I'm trying to get the log on my program to update with every button press *see picture below, however it will only display the data on the first time it has been pressed. I'm not sure if that's because it's in a for loop.
Initialise button
stop();
import flash.events.MouseEvent;
var MAX_ORGANISMS: int = 12;
var MAX_GENES: int = 2;
var genotype: Array = new Array();
var MAX_PARENTS: int = 2; // number of parents organisms to select
var MAX_CHILDREN: int = 2; // number offspring per selected parent
var generation: int = 0; // to count the generation being shown
var list_selected: Array = new Array(); // list of selected org.
var number_selected: int;
var geno_text: String = "";
function random_genotype_initialisation(): void {
generation = 0;
number_selected = 0;
var org: int;
for (org = 0; org < MAX_ORGANISMS; org++) {
list_selected[org] = 0;
var genotype_1organism: Array = new Array();
genotype_1organism[0] = randomRangeInteger(1, 4);
// gene1 = head colour (4 types)
genotype_1organism[1] = randomRangeInteger(46, 49);
// gene2 = head width (44 - 48)
genotype_1organism[2] = randomRangeInteger(50, 55);
// gene3 = head legnth
genotype_1organism[3] = randomRangeInteger(1, 4);
// gene4 = eye type (4 types)
genotype_1organism[4] = randomRangeInteger(30, 35);
// gene5 = eye width (30 - 35)
genotype_1organism[5] = randomRangeInteger(1, 4);
// gene6 = nose type (4 types)
genotype_1organism[6] = randomRangeInteger(10, 18);
// gene7 = nose height (10 - 18)
genotype[org] = genotype_1organism.slice();
}
}
function randomRangeInteger(min: int, max: int): int {
var randomNum: int = Math.floor(Math.random() * (max - min + 1)) + min;
return randomNum;
}
function show_phenotype(): void {
var org: int;
var org_property: String;
for (org = 0; org < MAX_ORGANISMS; org++) {
org_property = "o" + org + "_head";
this[org_property].gotoAndStop(genotype[org][0]);
this[org_property].width = genotype[org][1];
this[org_property].height = genotype[org][2];
org_property = "o" + org + "_eyes";
this[org_property].gotoAndStop(genotype[org][3]);
this[org_property].width = genotype[org][4];
org_property = "o" + org + "_nose";
this[org_property].gotoAndStop(genotype[org][5]);
this[org_property].height = genotype[org][6];
geno_text += "Geno" + org + " has initialised." + "This Geno has a " + genotype[org][1] + " by " + genotype[org][2] + " face" + "\n" ;
geno_log.text = geno_text;
}
}
function initialise(event: MouseEvent) {
random_genotype_initialisation();
show_phenotype();
}
initialise_btn.addEventListener(MouseEvent.MOUSE_UP, initialise);
The program has some faces, which change features randomly, each time the user presses the initialise button. Which by my knowledge shows that the button handler works, and the program is performing correctly, however, the text does not follow suit and only changes once.

I'm trying to get to convert the decimals to a fraction so for example, I had written something such as var _pow:int = Math.pow(base,i) and if i turned out to be a negative number it would give out a decimal (example: 3 ^ -2) and I'm currently stuck trying to find a way to turn _pow into a franction (so _pow out of a 100) so I tried to do var _pow:int = Math.pow(base,i) * 100 which should stop it from being a decimal but it's not showing in the dynamic text, and this only happens if i is negative
package{
import flash.display.*;
import flash.events.MouseEvent;
public class name_ extends MovieClip{
public function _name_(){
btn.addEventListener(MouseEvent.CLICK, input)
base.restrict = "0-9\\.\\-";
pow.restrict = "0-9\\.\\-";
answer.multiline = true;
}
private function input(event:MouseEvent):void{
var pow = pow.text;
var base = base.text;
var answerText:String = "";
if(pow > 0){
for(var i = 1; i <= pow; i++){
_pow = Math.pow(base,i);
answerText += ("\n" + base + " exposant(power) " + i + " = "+ _pow );
answer.text = answerText;
}
}else{
for(i = 1; i <= pow; i++){
var _pow:int = Math.pow(base,i) * 100
answerText += ("\n" + base + " exposant(power) " + i + " = "+ _pow );
answer.text = answerText; //Dynamic text
}
}
}
}
}
Have you tried using an "if" statement? Something like if(i <= 0){code}.
