I want to retrieve the correct calculation of the following:
Code:
answer = 1 - -0.05;
I want to do 1 Minus -0.05 (negative 0.05), the correct answer should be 0.95 Obviously with the syntax I am using is not working...
@ 1) I have a big problem with Math.random logic in the animation on the top of this website ( danceacademy.cz ). If you leave it for lets say 3 minutes it'll start breaking (see for yourself please).
@ 2) Also animation shows mostly the Yemi guy which is undesirable behavior . That's because he is on the end of the code ( else { // In case the random number is 1 myMainMovieClip = new yemimain(); )

I want to get a value between 1 and 50 placing a value of 100 which will be the variable computerTotal:
Code:
computerPlay = Math.ceil(Math.random()*computerTotal);
Here of course it will display a number between 1 and 100 (computerTotal = 100)
What i want is to have a random number between 1 and the half of computerTotal
How could this be accomplished?
i just want to learn the correct process of random math. in AS3.creating a star field. that loops no extra's just continues to loop.the ones i found where used by wasd, or arrow keys, dont want none of that.
View 14 RepliesHere is the problem:
var p:int = 0;
var n:Number = 0;
n = 32.999999999999999;
p = Math.floor(n);
trace(p); // returns 33
n = 32.11111111111111;
p = Math.floor(n);
trace(p); // returns 32
I would expect both of these to return 32. I have searched, and it seems this is an unreported bug in AS3. Or ... am I doing something wrong?
Wat is the diffrence between these two?

View 2 RepliesI'm trying to get the depths of all the blocks to be at the correct levels at the correct times so that the 3d effect is maintained. I've tried many things, but have had little success. All the instances of the blocks are stored in an array, but since it's adding them in accordance with when they're added to the stage, it doesn't help me locate them to swap depths. Is there a way to arrange them by location on the board?
View 4 RepliesSo here is a piece of code that I have seen used a lot but don't really quite understand:
myVar = Math.min(Math.max(myVar, this.min), this.max);
or some variation thereof. I understand that the function first finds the maximum value of two values then turns around and uses that to find the minimum between two values.why this is done? And how do you know when to use it?

View 3 RepliesSo i think i have fully coded my calculator but it still doesn't seem to be performing the calculations correctly. I can't see where i am going wrong. If i perform a calculation let's say 6*2 it outputs NaN then i straight away + by let's say 5 it outputs NaN again. And it doesn't make the operators display only once, so if i click on '+' twice it will display twice in the display when it is meant to only display once and in one of my functions i cleared the display field so that it would replace the number's when the next operation is performed but it doesn't seem to be doing that. I have been going over the code several times but i can't seem to identify where the problem is coming from.

I have not added the full code as it is too long, i have just added the parts which relate to each other. I am just doing everything entirely through actionscript, nothing is on stage apart from the display and answer text fields.

I know that the eq for finding the distance between two points in 3D space is:
d = ((x1-x2)^2 +(y1-y2)^2+(z1-z2)^2)^(1/2)
the problem is I dont know x2 (the x value of MC2 (the one set at z = 50)).

Would like to understand the basic process behind an ecard before I attempt to construct one!Obviously there could be the following elements:Initial web page containing a Swf (choose swf) offering a user a choise of ecards and a consisting of a series of text input fields to collect recipients and senders address and a message. With actionscript that calls a php file on the server.
Passing variables holding the card choise the card text the email from and to etc from swf to php file.The php script runs and creates a copy of a swf card, the one chosen by the user(swf1) It populates the swf copy with text from the variables set by the choose card swf.the php then sends an email to the recipient address with ? and this is where I am unclear?Does it send an attachment of the swf1 or how does it do it?
I'm making a game based on pong. At the start of a round, the ball will go in a random direction and when the ball hits a paddle the ball will move in a certain direction depending where it hit the paddle. The more centralized the hit is, the more straight the bounce is. Here's the tricky bit: the ball may hit either a vertical or horizontal paddle and I want the xspeed(horizontal movement) or yspeed(vertical movement) of the ball to increase/decrease in proportion to the opposite speed while keeping the same general speed of the ball(it can decrease and increase). Here's an example(you might want to get a pen/pencil and a piece of paper):
Let's say the ball is moving at 45 degrees(so it's going downward right) and hits a horizontal paddle smack dab in the middle, thus it goes at 270 degrees(straight up). So, at first the xspeed and yspeed are both the same, then the xspeed is zero and the yspeed is at the max(to the general speed).However, let's say that the ball hits the same paddle but at the edge(either edge will do the same) thus making the ball go at a near 360 degree angle, making the xspeed near max and yspeed almost zero. Like I said, I want the two speeds to increase/decrease in proportion to the general speed, this is so that xspeed or the yspeed don't exceed the general speed.
I need to do a simple calculation and have it update and display the result without me having to click a button.On the stage I have two text fields.The one on the left is a input text field with the instance name of "input" (without the quotes)To the right is the other text field. It is a dynamic field with the instance name of "output" (again, without the quotes)When typing into the input field I want it to multiple the value by 10 and display the result in the output field.If I then change the input value it needs to automatically update the output field.

And its not just straight geom because we dont know the ACTUAL x value of the second MC. It thinks its at x:500 but when you look it will look farther to the right than 500

How can we split this kind of calculations
I have XML data that looks like this: 197,168,198,168,204,168,206,168,207,169,208,etc This stuff is XY coordinate pairs, X1, Y1, X2, Y2, X3, Y3, etc. and are used by a drawing function to trace out a particular freeform shape. This array of data is usually 200-400 items long.Here is the AS code that is handling the reading of the XML and the drawing of the shape. This all works wonderfully:
[code]...
I am looking at the array and grabbing some points out, namely the first and last XY pairs, which I need for something else. That's the origXexp, origYexp stuff.The real problem is that I need to run a mathematical calculation on the data in this array. While this is a little hard to explain, I need to create a variable, let's call it expert_area, and then sequentially rip through that long string of numbers and do the following math (I'll use the simple X1 Y1 example): expert_area=0 expert_area = expert_area+((X1*Y2 - X2*Y1)/2)
where we move through the long string a pair at a time. So the first calculation would be (X1*Y2 - X2*Y1), the next would be (X2*Y3 - X3*Y2), (X3*Y4 - X4*Y3), etc. I've tried building loops to get the length of the expertArray[i] and then using that as the basis to proceed through the data. But everything I try either produces no results, or gets Flash stuck in an infinite loop. I'm unsure of where to put this, and how to construct it.

Why does the - sign and + sign appear before the = instead of after?Is this a logic operator(-= or +?Why doesn't putting the - sign or + sign after the = work?
I´d like to know how would I make a formula for the calculation of speed.It´s not as simple as distance divided by time.I want something different.I have an helicopter.This helicopter is landed.He will take off with a small speed, but increasing speed.What I want is.This helicopter movement. In other words, increasing vertical speed, in a given time, say, 2.4 seconds, in a give distance, say, 100 pixels.After that he keeps vertical speed constantly. So I think the helicopter will start with its vertical speed slow, increasing, then, decreasing untill it reachs its constant vertical speed.
