ActionScript 2.0 :: Set A Bitmap To Follow An Object?
Dec 10, 2006
basically im trying to set a bitmap to follow an object i have.heres some code...
Code:
override public function paint():void{
super.paint();
if(imageLoaded=false){
trace("loading image...");
[code].....
all the stuff in the loadImage() used to be where loadImage is called and it would run but would draw the image over and over leaving a trail so i moved it so it would only draw once but now it wont even work, tells me "Error #1009: Cannot access a property or method of a null object reference." which reffers to "mBit.x = super.px;".
I know the topic of "duplicating" movieclips is a hot issue with the new virtual machine. Luckily, I understand the implications. I only am [currently] interested in duplicating a Bitmap. See, I load an image from an URL using 'flash.display.Loader.load', which is a non-blocking operation in Flash Player.However,I may use multiple copies of the loaded image (which is reported to be a Bitmap, naturally) in the display list at the same time.Hence, I naturally do not want to load the image from an URL every time, because I don't want to wait for a non-blocking call to complete. Nor do I need to - I mean one copy is already loaded, so it should be possible to just "duplicate" it, right?
My idea is to do use the bitmapData property of a Bitmap and pass it to the constructor of a new Bitmap object. I have not tried the following in action, but I want to hear whether any of you did and if the following would not work, what would:
Code:
var original_bitmap: Bitmap; var copy_of_original_bitmap: Bitmap = new Bitmap(original_bitmap.bitmapData);
LiveDocs mention that the BitmapData being passed to a Bitmap constructor is "being referenced", which to me might suggest it cannot be used twice? There is also the BitmapData::clone() method, which I am not sure is applicable here or not.I know this is a lot of talk instead of just trying this out, but I test so much Flash Player code daily just to see "what works" (which should be documented instead by Adobe),
I am currently trying to create an app using flash AIR.I would like to find some more information on how to make an object snap to another ojbect then follow its path, eg. a person object is already on the stage, then drag an arrow to the object which snaps to it, then on play button it follows the arrow path. all in pure actionscript, no guide layers.
I've been searching for a while but was unable to find an answer for my problem. In my document I have two objects -- one that is moving when using the keyboard arrows while the other one has to follow the first one and try to hit it. How do I make the second object approach the first one?
I am using CS3 and trying to get an object to follow the mouse and having a hard time finding a tutorial on this, because all of the ones i have found want me to add the actionscript to the MC, and my version of flash won't let me do that. Flash expects me to attach it to the frame and so the code doesn't work.
I have the script so that you can controle a car with the arrow keys but for one of the missions on my gta2 style game I would like an enemy car to follow you. The car has to stay facing the right way according to the way the street though, this is the only bit I cant think of I also need boundaries.
...without using the startDrag method. I know I can use code like this inside of a mouse event listener/function:
Code: objectMC.x=mouseX; objectMC.y=mouseY;
This code makes the object move with the mouse, but only if I move the mouse very slowly. When I move the mouse quickly, the mouse leaves the area of the object and thus the MOUSE_OVER listener stops listening, causing the object to stop.
I have this kind of menu structure design (see image attached), and the way It needs to work is when the mouse goes close to a topic it follows it and when the mouse is a certain distance away it springs back to its orginal place?
I need to beable to detect and object or movie and allow another object/movie to follow that the first object/move but only moving up and down ........ not on the x-axis.
I have a box that i made dragable by clicking at it. I would like a green line attached to a point in the frame and the other end of the line attached to the movieclip being dragged. Hope i made it clear lol.
How would i go about to achive this effect? If possible without having the line itself being within the dragable movieclip (because the dragable box is in more than one frame and i only want the line in one frame)
I continue in my adventure with customizing a horizontal slider's functions. This is the very last thing I need to figure out and it is done.I have posted an SWF at the following link so you can see it working: neterhetdotcom/test/slidermask/ (change "dot" to a period "." as i am not yet able to post links)If you click on the scrollbar. You will see that a mask follows the click and displays an "orange" color... this orange color is supposed to indicate the progress of the slider across the scroll bar. the mask is positioned just to the left of the slider on the click so it allows the "orange" color for "progress" of the slider to "show up".
If you click and hold on the slider the mask does not track this motion. I need to know how to make the mask track the mouse along with the slider. The mask would have to align it's right edge to the point of the mouse click for it to work as the mask is the same width and just slightly taller than the visual scrollbar. (a narrow rectangle as well)How the scrollbars is set up in Flash is I have 2 layers with the scrollbar art on each. the bottom one is the default greay "off" state.. the top one is the orange "progress" state that has a mask attached to it so when the mask slides the orange shows up or goes away. (Thus indicating the progress of the slider across and back)So either the mask has to follow the slider button (on the left edge of the slider button) or the mask has to follow along with the slider on the mousedown state...(as long as the mask had it's right edge aligned to the mouse click)
I need to get my character to follow an moving object. I've got an object that's moving around in different directions and I'm wondering how do I get my character to follow the movements when standing on the object ?
