Whenever actionScript compiler can't find the specified property, it flags it with compiler error 1120.
currentMin and onTimerComplete are the name of your offending property.

Anyone know if this is a Dart bug or is it my misunderstanding of how Dart coding works?
I am learning Dart to investigate feasibility of eventually using Flutter; however, while exploring the language, I found a weird behavior (maybe a bug). I tried repro'ing it by writing a similar pattern of code, but have yet to figure out what causes it. In the attached code, I wrote a quicksort class. In that class, it counts the number of times the "sort" method is recursed and saves the count in a class member called "recurseCount".
From the main() class, if I use the QuickSort class directly, I have no issue getting back the recurseCount member; however, if I call it from a different class (called "Tester"), I do not get the correct value for "recurseCount". Why would calling a class from a separate class cause members to not provide the correct values?

Currently I'm working on a project recreating a mario level, my issue is that when I do not hard code the bottomLimit (the floor, currently set to 400) Mario will eventually just fall through.
Another thing I can't quite figure out is how I can move my invisible block that creates the floor boundary to accomodate the flooring. The level chosen is the Fortress level of Super Mario Brothers 3, if that helps picture what I'm trying to do with it.
There are a couple .as files to my code, I will put my troublesome file in along with my collision code.

I think what you want to do is to set the bottomlimit, but not hardcode the number 400, correct?
I would do change your createFloor method:
private function createFloor(xPos:Number, yPos:Number):void
{
var floor:Floor = new Floor();
addChild(floor);
floor.x = xPos;
floor.y = yPos;
floor.height = 16;
_floor.push(floor);
floor.visible = false;
// set bottom limit here
bottomLimit = yPos;
}
... then you wouldnt need to set it to 400.
However, another option is to change your if statement:
if(_mario.y >= Floor(_floor[0]).y)
{
_mario.y = Floor(_floor[0]).y;
vy = 0;
onGround = true;
}
else
{
onGround = false;
}
... and then you can get rid of the bottomLimit variable completely
(assuming I understood your code, and that the floor tiles are always going to be at the bottomLimit)
Making a touch based platform game based in actionscript 3 using Gary Rosenzweig's game as a basis, all was going well until today, I've been trying to swap out floor objects etc without changing much of the actionscript at all and I have the following error.
ArgumentError: Error #2109: Frame label jump not found in scene jump.
at flash.display::MovieClip/gotoAndStop()

at PlatformGame/gameLoop()[C:\Users\Michael\Desktop\platformGame\PlatformGame.as:303]
This also seems to cause problems with collision detection.
The code is as follows. (not i have not changed the scene or label names from the originals but it still shows the error).

The error is with the following line and is occurring because the referenced MovieClip does not have a frame labelled "jump":
char.mc.gotoAndStop(char.animstate);
My guess is that you made a change to the MovieClip which contains your character and, in doing so, removed the label which the code above references.
I have the following setup loaded:
import com.greensock.*;
import com.greensock.easing.*;
import com.greensock.plugins.*;
TweenPlugin.activate([FramePlugin]);
OverwriteManager.init(OverwriteManager.AUTO);
and am using the following code to tween an mc to frame 20.
TweenLite.to(circle, 1, {frame:20, ease:Elastic.easeOut});
Problem is nothing happens, circle is a variable containing my mc and traces fine.
Output of
trace(circle); = _level0.circle
Can anyone see why this isn't working? The MC contains a shapetween.
Edit:
Ok so I have tested it in a new fla with the same MC and it isn't the MC that is the problem it has to do with some other part of my code preventing it.
Here is my entire code... can anyone see anything that would stop the tween to frame working? If I remove for (MovieClip in txts) {
txts[MovieClip]._alpha = 0;
} and put the tween above it it works, but as soon as it is inside a rollover again it doesn't.

