I am playing around with ActionScript 3 and trying to build a very simple prototype for a video game (top-down action/shooter) and realized that handling bullets is a little bit more challenging than I originally imagined.
In order to get a fairly decent "flight" of the bullet between the character and the target, I ended up using a highly modified version of Bresenham's Line Algorithm to determine the flight path of the bullet and then merely draw a tiny flash.geom.Rectangle object at the appropriate place on that "flight path" during the draw-frame stage of my application.
I haven't noticed any real problems, but I just can't imagine this being the best way to handle bullets in a Flash game. I imagine that once there are multiple enemy players on the screen and lots of bullets flying around (especially once I code in automatic weapons) that things could come grinding to a halt.
What am I missing here? I'm not really a game developer and so most of the things I'm doing I've just "made up" on the spot, but I can't figure out how to effectively handle bullets in Flash.
EDIT: As requested, here is "my" Bresenham code. I say "my" in quotes, because I basically ripped this from somewhere on the internet. My changes to the algorithm basically involve the lines at the bottom. The original implementation would find the path from player character to the target, except that every once in a while (and I wasted a little bit of time trying to figure this out but never got anywhere) it will generate the path from the target to the player. To "fix" this, I ended up just checking the first X/Y values from the path array and reversing the array if those values didn't match the X/Y values of my player character.
I'm currently making my own shoot'em up game where the player can switch between two player types which will fire their own bullet type in this case, squares and circles. I've setup the player switch function via pressing "space" button (switching between the two player types) and the default bullet type is "squares" and I'm not sure to approach the coding with changing the bullet type to "circles".I've written 2 classes for the bullet and player setup:Player Class: Creates instance of bullet on screen and enables the switch player type function
Bullet Class: Enables bullet properies and bullet types Player Class: Code:function onKeyDown(event:KeyboardEvent):void {if (event.keyCode == 32) //// pressing/holding "space bar" to function
I'm trying to make my platform game character shoot a gun, my character and gun are one movieclip and the bullet is another. The bullet mc starts on a blank frame with a stop() function, when I press the space bar the bullet mc plays from frame 2 which is a motion tween of the bullet quickly moving across the page. I've set the bullet's y and x values relative to the character mc so that the bullet always comes from the gun.
My issue is that if I press the space bar a bullet will fly out of the gun (great!) but if I press the space bar again, the first bullet disappears and the bullet animation starts again. I want to be able to shoot a new bullet every time I press the space bar without effecting the bullets that have already been shot.
I am working on a Flash game that uses 2D polygon collision. It seems to me that I could sketch the 2D collision around my objects using the pen tool, and make it invisible by putting it on a separate guide layer.
how to access the data on that layer - preferably as a set of points - from ActionScript.
How do I actually remove the full path as in C:program filesappfilename.jpg so that the only left is filename.jpg? Substr or Substring can be use in this case to remove after detecting the first occurrence or / by looping from the string end position.
i have 2 classes, one for ship one for bullet.i was trying to set the bullet.x to ship.x in the bullet class but it keeps telling me undefined. but clearly it is in my ship class.
the same class is passed to the mxmlc compiler in SWF library as a symbol linkage class and again in a source-path. But the compiler uses the definition from the source-path so creating new instance of that class won't create new instance of the library symbol. How do I tell the compiler to prefer the definition linked to the symbol (the one dfrom SWC)?
I have my design assets in an FLA file and they are linked to classes (e.g. [URL]. Then I export those assets to a SWC library and pass it to the compiler. Now when I create an instance of the class (new MyAsset();) it will be a new instance of the library object.
But there are other classes too in the source folder (e.g. "com.myproject.model.*" so I need to pass the source folder to the compiler too. And that is the problem, now the compiler will use the MyAsset.as definition from the source path, not from the SWC where it is assigned to the library object so if I create new instance of MyAsset now it won't duplicate the library object.
Im trying to add an exit button onto my program so when its clicked it exits the program completely.. I've tried some of the suggestions on the forums but they arnt working. what I have been using and its not working..
