ADOBE DIRECTOR BASICS
Asynchronous programming
A drag and drop operation starts with a mouseDown and ends when the mouse is released.
In the DragAndDrop.dir movie:
1 The operation starts when you click the And sprite. The on mouseDown() handler in the Drag and Drop behavior
initializes the operation and sets a property which is used to track the state of the operation.
2 As you drag the mouse pointer, the position of the And sprite is updated. Once, per frame, the on enterFrame()
handler moves the And sprite to the same position relative to the mouse.
3 When you release the mouse, the operation ends. As part of its action, the on enterFrame() handler checks if the
mouseDown property is TRUE. If it is not, the mouse is released by the user, and the mDrop() handler is called to
complete the operation.
Here is a simplified version of behavior that handles the Drag and Drop operation. It is attached to the sprite displaying
the word “And”.
