Essentially I'm just trying to rotate an object (mc) clockwise or anticlockwise depending on the value of a variable called 'angle'.If 'angle' is positive it should go anticlockwise.If 'angle' is negative it should go clockwise.
Option 1
PHP Code:
if(angle > 0) {
mc.rotation += rotateIncrement;
}
[code]....
i would like spin an object in clockwise and anticlockwise direction with ease via press of a button.tried using,
on (press) {
this.testmovieclip._rotation += 45;
}
just to get the object to turn... What i wanna do is have 4 buttons, 1st button turns the object 45 degrees, then 2nd button turns it next 45 degrees and so on... Have attached .fla of what im trying to achieve.
I am sure this is simple, but cannot remember how it is done. I just need to rotate an item counter clockwise 1/2 a time. The rotate option only accepts integers and when I do a motion tween it goes clockwise.
View 1 RepliesI have 2 movieclips. ro used for rotating and rect the movie that will be rotated.
I want when clicking and draging the ro movieclip clockwise or counterclockwise, the rect movieclip is rotated clockwise or counterclockwise respectively.
I allow the rect to be rotated according to mouseX and mouseY.
but it dose not work as I need.
I'd like you to show me a trick to achieve that as I want.
Here is the code:
var xPo:Number;
var yPo:Number;
ro.addEventListener(MouseEvent.MOUSE_DOWN, mouse_down)
function mouse_down(e:MouseEvent):void

I have a movieclip called view_mc and a button btn_rotate.
I want when the user click and drag btn_rotate button, he can rotate the view_mc movieclip clockwise and anti-clockwise.
I have written a code, but it only rotates the movieclip in clockwise direction:
stage.addEventListener(MouseEvent.MOUSE_DOWN, on_stage_down);
stage.addEventListener(MouseEvent.MOUSE_UP, on_stage_up);
function on_stage_down(e:MouseEvent):void

I'm writing a class for an instrment and one of the knobs has "snapping" values at X degrees.I have the code to make the knob snap to the set degrees,but I'm having trouble getting it to determine whether it was rotated clockwise or counter-clockwise.Here is the function that makes it rotate and "snap" The majority of the problem is because of the 0/360 and negative values that Flash has when it rotates..
In the function:
the _baseMovieClip is the clip that contains a graphic to rotate and "snap" to the degrees.
the _clipToRotate is a movie clip that actually displays the rotation
the _startAngle is the angle the user clicked on the button that triggers rotation
the _rotateObj is a sprite that is drawn when they click that I make visible to show the actual rotation when I'm debugging
the _snapLock is the degrees the knob shold rotate to (10, 15, 30, etc)

I have a movieclip called view_mc and a button btn_rotate.
I want when the user click and drag btn_rotate button, he can rotate the view_mc movieclip clockwise and anti-clockwise.
I have written a code, but it only rotates the movieclip in clockwise direction:
ActionScript Code:
stage.addEventListener(MouseEvent.MOUSE_DOWN, on_stage_down);
stage.addEventListener(MouseEvent.MOUSE_UP, on_stage_up);
function on_stage_down(e:MouseEvent):void
[Code]....
so i have a movieclip with this script on it (this makes my movieclip rotates)
ActionScript Code:
onClipEvent(enterFrame){
angle = (Math.atan2(_root._ymouse-_y,_root._xmouse-_x)*180/Math.PI);
[Code]....
Now, i have (let's say) 30 frames inside this movieclip, and i wan't it to change is current frame depending on the angle of the mouse (example, if i point my mouse to the right, the mc goes to frame 30, if i point my mouse a little up, the mc goes to to frame 27, if i point my mouse all to the left the mc goes to frame 15... etc...)
Basically the movieclip should change it's frame depending on the mouse angle,
By the way, i don't really wan't the moviecliip to rotate (like it's doing now) i want it to change it's frame only...)
I have rotated an image around 0,0 using the code below. I need the new coordinates of the corners of the rotated image.
bitmap.rotation=_angle;
UPDATE: if i rotate an image 10 deg then that moves an image 10 deg clockwise from 0,0
the bottom left corner was 0,20 and so i need to change the point (0,20) 10 deg clockwise using trig?
I'm attaching the file so that you guys can see that? pretty basic. My main problem is to find out how can the mouse check the mouse position on stage and make the coverflow animate and the movieclip change angle depending on the side, I have to animate only 5 itens, here?s the AS:

