ActionScript 3.0 :: Rotation Speed On Mouse Position?
Sep 30, 2009I have a circle wheel i want to rotate and the speed should be based on the mouse position. I also need to have easing in and out.
When the user hovers over the bottom of the circle it will begin to rotate one way and then th top of the circle would make it rotate the other way. The further to the top or bottom they are the quick it spins. It ideally needs to ease in and out when it starts and stops when the user moves the mouse away.
The circle will be the complete movie so 50% top and bottom each for each direction.
ActionScript 2.0 :: Increasing Enemy Speed /cannot Seem To Change Speed
Mar 23, 2010I have a movie clip on my scene which has a speed applied to it making it move across the screen. This is duplicated when it reaches the other end of the screen.On my scene I have some action script which is acting as a timer. After a set time I want it to increase the speed of the movie clips, making the game become "harder". I seem to be able to manipulate the alpha of my movie clips but can't seem to trigger the speed increase.If i use a setInterval it seems to trigger the speed increase but it does it each time the movie clip is duplicated (so the delay resets, it does not change once and apply throughout)However, where I am changing the alpha I cannot seem to change the speed.

Sep 16, 2011For some reason the "scaled.width" - the movieclip that have scaled already - after scaling it even more with TweenLite.to function by factor .3 aren't equal with the predicted result => scaled.width * .3. Orginal width is something I don't know but scaled width is something like 420. Now multiplying it by factor .3 the result should be something like 140, now when I put TweenLite.to function to scale my scaled movieclip by factor .3 the width in the end is something like 267.And frankly speakin I really can't imagine where the result came from.
Some back ground:I import three images dynamically. Each of them to their own MovieClip containers. I don't know the dimensions of images so I need to scale them proportionally to their dimensions to fit to the desired size.That was intuitively easy. I managed also to align them horizontally in the center of the screen after the first scaling by the knowledge that their registration point can be found from the top left corner. I also managed to align each of them on vertically in the middle of the 1/3 part of the empty stage with desired marginals: in the top there are 20 pixels space, between the images there are 20 pixels space and in the bottom there are 20 pixels space.
Now the problems comes when I need to tween them to their final positions. Each of them to the top of the stage and each of them in 1/3 part of the empty space horizontally scaled at the same time smaller with factor .3.Intuitively when I think the x position can be found by same way than the way I found y positions (related to the space left after the middle image is positioned). So in theory I thought the x position for the image that comes in the center should be as much as finalX = stage.stageWidth / 2 - current.width * .3 / 2(the center point of the stage minus the half of the width of the image after the scale)but when I give finalX for the tweenLite as a x position and .3 as a scaling factor the result is something different.

View 3 RepliesActionScript 2.0 :: Any Way To Calculate Target Speed Value?
Jan 25, 2007I have some code that works out a target speed based on how far right of the screen ur mouse is as follows:
Code:
if(this._xmouse > value1 && this._xmouse < value2){
//set targetSpeed depending on how much greater than value1 it is
targetSpeed = this._xmouse-value1;
}
Is there an elegant mathematical way to calculate the targetSpeed value so that - it increases as xmouse gets greater, until xmouse is at the value that is the midpoint of value1 and value2, from when on, targetSpeed decreases as _xmouse gets closer to value2. So if value1 = 500, and value2 = 600, then as xmouse goes over 500, targetSpeed will increase 0, 1, 2, 3, 4 - up to 50. then as xmouse goes over 550 targetSpeed will decrease until xmouse is at 600, by then targetSpeed will be back to 0.
ActionScript 3.0 :: Calculate Or Determine The Mouse Speed On The Stage?
Dec 5, 2009How would you calculate or determine the mouse speed on the stage? What i am trying to do is this:
You have a custom cursor which shows a plus sign when you very suddenly and fast change the direction of the mouse to the right. When you do the same to the left, the cursor changes to the minus sign.
However, if you steadily move the mouse from left to right while the mouse cursor is showing the minus sign, the mouse cursor stays the same, only on very fast change of direction the cursor changes?
ActionScript 3.0 :: Calculate Width And Height After Object Rotation
Jul 31, 2009I am tweeing a bunch of rectangles randomly on stage.
Code:
TweenLite.to(thumbArr[i],1,{
x:Math.random () * (stage.stageWidth - thumbArr[i].width),
y:Math.random () * (stage.stageHeight - thumbArr[i].height),
rotation: Math.random () * (60) - 30});
the problem is that after I added random rotation (between -30 and 30 degrees), the corners of my rectangles are still sticking out of the stage at the end of the tween.
If I trace objects width and height after the rotation I get the new values but this still doesnt help me because I am tweening to that rotation.
Code:
mc.rotation = 20;
trace(mc.width);
trace(mc.height);

