ActionScript 3.0 :: Dragging With Inertia For Dummies?
Jul 1, 2010
I'm trying to achieve a fairly simple effect--a dragging a MC with inertia.
Specifically, I'm trying to get this to happen:
1. When you click with the mouse on the MC (not the entire stage), the MC gets dragged along.
2. When you let go of the mouse button, the MC keeps going with inertia (slowly comes to a stop) that depends on the speed with which the MC was dragged and in the same direction. The MC shouldn't change directions if the unpressed mouse is moved around.
How would I convert a point in the longitude & latitude to x and y (pixels) on a mercator-projected map, assuming I know the exact dimensions of the map (by longitude/latitude, and pixels)?
*Someone* has had to have created a class that handles such relatively basic and essential (not for me, unfortunately!) math; remapping a point, measuring the distances, etc.
Any tips? I've read some formulas (including the one here: [URL], but I admit that my math is quite poor at this level, and I've got no idea how to convert such a thing to AS, nor if there are other considerations I'm missing.
I want to make a 3d carrousel, classic stuff. I won't be able to explain what i want so i uploaded 2 pictures. The first picture attached is what you can usually see and the second one is the effect i want...a little bit more 3d. Hope you'll understand what i mean. For now here's the code i use onEnterFrame :
I've been trying to make a scroller, but the movieclip IS the scroller (if that makes sense?)So I have a movieclip that's, say, 1920 wide, and the stage just resizes to the browser, and when you drag the movieclip it scrolls. I have this semi-working but it's quite buggy on resize, and i also want inertia on the movieclip when it moves.
i've spent lots of hours looking up the internet trying many techniques but nothing do.i just want to add inertia to my car.
var car:Car = new Car(); var power = 10; addChild(car); car.x = 470; car.y = 200; var dx = 0; var dy = 0; stage.addEventListener(KeyboardEvent.KEY_DOWN, keyhandler); function keyhandler(event:KeyboardEvent):void { switch(event.keyCode)[code].............
You know the effect when you drag an object and then when you let go it continues to move but slowing down. I'd like to do this to my movieclips can someone show me how?
how could i modify this script so that it has inertia, and so that i can movie diagonally? is there a better way of doing mc movement with keypresses?[code]
how to make a scrolling text box with inertia...I know there are many out there but the problem is the only ones I can find have inertia applied after you lift your finger off the button...which leads to jerky movement if you are scrolling a small section. The desired effect is like the scrolling text boxes used in www.fontsforflash.com.(they have developed a component...not good if you want to customize the look of the scroll bar) [URL].... provides an open source version of this movie clip but it again is not so easily customizable.There has got to be someone talented enough to do this and provide a tutorial for the rest of us..
I want to imitate the iPhone scroll behavior in a Flash app I am developing. The idea is to enable drag-drop with a certain amount of inertia/deceleration (you know, when you drop something while your cursor is still moving and the thing would continue moving for a moment and then stop).
This code is a looped onRollOver, sa long as the mouse cursor is within "up", the movieClip moves up 3 pix at a time. I need it to slow down simulating inertia when the cursor is removed.I know a code that usually works.
f=0.3; xdest = 300; onEnterFrame = function () {[code].....
Does anybody know how I could make a MC keep moving a certain amount when I let go after dragging it. I want the distance it goes to be based upon how quick I moved the mouse before I let it go.
When you click and drag with the mouse, it gets dragged along, constrained to the x axis (left and right only).When the mouse button is the released the object keeps going at that speed and direction, the slows to a stop. If the unpressed mouse is the moved, the object DOES NOT change direction to follow the mouse.The object does not respond to or in any way follow the unpressed mouse; all it does it come to a stop when the mouse is released, as described above.
I've got a clip which gets multiple clips attached dynamically.I'd like to make it scroll up or down based on user mousing over it and mouse position. I want it to ease and to increase in speed if the user mouses further up or down.[code]
I need to familiarize myself with this technology. My problem is that Google is swamp with results for tutorials. Where should I start? What development environment should I use assuming this is only for learning purposes and I don't want at the moment to buy any expensive software?
I want to if I can set a variable with the mc's name that the mc I'm dragging around hits.I did this before with eval() in as2 but there is not such a thing anymore. [code]...
I am looking for a way to "drag" several movieclips at a time and thereby create a panning effect on the entire stage. The movieclips are supposed to follow the cursor (a mask) on the X axis.
I can start dragging the symbol no problem but no amount of clicking will get it to stop. Am I doing something wrong? Using Flash CS4 with ActionScript 3.
so I am trying to drag around some images in a canvas. I am adding eventlisteners to the components and calling startDrag() and stopDrag() to pick them up and stuff:
The problem is that it is selecting the image at its (0,0) location and not where I initially click on it. So there's a sudden "jump" when I click on the image. It is not smooth.
I noticed that startDrag() has two default parameters, one of them is lockCenter and it is default to false. Maybe do I set it equal to true somehow? (I don't know how to pass arguments to my second parameter in addeventlistener)
Another question: if I want to add more conditions to it, like make a new function that uses component.startDrag(), how do I pass the component to this function while adding event listener to it at the same time? for example: I want to do:
I have a flash project with three non overlapping panels (visual spaces) each of which contains different movie-clips. Each movie-clip in a particular panel is the child of that panel.Now, I want to drag one of the movie-clips from one panel to another (remove it as a child from the first panel and add it to the other) without a jitter and proper drag.What is the appropriate way to handle the drag architecturally
I have a movieclip in the centre of a cross and want to make it move only along the lines of that cross. Is this possible with startDrag or do I need more complicated method? To illustrate: If you've moved left or right, you can't move up or down and vice versa.