You can also try using the Math.floor(number to be rounded down); or Math.ceiling(number to be rounded up)
How to Save positions for 3 objects in Array to make random position between each other by AS3?
import flash.geom.Point;
var arry:Point = new Point();
arry[0] = arry[78,200];
arry[1] = arry[217,200];
arry[2] = arry[356,200];
//object called b1
b1.x = arry[0][0];
b1.y = arry[0][1];
//object called b2
b2.x = arry[1][0];
b2.y = arry[1][1];
//object called b3
b3.x = arry[2][0];
b3.y = arry[2][1];
//make objects swap positions between each other
var rand:Number = (Math.random()*arry.length);
//output to see random position [[78,200],[217,200],[356,200]]
trace(arry);
to get random with tween like this... https://www.youtube.com/watch?v=8m_m64plQ6E
At compile time you should get this Error I suppose : "ReferenceError: Error #1069"
Here is a way to store the positions (like in the link you provided from youtube) :
import flash.geom.Point;
var squareWidth:uint = 40;
var squareHeight:uint = 40;
var marginX:uint = 100;
var marginY:uint = 75;
var spacer:uint = 10;
var positions:Vector.<Point > = new Vector.<Point > (9);
function setPositions(v:Vector.<Point>):void {
var count:uint = 0;
var posx:uint;
var posy:uint;
for (var i = 0; i < 3; i ++)
{
for (var j = 0; j < 3; j ++)
{
posx = (j * squareWidth) + (spacer * j) + marginX;
posy = (i * squareHeight) + (spacer * i) + marginY;
v[count] = new Point(posx,posy);
count++;
}
}
}
setPositions(positions);
trace(positions);
// output :
// (x=100, y=75),(x=150, y=75),(x=200, y=75),(x=100, y=125),(x=150, y=125),(x=200, y=125),(x=100, y=175),(x=150, y=175),(x=200, y=175)
So here you have nine Points to place the clips like in the video.
You just have to add a function to swap the nine boxes stored in another Vector.
In your case.
For 3 positions do the following if I understand your question.
import flash.geom.Point;
var positions:Vector.<Point> = new Vector.<Point>(3);
var p1:Point = new Point(78,200);
var p2:Point = new Point(217,200);
var p3:Point = new Point(356,200);
positions[0] = p1;
positions[1] = p2;
positions[2] = p3;
trace(positions);
// output : (x=78, y=200),(x=217, y=200),(x=356, y=200)
So, you're still unclear!
Your issue is to find a random position?
This may help you if this is the problem you're facing :
import flash.geom.Point;
var positions:Vector.<Point > = new Vector.<Point > (3);
var numbers:Vector.<uint> = new Vector.<uint>();
var numbersAllowed:uint = 3;
var rndNmbrs:Vector.<uint> = new Vector.<uint>(3);;
var p1:Point = new Point(78,200);
var p2:Point = new Point(217,200);
var p3:Point = new Point(356,200);
positions[0] = p1;
positions[1] = p2;
positions[2] = p3;
trace(positions);
function populateRndNmbrs(n:uint):void {
for (var i:uint = 0; i < n; i++)
{
numbers[i] = i;
}
}
populateRndNmbrs(numbersAllowed);
function populateRandomNumbers(n:uint):void
{
var rnd:uint;
for (var i:uint = 0; i < n; i++)
{
rnd = numbers[Math.floor(Math.random() * numbers.length)];
for (var j:uint = 0; j < numbers.length; j++)
{
if (rnd == numbers[j])
{
numbers.splice(j,1);
}
}
rndNmbrs[i] = rnd;
}
}
populateRandomNumbers(numbersAllowed);
trace("rndNmbrs = " + rndNmbrs);
for (var i:uint = 0; i < numbersAllowed; i++)
{
trace("b"+ (i+1) + ".x = " + positions[rndNmbrs[i]].x);
trace("b"+ (i+1) + ".y = " + positions[rndNmbrs[i]].y);
// In place of trace, you should place the boxes at those random positions.;
}
//output:
//(x=78, y=200),(x=217, y=200),(x=356, y=200)
//rndNmbrs = 2,0,1
//b1.x = 356
//b1.y = 200
//b2.x = 78
//b2.y = 200
//b3.x = 217
//b3.y = 200
Is that what you want? Or do you want to know how to create a motion effect?
I'm not sure about what you really need...
