June 25th, 2011: Introducing FTPUploader ¶
Hello everybody… I know it’s been a long, long time. But, look at the bright side: exams are finally over, I can write more again, I got my Abitur… and a lot of free time. So I went through old projects to see if I can find anything interesting. And I found something very interesting indeed and thought of sharing it with you guys.
November 18th, 2010: Sudoku App v0.1 beta ¶
I’ve uploaded another app; this time it’s Sudoku which includes following features:
-
Auto-Save
If you can’t finish one game, Sudoku saves the current game on your hard drive for next time automatically.
-
Check
A built-in checker can inform you of all anomalies you created.
-
Notes
You can assign notes to each field if you aren’t sure.
-
Tips
For the rare occasion if you are completely lost… Simply get a tip. Only works once in a game, so use wisely.
I’m also proud to mention that you can play this puzzle game without the keyboard (which is great itself, because you don’t have to swap exhaustingly between keyboard and mouse). You can select the tiles by clicking on them. You can edit notes of a tile by double-clicking on it. You can edit the number of a tile by scrolling your mouse wheel. See? It’s simple. Wheeee. Just give it a try!
It’s still in beta phase, though, because there are lots of things to improve.
November 13th, 2010: Flipping elements with WPF ¶
ForgottenTime 3 is available for download now!
Have you already seen ForgottenTime’s new flip animation eye candy? If not, it’s about time! It took me several days to figure out how to do it…
My first thought was to find out how to do a 4-point-tranformation of a given image. (See figure on the left.) It’s no problem to create an “screenshot” of a UI element and I could easily calculate the four vertices of the transformed image (with given angle and a little bit trigonometry) and transform the original screenshot via the function to achieve a 3D effect. Unfortunately, there’s no (easy and fast) way to do that in C# and Windows Presentation Framework, so I had to think of something else.
After my research on the Internet I came across some official demo WPF applications, also using advanced UI techniques such as flipping. So I dug into the code to find out how they did it. As it turned out, they were using 3D graphics.
