I want to make a game using physics in Flash, so I stumbled upon Box2D, but i find that hard to use [the basics are simple, but when i see the scripts,so i was wondering if there are easy to use flash physics engines?
View 6 RepliesI wanted to study some physics code lines related to flash actionscript 2.0.Is there anyway to build a model with physics incorporated without a physics engine? By bare actionscript?If yes, can anyone show me a tutorial or an explanation to learn somehting about it, please?
View 0 RepliesI know you can add a var to add grvity and velocity ect. But what are the limits of this?Can i have a ball roll downhill using physics from within flash, without a external physics engine like box 2D.Can i have impulses? Well thats not important just wondering really.What can you do with physics in flash?
View 5 RepliesI've recently created a game in which the logic and programming all runs perfectly, however the graphics are lackluster. I'm currently having a hard time managing the depth of movieclips on the screen.Basically the game is tile based and each frame of the movieclip holds a different type of tile. All the tiles are 50x50 with the exception of one type of tile which is 60x60 and therein needs to overlap the tiles around it which are 50x50.In AS2 I could of set the depth manually, however I'm told (as is this is my first time dealing with depth in AS3) that I cannot do this anymore. Is there any suggestions on how I can make sure that a tile of one type is automatically set beneath tiles of another type - I've thought about simply coding a function to check this but it somehow seems inefficient (considering larger maps will have a lot of tiles, meaning hundreds of movieclips attached to the stage, each movieclip with multiple frames).
View 2 RepliesI cant get the flash to work on my website. I have also tried using countless versions of the 'AC_RunActiveContent.js' wrapper with this, but it just ends up as a white block, whereas if I just use the following code I get a black block. So I am certain that the path is correct because if I change the src path, it becomes a white block.

There are some open SDK for Flash, that could be done. Rotating photos with physics? Examples of such programs BumTop, ePic, Coloris (no physics). The photo on the plane, it can be moved to the real physics?

View 2 RepliesIntroduction: I think Nape is a relatively new engine so some of you may not know it. It's supposedly faster than box2d and I like that there is decent documentation. Here's the site: [URL] I'm relatively new to programming. I am decent at AS3's basic functionality, but every time I try to implement some kind of engine or framework I can't even seem to get it to work. With Nape I feel I got a little further than before but I still got stuck.
My problem: I'm using Adobe CS5, I managed to import the SWC file like described here. Next I tried to copy the source of one of the demo's like this one and get it to work but I keep getting errors. I made a new class file, copied the demo source to it, and tried to add it to the stage. My stage code basically looks like this:

I've made a character, and used the bone tool to make it move in runtime.This works fine, but now I want to add gravity/physics, so I can throw my character and it lands on the ground like a real ragdoll. How do I do this in actionscript 3 ? And is it possible to do this within the fla (no class file).
View 1 RepliesI 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.
View 4 RepliesI have a Cube which I want to rotate using mouse motion. So if I move my mouse to the left it rotates as if rotationX was increased. When I move right rotationX is increased. Moving Up and Down alters rotationY.
This looks fine as long as you modify only one dimension (either rotationX or rotationY). But if I have already changed rotationX and then try to modify rotationY the results are weird. If rotationX is 180 rotationY effects are reversed. It basically is quite unpredictable and certainly not suitable for user.
I have tried to look around (failed), read about quaternions (couldn't understand), tried some out of blue and very complex trigonometric calculations (made a fool out of myself) and so I am stuck now. I've found this SO question Best way to translate mouse drag motion into 3d rotation of an object but it doesn't help me a bit, I can't understand any of the answers, really.
Okay so I need to make a basic activity (working Flash/as3) that simulates very basic weighing scales. All the objects that go on to the scales are the same weight.
If you imagine the classic weighing scales [URL]..we are dragging/dropping stuff on to the sides and animating accordingly.
I don't want anything fancy, just the maths required to affect the scales according to how many objects are on each side.
What I'm looking for is probably the angle of rotation of the horizontal arm. Any pointers?
I'm starting a blog with a hosted wordpress instance and i would like to be able to stream music using a flash player on some posts.The problem is that every player i find uses a simple param to get the file url which makes it very easy for someone to find that url and just download the file.I know that it's probably impossible to prevent this all together, but i at least don't want it to be obvious.
View 4 RepliesHere is what I want:
1) a sprite with a rollover/out tween, going from alpha 0 to 1 on rollover, and back to 0 on rollout (let's call it "containerSprite"). That part is cake.
2) another sprite within the container (let's call it "closeButton"), that goes along for the ride (i.e., its alpha gets tweened along with the container). That's easy enough to do by making it a child of "container". When I say it is "within" the container I mean in terms of x/y.
3) when I move the mouse within containerSprite and onto closeButton, I want the container to stay visible (easy enough by setting mouseEnabled or mouseChildren to false). But I want closeButton to respond to mouseDown events, so I can't set it to mouseEnabled=false, nor can I set containerSprite.mouseChildren=false.
4) there will be several other sprites within the x/y of containerSprite, each with their own rollover/out tween. The catch is, when the mouse is within containerSprite and rolls onto one of them, the alpha of containerSprite SHOULD tween out (unlike when rolling onto closeButton).
For the life of me, I cannot get it all to work. I can get the desired behaviour in (4) easily enough, either by making the other sprites (mouseEnabled) children of containerSprite, or by making them siblings of containerSprite but higher in the display list. But the desired behaviour in (2) and (3) is vexing me: if closeButton is a child of containerSprite then its alpha tweens along with containerSprite (desired), but because it must be mouseEnabled, moving the cursor onto it triggers containerSprite's rollout event (undesired). If instead it is a higher sibling of containerSprite rather than a child, it has the same problem: if it is mouseEnabled, moving onto it counts as a rollOut event for the container. It seems like the solution ought to be easy, and I'm just missing something that is in plain sight.
I just started learning ActionScript 3.0/Flash CS5 a day or two ago, and I am still very early on with it, however I do have some other web development experience with PHP and some Javascript. I am learning from a book that was written for Flash CS4, but it did not seem like a whole bunch was different. I am now getting "Error #1009: Cannot access a property or method of a null object reference. at Main()"
I did several searches for the problem here, but most of the threads referencing this error are far more complex than what I am trying to do, involving multiple, long class files and the timeline. I have been unable to solve my problem after reading through various threads for hours now. Most of the fixes had to do with the timeline, however, all of my GUI is in one frame with no animation.