This will help you to place all the boxes in a random position.
You may do this like here bellow, and add a function to check if the random positions are not the same.
With only 3 MovieClips, you will often have the same random positions as long they're stored in the "positions Vector"
var squares:Vector.<MovieClip> = new Vector.<MovieClip>(3);
function populateMCs(target:DisplayObjectContainer,n:uint):void{
for (var i:uint = 0; i < n; i++){
squares[i] = target["b"+(i+1)];
}
}
function swapMCs():void{
for (var i:uint=0; i<squares.length; i++){
squares[i].x = positions[rndNmbrs[i]].x;
squares[i].y = positions[rndNmbrs[i]].y;
}
}
populateMCs(this,numbersAllowed);
swapMCs();
I give you a last example to get a motion effect in AS3.
I'm not a translator AS2 -> AS3 and a video is not the best way to show your code :(
This will make your boxes move smoothly, but not the way you want.
Now, you have to learn AS3 and try to make the job by yourself.
Then, if you have another issue, just ask clearly what you want.
var friction:Number = 0.15;
setDestination(squares[0],squares[0].x,350,friction);
setDestination(squares[1],squares[1].x,350,friction);
setDestination(squares[2],squares[2].x,350,friction);
squares[0].addEventListener(Event.ENTER_FRAME,moveClip);
squares[1].addEventListener(Event.ENTER_FRAME,moveClip);
squares[2].addEventListener(Event.ENTER_FRAME,moveClip);
function setDestination(mc:MovieClip,x:uint,y:uint,friction:Number):void{
mc.destinx = x;
mc.destiny = y;
mc.f = friction;
}
function moveClip(e:Event):void{
var mc:MovieClip = e.target as MovieClip;
trace(mc.name)
mc.speedx = (mc.destinx - mc.x);
mc.speedy = (mc.destiny - mc.y);
mc.x += mc.speedx*mc.f;
mc.y += mc.speedy*mc.f;
if((Math.floor(mc.speedx)<1) && (Math.floor(mc.speedy)<1)){
mc.removeEventListener(Event.ENTER_FRAME,moveClip);
trace("STOP MOVE FOR " + mc.name);
}
}
I'm not entirely sure if this is possible at all, but I'm trying to take a string in Flash and check to see if it is the same as the name of an already existing variable. Here is a piece of my code:
var randomNumber:int;
var randomNumberS:String;
var Mem1:String;
var Mem2:String;
randomNumber = Math.floor(Math.random()*3);
randomnumberS = ("Mem" + String(randomNumber));
TGiven.text = [the randomnumberS string, except as either the variable name Mem1 or Mem2]
Is this a possible task, and if not, is there a better way to perform this task? It would be very useful as I plan on making many more variables that start with Mem with higher and higher numbers.
It would be optimal if the variables were a member of a class or Object, to which you could evaluate whether they exist using hasOwnProperty().
For example:
var obj:Object = {
Mem1: "value1",
Mem2: "value2"
};
You could test whether obj has a property by name:
obj.hasOwnProperty("Mem1");
Applying your example using random numbers:
for (var i = 0; i < 100; i++) {
var randomNumber:int = Math.floor(Math.random() * 3);
if (obj.hasOwnProperty("Mem" + randomNumber))
trace("Mem" + randomNumber + " exists.");
else
trace("Mem" + randomNumber + " does not exist.");
}
You can also use the in keyword, such as:
"Mem1" in obj;
Using the same example:
for (var i = 0; i < 100; i++) {
var randomNumber:int = Math.floor(Math.random() * 3);
if (("Mem" + randomNumber) in obj)
trace("Mem" + randomNumber + " exists.");
else
trace("Mem" + randomNumber + " does not exist.");
}
I want to make an flash application which picks and gives it one value between four variables randomly.
So I wrote this code:
import flash.events.Event;
var max:int = 100;
var red:int = 0;
var yellow:int = 0;
var orange:int = 0;
var blue:int = 0;
function updateChart():void
{
var total:int = red + yellow + orange + blue;
redbar.height = red / total * max;
yellowbar.height = yellow / total * max;
orangebar.height = orange / total * max;
bluebar.height = blue / total * max;
redres_txt.text = String(red);
yellowres_txt.text = String(yellow);
orangeres_txt.text = String(orange);
blueres_txt.text = String(blue);
total_txt.text = "Total: " + String(total);
}
Vote_Button.addEventListener(MouseEvent.CLICK, onRedClick);
function onRedClick(evt:MouseEvent):void
{
var randomSelector:Array = [red, yellow, orange, blue];
var random:* = randomSelector[Math.floor(randomSelector.length * Math.random())];
random++;
updateChart();
}
This is the whole code. The problem is; when i click the button, the numbers returns to zero and other clicks doesn't affect. The fla file is here if you want to look at it:
https://drive.google.com/file/d/0B2f6Y60ccirBamt1RThKV2VqSjg/edit?usp=sharing
Thanks.