Code:
knob_mc.addEventListener(MouseEvent.MOUSE_DOWN,turn);
stage.addEventListener(MouseEvent.MOUSE_UP,endTurn );
function turn(e:Event):void[code].....
This is the code I'm using to move a knob the challenge is when i click on the knob it turns 90 either left or right depending where i click, I'd like it to stay still until I turn the knob, and second how do I get the angle in whole numbers??
I want to be able to take a general sine wave y=Math.sin(x) and rotate it around some other angle, so instead of going strictly left-to-right, I'd like to go from, say, the top left corner toward the "center," or from the bottom right to the center, or any other arbitrary angle. Like this: I want to be able to use that wave as a "path" for enemies in a game, but I cannot seem to wrap my head around it. I've tried matrix transformations, but I was missing something there, too, because the origin was wrong.
View 1 RepliesFlash Tranformation Matrix via JsFL. I have to write a JsFL script that creates a text on my Flash scene, and rotate it with a random angle. Imagine I want to create and rotate a "Hello World!" at 45 degrees, my code looks like that:
rotateAngle = 45;
//creates my new text at x:0, y:0 coordinates
fl.getDocumentDOM().addNewText({left:0, top:0, right:10, bottom:10});
fl.getDocumentDOM().setTextString('Hello World!');
var mat = fl.getDocumentDOM().selection[0].matrix;
[Code] .....
The problem is : the rotation applied to my text is 58.3 instead of 45. I have to admit that I'm kind of noob with matrix... so I used the "matrix transformation for rotation" here : [URL].
I have a circle movieclip that needs to rotate to certain destinations depending on buttons pressed in the navigation. Everything works fine, except when you go from green to cyan and vice versa, it does a full 360 rotation instead of just moving to the destination.

i am following a tutorial from a book, Learning Actionscript 3.0, A Beginners Guide, where it discusses how to move an object in an agle. I have managed to get the app working fine, but i'm tryin to test it out in different angles but everytime i change it seems to go into the same angle.[code]Can somebody tell me why for everytime i changed the value of the degrees, it does not updat the movement of the ball please

Is there a way to set up an unseen variable in flash sort of like keeping score?The best way I can describe it is from the BASIC language I used to use back in the day, where on a click you can make x=x+1, or x=x-3, or whatever depending on the button you click on.And then it would display the score (i.e. whatever is the current value of x) in the corner? give me a link or the actual code you would assign to a single button that will add or subtract to a displayed score in the corner.

I have a project where I want to display a certain movieClip based upon what variable was set earlier. I have 5 different MovieClips that need to display depending on variables.
I have the variable set and working, but how can I script this to make it that if a certain variable say Var1 is set, then it chooses to display Var1_mc?
Can I just have it load the correct one, or do I just have it change the alpha setting of the correct one?
I have set the variable in my page using <param name="flashvars" value="menustate=<?php $pagename; ?>"> which works perfectly fine when I use a dynamic textbox in flash with the var name menustate.
But I need to send a MC to frame 2 if 'menustate = 2'. Anyhow, I just want to know how to control a MC with an external var. I can't use loadVars () because this var is coming from any page, not just one.
i'm trying to work out how to get a movieclip (of an arrow) to rotate then move in the direction it is pointing, controlled using the keyboard. Below is the code i have written so far, I can't get it to move in the correct direction. I also can't get it to keep moving after only one key press.

I have some texboxes which I need to stay a fixed distance away from another object at an angle.so I need to say textbox_mc position is 10 pixels away from my_Object at an angle of 35 degrees.The angle is changing and the object is moving, I think I can handle that if I know how to position by angle and distance.
View 7 RepliesI found a basic example of how to create something that'll shoot an object and create an arc based on an angle. I added a power Bar to it, but I noticed something bad about it.
The way it works the higher the speed is the further it goes and the faster it moves across the screen. This doesn't give me enough control. Because essentially I want fast moving projectiles but I want to also be able to shoot both near and far.
With this current system that's an impossibility.. Can anyone shed some light on how I can do this better? Here's the current way it's being done (important parts):
Code:
bullet = new Bullet;
this.stage.addChild(bullet);
bullet.speed = 1 + powerBar.scaleX * 20;
