ActionScript 3.0 :: HitTest() Point Of Collision?
Dec 4, 2009I've found the BitmapData.hitTest() function very handy, but limited for my purposes. I need to figure out at exactly which point the two images collide (in any coords system,really), since their behaviour will change depending on the angle of the surface hit

Nov 12, 2009I want to detect when a circle collides into a random object. I know this is pretty basic to do with a mouse colliding into a random object but I want to modify this for a circle. I have seen some examples which use circles but they are drawn in script, is it possible to do this with a mc from the library.

Feb 10, 2010im creating a circle dynamically with each click on stage, with the drawCircle function, now, that circle is a shape, not a movieClip, im arranging this circles inside of an array, and i want to check if they collide, so that second circle dont appear if its occupying the same space as the last one, or at least trace if they are colliding so i can do something about it....
i've made tests with movieClips and no problem, the mc1.hitTestObject(mc) works great but not so great with raw shapes, it just ignores collisions

Mar 28, 2005what i am trying to do is to detect a collision between an empty mc and an mc allready in stage.the empty mc is a line, which I draw with the mouse. when this line hits the other mc I want the colission to be detected. so far it doesnt work properly.the colision is being detected even if the line that i draw, doesnt hit the other mc. does it have to do with the properties of the empty mc, or the hittest method has to be changed?Here is the code:
_root.mc.onEnterFrame=function(){
if(_root.mc.hitTest(_root.line)){

Apr 9, 2011If you have a group of movie clips stored in an array and the movie cliops are placed on the stage randomly, and use your arrow keys to move a box on top of one of the movie clips - how can you "tell" Flash which movie clip you clicked on?
Right now I've got a for loop going which loops through the array that has stored the movie clip instances, presumably the hitTestObject would eventually get a hit...But this doesn't work, especially inside an event handler where when I press the right arrow on my keyboard.

ActionScript 3.0 :: Finding Collision Point And Normal Vector?
Aug 30, 2009I got a working broad phase and collision detection is fast enough.Now my collision response is working, but slow. I have trace(using getTimer()) through the whole resolving method, and I found the slow spot is where I get the collision point and normal vector.
Right now, I test each point on each shape against each line on the other shape. This works nice on triangles, but other shapes, it much to slow.I would think that using SAT(seperating axis therom) would have a way to get this when checking collisions, but I cant seem to get it.I need a fast way to get the collision point and normal vector.(Right now, it takes about 3 milliseconds per collison on a rectangle with 4 points and 4 lines)

View 2 RepliesActionScript 2.0 :: Generic HitTest - Detect Collision With One Object
Oct 13, 2005Right 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.

ActionScript 2.0 :: Movieclip To Move Along The X-axis To A Certain Point And Then Back To The Starting Point Again?
Apr 12, 2007It's been a long time since I've done any work with actionscript, and alas I've forgotten nearly everything. I've tried to look for a tutorial that would explain basic animation with actionscript, but the one that I found on Kirupa was no longer there.
Basically I'd like to do this:On the stage I have a movieclip and I'd like the movieclip to move along the x-axis to a certain point and then back to the starting point again. The moving speed of the movieclip should also be adjustable.
ActionScript 3.0 :: Distance From Point To Point And Referencing Other Instances Of The Same Class
Feb 8, 2009I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.

how to get XY, after rotation ( changeing point.rotation property to specific degrees of rotaion )
ActionScript 2.0 :: A Line From One Point Past Another Point And Whether It Hits An Object?
Aug 19, 2009I 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.
