Professional :: How To Code A Drag & Pan Feature
Aug 12, 2010
I'm making a map with Adobe Flash Professional CS5, using Actionscript 1 & 2, and I'm trying to add the ability to drag and pan while zoomed in. For the zooming, I put a button in either corner: a zoom out icon, and a zoom in icon. For the zoom-in icon, I used the code on (rollOver){ setProperty ("BG", _xscale, "200"); setProperty ("BG", _yscale, "200");} (BG being the name of the instance used for the background of the map, which is a movie clip.) Now, this zooms me in well to one corner, but then i want to be able to drag and pan to be able to see more of the map. I've found some good examples, but the code is way over my newbie head, and I can't get any examples of code I find to work, no matter what I've tried.

I need to finish this code, the remove child works and removes the character mc, but I want to remove a fair few event listeners, so I can implement a drag and drop feature. My problem is would I need to list all the listeners to stop them on this frame? And this should only effect the listed listeners and not the new code for the drag and drop?
Code:
this.removeChild(char);
this.removeEventListener( Event.ENTER_FRAME, EnterFrame )

how to output the error messages I'm seeing in my output screen in the IDE to a text area, so I can see if such errors are occurring in production What I found is that the forum search feature is not working at all. I received no results for the words "error", "movie", "flash" and "text", items which are obviously ones which should return SOME results.I couldn't find any way to contact Adobe about this, so I am hoping someone who works for Adobe and watches the forums will pass this along.

I started an animation in flash recently and the autosave feature was turned on. I had a good animation, but decided to play around with it a bit. After a little while, I decided to call it a night and exited the program making sure NOT to save my work. Upon opening that file the next time, I come to find out that Flash has autosaved my file while I was playing around. Now I have a worthless animation, and have to start from scratch. Is there any way to revert to a previous save, or autosave at this point, or am I about to do a lot of work again?

Please provide the feature to disable the system screensaver & power saving features while a video object is currently playing a video. I get this request all the time when developing video players and now that the netflix player provides this feature it is becoming a must have in the online video market. If you know other solution which does not require .net, silverlight , or any other browser plugin besides flash please let me know.

I have some code that is canceling out my other code. I have code that is controlling two movie clips. Below i have the code separated in two sections, marked my comments. When i add the second sections "//info box", it disables the code above it. I know the code works, because i have it working separatly. Can anyone tell me what the conflict is?

I have found the following code and modified it.
Code:
// Drag a piece of garbage.
rubbish_mc.onPress = function() {
this.startDrag(false); }; // When the garbage is dragged over the trashcan, make it invisible.
rubbish_mc.onRelease = function() {
this.stopDrag(); // Convert the slash notation to dot notation using eval.
if (eval(this._droptarget) == trash_mc) {
rubbish_mc._visible = false;
change_score(); } };
My question: I have numerous movie clips for the rubbish. Is there a more elegant way of calling them than repeating the above lines with rubbish2_mc, rubbish3_mc etc.

I would imagine it's a simple enough bit of additional code, but I'm no programmer, and trawling the Web has proved fruitless to date...ithin Flash CS5 and using AS 3, I'm attempting to create a series of drag-and-drop interactions for a learning exercise where items must be dragged into the correct box with positive and negative feedback being generated as a result of where the learner drops the item. All I need is the code to link the drag and drop code snippet (which I have working) to a specific object/location on the stage (which I cannot find nor figure out for the life of me)

I got my Drag n drop working. Now I've added a timer. I want the students to have 45 seconds to finsih the game. I can code a timer OK, I can even get it to jump to a "time's up" frame, with a restart button that takes you back to where intro page for the drag n drop.If you click one of the two visible navigation btns on the d'n'd page BEFORE the timer has stopped, you get an error.I have no idea how to stop the timer as a result of fishing the d'n'd game within the time limit (i.e. correctly placing 12 pegs). As it is, you finish the game, one text field says "Congrats!" (which is good) but you still get tmed out (which is bad).inal step in my little prototype edu app.Here's the salient part of the code (I think) and I have removed all the code that comes after the important part:
var counter:Number = 0;
var startX:Number;
var startY:Number;

I'm trying to make a basic card game where I can flip the cards and also drag them around. Here's the code for card.as, the file that's controlling my cards.
package{ import flash.display.MovieClip;
import flash.events.MouseEvent;
public class Card extends MovieClip { private var _type:*;
public function Card() { this.buttonMode = true;
this.addEventListener(MouseEvent.CLICK, onClick);
} private function onClick(event:MouseEvent):void { this.play();
} public function setType(type:*):void { _type = type;
loader_mc.addChild(_type); }}}
I've been trying to add draggability to the card, but I'm not sure how to do it. Do I need a separate ".as" file to control it? Or, do I build it right into this file? If so, how would I do that? I tried making a separate ".as" file but then my basic card flipping code doesn't work.

Would like to develop simple (in browser) puzzle games where shapes (such as a puzzle piece shape) can be simultaneously dragged and rotated, then dropped on the screen or canvas. The game mode would be to click and drag the shape or object, while simultaneously rotating the piece using arrow keys Is this possible in Flash? This simple general activity of simultaneous drag and rotate, then drop, is my intended overallweb site game basis. I'm new to Flash but have developed Windows executables for many years. I'm trying to decide whether to purchase and learn Flash as platform for interactive educational puzzle games running in browser windows.

Im trying to create a simple drag and drop app where you can drap a movieclip into multiple areas.This is the code i have so far (taken from a tutorial i found) thats works perfectly for 1 target but not for multiples. I initially tried giving the targets the same instance name but that didnt work.
stop();var startX:Number;var startY:Number;
square_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);square_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
function pickUp(event:MouseEvent):void { square_mc.gotoAndStop (2); event.target.startDrag(true);

I've built a drag and drop project with 9 elements in Flash CS5 using AS 3.0. Using code from an AS3.0 4 element drg&drp tutorial (which worked) I copy/pasted the code into the new project, renamed graphics in AS where necessary and added the additional code required to accomodate the additional graphics.When playing the test I get no errors however the first logo (element) and it's invisable target just flash on and off 11 times, then I see a frame of the whole project (for 1 frame) and then the cycle repeats.
I've double checked all naming conventions and everything is correct between movie clips and code. I've even simplified the code to just 1 element to see if I could track down where the problem starts and I get the same thing. The strange thing (to me anyway) is if I change the name of element to be dragged/dropped (in the code) to a different element on the stage I still get same original graphic flashing. So I don't think it's the code at all I think there is some weirdness in the graphic setup.

I'm trying to adapt the memory game in chapter 3 of the book "ActionScript 3.0 Game Programming University" for my own uses. I want to get all of the cards to flip and drag. I am able to flip the first card and drag it, but when I flip the second card over, I can't drag it. I have two files, MatchingGameMe.fla and MatchingGameMe.as. All of the actionscript is in MatchingGameMe.as. Here is the code. Does anyone see how I can modify it so that all the cards drag?[code]

Stuck on this big time. Using as2. I have a draggeable record. I want a button on the record that when I hit it, it plays a sound. I've attached the source. I've tried a few different tests and I've figured out that the onpress action of the main mc itself I believe acts for the mc of the speaker. I want the record draggable but need to have the speaker activate if i hit it.[URL]..
