Become a videogame developer master with Gosu and Ruby.

This car has No Brakes! Help the car stop inside the goal - here's how: Drag and drop CONES in the car's path to slow it down. Drag and drop CONTROL ZONES in the car's path to make it turn. Can you beat all 4 levels?! TROUBLESHOOTING: On Windows a box pops up that says: 'Windows protected your PC. Wait a few minutes. Wake your Mac by interacting with its trackpad, mouse or keyboard. Remove any chained adapters. You can't force a Mac to play nicely with an incompatible external display by chaining multiple adapters together!

Bored of develop amazing websites? Want to try something totally different, but without leaving our beloved Ruby? If the answer to these two questions is yes, we'll see a way to do something new while having fun. Let's go!

But.. What's Gosu?

Gosu is a 2D game development library for Ruby and C++, available for Mac OS X, Windows and Linux. It's open source (MIT License), and the C++ version is also available for iPad, iPhone and iPod Touch. Provides basic building blocks for games:

• A window with a main loop and callbacks
• 2D graphics and text, accelerated by 3D hardware
• Sound samples and music in various formats
• Keyboard, mouse, and gamepad input

We're going to use the Ruby flavor, so we need to install the Gosu gem with gem install gosu. But first, in order to be able to use it, we need to install some dependencies. I'm going to use Mac OS X, so I only need to install sdl2 library via Homebrew executing brew install sdl2. Here you have the links to the official documentation for all OS:

• Mac OS X: Getting Started on OS X
• Linux: Getting Started on Linux
• Windows: Getting Started on Windows

Ready, steady.. let's do some code!

Ok, we have all installed. so the next step is start the development. We could use Gosu and develop our game as a simple Ruby application (without structure of any kind), throwing some files with our code into a folder, but in order to maintain a minimum structure, we're going to do it as a regular Rails gem. I'm going to name my game 'Simplelogica: The Game', so:

This generate the following basic structure:

To store all the assets that we'll use in our game (images, sounds, music..), we're going to create the assets folder in our project, with some other folders inside it (images, fonts, fixtures..). At the end we're going to have a structure like this:

We're a great developers, but if art is our weak point, to make the design of the scenarios, characters, etc.. of our game, we can go to communities of artists who share their resources to everyone can make use of them, e.g. http://opengameart.org/.

Well, let's explain very quickly the basis of the development with the help of the official Gosu Ruby introduction (you have the complete documentation of Gosu here if you want to go deeper).

Don't worry, as always, at the end of the post I'll put links to the repo with the final code to the game I made so you can see all detail

Spoiler! The examples shown here are directly extracted of the Gosu wiki. All the explanations and example codes of the next parts belongs to them.

Overriding Window's callbacks

Gwj6: out of place cacti mac os. Every Gosu application starts with a class that derives from Gosu::Window. A minimal window class looks like this:

The constructor initializes the Gosu::Window base class. The parameters shown here create a 640x480 pixels large window. It also sets the caption of the window, which is displayed in its title bar. You can create a fullscreen window by passing :fullscreen => true after the width and height.

update() and draw() are overrides of Gosu::Window's methods. update() is called 60 times per second (by default) and should contain the main game logic: move objects, handle collisions..

draw() is called afterwards and whenever the window needs redrawing for other reasons, and may also be skipped every other time if the FPS go too low. It should contain the code to redraw the whole screen, but no updates to the game's state.

Then follows the main program. We create a window and call its show() method, which does not return until the window has been closed by the user or by calling close().

The window loop it's something like this:

Using images

Gosu::Image#initialize takes two arguments, the filename and an (optional) options hash. Here we set :tileable to true. Basically, you should use :tileable => true for background images and map tiles.

The window's draw() member function is the place to draw everything, so we override it and draw our background image.

Player and movement

• Player#accelerate makes use of the offsetx/offsety functions. They are similar to what some people use sin/cos for: For example, if something moved 100 pixels at an angle of 30°, it would move a distance of offset_x(30, 100) pixels horizontally and offset_y(30, 100) pixels vertically.
• When loading BMP files, Gosu replaces #ff00ff with transparent pixels.
• Note that draw_rot puts the center of the image at (x, y) - not the upper left corner as draw does! This can be controlled by the centerx/centery arguments if you want.
• The player is drawn at z=1, i.e. over the background.

