
i just would like to know how to create an "hitTest" script inside a movieclip that is actually part of that hitTest code?I mean... I have mc A, and mc B. and the current hitTest code im using (that is on the timeline) makes mc A, destroy mc B when collide with it... but there are many mc B on the stage (with the same instance name) so, when mc A collide with one mc B, it destroys ALL mc's B... but i want it to destroy only the mc B that he collides, not all the others... maybe an hitTest script inside a movieclip B would work (somethig like "if MC A hitTest ME = i die" (not all the others)).
I'm just wondering if hitTest can be affected by the changing x,y coordinates or the changing scale of the parent clips. My platform engine doesn't seem to work everytime I try to add a script to a parenting clip (of a playable character and a computer character) that changes the x and y values of that clip as well as the scale (simulating a camera that keeps both characters in focus).
I'm creating a platform game, and I have those boxes which needs hitTests on all sides - including the bottom.I want my hit areas to have the same instance names. With that I mean, that I want only one instance name for all the bottom hits, one instance name for alle right hits - and so on. If it's possible. 'Cause else there will be so much actionScript code to write.I've been trying to simply make a normal hitTest on for example hitGround, and then place two movieclips with the instance name hitGround, but the hitTest function only works on the last added movieclip with that instance name.I have also been trying to look up some for each in-arrays, but I don't really get the meaning of how to use them.
I am trying to make the instance 'red' be removed when all 3 objects have hit it here is my code:
var hit = 0; addEventListener(Event.ENTER_FRAME, hittest); function hittest(e:Event){ addChild(blue);addChild(green); addChild(pink); addChild(red); [Code] .....
I am trying to access a function that is on my document class for my AS3 project, from a nested class. That is, the Document Class calls Class A which then calls Class B. So I am trying to access a function from Class B, I am trying to use MovieClip(parent).function(); but I am getting error 1120. The MovieClip(parent) (fixed to reflect my document class, etc) works when I try it from other classes but not from this nested class.
I've struggled with this for a long time and have thrown in the towel. How the heck do you climb the ladder, then go back down again into another clip?
I'm trying to access the AchievementScreen's textfield from a medal object. Point being to have a mouseover event of the medal, change the content of the textfield shown. I tried a trace first: trace(this.parent.parent.parent.parent.textLineCon tainer); 1119: Access of possibly undefined property textLineContainer through a reference with static type flash.displayisplayObjectContainer. trace(this.parent.parent.parent.parent) shows me it is a AchievementScreen object. textLineContainer is the instance name of the MC nesting the textfield (I actually drew the achievement screen then exported it to actionscript.
I'm doing some work with JSON in as3 using as3corelib (very useful) and was wondering if it is possible to get an object if all you have is one of its properties, also an object.Here's an example of some JSON:
Well, I know how to access the loaded swf variables from its parent, but how do I access the parent SWF variables from a loaded SWF?! I'm trying it.. But get no results.
This is probably a fairly easy answer, but I can't figure it out. I have a dynamically added child, and I have a dynamic text box on the parent. I'm thinking that it should be possible for me to add to the text box from the child timeline, but I don't know how to target the text box.
I've been using greensock classes in a parent movie, but am now looking to use the same classes from within some child movies, but it doesn't work (I presently have to import them into each child movie - what a waste).
Do I need to create the classes as a shared library object perhaps? If so, how would I go about it? as I've only ever done this for MCs or MP3s.
What's the strategy for getting a child to access variables in a parent.I have a Main class.In that class I create instances of a Unit class and save those to an array.In the Unit class, I want to access the x and y coordinates of other instances of the Unit class.So I'd like to access that array I made in the Main class.I tried:this.parent.theArray[i].xbut that doesn't work. I tried using the get command, but I don't really know how to, so my efforts failed.
I have a .fla file with some code in the actions panel.A bit of code calls a function in a class from the actions panel .The function in the class is run, but I want to be able to call a function in the main actions panel code from the function in that class .The class doesn't extend anything so (parent as MovieClip).function() does not work.
I have several custom components all of which are included in the parent application.When I try to change state from a custom component, I get an error saying "undefined state: state name". How do I change the state of the application from within a custom component ?
ActionScript Code: function createMaskBox():void { var maskBox:MovieClip = new MovieClip(); galleryContainer.addChild(maskBox); }
creates maskBox under the function therefore not accessible form outside of this function from what i understand. Is there a way to create a var WITHIN a function which would exist as if defined outside of it, directly in code?
i am trying to make a basic preloader for an AS3 site. I followed the tutorial on this site (Preloading actionscript 3 the easy way) where its similar to AS 2 - create a Preloader movie and load the whole .swf into it.
only problem is i need some variables that i pass to the movie via QueryString parameters in the Object and embed tags. Is there any way to get this in my loaded movie?
i have tried root.loaderInfo.parameters and stage.loaderInfo.parameters and parent.loaderInfo.parameters
none of them work. Can i create a variable in the prelaoder and just go "parent.thevariable" ? or does parent even work when something is loaded into a loader?
