I have Layer A with the skill button and Layer B with the plyer sprite, what I need is that, when I touch the skill button and the plyer will use the skill.
How can I let the Layer B know that when I touch the button?
Is there anyone can show me with simple demo?
I think the best way is use a Singleton structure. In example, do a DataModule, create getters and setters, and call them using the static pointer to write or read data.

I am new to Lua scripting, and game development. So please I am just a noob in Lua.
I have searched the net for solutions to my problems, without any luck.
I use Photoshop, Corona, Dusk, json and Tiled on windows7.
I am creating a "board" like game, i.e. Setlers. I am using a world map, as the background. The background image of the game area is a world map (world.png file). I have no problem here.
I would like to create transparrent clickable objects matching the countrys borders on my gamemap with all parameters and values (I have added in Tiled) stored in the object. So When the player clicks on the country the transparrent object (on top of the map) is the one clicked and an eventlistener acts on the click.
In Tiled I can create all the objects I need, naming them + assigning parameters and other values.
If I add object.alpha value in Tiled, the alpha value is passed on to corona and working there.
How can I read these data from the json/tmx file in Corona and adding them to a lua table?
The way I am thinking to use the Tiled map and its objects, is to create one polyline trace of each country’s border (creating one object per country). Then place each “country traced object” on top of the world.png map, also naming the object with the countrys name like “object.name = TileBritannia” and also the other properties for use in game.
My problem is getting the objects info, like object.name, and an eventlistener reacting to a click on the object.
Is a polyline the right way to create a clickable area on a map, when I use a png file as a background image?
What is the best way to create a country border objects, in one layer or with all countries as individual object layers in Tiled.
Can I create one layer with sub objects and still access them in my code?
How do I get the object name and other properties, set in Tiled.
When I try to use the (local britannia = tiledMap:load("britannia.json")) the "load" is not working, getting a nil value.
I am looking for a code that will extract/get/read the object.name i.e. “objBritannia” or "TileBritannia". from the json/tmx file.
When I try to read the different parameters from the json file, I don't get the result I expect. I get the result = function: 046A73B0, was hoping for an object name of some sort.
Please provide links to or code example.
I have edited the question.
Thanks
For questions 1 and 2: I have not used Tiled, but based on Corona Tiled, you have the right strategy in mind. That page makes me think that you can just use tap event listener to detect tap. If you are having issues with the example on that web page, please update your question to be more specific. If tap event handling doesn't work (maybe you're talking about a different Tiled lib), look a Polygon fill and Point in Polygon detection, because that's basically what you need to do. Try some stuff from there. If it still doesn't work for you, then update your question with specifics otherwise it will be likely get closed (it is a little too broad as it is).
For #3, Lua is a dynamic language that supports adding properties to objects in one line. So upon the example on the Corona Tiled page, all you would have to do is
tiledMap = require("tiled")
local britannia = tiledMap:load("britannia.json")
britannia.name = "Britannnia"
local Zulu = tiledMap:load("zulu.json")
zulu.name = "zulu"
Naturally you will probably have a whole bunch so you will create a function that you call for each tile. It's not clear what map.layer["objBritannia "].nameIs("TileBritannia") is supposed to do so I can't comment.
Say I have this specific button class in Flash called cont_button and it's supposed to be used to break out of a loop, but I want to use the class more than once. Is there a way to give every instance of this class some kind of parameter so that it knows which frame it nees to go to?
Example:
I have an instance of cont_button on frame 200 and there's a loop between 200 and 210. This cont_button executes a gotoAndPlay(211). But later on I have another instance of the button on frame 315 and a loop between 315 and 325. Is there a way to make it so each instance knows which frame it specifically needs to go to via the use of a variable? Or am I going to have to make an actionscript file for each individual one?
Pretty new to ActionScript so I appreciate the help and if there are good coding references to AS3 you guys recommend, I'll gladly look those over.
Sure, this is possible. One way you can do this is make the frame numbers class variables and when the button is clicked, they reference whatever value is stored in them, rather then hardcoded numbers. To get a better idea, can you post the relevant parts of your button class?
As you say, you need to pass a parameter to each instance of the button. There are lots of different ways you could do this, but I'd be tempted to just do it via the instance names.
You could name each button loopBreakTo211, loopBreakTo326 and so on, then in your button's class have:
var breakFrame:Number = Number(name.replace("loopBreakTo", ""));
(parent as MovieClip).gotoAndPlay(breakFrame);
Admittedly that's not a very robust way of doing it (for example, it will break if a button is named incorrectly and breakFrame ends up as NaN, so you might want to add a check for that), but it keeps the parameter together with the instance instead of in the timeline somewhere.