Change your onRedClick handler like this:
function onRedClick(evt:MouseEvent):void
{
var randomSelector:Array = ["red", "yellow", "orange", "blue"];
var random:String = randomSelector[randomSelector.length * Math.random() | 0];
this[random]++;
updateChart();
}
I'm creating a flash game where objects are falling from the sky and the player needs to destroy them by clicking on them. But I have a problem, sometimes they spawning one on top of each other.
Here is an example what I mean:
Objects should be spawned near other, but not one on other.
Here is my constant vars:
public static const GRAVITY:Number = 3;
public static const HIT_TOLERANCE:Number = 50;
//Powerup
public static const APPLE_END_Y:Number = 640;
public static const APPLE_SPAWN_CHANCE:Number = 0.02; //per frame per second
public static const APPLE_START_Y:Number = 110;
public static const APPLE_SPAWN_START_X:Number = 50;
public static const APPLE_SPAWN_END_X:Number = 500;
//Scoring
public static const PLAYER_START_SCORE:Number = 0;
public static const SCORE_PER_APPLE:Number = 10;
Here is part of code where objects spawning:
private function update(evt:Event)
{
//Spawn new apples
if (Math.random() < randomChance)
{
//spawn x coordinates
var newPirmas = new Pirmas();
newPirmas.x = Math.random() * C.APPLE_SPAWN_END_X + C.APPLE_SPAWN_START_X;
var newAntras = new Antras();
newAntras.x = Math.random() * C.APPLE_SPAWN_END_X + C.APPLE_SPAWN_START_X;
var newTrecias = new Trecias();
newTrecias.x = Math.random() * C.APPLE_SPAWN_END_X + C.APPLE_SPAWN_START_X;
var newApple = new Apple();
newApple.x = Math.random() * C.APPLE_SPAWN_END_X + C.APPLE_SPAWN_START_X;
//spawn y coordinates
newPirmas.y = C.APPLE_START_Y;
newAntras.y = C.APPLE_START_Y;
newTrecias.y = C.APPLE_START_Y;
newApple.y = C.APPLE_START_Y;
newPirmas.addEventListener(MouseEvent.CLICK, onClick);
newAntras.addEventListener(MouseEvent.CLICK, onClick);
newTrecias.addEventListener(MouseEvent.CLICK, onClick);
newApple.addEventListener(MouseEvent.CLICK, onClick);
itemsToSpawn.push(newPirmas, newAntras, newTrecias, newApple);
}
}
As someone said: As for making sure they don't overlap, you can keep a history of their spawn points, and change how you get their random X value. Just iterate through the array of previous X values, and make sure the new one isn't within (oldX + (width/2)).
But I can't make It successfully, could you help me with keeping history of their spawn points? Thank you very much.
var t:Array = [];
t[0] = [APPLE_SPAWN_START_X, APPLE_SPAWN_END_X + APPLE_WIDTH/2];
t will keep the available intervals the you can generate new apple.
In the start time, there is no apple, and the t has only one interval, the starX of the interval is APPLE_SPAWN_START_X, the endX of the interval is APPLE_SPAWN_END_X + APP_WIDTH/2.
where you want to generate a new apple, you would find a availble interval in t, if we find the interval as mInterval(the interval could put in the apple, means endX - starX >= APPLE_WIDTH), then we could generate your new apple.
We just need to change the lines in you update function like
newPirmas.x = Math.random() * C.APPLE_SPAWN_END_X + C.APPLE_SPAWN_START_X;
Instead
newPirmas.x = mInterval[0] + Math.random()*APPLE_WIDTH;
When we set newPirmas.x, we have break the mInterval and generate two new interval,
the values are [mInterval[0],newPirmas.x] and []newPirmas.x + APPLE_WIDTH, mInterval[0]],
so we need to delete the mInterval in t and put the two new intervals into t.