Using our Player class inside Window

Gosu::Window provides two member functions button_down(id) and button_up(id) which can be overridden, and do nothing by default. While getting feedback on pushed buttons via button_down is suitable for one-time events such as UI interaction, jumping or typing, it is not place to implement actions that span several frames - for example, moving by holding buttons down. This is where the update() member function comes into play, which calls the player's movement methods depending on which buttons are held down during this frame.

Text and sound

We could add some sounds and custom fonts using the Gosu classes Gosu::Font and Gosu::Sample, like this:

Ok, I get it, but.. how should I put all together to develop my game?

After you've tried these simple examples and have delved a little deeper into the Gosu's documentation, you're ready to code your game. The basic idea is to create a class for any resource you want to have in your game (window, sprite, player, enemy, bullet..). On the main class of the project (in my case, lib/simplelogica_the_game.rb file), you have to require all this files, and do something like this:

Then, create a file in bin folder (e.g. bin/simplelogica_the_game.rb), which is the one that you'll execute and initialize the game, with this code:

Make sure that this last file is executable (chmod +x bin/simplelogica_the_game), and try to run it by typing bin/simplelogica_the_game from console. With a little effort and some lines of code, you could have something like this running:

Please, clone my repo and try to play the game so you can see all this pixels in action! :D

I hope you liked the post, and I encourage you to begin with game development and become the new master indie developer (or at least try it with Gosu), but please, while you develop some great game, listen to this song.. So many good old memories.. Kirby for the win! :_D

Any place where I can see the result?

Yeah! Here you have the Github repo for this example, so you can clone it, change it, play with it.. whatever you want! :)

Many users have encountered a situation where their computer doesn't start up appropriately, and they can't figure out the reason behind this. While a single beep is a sign that POST is working normally, 2 beeps on startup, no display, more beeps, or no beep are considered warning signs. It indicates a problem with the system hardware that needs rectification as soon as possible.

Here we will explore what does POST and beep codes mean and how you can resolve the issues related to them. Moreover, we will discover how you can rescue your hard drive data from being lost permanently.

Part 1: What are POST and Beep codes?

To understand the no beep on startup or multiple beeps problems, we first need to know about the POST and beep codes. When a computer starts up, it runs a POST, i.e., Power-On Self Test, to check if there is a problem with the system. The moment POST detects a problem, it displays an error message on the screen.

However, if the BIOS encounters a problem but hasn't booted far enough to give the error message on the monitor screen, beep codes are used for notification. It is an audible sound of the error message. The beep codes can be very helpful in determining the root cause of the problem. And if there is no beep sound when the system starts even when you have made unsuccessful attempts to start the computer, it means there is still hope. For that case, consider using the POST test card to see the error in digital form and resolving it.

Part 2: How To Fix No beep Codes, POST, or Input to Monitor Issue?

Let's learn how to fix no POST beep codes issues on a computer.

Step 1: Assess the POST:

The first step is to check if the POST is working accurately or not. To do this, pull out the video card and again try to boot your system. During this operation, if you hear one or two long beeps, it is a sign that POST is working. The beep code suggests that the video card is missing. However, if you hear no beep on startup, it means that POST is not working at all.

Step 2: Check Connections:

At this point, ensure that all the cables, including the power cable and other connections, are intact. Check all cables that connect the keyboard, storage drive, video card, RAM, graphics card, CMOS battery, SSD, and other components. There is a slight possibility that one or more cables are damaged or soiled that is leading to the issue in the first place. Replace them with a new one and see if the problem gets resolved.

Step 3: Remove any disks or USB devices:

When there is no beep on startup, try unplugging the connected disks and USB devices. It includes the printer, USB hubs, external devices, etc. Then try booting the system and allow the system to boot completely. After that, start connecting the USB devices and disks one by one to recognize the faulty device.

Step 4: Reconnect and check power cords:

The next valid step to resolve the no beep on startup issue is checking the power cords and reconnecting them. No beep is often a sign of Power Supply Unit errors. When the computer is not getting enough power or the power flow is being interrupted frequently, the system encounters such problems.

