Flash :: Using Boxes For Hit Collision?
Jan 31, 2010
I am trying to use boxes for hit collision. I want to be precise with the collision so I was thinking about making multiple small boxes and checking for collision that way. This maybe a stupid idea or a smart one. If I do this way will that affect the performance of the game even though the boxes are invisible and wont be drawn on the stage.
map out the object starting from its center outward. Like right, left, top and bottom. I am creating a flying shooter so the plane has a long wing span. I could also map out the wing span and tail and so on.

I'm making a program that draws a grid of boxes and the color of the box must be different to those adjacent to the box. My code compares the current box's color to those to the left and top. If any of them matches, it picks another random number (as the color). For the tiles on the first row/column, I make my grid's array indexes with negative numbers -1 so that it will not match.
What I have:
private function fillArray():void {
grid = new Array();
grid[-1] = new Array(-1,-1,-1,-1,-1); //paddles the grid[-1][0 to 4] with -1
for (var i = 0; i < HEIGHT; i++) {

I'm trying to animate a simple stick figure just now. I used an inverted triangle shape for the body,which gives a nice width to the shoulders. Unfortunately, flash doesn't seem to realise that it's a triangle. Due to it's stubborn way of drawing a rectangular bounding box around every shape.
This is getting in the way a lot, as there are parts of figure which are clearly not blocked by the torso, but are blocked by it's big square bounding box, which makes it a nightmare to drag the arms and legs around to where I want them
Is there any way to fix this silly behaviour, and have it only select an object when I click on a visible part of it, and not just anywhere in it's bounding box ?

Is it possible to set up comment boxes on a flash movie? For instance, if I am viewing a page on my flash movie and I wish to make a comment on it, is there a way to set up a comment box and also show all of the previous comments as well? I figure it is but I am just unsure as to how to start it.

I am a PHP Developer, I know nothing about Flash and with all respect I do not want to know anything about. I develop a CMS which provides the backend for a Flash front end. Data is passed to the template via XML. Everything is grand. The problem is with text formatting. Currently we use the dodgiest flash text formatter. It doesn't work half the time, its horrible but it - just about - does the job. I have been tasked with replacing it. I would like to bring in CKEditor or TinyMCE but when I do I have 2 major problems.
1) Pre-existing HTML messes up the display in TinyMCE due to its invalidity (I can solve this.)
2) The TinyMCE HTML breaks the flash template because of the valid HTML.

I have an interactive assignment in which the students have to enter text entries into an input box. I have it working to where when the enter the correct answer it will tell them, or if it's wrong. I need to be able to tell them when they get to the last question, after they have gotten all of them correct, that they got all the questions correct. I know how to do this with a drag and drag interaction but not text entry. can someone point me in the right direction?

Im working on a project which includes a text editor in Flash which works perfectly but im trying to alter the code so the editor works over several input boxes rather than just one. Using Flash CS4 btw. Here is the actionscript im working with. If someone could give me some pointers as to how to allow the code to edit text in multiple boxes i would be eternally grateful.

I wanted to report a problem I've been having with Flash CS5.5 on MacOS 10.5.8 When I drag an element (usually a line or shape) with the alt key pressed (in order to create a duplicate on the stage) sometimes I get a couple of message boxes appear that say "Panel x could not be created removing it from the list" where x is a number like 7 or 9. After I click through these the swatches panel appears in the middle of the screen.
This is quite annoying and holds me up as I have to click through these boxes & then close the swatches panel.

The flash is loaded with SWFObject v1.4.4 with XML 1.0
Here is a part of the index.html:
<script type="text/javascript">
var so = new SWFObject("swf/kj.swf", "KJ", "100%", "100%", "8", "#000000");
so.addVariable("xmlPath", "xml/publish.xml");

So I have a movieclip in my flash that has an event listener that calls it to pull up when the mouse is over and go down when the mouse is out. Kinda like a menu. But this object that I am accessing has text over it. The problem is it works until the the mouse that hits the text over it. Then it drops down.[code]

I have a PHP file which is correctly pulling records from a SQL database. What I need to do is place each new record into a new text box. I understand that I need to assign a variable to each record as it comes through the PHP file and that Flash needs to know which variable to assign to which text box. So, in that respect I have added a counter to the PHP script (it is performing correctly)

I'm trying to insert some data into my DB from two Combo Boxes in Flash. I'm not quite sure how to go about it. I have no idea how to give the combo box a 'var' value like we do for a regular textfield. I have other pages where I have regular text fields that work fine as I can specify the 'var' value in the properties but not for combo boxes. I'm new to actionscript so please bear with me.
Action Script for my button:
Code:
on (press) {
loadVariablesNum
("http://localhost/Test/acadForm.asp",0, "post");

I was told the pixel detection is costly for regular windows games. Is this the same for flash ?? Or would pixel detection be lighter compared to other detections flash has to offer. Flash has the getPixel32 method which makes it easy for detecting pixels. If I am bliting my game, would it be wise to use getPixel32 for collision detection. Or should I just check for specific tiles?? Is getPixel32 limited to the display object it is in ?? In other words, can I detect any pixel regardless of what layer it is on in the display list.I probably can figure this out on my own but I want to ask first to save me some time. But does anyone have any code or good sources on how to go about doing this if it is reasonable.

