I just made a custom cursor using this code:
function initializeGame():void
{
cursor = new Cursor();
addChild(cursor);
cursor.enabled = false;
Mouse.hide();
stage.addEventListener(MouseEvent.MOUSE_MOVE, dragCursor);
}
function dragCursor(event:MouseEvent):void
{
cursor.x = this.mouseX;
cursor.y = this.mouseY;
}
initializeGame();
The anchor point is registered in the top left hand corner. The problem that I am having is that the cursor is very laggy. My custom cursor contains no animation, it is just a cross hair. Is there any way to make it move faster like a regular cursor?
There is. You should update the screen (make a redraw) upon every mouse move. Add this to your mouse move listener:
event.updateAfterEvent();
There is a much better way to use custom cursors, check this tutorial -
Working with native mouse cursors in Flash Player 10.2
try using Event.ENTER_FRAME instead of MouseEvent.MOUSE_MOVE if possible. I did it and it made speed much better

I tried using the event dispatch but unable to get clear view of this one, so tell me if anyone know this.
This is Sample Code but i can't understand could you explain elaborate.
var ball:Shape = new Shape();
ball.graphics.beginFill(0xFF0000);
ball.graphics.drawCircle(0, 0, 30);
ball.graphics.endFill();
addChild(ball);
stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveListener);
addEventListener("myCustomEvent", myCustomEventListener);
function mouseMoveListener(event:MouseEvent):void
{
dispatchEvent(new Event("myCustomEvent"));
}
function myCustomEventListener(event:Event):void
{
ball.x = stage.mouseX;
ball.y = stage.mouseY;
}
Think about stage as a big box where magic happens. Stage knows when you resize it, when you press keyboard buttons or when you move mouse on top of it. It does extend EventDispatcher which means it can broadcast stuff (and it does!). You usually don't pay attention to it, but in this particular piece of code you have:
stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseMoveListener);
function mouseMoveListener(event:MouseEvent):void
{
dispatchEvent(new Event("myCustomEvent"));
}
What's going on in here? You're curious about MOUSE_MOVE event and that's why you add listener. Now every time you move your mouse over the stage, stage is going to broadcast (dispatch) event (like : "HEY! Mouse just moved!"). And every time that happens your mouseMoveListener would be called. You can add trace(stage.mouseX, stage.mouseY); inside it and it would trace your mouse position as you move it. You could also move this code
ball.x = stage.mouseX;
ball.y = stage.mouseY;
to that function and your ball would follow mouse cursor.
However what you're doing is:
dispatchEvent(new Event("myCustomEvent"));
Which basically means that you're broadcasting (dispatching) an event now. What event? "myCustomEvent". Now anyone who is interested might listen for it. And somebody is indeed:
addEventListener("myCustomEvent", myCustomEventListener);
function myCustomEventListener(event:Event):void
{
ball.x = stage.mouseX;
ball.y = stage.mouseY;
}
So you're basically listening for this even in the same class and when this even it being dispatched you execute myCustomEventListener function.
Hope that's gonna make it a bit more clearer for you :)
On my stage I have several DisplayObjects. To some of them I have applied a MouseOver functions.
These functions are primarily like this:
this.addEventListener(MouseEvent.MOUSE_OVER, hoverHandler);
private function hoverHandler(evt:MouseEvent):void
{
this.alpha = 2 * this.alpha;
this.addEventListener(MouseEvent.MOUSE_OUT, awayHandler);
}
private function awayHandler(evt:MouseEvent):void
{
this.alpha = this.alpha / 2;
}
This works fine until some of my moving sprites suddenly also is above one of the sprites I have applied Mouseover functions to. Then my MouseOver-function can no longer detect if the mouse is on the sprite.
This is rather disturbing for the usability of my code. Does anyone know how to avoid this?
Thank you!
You can set mouseEnabled and mouseChildren of the Sprites getting in the way to false:
aboveSprite.mouseEnabled = false;
aboveSprite.mouseChildren = false;
Use somethng like:
mc_1.hitTestObject(mc_2);
to determine an overlap. Then discover which MovieClip is 'above' the other with something like
parent.getChildIndex(this)
Then use mouseEnabled = false to de-sensitize the MovieClip that you don't want to respond.
Your exact code may vary somewhat depending on the setup.
In my application i have a mouse cursor which is attached to the mouse. However it will not let me click on buttons within my application which is a big problem for me as buttons are essential in what i need to do.
