AS3

[arofa]

Is it possible in AS3 to have a left click mouse function to drag and holding control key + click to do something else?

Thank you,

Hi.

You can do something like this:

import flash.events.KeyboardEvent;
import flash.ui.Keyboard;
import flash.events.MouseEvent;
var ctrl:Boolean = false;
var mouseDown:Boolean = false;
function start():void
{
    stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseHandler);
    stage.addEventListener(MouseEvent.MOUSE_UP, mouseHandler);
    stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseHandler);
    stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
    stage.addEventListener(KeyboardEvent.KEY_UP, keyHandler);
}
function mouseHandler(e:MouseEvent):void
{
    if (e.type == MouseEvent.MOUSE_DOWN)
        mouseDown = true;
    else if (e.type == MouseEvent.MOUSE_UP)
        mouseDown = false;
    if (e.type == MouseEvent.MOUSE_MOVE)
    {
        if (ctrl && mouseDown)
            trace("ctrl + dragging");
    }
}
function keyHandler(e:KeyboardEvent):void
{
    if (e.type == KeyboardEvent.KEY_DOWN)
    {
        if (e.keyCode == Keyboard.CONTROL)
            ctrl = true;
    }
    else if (e.type == KeyboardEvent.KEY_UP)
    {
        if (e.keyCode == Keyboard.CONTROL)
            ctrl = false;
    }
}
start();

I hope it helps.

Excellent!

You're welcome!

I'm not sure if JC's idea will work out, but there is already a context menu system in place, since Flash 9. Here's the documentation:
