ActionScript 3.0 :: Calculate Or Determine The Mouse Speed On The Stage?

Dec 5, 2009

How 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 :: Shoot An Object And Create An Arc Based On An Angle

Sep 21, 2009

I 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;

ActionScript 2.0 :: Object Follow Mouse At Constant Speed?

Sep 13, 2009

I am using Flash 8 and AS2. I have been looking and looking, but I cannot find how to have an object follow the mouse at a Constant speed. The code I keep on finding is something like this:
Code:
onClipEvent (load) {
_x = 0;
_y = 0;
speed = 5;
} onClipEvent (enterFrame) {
endX = _root._xmouse;
endY = _root._ymouse;
_x += (endX-_x)/speed;
_y += (endY-_y)/speed;
}
The "/speed" part makes the object move slower the closer it gets.

ActionScript 2.0 :: Any Way To Calculate Target Speed Value?

Jan 25, 2007

I 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 Based Upon An Mc Touching An Mc?

Dec 20, 2011

I have a running total. When an mc hits the table or hand it'll adjust the total. The problem is I only want the total to reflect when an object is resting on the hand mc. If i remove something from it, remove its value from the total. Now to be smart I have it add when an mc hits the hand, and remove a value if an mc hits the table. The problem, if I never touch the hand and keep dropping the mcs on the table, i get a negative value. Is there a way to calculate a total only when a mc rests on the hand mc

ActionScript 2.0 :: Calculate The Direction And Speed A Circle Has After Colliding With A Static (non-moving) Circle?

Mar 8, 2005

I'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?

ActionScript 2.0 :: Follow Mouse Only At Certain Angle?

I can't work out how to do this, but this is what I have so far..

onClipEvent (enterFrame) {
radians = Math.atan2(_root._ymouse-this._y, _root._xmouse-this._x);
degrees = (radians/Math.PI)*180;
_rotation = degrees;
}

How would I make it so that it can only point between 0 and 90 degrees?

ActionScript 2.0 :: Movieclip Frame Depending On Mouse Angle?

Sep 21, 2010

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...)

ActionScript 3.0 :: Calculating Mouse's Angle To The Center Of A Circle

I have a circle with 8 dots around the edge of it. Based on the center of the circle and the mouse's location, I want the dot that the mouse is closest to, to get bigger. I've got this so far ActionScript Code: angle = Math.atan2(rt.mouseY - y, rt.mouseX - x); But I'm getting some weird quadrant values returned that are between -3 and 3. Is there a way to know which degree out of a 360 circle my mouse is at in regards to the center of the circle?

ActionScript 3.0 :: Flash Change Preloader Animation Based On Internet Speed?

Aug 1, 2010

I have 4 animations and based on the speed of the internet i want it to change between each depending on the speed.

e.g...

0 - 10kb/ps - 1st MC
11 - 30kb/ps - 2nd MC
31 - 50kb/ps - 3rd MC
50+ - 4th MC

My idea is to have like a glass of water... and for the 1st MC the water filling it up is only a drip... and then 2nd MC is a slow stream of water etc etc and then final MC is water gushing in filling the cup up faster until it's full...

I think this might be a bit hard for me... as i can't even make a preloader... everytime i try the SWF file just stays blank until it's fully loaded... haha... but i'll read tutorials and stuff... i'm rather basic with Flash and just learn what i need to learn as i get to it... I also need the transition between each change (say from 1-10kbps - 51+) to be smooth rather than just having it going from a drip to gushing water... but i think i'll just have to make animations for each and then IF statements to deal with that issue..