// CLICK to Exit exit_Btn.addEventListener("mouseUp", goExit); function goExit(evt:MouseEvent) { fscommand("quit"); };
My goal is to shoot a bullet everytime I click on ship. What happens, in fact, is that If I click on it once, the bullet is shot, but if I click on it twice before the first bullet is off the screen, the first bullet literally stops(it does not disappear, only stops) and the second bullet is shot.
public var ship:Ship = new Ship(); public var bullet:Bullet = new Bullet(); stage.addChild(ship);[code]...
I need to program a timer for a typing tutorial program. It needs to go to 5 minutes. When the timer gets to 5 minutes the movie has to go to frame 13 which displays the results of the typing test.
So I've created a script where a mc is clicked on and the player can draw a path using the mouse. I'm trying to figure out how I can get the mc to follow the path drawn out by the player's mouse and when the player clicks again, it erases all of the path.my code is below
I have created a flash program and I would like to run a second flash program from inside the first. To explain, say I am running a program that draws a circle and fills it with a color. Then, I have designed a second program that will divide a circle into sectors by entering percentages, to turn that circle into a pie chart. Is there a way to be running the "draw a circle" program and have a button that opens the "divide the circle into sectors" program in a new window and then passes information from that program to the first program. I am sure I will have to send the information from the second program to an XML file and then have the first program recieve it from the XML file (which I can do), but I don't know if I can run the second program from inside the first program.
I am creating a tower defense game and I want to make a tower that shoots a bullet and every enemy that the bullet hits is damaged. The bullet can hurt multiple units. My problem is detecting if the bullet hits the enemies. Right now, I have the enemies in an array. With other towers, when an enemy is in range, the tower fires and when it hits its original target, it causes damage to that target.
For the tower I want to make, it will shoot the bullet the maximum range every time and I need it to damage every unit it hits on the way to that final destination.
I am new to Flash and ActionScript 3.0 environment. I don't have any knowledge in depth with Flash and ActionScript 3.0. I am using the flash(.swf file) in my Java application. Now, this .swf file is to be placed in the server system. While I am working with these, I faced an error. Here, my issue/problem(s) starts....
1.)With the help of URLRequest & URLLoader classes, I am loading a jpg file dynamically onto the stage using the following code:
I was wondering if it possible to write up some AS that will take line paths that you have drawn and convert them into a Path object? For example say you drew a jagged line from left to write, would there be a way to have AS convert that into a Path object.
I'm trying to set up a collision so that when a bullet hits a wall it is destroyed. Here is the snippet of code I am using: PHP Code:
[Code]...
This method works great for when detecting a collision between other moving instances and the walls, but for some reason with the bullets I get this error message when they almost touch the wall and Flash freezes and I usually have to restart it: PHP Code:
I am displaying some flash content on a fairly standard page. This works really well when the flash, xml file and html page are sitting together in the same directory.url...However, I want to display that same content in another page which is deeper inside the site but outside of the directory that houses the .swf and .xml files as well as the assets.[code]The js files are loading properly but the flash content is not, so I could use a little help getting that sorted out.
I've been working with Flash for over 3 years, but I can't figure this one out. I've got a body of text, half of which are bulleted points designated by <li></li>. It's loaded into a html-ised dynamic textbox.
[Code]....
It displays fine as is. However, if I make the box selectable, and select any part of the bulleted list, the ENTIRE body of text turns into a giant bulleted list, including the non-bulleted portion at the beginning. I've managed to replicate this bug with Flash 8 and CS3, using a variety of flas made from scratch.
But the problem is that the car is moving when you controll it so the bullet stays on the same position and I want it to follow the car and start from the same position as the car whereever it goes.
I'm creating a small car game where you shoot from the car, so I've made a bullet animation with this code inside the mocieclip:
shellNo = 0; function shellEject(){ shell_holder.attachMovie("shellAnim", shellNo, shellNo); shellNo++; }
But the problem is that the car is moving when you controll it so the bullet stays on the same position and I want it to follow the car and start from the side of it whereever it goes.

Basically i just need a simple way to remove the "Enemy" when it comes into contact with "bullet".Ive been looking on the internet but its just really confusing me at the moment. And im not sure how easy its gonna be with the way i have set it up.
