I’ve seen this quite a bit around on XNA forums and got 2 emails last week asking about this: I want to make a 3000×3000 grass background by tiling this small grass image I have. Should I make one big image or should I make a for cycle drawing the image (3000/TileSize) times? My answer is neither of them. The big image has a huge impact on every Draw and more, you are limiting your map to the max Texture Size the graphic card can handle....
Note: 22/04/2013 – Due to popular request I made an article about achieving this effect in OpenGL Independent Resolution Rendering?? What’s this all about? Basically a way of not caring what you resolution is. Ever had Gui elements misplaced because you changed the resolution? Or getting out of the screen? If you are doing a game on Xna just for Xbox360 you can basically use a 1280×720 base resolution and the Xbox will scale the game for you making the proper Letterbox....
So I was watching Microsoft Mix10 and while talking about the new Windows Phone 7 Series, Scott Guthrie announced the availability of the Windows Phone Developer Tools CTP. What? But like now now? I went to http://developer.windowsphone.com/ and XNA Creator’s Club and there it was. The packages contains: A CTP of the new Visual Studio 2010 Express for Windows Phone Tools and framework to develop Windows Phone applications and games with Silverlight A CTP of XNA Game Studio 4....
Damn you should see my face when they told me we won the competition XNA Pizza Night 2010 at Microsoft. Originally we developed Vizati to enter Dream Build Play 2010. We started developing the game on the beginning of February and during that month we discovered another competition would be held near Dream Build Play deadline. We went there with the same demo we sent to DBP. The audience really liked the game and we got very positive feedback....
Rita and I have been working on a demo for entering Dream Build Play competition and today she has finally finished the teaser for Vizati. It’s our game for entering the Dream Build Play 2010 competition and XNA Pizza Night. We started working on this around 3 weeks ago so it’s still an early draft from our vision of the game. Vizati is a puzzle game made by Different Pixel for Dream Build Play 2010 in which you need to connect the little vizati stones by color....
It’s been a long week. Even though I’ve always pointed to a make a very simple game for Dream Build Play so that I may actually have the time to finish it I just lost almost two day doing something to show for about 3 or 4 seconds per level. Discussing how we should make our puzzle appear and disappear between each level we decided that a particle system or an effect of such nature would be nice to show apart from some fading or something on the puzzle itself....
Well the title is an Homage to James Silva‘s I MAED A GAM3 W1TH Z0MB1ES!!!1 I’ve been really busy with my Dream Build Play game lately. Although being a simple game somethings always turn out to be harder that we initial think. I’ve been debating myself with some bugs on my engine, had to redo tons of code yesterday due to XBOX360 compatibilities (should have tested earlier :P). Two days ago Rita started doing the assets and it’s looking really good....
One of the things I realized is very handy when prototyping or debugging is to draw a line on a specific location. Like drawing lines around collision boxes to see if your character is making a proper collision. For my games I’ve made a small LineBatch. Basically LineBatch uses a SpriteBatch to draw the lines by stretching a 1×1 white Texture2D to your line size. You can give it 2 points ( start and end point of course) and a color....
I know there’s lot’s of this stuff over the internet but I keep bumping into people asking for this. A way to easily switch from a Game Screen to a Menu or Options without having tons of flags and “if” clauses on the class Game. I’ve made a small project with a Screen Manager. The ScreenManager is static and can contain Screens. Instead of having typical Draw Update functions drawing SpriteBatches on the Game class we should have something like this:...
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...
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....
