I am currently making a game based on slicing other objects, basiclly when you hold down and drag your mouse and then release it an object that shows the cut will be created.

I need to know what side of a rotated box my sphere/point is colliding with and at what angle.
I could perform the 4 lines check but I think it will be too cpu consuming. I need it for fast simple physics simulations(bounces)..
it's easy to test collision between two squares. how do I test the collision if they are rotated?
View 1 RepliesIf I create a rectangle with 100px width and 100px height and then rotate it, the size of the element's "box" will have increased.With 45 rotation, the size becomes about 143x143 (from 100x100).Doing sometimes like cos(angleRad) * currentWidth seems to work for 45 rotation, but for other bigger angles it doesn't.At the moment I am doing this:
var currentRotation = object.rotation;
object.rotation = 0;
var normalizedWidth = object.width;

Here's the layout:I have a main SWF. Inside that main SWF is a container MC that has been rotated in 3D space to have a bit of perspective. Inside _that_ container is a container MC into which is loaded various images, videos, and SWFs. Images: no problem. Videos: no problem.The problem:If an SWF is loaded into the media MC that has an MC in it with a listener/startDrag combination allowing that MC to be dragged it seems to fail (the drag).I've tested this child SWF extensively to make sure the drag works, and I've even loaded it externally into other SWFs and it works. I've also tested in various ways to make sure that the problem isn't something simple, like an intervening clip in my main SWF keeping the MouseEvent from reaching the MC with the startDrag
View 1 RepliesI have the following display hierarchy:- - container- - - objectI need to draw 'object' to a BitmapData instance which matches object.getBounds(stage) rectangle area. So the first part is easy:

I have this enter_frame listener to make my Container MovieClip rotate on a 3D environment in relation to the position of the mouse.
PHP Code:
addEventListener( Event.ENTER_FRAME, loop );
private function loop( e:Event ):void
{
var distx:Number = mouseX / stage.stageWidth;
[Code]....
One of the MovieClips I load into that "ctt" container has some scrollable content. I've traced both the CLICK and MOUSE_DOWN events on the Dragger of the scrollbar and it's active, it receives the click and mouse_down events. The problem is that it doesn't drag.
I know that the scrollbar works because if I remove the loop enter_frame event I showed before it works perfectly, it just doesn't rotate on a 3D environment as I wanted it to.
why the dragger doesn't drag when that ENTER_FRAME event like that is being used?
I am currently creating a game in which the character is stationary in the middle and the world moves in relation to the character. When the character is not moving and not touching anything, I need the world to shift upward to meet the character and stop on collision detection. The problem is I have no idea how to conceptually make this work.
making assets "fall up" and stop when colliding with an object (basically reverse gravity).
I have three objects in the main scene (so far), one of them is draggable (up and down only), then the animated one that moves downwards and the start button (activates the animation). So I've been trying to figure out how to script the collision detection for the first two? The collision should take place not because I dragged the slider onto the animated block, but because the falling piece hits the slider after I pressed the start button.

View 1 RepliesI have two MC's on the stage. One of them is standing still in one position, the second one is moving towards it. I want the moving mc stop right at the very centre of the first mc. I've tried using hitTestPoint, but I don't know how to set the proper parameters. If I put there just: mc1.hitTestPoint(mc2.width / 2, mc2.height / 2, true), the trace function I use doesn't seem to have even noticed the collision...
View 1 RepliesIs there a way to test collision with a child of an object?eg.
ActionScript Code:
obj1.hitTestObject(obj2.childObj1)
obj1 and obj2 are on the same level of hierarchy.
I am trying to test when an object collides with a particular location of another object so i made a 1x1 movieclip (childObj1) and placed it inside obj2 at that particular position.
I read the tutorial about Multiple Object Collision Detection. What I want to do is have there be 3 circles and 3 squares. the circles are moving randomly while the squares are stationary. The actionscript would need to be checking to see whenever the moving circles collide with the stationary squares. However, it doesn't seem to be working. I followed the logic of the tutorial pretty closely, by making a separate list for the instance names. Here is the code for the collision detection.

