Unity: expandable GUI Window
Posted by Dimitri | Mar 6th, 2013
This Unity programming tutorial shows how to create a GUI window that changes between two pre-determined sizes, in other words, an expandable GUI window that can be shrunk down, back to its original size. The code on this post has been developed using Unity 4.0.1f2, and an example project is available for download at the bottom of this page.
Unity’s GUI windows elements are very useful, not only because they can visually group various GUI elements, but also due to the possibility of repositioning it on the screen. For that reason, the script features some additional logic that allows for the windows to be resized at the correct position on the screen, even if it has been dragged by the user.

Android: Change color of the standard button inside Activity
Posted by Dimitri | Feb 13th, 2013
This post explains how to change the color of the standard Android button. It also shows how to change the color of the text inside those buttons. It goes into detail on how to create a ColorFilter effect that changes the color of the button using three different approaches . The code featured in this post has been tested on Android 2.1, 2.2, 2.3 and 4.0.
Before starting, a little advice: know that changing the color of the standard Android button through XML is an easier and more straightforward approach. For that, please refer to the link Custom color buttons for Android (9-Patch). If the button color isn’t going to be changed after the application is initialized, then use XML. If that isn’t the case, then do it programmatically, which is what this tutorial focuses on.
So, here’s the code: Continue reading: “Android: Change color of the standard button inside Activity”
