I'm trying to implement a game mechanics of "Hooking" objects... Here's picture of what i'm talking about:
But I have a problem with the chain/string of the hook.
I've tried create it step by step when the hook is on the fly, using timer and enterFrame events, but they both generate huge gaps between chain segments.
I've tried creating big image of whole chain and changing width dynamicly, but it only stretches and looking funny :D
Maybe anyone faced the same problem?
I would suggest you to try following.
Create whole chain
place it inside container (display.newContainer)
change width of container.
Container automatically generates masks so instead of stretching you will have just part of your chain hidden under mask.
here is link to container docs http://docs.coronalabs.com/daily/guide/graphics/container.html
This is not a complete answer - I have given you a bit of a broad answer to a broad question but I hope it can help you in creating what you need.
I created a very similar mechanic recently -
I used enterFrame to call a function, lets call it BuildHook, this would check the position of the hook and the position of the starting point and then calculate how many pieces of images would be needed to fill out the space. The graphic I had as my "hook" was partially larger then the chain pieces allowing for it to overlap and only put a new image once enough space between the last piece and hook was created.
This ment that it was the hook moving forward and backwards and then having a static "chain" between it and the starting point. Either consuming "links" as would move backwards ontop of them or created "links" as it moved away from them.
Keep in mind this is pseudo code but should give you an idea how to make it.
local arrayOfPieces = {}
local function BuildHook()
-- Bunch of variables you need to get
startX,startY,
hookX,hookY,
lastPieceX,lastPieceY,
singlePieceWidth
-- The hook pseudo code
if(hookX - lastPieceX >= singlePieceWidth) then
local newPiece = display.newImage('singlePiece.png');
newPiece.x = lastPieceX + singlePieceWidth/2
newPiece.y = lastPieceY
table.insert(arrayOfPieces,newPiece)
end
if(hookX < lastPieceX) then
lastPieceArrayPos = table.getn(arrayOfPieces)
table.remove(arrayOfPieces,lastPieceArrayPos)
lastPiece = arrayOfPieces[lastPieceArrayPos - 1]
end
end

I am using rdesktop with seamlessrdp. This way I can open Windows apps on my Linux machines. Also I added devilspie2 to the mix so I could control the window decorations. devilspie2 uses lua as its config management. I made everything work. The only issue left is to move the opening (dialog) windows a couple of pixels because the VNC windows will appear as if they had decorations (but without them). I got the code working by hard coding the amount of pixels needed to move. The issue is we have more than one distros here and they have different pixel sizes for their window decorations.
What I want is to GET the decoration size in pixels instead of hard coding them so it will work perfectly for all my distros.
Here is the piece of code that does it atm:
if get_window_class()=="SeamlessRDP" then
undecorate_window();
--x-1 and y-28 works for one distro but for the other I need to use x-6 and y-27
if get_window_type()=="WINDOW_TYPE_DIALOG" then
x, y = xy();
xy(x-1, y-28);
end
end
As you can see from the script. It would be much better if I could somehow call the size of the window decorations and then use them rather than hard coded pixels.
EDIT (ANSWER):
Even though I found the answer before the following post, I wanted to accept it anyways because it did show the right path to follow. I am only further commenting here to show the full answer:
--get x and y's for decorated and non-decorated windows
x1, y1, width1, height1 = get_window_geometry();
x2, y2, width2, height2 = get_window_client_geometry();
--calculate pixels to slide window
xpixel = x2-x1;
ypixel = y2-y1;
--check if class is seamlessrdp
if get_window_class()=="SeamlessRDP" then
undecorate_window();
--if window is a dialog then move it
if get_window_type()=="WINDOW_TYPE_DIALOG" then
xy(x1-xpixel, y1-ypixel);
end
end
devilspie2 provides only two ways to get the window size, get_window_geometry and get_window_client_geometry.
Whereby the last one excludes the window borders. If this does not work for you, you can create a file with a table for all values to make them easily editable. You could also use the window class names as table keys if possible to make the use easier.
I'm using Paintcode V3 and last Xcode for my project.
In Paintcode I draw a red path, kind of "clock hand" with a radius variable to be able to rotate it.
In my Xcode project, this custom UIView is added to a main view.
When the red path is rotating, I need to know when it intersects with another element of the view.
I tried:
if self.redPathView.frame.intersects(self.anotherView.frame) {
//do something...
}
but it can't work because redPathView is the entire Paintcode canvas (the square frame) and not only the red path.
I'm searching a way to access to the red path of my view.
Interesting problem.
I don't think there is a way to do exactly what you are looking for...
Like you mentioned, when we use PaintCode, our custom drawings become an entire UIView.
We can't access its specific elements (like your redPathView).
(I'm favoriting this question in case anyone knows if we actually can. I may be wrong.)
Anyway, there is a workaround. You could use PaintCode itself to tell you when "collisions" happen. Of course, then you would need to draw everything there... And implement some sort of internal control that would make sense to you.