I want to create a function in which I can drag a MovieClip which will bump into other MovieClips on the stage without overlapping them. (i.e. the object cannot be dragged over or through other MovieClips).

for(var m:int = 0;m<blockHolder.numChildren; m++){

I am creating a game where I have two separate arrays of objects that I need hitTested with each other. I found an old tutorial in AS2 that I modified to come up with this code:
ActionScript Code:
for (var w:Number = 0;w < enemyLaserArray.length;w++) {
for (var R:Number = 0;R < barricade1Array.length-1;R++) {
if (enemyLaserArray[w].hitTestObject(barricade1Array[R])) {
[code]....
This code executes like I believe it should, but along with removing the two objects, and splicing them from their arrays, I get this error
Code:
TypeError: Error #1010: A term is undefined and has no properties.on the line hitTestObject line. I have had similar problems in other areas of my project, but this time no matter what I try using trace statements I cannot fathom quite what the problem is.
Right now I'm working on an advanced hitTesting engine, and What I'm trying to do here is create an engine that will detect collision with one object instead of two. That basically means that if any other objects touch this movie clip, the hitTest will return True. Right now the .fla containing the engine has nothing but a circle that can be moved using arrow keys and 8 squares that disappear when touched by the circle. Obviously, I could do something like:
if (circle.hitTest(square1)) {
do so and so
} else if (circle.hitTest(square2)) {
do this and that
} etc...
But that would be too long, since the engine has to be able to contain 100 squares without too much change in the code.
so I have a function on the Main Timeline that creates an instance of the class Ball once every 60 frames (1 second). In the class code for Ball I have this:
Code:
package {
import flash.display.MovieClip;
import flash.events.*;

As you can see, I am trying to make it so that if two instances of the class Ball collide, then it should output "STOP". But it isn't working.
What is the most efficient way to text for a collision between an elliptical object, and an irregularly shaped object (closely related to a line) that rotates?

Right now I'm trying to make a sliding puzzle. So far I have a block which I can click and drag around, and a few walls which are the boundaries. What I'm trying to do is make an area where the block can slide within the boundaries. So when you try to drag the block into an direction it will stop, whether you got mouse_down or mouse_up. My script so far
Code:
stop();
//Sliding Blocks
MCBlock1.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);

Also I need to use a lot of boundaries, so if there's a way to apply this script easily to several objects
The scenario: in Main, instances of class Bullet are spawned and added to the stage, and to the array bltarray, instances of class Enemy are spawned, added to the stage, and added to nmearray. This works fine.
The problem comes in seemingly sporadically, i.e. it works, then suddenly doesn't work soon after, when it doesn't work I get spammed with output errors and the score display is constantly rising, note it's the same instance of bullet and enemy. [code]...
I have almost everything working except for collision with the bricks. This is based heavily off the "Flash Games University" example although several things are changed. When the game starts with brick collection detection in play, and the ball appears the entire thing freezes. I get this error: Error #1009: Cannot access a property or method of a null object reference. It repeats 28 times - the number of bricks. The error seems to be occurring at "var brickRect:Rectangle", according to debug and observing. It may be a scope issue, but what should I change to fix?

I am facing a curious issue. Generally when we draw lines in Flash either vertically or horizontally or through exact 45 degrees on either of the sides, they come out as straight and anti-aliased. While if they are drawn deviated from either 0 or 45 degrees, they come out as jagged. I want that to be anti-aliased too
View 1 RepliesWhen I select the text tool in Flash and click on screen to type, my text box is default rotated 90Ë clockwise. In addition, the text is default bottom aligned so when you hit return, the next line is above the first line. So, simply rotating it back doesn't
Even my properties box align buttons are rotated: I should add that the little rotation button you see for "orientation" is not the fix- it rotates individual letters.I can't find anything in the menus, toolbars or preferences to change this...
this math isn't working well. I'm using it for a rotated drag and drop (of a tone arm on a vinyl, a kind of abstract turntable simulation). Right now it just moves a bit in the middle of the vinyl (values between 21 and 36, is this degree or what unit is this?), but it should move between the two edges. The problem is that I don't know enough about trigonometry functions. Therefore I can't optimize the math for envisaged behaviour. Does anybody have an idea/tip how I can get a bit more control on the math and its effect? (maybe with more trace functions)

I have created a simple text scroll ( on (release) {object.scroll += 1} and it works fine.
Now the image in the background is slightly tilted so I have to rotate the text box a bit and I do this the text disappeares.
Any Idea how to get that rotated text box visible when rotated?
Is there a way to know if user's camera is 180° rotated ?
