Hey everyone so I am having some trouble trying to get this to work correctly. I have a MC Object called character and another called "points". I have a container object called planetContainer I add the character to the planetContainer the character is rotating around the planets that are also added to the container. The main issue I am having is when the points power up is activated I want the points to move off the other planets and to the charactercenter position. It was working perfect but had to update some code and remove the Points out of the planetContainer and attach them to the planets instead. I know I might have to use localToGlobal but not too sure.
Here is how I setup the character:
private function newCounterClockWise():void
{
planetContainer.addChild(character);
character.rotation = (Math.atan2(character.y - planetHit.y, character.x - planetHit.x) * 180 / Math.PI);
}
How the points are added to the Planets:
private function addPoints():void
{
points = new mcPoints();
var planetPosition:Point = planetContainer.parent.localToGlobal(new Point(0, 0));
points.x = planetPosition.x;
points.y = planetPosition.y;
outerPlanets.addChild(points);
aPointsArray.push(points);
}
Now this is the main function that handles the points to move to the character but it is not working correctly. The points move but they move off the screen or cause the game to kinda tweak out and do different things. Also the "magnetHandler(); is in my EnterFRame Event:
private function magnetHandler():void
{
for (var i:int = 0; i < aPointsArray.length; i++)
{
var currentPoints:mcPoints = aPointsArray[i];
var characterPosition:Point = planetContainer.parent.globalToLocal(new Point(character.x, character.y));
if (currentPoints.hitTestObject(playScreen.mcPointsHit))
{
trace("POINTS MID STAGE");
currentPoints.x -= (currentPoints.x - characterPosition.x);
currentPoints.y -= (currentPoints.y - characterPosition.y);
//currentPoints.x = character.x;
//currentPoints.y = character.y;
//TweenMax.to(currentPoints, 0.5, {x:characterGlobalPosition.x, y:characterGlobalPosition.y , ease:Power1.easeInOut } );
}
}
}
Can anyone see what I am doing wrong?
It's a hard to understand your question fully (or to understand why you're putting things that relate to each other in separate containers), but likely this line is where it's falling down:
var characterPosition:Point = planetContainer.parent.globalToLocal(new Point(character.x, character.y));
What you want to do, is get the characters x/y coordinates in the currentPoints parent space. To do that, you would do something like this:
//first, find the global position of character:
var globalCharacterPoint:Point = character.localToGlobal(new Point());
//then, convert that to the currentPoints parent local space:
var localCharacterPoint:Point = currentPoints.parent.globalToLocal(globalCharacterPoint);
Also, in this code of yours:
points = new mcPoints();
var planetPosition:Point = planetContainer.parent.localToGlobal(new Point(0, 0));
points.x = planetPosition.x;
points.y = planetPosition.y;
You are getting the global space of the planetContainer's parent, which is probably NOT what you want. You likely want:
planetContainer.localToGlobal(new Point()); //this gives you the global location of the planet container's top left corner
And, since you're adding the points object to outerPlanets, you probably want to convert to its local space (unless it's positioned at 0,0 globally - then it doesn't especially matter).
var outerPoint:Point = outerPlanets.globalToLocal(planetPosition);
points.x = outerPoint.x;
points.y = outerPoint.y;
Needless to say, for games it's best to have everything in the global coordinate space unless it's truly encapsulated assets (like smoke on a rocket etc.)
I am having this problem in developing this snakes and ladders game and i am very much hoping that you guys can help me out. i already created the board and the avatar. only thing is i cant make the avatar move up the ladder, and move down with the snake. can somebody help me? i am very much desperate right now, and every help is appreciated, thank you guys!
EDIT:
here's the code that i have written so far here are some of the codes I have written so far..

i dont know where to put the if statement of executing the motion tween attached to the chip(avatar)
Well here are my initial thoughts. I would create an animation with your character who you want to move up and down. To make it simple, make an animation for climbing, then one for falling. It's really easy to do, just use the tween option on the timeline after inserting your keyframes.
Looks like you've created your animations. Now, whether or not he slides up or falls down depends on where your snakes and ladders are. Only you know that, so at those particular spots on your board (for example, x = 200 and y = 200) we want the if statement to occur. But we only want it to occur after your avatar is done moving. Probably create a new function and add the following to the mover function
var checkX:Number = chip.x;
var checkY:Number = chip.y
checkLandingSpace(checkX,checkY);
Now let's make a function checkLandingSpace which will check if we are on a shoot or ladder
function checkLandingSpace(checkX:Number,checkY:Number):void
{
if (checkX = (your point) || (another point) //first check all x points...continue like this for all points where a ladder is...the || means or
{
if (checkY = (your points....etc)
{
mc_avatarLadder.play(); //choose your instance name to be mc_avatar, then play the tween
}
}
}
Or check this post for equating one variable to any element in an array If [Get Variable] is equal to [Array]
Now write the that for your ladder. Then do the exact same thing with all of your shoots points. Except, make a new animation with instance name mc_avatarShoot then just say mc_avatarShoot.play();
After that, make sure on the last frame for both instances, you just put in gotoAndStop(1); just to make sure it's ready next time you go to play the animation.