I am trying to figure out the collision physics for a top-down racing game in Flash / AS3. I am currently using the hitTestPoint method for detecting collisions, but I don't know how to apply a decent physics method to bounce a vehicle off of a wall that it hits.

I'm starting to understand ActionScript and getting better with it. However, I'm building a platform game with an unlimited length. What would be the best way to create the "block" the player is jumping on?
Of course collision detection for these movieclips is needed (nicest would be to do it without a giant loop through an array, etc. on every frame). There's probably something like 5 block on the screen at the same time.

I am in the progress of making a Flash game and currently I am doing the coding for collision detection. The collision detection will be for detecting if the player is running into obstacles, and if the player runs into the obstacle, then it will stop him from running through it. Here is my code that I am using for collision detection:

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).

I'm trying to make my first game in Actionscript 3. Its a simple artillery game where you have a gun at bottom left corner and AIs flying across the screen which you have to shoot down. Now, in a classing shooter game how this is achieved is either by firing a bullet from the gun and doing a hitTest of that bullet with the AI movieClip or by simply removing(or playing the death animation) the AI movieclip. But here's the problem. I dont wanna do either of them. I want to show a gun with a rapid fire rate and hence no bullets. And I also don't want the player to click exactly ON the AI movieclip to destroy them (just the gun/turret pointing at the correct direction should be enough). So here's what I tried. This image should help picture the whole thing.
Tried attaching a 'line' to the turret and checking for collision with AI clip. This obviously failed because of the bounding box problem when the line is slanting.
I tried putting multiple tiny movieClips ON the line and iterate through them in a loop and checking for any collision with the AI. This method partially worked, but it was too slow and didn't seem like the 'correct' method. I draw 2 hypothetical lines. One between p1 and p2 and other connecting p3 and p4 (please see the image above). p3----p4's lenght = AI.width and is a horizontal line running right through the center of the AI MovieClip. Upon mouseClick I check for any intersection between these two lines. Now if I have multiple AIs on the screen, Again i need to iterate through each of them, draw a fresh p3-----p4 and check for intersection with p1-----p2.

I am having trouble with getting some code dealing with collision detection to work. I have tested to ensure that it does detect the collisions, and it does, however I am unable to get it to work as it just walks through the block. I also tried just taking away -10 from the x value after it collides but it will stay for the first couple of tries then just walk through the block.
private function collisionDetect(evt:Event):void{
if(IMG3.hitTestObject(block)){
if(IMG3.x > block.x){
IMG3.x = block.x-1;
}
}
}

I am trying to use hitTestPoint to test whether the x/y coordinates of many circles are colliding with the pixels of another movie clip, but it is not working. It works fine when the ShapeFlag is set to FALSE, (circle detects the boundary box), but not when ShapeFlag is set to TRUE.I have spent hours trying to figure out what could be the issue, but to no avail.Class Ball - called by MAIN program multiple times to create instances of Ball and bounce them around the screen. If Ball collides with DQ (another MovieClip on stage), then it should stop moving:[code]

I have the values (x, y, xSpeed, ySpeed) of the movieclips (Hero and Badguy)Now, when they collide, how will i calculate how hard the collision is?Obviously weight, acceleration, etc. are out of the question, as it just needs to be based on their speeds.

I have a movieclip called nest, which also contains a movieclip called wall. The bullet is created in the nest movieclip, and I am trying to make the bullet disappear when it hits the wall.The problem is, when the bullet is at B, the hittest succeeds when there is nothing at b. [code]The bullet just passes through the walls.

I have to dynamic text boxes; one is for articles and the other is supposed to bu for navigation of the articles. I have a variable set up for the article dynamic text box and I want the navigation part to be filled in via text file. so I need to find a way for the information that's fed in to the navigation part to functions as buttons and when they are clicked a variable should pass though flash telling is what story to display. for instance if you click stereohype then storyvar == stereohype. see what I mean? I could do it all in flash but i'm trying to make it where I don't have to touch the flash file after it's completed and everything can just be manipulated via text files with html php xml you name it, what ever works.

I have to create a flash control which has 3 text boxes in 3 rows. please see attached screenshot. & all the text boxes have dynamic content & different style.
what happen now, when i have more content in the text boxes, it overlaps to the other, don't adjust accordingly(when we have more content in any text box the other text box beneath it should get down from current position). I tried lot & researched on the internet lot, but didn't get any solution for that.
