Flash :: Formula To Determine Designation Point Given A Variable?
Aug 4, 2011
i have a game inwhich a bait is thrown determined by a variable of a power meter, when the meter is full it returns a variable of 1 when half 0.5 and when low near 0, how can i use this to determine how far my "bait will be thrown" onto the screen? i have tried how ever the X value would not be consistent with my fishing rod placement, and when the point is decided i will have to move my bait to that point and stop.

How to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)
[Code]....
But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension

First note: mathematically, I'm not that skilled at all. I played a game on iPhone a while back where you press a point, and an arrow fires from your castle which will always intersect the point you pressed. I wanted to make a similar game, thinking it would be an easy quick make; then I ran into the realization that the mathematics for this is actually beyond my skill level.
I'm assuming they're using a parabola formula or something which would determine the velocity and angle needed when the arrow is launched for the arrow to always intersect the clicked point. I only vaguely remember how parabolas work from school and have no chance of working out any formulas.

I can't pinpoint or make up a set of calculus to determine the right formula which describes a curve that goes through 3 specific points...I'll try to say it with a more hand-on approach. I have a spaceship which can move vertically,located to the left.The enemies, obviously, arrive from the right. Now, when i click anywhere on the scene,I want a missile/plasma orb/projectile to be shot from the spaceship, but doing more than going in a straight line: imagine 3 points, one at the spaceship, one in front (therefore to the right) of the spaceship (5/10 units in front) and the third at the click location. How do I determine the formula of the curve that goes along these three points?

How do you determine the "rotation point" (axis?) of an object?
A sprite/movieclip that has been loaded using a Loader has its rotation point set to the upper-left corner. What I want to know if how I manually (using ActionScript) set it to the center.

I have a list of fonts obtained via Font.enumerateFonts() and I want to display them all as 12 pixels tall. The problem is that I cannot simply set the point size because this can vary in actual pixel size for each font. So basically I want to determine what the correct point size is for a font in order to make it exactly 12 pixels tall. Because I'm doing this with a potentially large list I'm looking for an efficient method to do this.

I have a flash piece with all of the text loaded dynamically through xml.I also have several versions of the same xml translated into different languages (Russian, Japanese ect). Using this loading method, or others if one is better than the next, how do I set a variable to load in the specific xml for the specific site.Other words: Five different site versions, five different xml, using only the one flash file, as opposed to a different flash piece for every different xml... The Flash piece is unchanging except for the xml that is fed in.
Code:
import flash.net.URLLoader;
import flash.net.URLRequest;
var xmlLoader:URLLoader = new URLLoader();
var xmlData:XML = new XML();

I am trying to code a loan calculator into Flash, however AS3 doesn't like my formula and won't calculate it, can someone help? Here is what I have:
loan=15000
apr=13
term=48
var loan_amount = (apr + (apr / (Math.pow(trm, (1 + apr)) -1 ))) * loan;
When I print out the loan_amount I get a 0.If I do: var loan_amount = (Math.pow(trm, (1 + apr)) -1); it will give me the result 1.0331079714165e55
As soon as I add the next part of the equation (apr / (Math.pow(trm, (1 + apr)) -1 )); it will give me the actual apr value as the result instead of the apr divided by the 1.0331079714165e55.Likewise, if I try to add a fixed value instead of the apr variable, it will return that fixed value instead of doing the math.

I'm trying to just make an image center horozontally in the page when I addChild it. I figure the formula I need is the width of the of the image deducted from the width of the page divided by two... but I don't know how to make that into a formula, as in I don't know how to represent the size of the newly added child in the formula. Code is below.

I'm having a real problem trying to work this out...
A: I start with a movieclip on stage. it's 100x100.
B: I set xscale and yscale to 150.
C: I use "attachMovie" to add a little man into the square.The problem is, the man has an xscale of 100, but he is also scaled with the movieclip square container. So he appears too big.
D: What i would like to know, is what formula you would use to reduce his scale so he is the correct height, if the container movieclip had an xscale of 100?

I've been trying to look this up but not had any luck so far. I'm trying to make a simple pseudo-3D app, but I'm stuck on how to pull off the movement. If I have an object with x,y,z coordinates, and its movement speed, pitch, and yaw, what formula would I use for movement? So for example, if the object is at 0,0,0, moves 6 units per frame, and has pitch 30 degrees and yaw 15 degrees, what will be its coordinates next frame?

I have a little math problem with a game I'm making, and I can't for the life of me figure out the formula needed to accomplish something..Say, there's a sniping game, and a BIG image that must scroll from left to right according to the mouse movement.
Something like this:[URL]... In that example, the scene is 550 pixels wide, and the image is 1100, exactly two times the scene, so the formula is kinda easy..
[Code]...
the center of the image would be at x 1500, way over to the right of the scene, outside it, but it would fit inside the screen, like this (the blue square represents the real size of the scene):[URL]..Then when the mouse is at the far right side, that is 550 x, the image center should be at -950 x, like this:[URL]...

I've been searching for the formula used intrinsically in Flash but I couldn't find anything. Does anybody know how the result colors are obtained when the 'layer' blend mode is chosen for the upper object? I thinks it's done separately in each channel using the transparency values.There might be some bitwise operations going on there but I'm not sure.

i'm trying to dynamically layout a calendar using actionscript and i'm no good at determining algorithms to quickly and efficiently lay things out.what i want to do is set it up per the image attached:
* where there are 7 columns and a varying number of rows.
* the top row has the 2 arrows and the month and year display.
* the second row has all the day headings, i.e. S, M, T, W, R, F, S
* and the rest of the rows will have the dates.
how do i come up with a nice clean formula to calculate the positions so all these elements align?

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.

Currently, we have an activity in class wherein we're supposed to resize a Movieclip to a specified size restricted to any value between 50 and 250% that will be entered in an input text field. If the value entered goes beyond 250 or below 50%, it's also supposed to show a warning that the entered value isn't valid. Also, when a value is entered in the textfield, supposedly, it can be entered either by using the ENTER key or by clicking the resize button.
I've already managed to resize the movie clip according to the amount specified but I think there's something wrong with the "If" condition in my resizeShape function, because it still accepts values above 250 and below 50%. Also, I don't know how to make it so that both pressing the ENTER key and clicking the resize button enters the value without repeating the whole resizeShape function.Here's what I've done so far:
ActionScript Code:
var input_txt:TextField=new TextField();
var warningBig:TextField=new TextField();
var warningSmall:TextField=new TextField();[code]...........

I have an app that was actually written for me. It's a multiple choice quiz basically where a question comes up and there are 4 answers. HOWEVER the answer always seems to be 80% on the same answer ie: BUTTON ONE out of the four. BILLIANT random function I don't think.Would this be a better answer formula to use?
function randomBetween(a:Number, b:Number):Number { return (a + Math.floor(Math.random()*(b-a+1)));}