So, check the cords and PSU to see if they are working fine. Try disconnecting the wires and UPS from the computer. Connect the power cables to another outlet for a steady flow. Replace the PSU with a new one as it will help you identify if the problem is with the Power Supply Unit.

Step 5: Identify the beep code:

Perhaps you heard the beep wrong, and there might be other beeps. Hence, identifying the beep code is a crucial step in fixing no beep on startup or more beeps issues.

Here is the entire list of Beep Codes that will have you narrow down the problem and its cause. The beep code information is also available on the motherboard or computer documentation. You can gather all the information you want on the beep codes from the document. After all, the beep codes are meant to be a failsafe for the users to help them identify the problem if the boot process doesn't finish up. If the beep code you hear in your computer is not available, then continue with the troubleshooting steps.

Step 6: Remove RAM:

In some computers, 2 beeps on startup and no display is a sign of RAM error. When the RAM is not detected by the system, it will throw this error, and you will hear two short beep sounds. It often happens when the user has connected two RAM sticks with the system. Consider removing one of them and then boot the system.

If this doesn't work, try switching the RAM stick to a different slot and again try booting the system. Repeat the same with the other RAM stick to resolve the error.

Step 7: Check CPU & its Fan:

Now, once you have checked the connections, it is time to look deeper into the problem. Start by checking the CPU and its fan. If the CPU is not installed correctly or the plastic guard is not removed correctly after CPU installation, then the system will give more beep sounds. So, make sure that the CPU is working fine, and the plastic guard is also removed.

Alongside this, check if the CPU fan is working when you boot the system. So, if you don't hear the sound of the fan running, it means that the motherboard is preventing the system from booting. The motherboard often halts the boot process if the fan is not working to prevent the system from overheating.

Step 8: Check Wires:

If everything other component is working well, then it is time to check the wires. You must have connected the cables inappropriately, or the connection might be loose. Check the cables and secure the connection by firmly pressing each cable.

Step 9: Try Clearing CMOS – Refer to your system manual:

The next fix is clearing the CMOS. It means that you will reset the BIOS settings to default. To do this, we propose that you refer to the system manual or get in touch with the system support team to learn how you can reset the CMOS.

Once the CMOS is reset, you can reconfigure the BIOS according to the hardware, if required, and boot the system normally.

Step 10: Bad motherboard, CPU, RAM, or power supply

If all the above tips failed to resolve the no beep on startup issue, it is most likely that your computer's motherboard, CPU, RAM, or power supply has failed. Hence, the final step will be replacing these components or get your system serviced from professionals.

Part 3: How to recover data what if there is a problem with the hard drive?

In the worst-case scenario, when there is no beep on startup, it might be the hard drive interrupting the system hardware from running smoothly. At this point, the users will get worried, thinking they might end up losing their system data of this. But don't worry; even if you somehow end up losing files, Recoverit Data Recovery software can still help restore all lost and deleted files. It can assist you in performing recovery from a logically failed, damaged, or corrupted hard drive.

Download, install, and set up the software carefully on your PC or any other PC in working condition. Once the software is ready for use, follow the steps below:

Step 1: Select a Location:

Step 2: Scan the Location:

By default, Recoverit will perform an All-Around Scan of the hard drive to look for the lost and deleted files. The scan results will start appearing on the screen as the scan moves forward.

Usually, it only takes a couple of minutes to finish the scan. But if there are many large-sized files on the drive, the scan will take a while to complete.

Step 3: Preview and Save:

Once the scan finishes, start selecting the files that you want to restore and have a preview. You can choose multiple files and hit the 'Recover' button to save them on your system.

The Bottom Line:

Hopefully, the steps we provided to fix the beep issue will come in handy, and you will be able to get rid of the cause of the problem.

In the end, when you can't find a solution to the problem, data loss becomes inevitable. However, whether it is no beep on startup issue or the system has failed, Recoverit Data Recovery software serves as the perfect solution to data loss problems. With the help of this professional tool, you can ensure that not even a single piece of data will get lost from your computer. Don't forget to tell your friends and family about Recoverit.
