When I started using C#, mainly because of XNA one of the things I got used to write is foreach loops instead of for, seemed easier and it’s a much cleaner code. Doing almost the same thing as a for loop I never really bother to see the differences, almost everyone in their XNA examples used it instead. Today I decided to see the differences between them: FOR int[] values = new int[1]; int total = 0; for(int i = 0; i < values.Length; i++) { total += values[i]; } FOREACH ...

As most developers do I spend a lot of time programming. Most of us has made some sketches for prototyping games, yes, the ones no one else can understand except for ourselves. I always liked drawing and 3D modeling but I was never very good at it. I was just cleaning up some stuff on my pc and found a folder, god most of this stuff I made is UGLYYYY lol. ...

Lately all my free time has been spent adding new features to Basalt and developing Sapphire. Some months ago, I started building Sapphire, a 2D editor for helping me creating to create my maps. Unfortunately I made a bad choice and decided to integrate XNA with Windows Forms, although I managed to do it it was a real pain to add something simple and eventually I dropped it. Here’s a screenshot of the previous alpha version: ...

Frame rate or FPS, how it is most commonly known is a way for you to know how many images per second is you game drawing. The more the better. Less then 30 and you start to see hiccups. So how can you measure your frame rate in XNA? Inside your game1 class declare these vars: SpriteFont _spr_font; int _total_frames = 0; float _elapsed_time = 0.0f; int _fps = 0; On function LoadContent() do // Put the name of the font _spr_font = Content.Load("kootenay"); you have on your project On the update pump do: ...

Although the title says XNA log file this is actually a C# log file, I’ve just thrown this title cause lot’s of people search for xna log instead of C# log file. Many have asked me why take time to do a log file when you can throw exceptions when something goes wrong. Well the answer is simple, to keep track of what’s happening, log steps, write to the file exactly what when wrong even if you are on Release mode, and more, if someone complains the game is crashing you simply ask for the log file and see what when wrong. ...

I am definitely a fan of ATI cards. Had a few Geforces but didn’t liked them very much. I actually noticed image quality decrease when switching from an old Radeon 9800 to a Geforce 8k something. I’m very happy with my Radeon 4890, now for the downside, PerfHUD, a very handy tool for Game Developers is only available for NVIDIA chipsets and although ATI has it’s own GPUPerfStudio it’s not the same thing. Anyway for those who have one and are developing for XNA you may have noticed that it doesn’t run PerfHUD out of the box. You will get an error, something like: “This applications is not configured for using PerfHUD. Consult the User’s Guide for more information” ...

Epic decided to offer Unreal Engine 3 for free to non-commercial applications. Sounds kind of weird considering it’s one of the best and most licensed engine out there, but maybe the recent release of Unity 3d free for all uses made them consider this option. Named UDK (Unreal Development Kit) you can download it here and have access to all tools and features that the full commercial Engine contains, well, except for the source code of course. This opens a lot of doors to students and indie hobbyists as me. I just can’t wait to have the time to get my hands on this. ...

I recently needed to force a WMV to download using Apache. The default behaviour for most browsers is to try to open the movie inside the browser itself. This works fine if the person has the plugin otherwise we just gonna have a blank page. Also for huge WMV is easier to download the file for later viewing. So just place this on your .htaccess on the root of your website. ...

I decided to make a game for the xna7day competition, in which we have to make a game that only uses 2 keys, so absolutely no analog input and it has to be built on xna of course. This is a great opportunity to test my engine Basalt. I decided to make a puzzle game, basically the rules are the same of a 3 in line game. This is what I have so far. ...

Making a clickable text or image is easy, just add the <a> tag surrounding it. But this doesn’t work with divs and sometimes we need a whole div to be clickable and not just text. The following code is for JQuery but switching it to your favorite JS framework should be very easy. First start by adding this to your div <div class="clickable"> </div> Now a little css to simulate the pointer on that div ...