For example, in the picture below I created this "clock hand", with functions to detect when the red thing touches other UI elements (key point there is the touchedElementID expression -- observe how it updates itself with the "ID" of the rectangles):
There are some issues you may find with this approach, for example the need to know the exact position of other elements on the screen and possibly complex ternary constructions like:
(rotationSanitized <= -352 || rotationSanitized >= -8) ?
1 :
(rotationSanitized <= -82 && rotationSanitized >= -98) ?
2 :
(rotationSanitized <= -172 && rotationSanitized >= -188) ?
3 :
(rotationSanitized <= -262 && rotationSanitized >= -278) ?
4 : 0
Also, how to "export" and consume this information along with the StyleKit in Xcode?
The trick I did was to add an empty (no Fill, no Stroke) UI element in PaintCode and associate the touchedElementID expression result to the alpha value of the element.
This way I could access the expression in my custom view, for example via StyleKit.touchedElementID. But that introduces a new problem since now I have to change the generated StyleKit every time it is exported (two lines of code, but still). That is kind of a fragile solution.
However, if you are ok with that, then it's just a matter of consuming this new information...
For that I created a protocol, so my ViewController can act as the delegate of my custom view, and perform whatever it needs to do when the most internal UI elements in PaintCode are "touched".
Here is the final result:
Finally, check this project in GitHub with all the code and samples.
I have a symbol of a person standing, he have child movieClips like hands, legs, head, body....so then if i press a button or click in the stage how do i need to change the animation instantly?
I suppose:
1) create a new movieClip that has all the same parts but animated as walking(for example) and then make something like:
if(keypressed)
{
person.replaceSymbol(myNewAnimatedSymbol); //method that not exist
}
2) for example if my standing animation longs from 1 to 30, i can make another animation in the same line let's say from 31 to 60 where he is running and then write:
if(keypressed)
{
person.legs.gotoAndPlay(31); //in the 60 frame he go back to 31 by using gotoAndPlay(31)
person.hands.gotoAndPlay(31);
person.body.gotoAndPlay(31); //and so on...
}
Can you give me an advice of which of methods I need to use? or if you have a better idea how to make it...
Hm-m-m. I'd say your second approach is easier to both draw and control, especially if it'll eventually come to reskinning your MC, say your person will get dressed in a cloak that's attached to the body and arms, your "new animated symbol" will likely require a change to accommodate that clothing, while in case of one symbol you can assign its parts another look, like say person.hands.cover=clothing.handpart; person.legs.cover=clothing.legpart etc, and then the animation will contain references to cover being changed, so that correct parts of clothing will appear around all the moving parts.
In fact, you might not need separating your person into different body, hands, legs etc MCs, but instead make it so that your person's legs are a container that can hold either a bare body part (naked leg drawing) or a dressed body part (a boot, pants, etc), and animate the main part by making these containers move according to how a person should walk, stand, run, attack etc etc., so that you will have a single point to dress the entire set of your person's animations.
It depends for example my character has around 100 animations. Putting them in a single timeline and telling them to go from this label to that label (or frame) is a huge mess to manage.
So I have 100 library items with export symbols. I keep on switching between them. This makes it easy to manage.
So, I think the question is how many animations do you have? Can you manage them in a single timelines? If you can , I'd say go with labels or frame jumps.
Both of your methods are correct and your second method would be faster because you're not adding or removing anything from the display list.
I am a beginner at ActionScript3, and for my learning purpose, I am trying to build a match3 kind of game. I am making is a clone of bejeweled kind of game. but instead of swapping, I have to delete those elements and shift the upper elements down and add new elements above those shifted elements.
I am able to delete matched elements and after matching I'm removing those elements but I am stuck with the shifting code. I am not able to shift those elements down.
I believe that you should take a look at Richard Lord's Tetris source code as your game may be somehow similar in mechanics to Tetris. Tetris shifts down rows when you get lucky.
Richard Lord is one of the Flash Gurus and his way of doing things may seem pretty advanced for a starter like you. Take a look over the source code and see if it fits you. What I can tell is that this is the proper way to make a game but maybe it's not the best point to start for a novice like you that is in urgent need.

I would approach it like this in 2 parts.
Loop through your array of board positions starting from the bottom row and check for an empty unoccupied slot, if you find one do another loop through the row above till you find a piece on the same column. If you find a piece on the row above apply a tween to move it down to the empty slot and continue your loop.
Once you have looped through all rows, and animated all the tweens you need to loop through again to find all the gaps that need gems dropped into them. Create new elements at those positions and then move them up by (element height * row), apply another tween to animate them back to their starting position.
Is there any possible way to create a slider that will create a range similar to what is done with one handle using min/max, only instead of min/max, starting the range from say 50 (on a scale from 1-100)? I realize this will most likely require modification of the slider or creating a plugin, just wondering if anyone has done this already or knows how to go about it.
I.e. something like this: http://jqueryui.com/demos/slider/rangemin.html
Only, instead of the range going from the min, going off of where the handle is, and allowing the user to slide either left or right of that fixed starting point to create the range. Any help is appreciated, and I'd be glad to clarify what I need if that doesn't make sense! :)
I'm not sure I understand the question. You want something (what?) to be based on the initial position of the slider "thumb"???
