I am trying to develop a game like ninja jump in ios with cocos2d + box2d with endless scrolling ! (no need of parallax scrolling)
What is the best practice for endless scrolling
1 : moving the layer (Ie changing the layer position)
2 : moving the Camara
3 : using parallax scrolling with single layer (ie using only one parallax layer with same speed)
Or any other better approch
?
You can take a look to this tutorial: How to Make a Game Like Jetpack Joyride using LevelHelper and SpriteHelper.
It explains you how to make an endless scrolling game like (Jetpack Joyride) using Cocos2D and Box2D.
I think you should consider Parallax scrolling approach ..!
You can use parallax scrolling for the background layer and reset the game objects once they go out of the screen.

Unity 3d has two viewpoints, one is game and another isscene. when you move objects in scene you can see changes happened in game in the same time. while the reverse is true. But UE4 doesn't have this function. So I wonder if I can develop a plugin for UE4 to achieve that? does anyone have a clue?
enter image description here
Unreal 4: Go to Window -> Viewport 2. Drag the window somewhere and you will have 2 viewports:
Press play, only one viewport will display the "gameview" and the other remains as "sceneview" - Moving stuff in the 2nd Viewport will not update the game!
But I found this plugin:
https://github.com/jackknobel/GameViewportSync
You can see if that works for you or use it as a reference to get started developing your own plugin.

As an option for rendering UI over a game I am currently developing I was thinking about how viable QML (Qt5) would be. Given that you are limited to only drawing when Qt gives you the signal, how viable would writing a game such as; a first person shooter of the quality of say... ArmA 3 (graphically wise, not taking into account content creation or budget); be in Qt/QML on a desktop platform if you used QML for only a 2D interface over top of the game (think menus and HUDs)?
To be more specific, what sort of performance loss would you get by rendering a high-fidelity FPS game like this then rendering an interface over it using QML?

How can I make zoomable square table like in the picture below?
At first, there is no tile in squares.
but when zoom in, tiles are slowly appearing inside squares.
And another question, can I have paint bucket tool and use to fill my tile then store information into array?
In SFML this can be done using a so-called sf::View. This allows you to have a world defined and have different and changing views on it, like in your example.
There is a very good introduction to Views in SFML here.

I am interested in making a GUI-intensive strategy game with C++ and GTK+. What I would like to know is how feasible it would be to add 2D game graphics to a GTK program. Basically I would be wanting something like a game screen, with interactable 2D graphics, flanked by menus and the ability to navigate to other screens that would be GUI only.
Note that I have never used GTK before, nor have I before programed a GUI (nor graphics either).
It's certainly possible with GTK, but you have to ask yourself whether you're using the right tool for the job. Use Clutter, which is much more suited to animation and integrates with GTK; or perhaps better yet, use a game programming toolkit.
Here's an example of two non-intensive proof-of-concept games written with Clutter, with links to their source code.
It's possible. I did it with GTK and Vala some time ago. Here is a blog post I wrote about it. Basically it's very much like the games you make with Java and Swing. Just override the expose signal and create a timer for regular redraws. Here's an article on developing a 2D Snake game in PyGTK.
In pseudocode, all you do for the game infrastructure is:
start()
{
tick_timer( 1.0 / FPS );
load_all_sprites_etc();
}
tick()
{
update();
game_board.expose(); // game_board is a GTKWidget, preferably a DrawingArea
}
expose_event() // connected to game_board
{
drawing_code();
}
update()
{
game_physics();
game_logic();
}

as the title says, I want to add my main window a banner in the bottom of the window that shows text that runs from left to right, just like you can see in your TV when watching fox/CNN...
I'm using QT 4.5.2
Thanks a lot :)
You have many options. You could:
Create a custom widget and override QWidget::paintEvent()
Drawing your text to an image and then repainting that image as often as needed
Creating a QGraphicsScene and then moving an appropriate text item around.
QTimeline and/or QTimer will likely be useful in your implementation. The key idea is that you need to draw something at different positions at consistent intervals. If you redraw frequently enough, it will look like an animation.
