Android: how to create a loading screen – Part 2
Posted by Dimitri | Filed under Programming
This is the second tutorial from the post series that explains how to code a loading screen on Android. The first one can be found here. This post has a similar approach to the previous one, except this time, instead of using a AsyncTask to execute code on the background thread, a Thread and Handler objects are going to be used to achieve the same results.
The Activity featured below is somewhat similar to the first post, except this time, the UI rendering related functions calls will be more scattered throughout the Activity’s body. Additionally, the Runnable interface is going to be implemented multiple times in the below code. Not only that, but now it’s necessary to “kill” the thread manually after the code executes, a task that is handled automatically by the AsyncTask class (see this thread for more info).
All code has been developed and tested in Android 2.1, and is available for download at the end of the post.
Android: how to create a loading screen – Part 1
Posted by Dimitri | Filed under Programming
This is the first of three Android post in a series that explains how to code a simple loading screen that shows the progress of operation before the application’s View is loaded. This first tutorial objective is to create this loading screen in simplest way possible. The code featured in this tutorial has been developed and tested in Android 2.1, but it should work without much modification in later versions. All code featured in this tutorial is available for download at the end of the post.
Because of the nature of the Android operational system and the Activity stack, there’s no way to precisely determine the loading progress of an Activity. That’s why, in the below example, the Activity is going to be started, but instead of loading the standard View, it will load a ProgressDialog object and simulate a computationally heavy process on a background thread right on the beginning of the onCreate() method.
Unity: How to playback fullscreen videos using the GL class
Posted by Dimitri | Filed under Programming
This Unity programming tutorial explains how to use the immediate mode rendering available at the GL class for the playback of video files. There is already another post here on 41 Post that shows how to do the same thing using GUITexture component. However, in this tutorial, a quad is going to be rendered and the video will be played at its texture.
Not only the steps required for achieving fullscreen video playback are going to be explained, but how to properly scale the video based on the screen dimensions is also featured in this post. Warning: this tutorial works only with Unity Pro because the free version doesn’t support video decoding. This post has been created and tested in Unity version 3.4. At the end of the post, a Unity project featuring all the code explained here is available for download both in C# and JavaScript.
Android: Detecting Double Tap Events
Posted by Dimitri | Filed under Featured, Programming
This Android tutorial explains how to create an Activity that “listens” to double tap events. Doing that isn’t as trivial as getting a single tap from the screen, however writing a code that registers when the screen has been touched twice isn’t complex either. The example featured in this post works on the emulator and on a real Android device.
To implement the double tap, some classes and interfaces are going to be needed, but it’s best to show the example Activity code before explaining each one of them: (more…)
Unity: Scaling the GUI based on the screen resolution
Posted by Dimitri | Filed under Featured, Programming
As hinted by other posts, here, you will find how to properly scale the GUI elements based on screen resolution. As one may have noticed, Unity doesn’t scale the GUI elements based on the screen resolution, requiring a script to do the job, which is explained in this post. I will assume that the reader already knows how to create and render GUI elements in Unity using the MonoBehaviour’s OnGUI() function and GUISkin objects.
The best way to explain how to properly scale a GUI element is through an example. That said, for this post, let’s assume that we wanted a yellow rectangle to be rendered at the top left and bottom right corners of the screen, like this: (more…)
