I need to know how to have an object be recognized when it passes over a point on my stage. Then once that has happened an event happens such as a new screen appares.
View 3 RepliesI am using AS2 with Flash 8 Professional So, my problem is that I currently have a man in the middle of the screen, who shoots a line towards the mouse when I click. However, when I use hitTest to see if the line collides with another object, Flash recognizes the line as a large box if it is diagonal, so the hitTest isn't very accurate. The line only satys there for one frame, so I can't have the usual moving-bullet-style. I am either looking for a way to create an imaginary line with AS from the starting point to the mouse and beyond, and tell whether or not this line intersects with an object... or some other way that I haven't thought of to fix my problem. Keep in mind that the line rotates from a center point towards anywhere around it for 360 degrees.
View 1 Replieshow to use these in order to make an object move from point A to point B in an arc.Think of that classic game where you have to input the angle and power and try to hit your opponent.
View 1 RepliesBasically what I like to ask is how to move a object from one point to another point based on the point tat you have clicked on a graph. For example, If I click on this coordinate (2,3) on graph, the object (movie clip) will move to that point.

View 7 RepliesI'm still new to AS3, and I was wondering how to make an object point in the direction of another object and move towards it if they are a certain distance from one another. I haven't been able to find out how to do this from the Adobe devnet, so I thought I'd ask here.
View 1 RepliesI need to detect collision between my bezier curve (drawn using curveTo method) and a object, the curve is dyanamic and hence the equation changes every frame. I am looking for a efficient method to detect collision between curve and the object.
View 1 RepliesI 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).

I am wondering if there's any way I can track objects in Flash video using ActionScript? For example, let's say I would like to track a red ball, how can I do this? I have seen some examples using the OpenCV port but the examples shown are for face detection. And I can't seem to figure out what's the difference between the OpenCV port and the actual OpenCV library itself. Is it a full port?
View 1 RepliesIn OpenCV, we can use a xml file to describe haar-like features of a specific object. I wanna use this idea to detect palm and fist, now I hava my own xml feature file, and it works well in C and Python(with OpenCV), now I need to move this idea to flash.
Luckily, I found an project named Marilena, it successfully moved the haar-trainning part of OpenCV to actionscript, and this article optimizing flash based face detection optimized Marilena, he turned the xml file into actionscript class itself to speedup the calculation. However, since the Haar data is being hardcoded into the class now it will not be able to use for tracking anything else but faces. I try to read the source code for detail, and process my own xml file into actionscript class file in his way, but finally find something different.
The xml file for face detection is like :
Every tree has only one node "root node", but in my xml file, some trees have two nodes, and the "left_val" above changes to "left_node" sometime, I don't know how to process these nodes. I think I should goto OpenCV C source files for detail to find how to correctly process xml feature file, but where to start,
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.
I've attached a zip with a few custom classes and a .FLA. Ignore the custom classes. I'm getting repeated
"Error #1009: Cannot access a property or method of a null object reference. at Environment_fla::MainTimeline/hitTest()".
I understand that this error means I'm asking it to reference something that's no longer there. How better to hitTest many objects in an array. My game involves creating a bunch of balls that will fall into buckets. I need to keep track of how many touched the buckets, how many fell off the screen, and remove each accordingly.
Here is the code from my main FLA
ActionScript Code:
var ballTimer:Timer = new Timer(200);
var changeTimer:Timer = new Timer(50000);
ballTimer.addEventListener(TimerEvent.TIMER, throwBall, false, 0, true);
ballTimer.start();
changeTimer.addEventListener(TimerEvent.TIMER, changeColor);
changeTimer.start();

I am trying to traverse object tree in AFL (adobe flash lite) engine, to check if there are memory leaks in an event driven application (AS3). The idea is to get object tree dump before and after an event processing and check the object tree dump difference for memory leaks.I believe MMgc is the GC for AFL, I am unable to get a dump of object tree, can anyone help me to point out where in code I can get the alive object info in tamarin.

View 4 RepliesI 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?

View 2 RepliesI have an object which is converted into a symbol. I double click on this object/symbol and it goes into its own seperate timeline. For my coding purposes I would like to know how to change the registration point of the symbol so it moves along or is addjustable on a symbols its own timeline so a can create animations on an objects timeline without screwing up my codeing because objects don't register when their moved away from the registration point the compiler still thinks that the registration point is where it was previously.
View 8 RepliesBasically if I have a sprite for example located at (10,10) I want to move it to say (50,100) and the whole process to take 2 seconds or whatever duration I specify. What is the exact math behind this? I was using a distance based solution to determine speed but was just using a random modifier to control the process. I need something more precise to execute exactly over a set duration.
View 4 RepliesI'm a relative noobie struggling to understand object registration points / center points. For example, in this image of an empty movie clip from an XML gallery I'm customizing for my site, there is a circle with a cross and an empty circle.
Can someone point me to a thread or article that explains object registration points, how they relate to each other and how (and why) to move them (or not)?
I have a rounded rectangle that the x and y values will always stay the same. However it rotates around and it's height is increased (it follows moving targets). (Think of it as a turret that shoots out a beam of light that will always be anchored to the turret on one end but it gets longer and rotates so that it constantly tracks the moving targets) I want to remove the object when it moves off the screen.
Normally I would just do this with:
(if myObject.x >= 550){
removeChild(myObject);
}
and the same for each other direction of the screen. However, as mentioned, it's not the x and y values that are changing - it's the height that's changing.
Now I've tried just swapping out 'x' for height:
(if myObject.height>= 550){
removeChild(myObject);
}
etc. for the rest.
But the problem with that is that if my turret (the anchor point for beam of light) is closer to the edge of the screen (i.e. it's x is 500), then it will take a couple of second's for the light beam's height to reach 550.
