Draggable objects

This flash tutorial will teach you how to create draggable objects. This effect is very simple and will only require a few lines of code. For this tutorial I made a draggable chicken but you can create whatever you wish. I will be showing you how to make the draggable object itself, not the chicken object.

Create a draggable object

Step 1

Create a new flash document.

Step 2

Create your movable object on the stage. I made a chicken but you can create whatever you wish.
Convert your object into symbol by selecting F8.
Give your symbol an appropriate name and check the movie clip button then click ok.

Step 3

Using the selection tool (v) select your movie clip and give it an instance name eg. chicken_mc.

Step 4

On the timeline, add a new layer called "actions" then select the first frame of the action layer and press F9. This opens up the actions window.

Add the following code:

chicken_mc.onPress = function () {

chicken_mc.onRelease = function () {

**This piece of code is pretty self-explanatory when your draggable object is clicked by the mouse it starts the drag. And when it is released by the mouse it stops the drag.

Step 5

Test your draggable object Ctrl + Enter. Now use your mouse to click and drag and chicken.

You should now a nice draggable object.

how to make the chicken return automaticly to its original spot after dragging?

You have to set the x & y property of the chicken inside the onRelease function. So, you would get:

chicken_mc.onRelease = function () {
chicken_mc._x = (original spot);
chicken_mc._y = (original spot);

Hey this is a really fantastic tutorial and a massive help for me. Although I am having problems getting this particular mode to work, its giving the error: Scene 1, Layer 'actions', Frame 1, Line 5 1120: Access of undefined property on_boxlight. Do you know what i am doing wrong? it seems to be unable to detect it yet iv tried editing all its properties and checked it has the same names and all. P.S i get the error when running the preview.

Thanks in advance!

cool. how would you make the object stay in new place for next time you run flash movie?

To make the object go to a random location, you can do this

chicken_mc._x = Math.floor(Math.random() * Stage.width);
chicken_mc._y = Math.floor(Math.random() * Stage.height);

make sure you have the instance name:on_boxlight on the stage.

hi! Great tutorial, thank you!

I do have a question though. Is there any way to make the item draggable only from an area of said item? For instance in the above example, could you have it so the chicken was draggable by the beak only, and the rest was unclickable?

I suppose you could make a beak a movie clip inside the chicken movie clip and target the beak. e.g.

chicken_mc.beak_mc.onPress = function () {

ahh of course! I had created the movie clip within the object, but neglected to direct it to the object within... In other words, I had simply forgotten the chicken_mc. part of the required code.

Thanks again!