Say I am moving an object around on the stage, walking from point A to B across the stage. I want to make the object the center, so the stage is centered on the object, so when I walk from point A to B the stage moves with me.
I'm trying to trace the path of an object by using setPixel on the object's position every frame in a BitmapData/Bitmap pairing. These pixels aren't showing up normally and I suspect I have a fundamental misunderstanding of the BitmapData class. Here's what I'm doing:
public var contrailBase:BitmapData; public var contrail:Bitmap; private var contrailColor:uint;[code].....
Using this code, the red pixels don't show up. If I initialize contrailBase to 0xFF000000 instead then I get a black screen on which the red pixels DO draw, but I need the bitmap to be transparent except for the contrail. What am I doing wrong?
I cannot find how to have an object follow the mouse at a CONSTANT speed. The code I keep on finding is something like this:[code]I don't know if I'm just missing some really simple detail, or some major idea, but I'm pretty sure something as easy as this is possible.
im trying to make my plane movieclip follow the mouse... which i have achieved although i want to give it a regestration point so that when the mouse turns or goes left, right, back etc, the front of the plane goes with it so it looks realistic aposed to a plane image moving left and right.
make my hero go back to his shelter when he finds some food or when he approaches an enemy. It looks like this:
1. The hero is in the shelter. 2. The hero is hungry. 3. The hero leaves the base to hunt some animals down. 4. The hero is full and is headed back to the shelter. 5. He moves in the direction of where the base is.
So, once again, how do I make my hero go back to where he came from? How do I make my hero's x and y position to fit the way back home?
I'm making a flash page with a basket movie clip that follows my mouse. The basket has a stop action on frame one so it stays there unless directed otherwise. Then I have a movie clip of a green berry that I made into a button (titled gb1). I need to make it so that when that is clicked it makes the basket go to the next frame (numbers change to show how many berries were collected). Here is my (unsuccessful) code as of now.
//1. stage.addEventListener(Event.ENTER_FRAME,followBas ket); //2. function followBasket(event:Event):void { var dx:int = basket.x - mouseX;
I am using Flash 8 and AS2. I have been looking and looking, but I cannot find how to have an object follow the mouse at a Constant speed. The code I keep on finding is something like this: Code: onClipEvent (load) { _x = 0; _y = 0; speed = 5; } onClipEvent (enterFrame) { endX = _root._xmouse; endY = _root._ymouse; _x += (endX-_x)/speed; _y += (endY-_y)/speed; } The "/speed" part makes the object move slower the closer it gets.
i am trying to make flash for website where many smileys are there on the screen and they follow the mouse at varying speed.now when i rollover to any smiley it should display a speech bubble with dynamic text..the problem is in the rollover..it does not stop there but keeps moving so speech bubble disappears very fast.im attaching the fla.
I am making my second flash game, I am still very much a beginner. This time i am trying to make a platformer in the style of fancy pants adventure. To do this i obviously need to make the camera follow my character. The problem is; i simply don't know how. I have yet to find a CS5 compatible solution with my less than good google skills, and so here I am.
I am trying to get a stationary object to follow the mouse but remain in its location. Example: i am trying to get the center of a compass to follow the mouse around screen while remaining inside the compass. i have only found out how to have it chase the mouse but not remain on a fixed point and rotate.

I found this tutorial [URL] and is wondering if I could limit the area where the clip can follow? I'm planning to have my cartoon's EYEBALLS follow the mouse move.
I've got another simple question. I have a mc who's bitmap that is associated with him I want to change.
[Code]...
When BlankClip is first created, I want to tell it to either have the same image as Block_0 or Block_1. Looking it up online, it seems like I have to use BitmapData somehow, but I'm really unfamiliar with things...I've been working on this same code for about 2 hours...
How would I be able to create a scene where you scroll left to right using the mouse, but instead of having it at a constant rate and having the picture (background) move when your mouse is at a certain x coordinate to have it be that when you move the mouse away from an object the background will move, and will move faster the farther away the mouse is? I have tried scrolling back and forth with x coordinates, but I haven't been able to get this to work.
(I found an example of what I'm trying to describe here; [URL], just click play, skip, leave, and then leave again and you'll be able to see it).
