Android: rendering a path with a Bitmap fill
Posted by DimasTheDriver | Filed under Programming
This Android tutorial shows how to render a Path that is filled by a Bitmap and displays stroke in a different color. It also explains how to manipulate the texture coordinates to make it independent of the position of the path, just like a mask, but without using any of the PorterDuff rendering modes. The code featured in this code was created and tested on Android 2.1, both on a real and at an emulated device.
Here’s a video of the example application in action:
If you can’t play the video, don’t worry: there is a screenshot of the application at the bottom of this post.

Unity: Making a simple audio visualization
Posted by DimasTheDriver | Filed under Programming
As stated in the title, this Unity programming tutorial shows how to create a simple audio visualizer. This post focuses on explaining the necessary requirements in obtaining the audio data from the current music being played, and how to process this data to create a audio visualization. It won’t have detailed explanations on how to create a specific effect for an audio visualization. The code featured below and the example project were created and tested in Unity 3.5.2 .
For this post, the audio spectrum data will be displayed as a line using a LineRenderer component and will also feature some cubes that will fall from the top of the waveform, much like the little white bars above the spectrum found on the Windows Media Player “Bars” visualization. However, this visualization will be 3D and not 2D and will render a waveform and not bars.
To achieve that, a script and the following elements will be required: Continue reading: “Unity: Making a simple audio visualization”
Unity: Creating GUI transitions
Posted by DimasTheDriver | Filed under Programming
This Unity scripting tutorial shows how to manipulate the GUI system origin to create an animated transition, so you can make your GUI’s look more interesting. To keep things simple, this post shows how to create an horizontal transition between two Text Areas using a couple of buttons. All code featured below is available for download at the end of the post.
To achieve an animated transition, the origin of the GUI system must be manipulated. This is done by changing the elements of the matrix that sets the rendering reference point of the GUI elements. Conveniently, Unity allows us to do that by manipulating the GUI.matrix values. So, the script requires a Matrix4x4 object. Also, to make the code more readable, a Vector3 is going to be created, also making it easier to translate the GUI system origin. Here’s the script:
