If you didn't do this, the game loop would lock up the interface, not allowing the user to close the program while playing the game.

You need to run your game in another thread to allow the GUI to stay functional. The main method simply creates a new thread from which the GUI-building and general game function operates. All this does so far is create a full-screen frame with no content. We will start by building the primary class, which I called TopClass, and we will build just the skeleton as you see below. Now we will start programming! *and there was much rejoicing* (sorry for the cheesy Monty Python humor) This can all be seen in the demo video I provided in the previous step. In the center of the screen will be a button to click when you're ready to play, and every time a round begins, you will fade to and from a black screen. The background would be the same as the game's background (moving pipes from right to left). For example, in this game, I envisioned the game to begin on a splash screen.

In the concept building phase, you should also get an idea of the GUI layout and general gameplay characteristics of the game you will write. This ensures the transparency of everything besides your graphic. One important factor to remember in designing your graphics, should you choose to do so, is to use only interlaced png images and remove the background from your images. I used Photoshop Elements to design the images. This is only necessary based on the code I provide however you may change the folder name to something of your preference. You should place the images in a folder called 'resources' which you will place under the bin folder in your program's files.

zip I include below this step to ensure you have exactly what is needed. I wouldn't grab the step's images above for your program. All three images are found above and they should be named as follows: I rotated the pipe 180 degrees and used two separate images for the top and bottom pipes. I designed a static blue bird and a pipe for the obstacle. You will inevitably think of added functionality while programming, so have the vast majority of the concept finalized beforehand.īecause my game idea was remaking the popular Flappy Bird, this stage was limited to designing the graphics to be used in the program. Take time to put together a '95% model,' which has everything you think your game will need on the conceptual level. Your code will be written and rewritten wasting a significant amount of time. Here you make sketches and draft ideas on your game's functionality. This is always the first stage of building any game.
