how difficult is it to create a flash game with a racing car picking up dots (movie clips) that give points?I managed to have the racing car moving and add something like wall boundaries but i cant find tutorials online that are clear about the colision detection...and the dynamic text field that scores points.
View 2 RepliesI have an array of points that I will use to generate a closed polygonal fence on the outside of a game stage (2D). I wish to have collision detection between this fence and a bouncing ball-like object on the inside. Additionally, I would like to be able to arbitrarily add/remove/redraw the fence in realtime and have the collision detection still operate realistically. I have considered drawing a Sprite/Shape from the points and doing a HitTest at each frame to check whether to bounce or not. My question: is this the best/correct way to accomplish this goal? Consider something like JezzBall with diagonal lines of any angle a simulation of what I'm trying to do.
View 2 Replieshow to work out the direction of the mouse on stage and say from this:
"if the mouse goes from the left to right (visa-versa) once, add score +1" and "if the mouse speed which is player controlled - slows down - to then display an error graphic"
Is there any as3 based source code that accomplishes pitch detection or beat detection accurately? Doesn't have to be both, if you know of at least one of those,
View 4 RepliesI have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.
I am trying to create a mindmap where the user can drag points about the screen. I have gotten as far as drawing the line via actionscript, and drag+drop the points (defined as movie clips on stage). This is the existing script - I don't know how to get the lines to follow the points. Something to do with ENTER_FRAME or updateAfterEvent?
var line:MovieClip = new MovieClip();
line.graphics.lineStyle(1,1);
line.graphics.moveTo(ptOne.x,ptOne.y);

I have already tried this and it comes out as staying on until you leave the page or mess changes.[code]What can I put to make the "CAPS LOCK IS ON" go away when the capslock is off?

i have a snake game, that after time loads sprites in an array to make the snake grow. Just wondering how i would go about adding a hit so when the head of the snake hits the body something happens. Below is the full document class code.

I was wondering what do the AS3 experts would do to detect a color with the webcam (red) and draw a sprite on those color boundaries.

I want to make a flash movie that detects OS in use, and if its Windows, go to a frame, if it's Mac OSX go to another frame, and if is another OS, go to other frame...
I know this is possible, but I don't know how to apply it.I know I can use System.capabilities.os but I don't know how!
Im using CDK, and I want to exclude color black.im using this: __collisionList.excludeColor(0x00000000);
View 5 RepliesIts been many years since I've used flash and I was just wondering what the easiest way to do collision detection was now. I know that there was some hit test bounding box stuff present earlier but I don't know the capabilities of flash cs4 and the advances that have been made. Google searches have yielded things like complex pixel-perfect collision detection but not a lot seems to have been written about CS4 yet.

I am trying to get some collision detection working. What I have is a ball moving around the stage. There is a box in the middle which when the ball hits, I would like it to bounce off the box. I can get the x axis working fine using hitTestObject but when I detect for collisions on the y axis, the two axis conflict. Does anyone have a way of doing this properly?[code]

View 1 RepliesSo I've been googling around for information on detecting collisions in AS3 and I found this page which has what troy claims to be a 'pixel-perfect' collision detection algorithm:[URL]..

1- i have a circular menu, with a zoom effect when you hover on it, with the home button in the center, when you click the home button you load the page then reload the scene 1 ( menu idle ).If i put nothing on the button itself on the scene 1, before the zoom effect, i need to move out of the button to trigger the other scritp there that detect the rollover and start the zoom in.i want to have a special behavior for the home button on the idle state of the menu ( scene 1 ) , When you click the home button from anywhere else, you load back the page, then because the mouse is already on the home button, i want flash to do nothing, but at the second you start to move the mouse again ( remember you are still on the home button) i want it to start teh zoom effect again, not before.
Right now, it is either no zoom effect as soon the mouse is on top of it, or imediatly zoom in with the rollover....And i know it is possible with a very simple command, but i forgot it... i did it before.2- for the same menu, i will have a sub-menu unfolding when you click a certain button, that sub-menu is outside the main menu detection zone. Is it possible to make a shape, turn the alpha at 0, put it under the sub-menu, and use it as detection zone
With AS, can I trace that user hasn't been operating on the computer for a while, say 5 miniutes, and then do something? theoretically speaking, to detect that there is no mouse or keyboard event for certain a period of time, and then do something~~ just like screensaver of Widows~
View 1 RepliesHitTestObject seems to check collision of bounddaries of shapes, it seems to consider everything rectangular. Also if one object jumps two pixel and other five pixels on EnterFrame it seems like there won't be any hit detection. Seriously guys what else method do you use, if you use hitTestObject how do you use?
View 1 RepliesI have 2 boxes in stage and I want to drag any where in free space but cannot through the boxes, if I drag box1 in the upward direction and collides to box2 , then box1 cann't be drag in upward direction but it can move(drag) any other three directions.
View 1 RepliesI'm making small interactive games in flash to learn AS3,I need to check the collision between the player and the wall which is normally simple using the hitTestObject function.But now I made a wall object totally surrounding the player with corridors and turn, a collision playground so to speak. Now when I use the hitTestObject function to check whether the player is in collision with the wall it tells me it always collides supposedly because the player object is within the bounds of the wall object.So assuming that I'm correct about the error:How can I prevent getting a collision when I'm inside the bounds of the wall object but not touching the actual walls in that object?

View 1 RepliesI am currently trying to implement basic speech recognition in AS3. I need this to be completely client side, as such I can't access powerful server-side speech recognition tools. The idea I had was to detect syllables in a word, and use that to determine the word spoken. I am aware that this will grealty limit the capacities for recognition, but I only need to recognize a few key words and I can make sure they all have a different number of syllables.
I am currently able to generate a 1D array of voice level for a spoken word, and I can clearly see, if I somehow draw it, that there are distinct peaks for the syllables in most of the cases. However, I am completely stuck as to how I would find out those peaks. I only really need the count, but I suppose that comes with finding them. At first I thought of grabbing a few maximum values and comparing them with the average of values but I had forgot about that peak that is bigger than the others and as such, all my "peaks" were located on one actual peak.
I stumbled onto some Matlab code that looks almost too short to be true, but I can't very that as I am unable to convert it to any language I know. I tried AS3 and C#. So I am wondering if you guys could start me on the right path or had any pseudo-code for peak detection?
I'm trying to make a game like Mario. I've made a character which can jump right now, but I've got some problems with collision detection.
I would like my character to jump on a bar, which is placed higher. My collision detection doesn't work at all I gues..I've made a cirle which has a instance name mcMain and I've made a MovieClip of it. T also made a rectangle which has a instance name balkje, I also made aMovieClip of it.
I hope you can tell me what is wrong about my code and what I've to change to make the collision detection work!

View 1 RepliesI have Object "A" that moves around and collides with other objects. There are hundreds of other different objects it can collide with. The only way (I found) to test for collision is to loop through every other object. That seems rather inefficient considering I don't even know how many objects exists. Other objects are constantly created and deleted. So this loop would be rather complicated.Is there a way for object A to receive what other object it collided with so that I can then do some code on that other object. Any way to avoid looping? I later need to find out how to detect what objects are near (within x pixels or so) of object A to decide with which one to interact. Maybe that could also be used now to limit the test of collision? Or maybe it gives someone an idea of what to try?