Of course, adjust your timer appropriately. This should pretty much do it, there might be a couple things to adjust for your own game, but follow this and understand it and you'll get it.
First of all sorry for some english mistakes. Portuguese is my first language(I am from Brazil)
Im trying to make a space game from scratch in AS3 and the way to move the ship is like in the game Air Traffic Chief.
I succeed at some point. But when the ship is very fast it start to shake and its not very smooth and clean as I want.
Here is what i have done: http://megaswf.com/s/2437744
As the code is very big so I pasted in pastebin: pastebin.com/1YVZ23WX
I also wrote some english documentation.
This is my first game and my first post here. I really hope you guys can help me.
Thanks in advance.
Edit:
As the code is very big i will try to clarify here.
When the user MouseDown and MouseMove the ship every coordinate is passed to an array.
When the user MouseUP this array is passed to a function that fix the array.
For example: If the distance between two coordinates is greater than 5px, the function creates a coordinate in the middle of the two coordinates.
if I take this function off the problem seen to be solved. But if the user move the mouse very slow it still happens. It also creates a problem that i was trying to solve with that function. as the distance of the two coordinates are very big when the ship arrive in one coordinate most of the line path disappear.
I uploaded a version without the function that fixes the array. http://megaswf.com/s/2437775
I think there is 2 ways for solving this problem
1- Try to fix the noise in the array of coordinates 2- Take off the function that create an coordinate between two points and try to fix the problem of the line path disappear.
Here is the 2 important functions:
this function moves the ship
private function mover():void
{
if (caminhoCoords[0]!=null) // caminhoCoords is the array that contain the path
{
var angulo:Number = Math.atan2(this.y - caminhoCoords[0][1], this.x - caminhoCoords[0][0]);
this.rotation = angulo / (Math.PI / 180);
this.x = this.x - velocidade * (Math.cos(angulo));
this.y = this.y - velocidade * (Math.sin(angulo));
var testex:Number = Math.abs(this.x - caminhoCoords[0][0]); //test to see the distance between the ship and the position in the array
var testey:Number = Math.abs(this.y - caminhoCoords[0][1]);
if (testey<=velocidade+2 && testex<=velocidade+2) // if is velocidade+2 close then go to the next coordnate
{
caminhoCoords.shift();
}
}
}
This function draw the line:
private function desenhaCaminho():void //draw the black Path
{
if(caminhoCoords.length>=1)
{
caminho.graphics.clear();
caminho.graphics.lineStyle(1, 0x000000, 1,true);
caminho.graphics.moveTo(caminhoCoords[0][0],caminhoCoords[0][1]);
for (var i:int = 1; i < caminhoCoords.length; i++)
{
caminho.graphics.lineTo(caminhoCoords[i][0], caminhoCoords[i][1]);
}
}else
{
caminho.graphics.clear();
}
}
Every time the ship arrive in one coordinate is take that coordinate off the array and redraw the array.
Is there a better way of doing that?
I believe if you set your registration point of the plane to the centre and use .snapto(path), it will improve the action.
Judging from just the look of the stuttering, I would guess you need to smooth out the "line" a fair bit. It's probably picking up a lot of noise in the line, which is then translated into the rotation of the plane. Either smooth out the rotation/position of the plane, or the line itself.
I have loaded some images through XML and attached into dynamically created MovieClips named mc0,mc1,mc2...etc.
_loader.removeEventListener(ProgressEvent.PROGRESS, onLoadingAction);
count++;
var img:Bitmap = Bitmap(e.target.content);
img.cacheAsBitmap = true;
img.smoothing = true;
img.alpha = 0;
TweenLite.to(MovieClip(my_mc.getChildByName("mc"+count)).addChild(img),1, {alpha:1,ease:Quint.easeIn});
and within ENTER_FRAME handler
for (i=0; i < mc.numChildren; i++)
{
my_mc.getChildAt(i).x -= Math.round((mouseX-stage.stageWidth/2)*.006);
}
Everthing works fine. But it is shaking so that it was not looking good.
How do I achieve smooth movement?
One solution I've used is to round the (x,y) position to the closest integer. No matter that you've added smoothing to your bitmap and cached it, rounding could make it feel less choppy and way smoother.
Another thing you need to be careful is the dimensions of the images. Images that have an odd dimension won't be smoothed the same way as images with even dimensions. Check how to workaround this in my blog post Flash Smoothing Issue.
Since Flash has a variable frame rate (in the sense that it will drop frames), one shouldn't depend on the entering of a frame as a unit of action. Rather, it would be wiser to calculate the elapsed time explicitly.
For instance, in the enter frame handler:
var currentTime:Number = (new Date()).time;
for (i=0; i < mc.numChildren; i++)
{
my_mc.getChildAt(i).x -= speed * (currentTime - lastTime); // speed is in px/ms
}
lastTime = currentTime;
where you have the variable lastTime declared somewhere in a persistent scope:
var lastTime:Number = (new Date()).time;
I don't know if this addresses what you are calling "shaking", but it's at least something to consider.