ActionScript 3.0 :: Set Random Movement / Rotation And Speed With Array
May 10, 2008I have a rock movieclip that is in an array and a timed function that places an instance of the rock on the stage every 5 seconds. So every 5 seconds a rock is placed onto the stage. What I want is when a rock is placed onto the stage it rotates either clockwise or anticlockwise. So every 5 seconds a rock appears and it will rotate either clockwise or anitclockwise. I also want the rocks to rotate at a random speed. So every time a rock appears its rotation speed will be different. I also need the rocks to move in a random direction. So every time a rock appears it will travel in a different direction to the previous rock.

ok!?
now i put the space_mc on the stage and scale it to 20% the stage (document properties) are w800xh600
Now i want that the USER clicks on vlak1,2_mc and the space_mc scales to 100% But the clicked vlak(1,2)_mc must have the exact coordinates as in the space_mc?
so if clicked on the vlak1_mc!
the space_mc zooms in to 100% and the _x,_y of the vlak1_mc are x100,y100 on the stage(800x600)?

ActionScript 2.0 :: Calculate The Direction And Speed A Circle Has After Colliding With A Static (non-moving) Circle?
Mar 8, 2005I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision
If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?

View 6 RepliesActionScript 3.0 :: Using A Carousel Script That Rotates Some Images, The Speed Of The Rotation Depends On Where The Mouse Is On The Screen?
Feb 5, 2010I'm using a carousel script that rotates some images, the speed of the rotation depends on where the mouse is on the screen. The project I put it into is 962 pixels wide, the carousel itself is about 400 pixels wide, I want it positioned on the right half of the project, so I put the code in a blank movie clip and positioned it on the right.
It works fine, but the problem is the rotation gets crazy fast as the mouse moves to the left side of the stage, because there's so much more space on the left then there is on the right. I only want for it to stop gaining speed when the mouse leaves the carousel area.
Code:
//We use 70x70 sized images (change this if different for your images)
const IMAGE_WIDTH:uint = 70;
const IMAGE_HEIGHT:uint = 70;

Mar 18, 2006I am currently making a game, similar to StreetFighter,where enemies will come on from the side and you fight them. Now i have the character movement and attacks fully scripted, and have made an enemy, and i make it move towards the character using:
onClipEvent(load){
movethy = 7;
scale = _xscale;[code].....
Now this works quite well and the enemy stops when it hits the character, but the problem is, it wont complete a full attack, instead it plays a few frames of the attack MC. Now i have every attack in a different MC (Frames 2-5) inside the Enemy MC. How can i make the enemy pause when it reaches the character, then choose an attack to use? From there i'll be on my way and can script the hittest and so forth.

ActionScript 2.0 :: MC Movement - Rotation And Position
Apr 24, 2005I'm having a problem with a little movement script I wrote for a MC I have. I believe it either has to do with variable scoping, or with a coordinate system problem. (If I change the xPos and yPos in the onClipEvent (load) to 0,0...then the MC starts in the middle of the field (MC) I'm trying to move it inside of.) Basically...the ActionScript you see below is a part of the "Player" MC...who is supposed to move around a "field" MC I have.
I was assuming setting xPos and yPos to 0 would have the Player MC starting at the very top left of the entire screen...which instead it starts in the middle of the "field" MC.) Also - When I press the different arrow keys...the Player MC jumps around to different locations...but once at the new location the movement (in a single direction) works okay.