Heh Solved, for some reason it doesn't like for (MovieClip in Array){} anywhere in your code, so if I substitute that for for (a in Array){} it seems to work. Odd.
I am using the following code to tween an movieclip once _global.choiceMade equals 1...
onClipEvent (load) {
import mx.transitions.Tween;
import mx.transitions.easing.*;
}
onClipEvent (enterFrame) {
if (_global.choiceMade == 1) {
var myTweenX:Tween = new Tween(this, "_x", mx.transitions.easing.Back.easeOut, this._x, -349, 0.5, True);
}
}
This is contained within each frame of the main timeline. The first time it runs fine but on the next frame it runs incredibly slow (takes about 12 seconds not 0.5 and is very choppy), if I then return to the first frame and run it again now this time it is extremely slow.
I can't work out why its doing this my CPU stays around 6-15% while its running so it can't be too demanding.
Updated to show rest of my code:
On main timeline have a frame each containing a movieclip. On the timeline of each of these movieclips contains:
//tint an object with a color just like Effect panel
//r, g, b between 0 and 255; amount between 0 and 100
Color.prototype.setTint = function(r, g, b, amount) {
var percent = 100-amount;
var trans = new Object();
trans.ra = trans.ga=trans.ba=percent;
var ratio = amount/100;
trans.rb = r*ratio;
trans.gb = g*ratio;
trans.bb = b*ratio;
this.setTransform(trans);
};//Robert Penner June 2001 - http://www.robertpenner.com
MovieClip.prototype.scaleXY = function(to){
this.onEnterFrame = function(){
this._alpha = to-(to-this._alpha)/1.2;
if(this._alpha > to-1 && this._alpha < to+1){
this._alpha = to;
delete this.onEnterFrame
}
}
}
scoreUpdated = 0;
Answer = 1;
_global.choiceMade = 0;
Buttons = new Array(this.buttonHolder.True, this.buttonHolder.False);

In this movieclip there are two movieclip buttons (True and False) containing this code:
onClipEvent (enterFrame) {
this.onRollOver = function() {
this.gotoAndStop("over");

};

this.gotoAndStop("down");
whichChoice = this;
_global.choiceMade = 1;
counter = 0;
};
if (_global.choiceMade == 1) {
this.enabled = false;
this._parent.scoreNow = _global.score;
this._parent.scoreOutOf = (this._parent._parent._currentframe)- 1 + ( _global.choiceMade);
if (thisValue == this._parent._parent.Answer && whichChoice == this) {
myColor = new Color(this);
myColor.setTint(0,204,0,13);
this._parent._parent.Answers[0]._alpha = 100;
this._parent._parent.Answers[0].scaleXY(100);
this.tick.swapDepths(1000);
if (counter == 0) {
_global.score++;
counter++;
}
}
else if (thisValue == this._parent._parent.Answer) {
myColor = new Color(this);
myColor.setTint(0,204,0,13);
this.tick.swapDepths(1000);
}
else if (whichChoice == this) {
this._parent._parent.Answers[1]._alpha = 100;
this._parent._parent.Answers[1].scaleXY(100);
myColor = new Color(this);
myColor.setTint(255,0,0,13);
this.cross.swapDepths(1000);
}
else {
myColor = new Color(this);
myColor.setTint(255,0,0,13);
myColor.setTint(255,0,0,13);
this.cross.swapDepths(1000);
}
}
}
The script at the top is on a movieclip these buttons are contained in called buttonHolder which does what it says, and tweens the buttons across the screen to reveal a next button once an answer is chosen.
From what I can see, as long as you have choiceMade == 1 you create a new effect! which is not ok. because in 1 sec at 15 fps you will have 15 tweens running :(
try yo set choiceMade = 0 or somehting else than 1
onClipEvent (enterFrame)
{
if (_global.choiceMade == 1)
{
_global.choiceMade = -1;
var myTweenX:Tween = new Tween(this, "_x", mx.transitions.easing.Back.easeOut, this._x, -349, 0.5, True);
}
}
Without seeing the rest of your code it's hard to see exactly what's going on. But it looks like you never change choiceMade and it continuously recreates the tween.
onClipEvent (enterFrame) {
if (_global.choiceMade == 1) {
var myTweenX:Tween = new Tween(this, "_x", mx.transitions.easing.Back.easeOut, this._x, -349, 0.5, True);
_global.choiceMade = 0;
}
}
