Actionscript 3 :: Reduce The Area For Hittestobject - Flash Cs5?

Aug 27, 2011

I'm making a simple snake game in as3. the problem I'm having is that the stroke on elements slightly overlap thus when the snake passes by the apple in an adjacent square it triggers hit test object. If i reduce the size or stroke of either the snake or the apple then they dont properly line up to the grid. is there a way i can use hittestobject but reduce the area of the object that will trigger it. ie only trigger if it hits the center of the object?

//this will hit when snake is adjacent due to overlapping strokes
if(snake.hitTestPoint(apple.x,apple.y,true))
{[code]............

when I traced the values for the bottom code the values are what would be expected but some reason hitTestPoint wont trigger. strangely if I do + 1 it will still work but because the stroke is 2 i need at least +3. If i set apple.x+n as a variable and use the variable in hitTestPoint it wont trigger. also on all cases where it does not trigger i get no errors and all trace values are what you would suspect...

Flash :: Determining Visible Area/invisible Area Of A Masked Object?

Sep 29, 2011

I have a movie clip named circle_mc(see the image on the link below) and a mask object(movie clip) which determines visible area of the circle. User can change the portion which is visible (extend the red area and make it red+blue, gray area is invisible). I need to find proportion of visible area to invisible area (red+blue/gray) so that I can calculate angle.

ActionScript 3.0 :: Flash - Game HitTestObject Error?

I'm new to ActionScript but I've been following Lynda tutorials and  tried to tailor them to my game. I simply want to make my character at  the top of the screen shoot at enemies below. The error I'm getting when  I press the shoot button is "Parameter hitTestObject must be non-null." I've read some other forum posts on this error for ideas but still can't seem to make mine work.

Flash :: Papervision 3d HitTestObject Doesn't Work?

Jul 4, 2011

I'm new to papervision 3d and I created two display objects in basic view.
Here's a part of the code :

...
_stick = new Cube(materials, 50, 5, 500);
_ball = new Sphere(new ColorMaterial(0xfc0000), 80);

In the onRenderTick method, I tried to check whether two objects are hitted

[Code]...

However, stick.hitTestObject always returns false even if the stick really hits the ball as I see in the flash.

Flash :: AS3 - HitTestObject Collision Not Registering Correctly

Aug 7, 2011

I had a problem with my hitTestObject collision detection a couple of days ago which has since been fixed (How can I solve my hitTestObject Collision Null Object Ref Error) with the help of you folks. My problem now is as such: When my "enemy.hit" comes into contact with "player.hit" it registers as a hit - this is good. When my "building.collide" comes into contact with "player.hit" it registers as a hit - this is good.

However, when my "building.collide" comes into contact with my "enemy.hit" it does not register, but sometimes it does register even though the only enemy on-screen is many pixels away from it - as if either the building or enemy "hitBox" is somewhere other than directly on the graphic(MovieClip in this case).

ActionScript 3.0 :: Flash Stopping A HitTestObject After A Certain Frame

Jun 7, 2010

I am placing my code within frames and using the code below to hit test an object. After the animated object leaves the stage, the hit test starts getting errors because it is now looking for an object that isn't there. NULL

Code:
var o1:MovieClip;
o1.addEventListener(Event.ENTER_FRAME, o1hit);
function o1hit(Event) {

[Code]...

So the question is: How can I get the Hit Test to stop after a certain frame? Or does it have to do with the EventListener?

Flash :: Professional - Reduce File Size Of Opening Page In A Site

Sep 27, 2011

I'm using the Flash CS4 IDE, and the first page of my site takes a lot longer to load than I want it to.  So I wanted to go through the varied images / symbols / movie clips / sounds and so on to see where all the memory is being chewed up. When I go into my library, however, I can see the Name, LInkage, usecound and Type of my elements, but no mention of file size and I can't seem to find any right click menu that lets me add file size to the list of details being displayed. Is there a way to make it show file size?  Or some workaround? And are there any best practices to reduce file size aside from using symbols for anything that's used more than once and reducing image and sound quality?

ActionScript 3.0 :: Flash MovieClip - HitTestObject For The Collision Detection

Apr 28, 2011

I have a bullet object and a boulder object (both movieclips originating from JPEGs) in my AS3 game. The trouble I'm having is with hitTestObject for the collision detection, as it's taking in to account the transparent areas and basing the collision on the bounding boxes surrounding the movieclips. This is a problem because the collisions are not accurate and if the bullet (long and thing line shaped) is at an angle...the bounding box is quite large around it...and it's "colliding" with the boulder even though it's visibly many pixels away. Is there a way to detect MovieClip collisions that ignore transparent areas?

ActionScript 1/2 :: Decrease Hit Area - That Mouse Out Of To Make The Drop Down Area Pull Back?

Jul 28, 2009

i have a drop down menu am working on and each button tab (although they are not button instances !) when clicked opens up the "drop down" section which you can mouse over to choose another specific button etc - if you mouse out of that drop down area then it pulls back up to the original tab state ..  what do i change to the code below to decrease the area that you mouse out of to make the drop down area pull back .....at the moment it at least two inches on the screen below and to the right of boundaries of the drop down box before it pulls up - i want to it pull up as the mouse leaves the boundary box .... hope this makes sense .... there is some part of the actionscipt below that controls this but can work out which bit and how to change it !!! (am guessing the x mouse and y mouse bits - but how to change it ???)

ActionScript 2.0 :: Load The Area Of The Xml File Into Text Area On Mouse Click?

May 21, 2004

I would like to first add the xml to my flash. Fine I can do this.But I have a number of buttons, where when I click say CW1, i get the information from the XML file with a node of CW1. I have all the xml set up fine.As I have about eight different postcode types.

ST, CW, CH, TF, WV, WS, DE, SK, SY, and each of these may have numbers that follow, i.e ST1, ST2, ST3 and so forth.

So I can only assume that the postal area could be the main nodes, and the numbers inside the child nodes, am I right thus far.o how can i load the area of the xml file into my text area on mouse click, pulling the information relating.

ActionScript 3.0 :: HitTestObject Issue In A Bass Class Of A Library Object In Flash Pro?

Jan 18, 2012

i have a flash file with a number of movieclips  in the library - various bubbles that can be popped at a clilck. The fla has a document class - BubbleGame.as, and the various bubble mcies in the library are all exported for action script, (using their own names, but) with a mutual Base Class - BubbleBase.as, in order that all the various bubble movie clips have the same behavior: load in a random position, play out their own timelines, be popped when clicked, and if not popped - reload in another position.
 
This is all working very well, however, I want the movie clips removed if they hit an object on the stage. The object has an instance name of sym_mc, and I have tried various bits of code to cause the bubble to be removed when it hits that object, but i either get errors or nada.
 
I tried doing the hitTestObject code in both the  document class and the base class. It seems more appropriate to have it in the base class - BubbleBase.as (below), because that tells the bubbles what to do.