I am new to AS so any help would be much appreciated!
stage.addEventListener(MouseEvent.MOUSE_MOVE, draw_cursor);
stage.addEventListener(Event.MOUSE_LEAVE, hide_cursor);
Mouse.hide();
function draw_cursor(event:MouseEvent):void
{
my_cursor_mc.visible = true;
my_cursor_mc.x = event.stageX;
my_cursor_mc.y = event.stageY;
}
function hide_cursor(event:Event):void
{
my_cursor_mc.visible=false;
}
i tried using this (below) but was very glichy and had to press button for cursor to go away THEN i was able to click on the button (not really ideal):
stage.addEventListener(MouseEvent.CLICK, hide_cursor);
Sounds like your cursor might be stealing the mouse events for your buttons. In your top level code (or constructor) try adding:
// Disable mouse events for cursor
my_cursor_mc.mouseEnabled = false;
If you mouse event has any child objects also add:
// Disable mouse events for any children of the cursor
my_cursor_mc.mouseChildren = false;
I am making a game which uses collision detection with the mouse.
The player is a custom mouse cursor when the mouse collies with an object the mouse is moved to the coordinates X0,Y0. The code I have used to achieve this is below. However when the mouse is moved to X0,Y0 after a collision when the mouse is moved it starts back where the collision took place rather than moving from the top of the screen.
import flash.events.Event;
var cursor:MovieClip;
function initializeMovie ():void {
cursor = new Cursor();
addChild (cursor);
cursor.enabled = false;
Mouse.hide ();
stage.addEventListener (MouseEvent.MOUSE_MOVE, dragCursor);
}
function dragCursor (event:MouseEvent):void{
cursor.x = this.mouseX;
cursor.y = this.mouseY;
}
initializeMovie ();
this.addEventListener( Event.ENTER_FRAME, handleCollision)
function handleCollision( e:Event ):void{
if(cursor.hitTestObject( wall )){
cursor.x = 0
cursor.y = 0
}
}
Create a button at the 0, 0 coord that is required to click to continue again. Then your user will have to move the mouse to to that spot where you can continue to have the custom cursor track your mouse.
When you reset the position of cursor object you aren't moving the actual mouse position, I don't believe you can actual do what you're trying to (that is write to the mouse position to move the users cursor, I believe this would require system specific code, like C# or I believe Objective C and Cocoa or Carbon on the Mac side).

Here's a way you would do it on Mac apparently
https://developer.apple.com/library/mac/documentation/GraphicsImaging/Reference/Quartz_Services_Ref/Reference/reference.html#//apple_ref/c/func/CGWarpMouseCursorPosition
And a way on Windows
Set Mouseposition in WPF
And a way on Linux (Although this only has AIR support up to 2.6)
How to set the mouse position under X11 (linux desktop)?
So if you implemented both of those solutions and are packaging as an AIR app you could make this work, but otherwise I'm pretty sure it's impossible.
This morning I stumbled to this question:
When hovering a button, is it possible to click it automatically after X seconds? So the user doesn't need to click it with his mouse?
How can I let Flash believe my mouse really clicked some button on the stage or brought up with as3?
I have a lot of buttons in my movie. So I prefer to use some code which will cover this function for all existing or coming up buttons in my movie.
I would normally use a code like this but is there some workaround to accomplish this in a different way? I do no want to add code to every button.
this.addEventListener(MouseEvent.OVER, onMouseClickEvent);
public function onMouseClickEvent(event:Event)
{
trace(event);
if(event.buttonDown) // if button goes down normally
trace("MOUSE CLICKED NORMALLY");
else
trace("left button was not down");
}
The easiest way i think, is to subclass Button.
Then you should add mouse over/out listeners, add click listener that looks like that
:public function clickListener(event:MouseEvent = null){...}
When the mouse is hovering, raise a flag that the mouse is on the object, start a timer and when the timer callback function is called, you check the if the flag (you turn the flag down, when the mouse is out) is true and just call clickListener()
Listen for MouseEvent.MOUSE_OVER and start a timer, at the end of which the button will send the MouseEvent.CLICK event. In the mouseover handler, use the SystemManager to add a listener for MouseEvent.MOUSE_OUT which cancels the timer. The timer removes the listener using the SystemManager as well. So does clicking the button.
Finally! Solved!
This did the trick:
public function runOnce(event:TimerEvent):void {
btnSignal.dispatch("KEYBOARD", btnCode);
}
Robusto & Radoslav Georgiev: Thank you for pointing the right direction!
(I'm answering this a little late but would like to give input for future people).
One way to 'skin this cat' is to simply let your hover event trigger a timer (i.e. 3 seconds). In an EnterFrame or other function let a number or Boolean change when 3 seconds is reached.
//Pseudo code
if(timer == 3)
{ numberVar = 1;
//or
BooleanVar = True;
}
else
{
numberVar = 0;
//or
BooleanVar = false;
}
//end
Then just as you connected your methods to a mouseEvent, connect those same methods to fire when numberVar == 1 or BooleanVar == True. That's it.
For super simplicity and readability let your MouseClickEvent just be numberVar = 1 or BooleanVar = True.
These become super simple to implement over time and in my experience are 'very' error proof. Easy to fix also in the case of a typo or something else. No super elusive imports either. Hope that helped.
Great question by the way (+ 1)