Its 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.
View 3 RepliesIs there an easy way to set a number in a function call?In C you'd just pass the pointer, but since AS3.0 has no pointers, I'm not sure what to do.I suppose I could create a class that wraps the Number to an Object, forcing AS to use the pointer, but that seems a bit clunky.
View 4 RepliesI started out with Swish, then I moved on to Flash8. I have quickly realized that it's a lot more difficult to achieve animation. Probably due to my lack of education with actionscript 2.0 and Flash8. Are there simple shortcuts to being able to do something as simple as making a photo spin around and explode? I haven't explored Flash8 much, but it doesn't seem as easy as Swish was. Of course, Swish seems obsolete compared to more advanced flash programs.

I thought to create a custom component which extends the s:Button and set there buttonMode to true but I wonder if there is an easier way like with CSS.
I try to save some variable in a game with local Shared Object, that basically should go like this: after every completed level it sets the variable to that number of level (if not higher already); then i have a MC that reacts to that variable (set its frame number to the number in the variable) so you can select already completet levels.
Now i thought, this would be easier, and tried [not allowed link to some tech note from Adobe on local SO], but didn't worked so far.
I am in need for some 2D physics seen from "above and straight down". Basicly I can sum it up with a "throwing balls into walls" kinda physics.
There seem to be quite a few physic engines for as3 out there, but I wonder if anyone have anyone special to recommend regarding my particular need as well as performance of the engines.
I'm trying to create a simple top game. Except, the movement of toy tops isn't so simple.I've been able to get the top to trace out squashed loocking spirals. However, the motion isn't random and there's no object detection. I was thinking that some variation of a bouncing ball script might work. However, the movement would have to be confined to the appearance of a perspective plane (so that it looks like it is spinning on something flat)

I need help with one of my Flash projects,I'm trying to use gskinners shape based collision detection, but for some reason I cant get it to work, but im pretty new to using classes, so I dont understand the structure too much. Can i get a tutorial on how to use the gskinner class? im using the as2 version.heres the code, bare with me, there's a lot here. in all codes, mc1 is the track outline MC, and mc2 is the car
basicly im making a 2D top down version of WipEout HD Fury, so file structure is something like this (the .fla is called wipeout as3 because i was initialy coding in as3 and never changed the filename).wipeout as3.fla (the flash file containing all the MCs and animations, but only enough coding to import all of the external code files, as well as the VCam and its script)
the code is;
Code: Select all #include RaceControl.as"
the RaceControl.as is used to determine the Car's control scheme, and refers to a physics code called RaceCar.as. i found it on the interwebs, all credit to matt carpenter;
Code: Select all// Race control
// Create key listener[code]........
the Bounce Function is my own work, and is what i want to happen when a collision is detected.now, the movieclip used for the car is my own drawn design, as is the track, and i want to use GSkinner's shape based collision to detect the collisions properly. so far i have the car driving around quite happily but i need it to collide with the walls of the track, rather than drive right through them.