How would someone go about coding a 'window'? I'm starting to make a GUI, and I want to learn how to code one. One that can be skinnable, and one that actually loops and creates itself at runtime. I understand that this might be a bit vague, so I'll add details.
One that actually 'creates' itself. Most GUI tutorials I've looked on depends on an 'image' that just gets added on the screen. I want to be able to use skins in my windows. One where my 'skin' is just a collection of 'borders'. Then when I insert window.create(50,50) where 50,50 is my height, width, It would just create that window, following the skin.
I understand that it probably follows just like when a language draws a rectangle, it just follows a different set of rules (maybe?). However, for all my Google-fu skills I cannot find a tutorial that teaches me this.
Please Help. I didn't include the language I used as you can see, because I believe I just need to know how to create one. Anyway though, I am using Actionscript 3. A tutorial would be just fine, or even A SINGLE CLASS THAT HAS THIS FUNCTIONALITY, I'll just study the code. Or if you know one, maybe a whole book about GUI and programming it :D
Pure As3.0 GUI coding is quite troublesome. I try to Googling, but not come out well. anyway for my case, i generate using a SWC, and Class Mapping and Customizing. but i'm not sure best way. in other way i use a bit101 library. this is gives me want Window, Charts, Componets easily of high abstraction. see the below image.
It can be pretty hard and complicated to do, or very easy, it just depends on how flexible your solution should be. You need firstly to design a structure of your program and approach to the problem.
I like to go from the image of how it should look like from API point of view. I think I would create a GUI element like this:
var wholeGui:MyGUI = new MyGUI();
var window:IGuiElement = new GuiWindow(dataObject, skinObject);
wholeGui.addElement(window);
So what would you need?
1) Object that would manage all GUI elements. Why? Simply because your GUI elements shouldn't be destroyed by themselves if user will click "X" on your little window. The wholeGui object would manage them and listen for any events including those that would destroy them. You may consider creating custom events for interaction between the wholeGui object and your window object if this interaction is going to be complicated.
2) Interface for your GUI objects. Some problem here is that AS3 actually doesn't have interface for Sprite, and you would like to interact with it like with extended Sprite. The workaround here is to have in this interface a declaration like this:
function asSprite():Sprite;
And your implementation in GuiWindow would look like this:
public function asSprite():Sprite {
return this;
}
And your GuiWindow class should extend Sprite of course. Then you would have access to it's Sprite properties and methods by writing for example: window.asSprite.startDrag();
This interface should give you abilities that you need to operate on your GUI element.
3) Class for your GUI element, in this example GuiWindow.
4) Class for your data that would be injected into your element. If you would load data dynamically, and from some location, you would need to deal with the situation when no data can be provided - but that logic would be inside your window.
5) Class for your skin - so you would be able to dynamically create a skin object and use it to create your window in a way you want.
That's just few thoughts to consider.
PS. It may be good idea to fill GuiWindow object with data AFTER creating it, and not in constructor, as you would be able to visualize loading process then.
hi i am developing a game using libgdx. I want to make the texture object available to entire application. I have a requirement like, initialize the texture in one application listener and i want to use it in another application listener. Can anyone help me on this.
There are two ways I think you can do this. First, you could read the data into a static variable. For an example of this, take a look at the Art class in metagun demo: Art.java. The second way, which I have not tried yet, is to use the new AssetManager class. There is example use in the AssetManager test. These should help you access your textures more easily.
You don't need to have 2 or more Application listeners. Actually that only makes things harder.
Use Screens instead (extending Game in your core class instead of directly implementing ApplicationListener).
Either way, you should be able to just send the textures as arguments. For example I have a class Assets that contains all the textures and I sent it to each screen. You can make them static as Doran suggested too.
When creating some extended MovieClip to the stage using AS on Actions of some frame, on which layer this MovieClip is created? On layer where Actions were? If I wanna move it down, for example, can I simply move the Actions layer? And by the way, one more question, what if I would not create Actions layer and write all the code on some used one? :SS
whenever you add objects through ActionScript it will not consider your layers it will add on the top of the display list. and for traversing into movieclips u can use MoveiClip(root) or MovieClip(parent). check out addChildAt() and addChild() methods of ActionScript for more info.
Hope u mean nested MovieClips
