SpaceWars Update: Working on port to OpenGL!! July 11, 2009

Posted by tjerkw in Uncategorized.

Okay i really needed to update this blog. So here it is.

Short summary: i was busy with other things the last few weeks,  i decided to port the game to opengl for performance

Firstly: i did not have a lot of time for my game, i am almost done with my master thesis and it still needs some work, also i did several job interviews the last weeks in order to find a good job. And another thing i was busy with: i needed to migrate my server, that was a few days of work.

Anyway about the GAME!  The game is getting better however i am not satisfied with the performance. The performance is oaky when there is not a lot happening on the screen. However things become laggy when there are multiple ships and explosions. Therefore i decided to port the whole game to OpengL! This will make the game a lot faster! This choice requires a lot of work on the painting code of the game. However i think i will manager. The users will not see any new things in the game, they will only see that the game is a lot faster.

After that i am going to add more levels and more cool stuff (maybe 3d elements?). Anyway i will keep you updated!


Game Update: Better Controls June 16, 2009

Posted by tjerkw in Uncategorized.

A new update is available on the market. If you’re on an android phone: goto the market to check the game. Otherwise check the game in the market here. It has the following improvements:

  • Better controls with accelerometer
  • Joystick visualizes accelerometer effect
  • Joystick can be used by dragging it on the screen (overrides accelerometer)
  • Smaller game size: decreased the size of some sprites and did some other optimizations (4.7MB after unpacking, so decreased by almost 2MB)

The game is still to easy but the priorities now are the controls. I think they work nicely now and its time to make the levels more interesting. Coming closer to the final game!

By the way: some users report that the boss cause the game to lag. I do not have this problem on my HTC Magic. Maybe this problem is HTC Dream (G1) specific? Can somebody acknowledge this?

The new onscreen joystick.

The tutorial for newbies.

SpaceWars Beta released on Android Market! June 10, 2009

Posted by tjerkw in Uncategorized.

Yes: finally the time has come: a Beta Version!

I tested the game a lot on my device and decided it was a good time to release the first beta version on the android market (link to market for android users).

I released the game in the middle of the night at 02:30 ;-). It was downloaded more than 500 times already!

This version is free and mainly released to gather user feedback which can be used to make the game even better! I already got some useful feedback.

I really appreciate the feedback:  Thanks everybody!

Greetings from Tjerk!

A lot has happened the last 2 weeks. The most important thing: i got my HTC Magic!!

Here is a demo of my game. There is a bug with sensor+sound but i have fixed it this evening by applying damping on the sensor values. More info in the video:

I hope to add an alpha version to the android market this week!

  • Code logic for boss-enemies
  • Implemented one new boss enemy (See screenshots)
  • Implemented game logic for levels (boss health barr, exit when level is completed)
  • Added a level-progressbar to the right which shows how far you are in a level
  • Added new graphics for messages during gameplay (see screenshots)
  • Now game loading is done in seperate thread, and one sees a loadprogressbar before the game is loaded
  • And more (which i cant remember 🙂

The initial work for multiple levels and multiple dificulties is done. So thats next on my list.

Here a video of the game running on the G1. Thanks to Luís Abreu for posting it! The video also shows a bug (when first pressed the play button)… so it needs some work.

Yesterday I did a lot of development for the android game. The new features + screenshots are listed below:

  • Game renamed from AirAttack to SpaceWars: main reason is that the ship flies in space 😉
  • Created an intro/splashscreen animation when you start the game
  • Created new artwork for the menu
  • Created animations for the menu (the buttons fade in & and animation when pressed)
  • Created sprites for the bullets: bullets are now shiny, and they have different colors!
  • Created a new weapon: A laser weapon, everything that hits the laser is killed. Really looks neat!

Some screenshots:

And a youtube video of the game running on an emulator (on a slow pc, thats why you see the hickups). In the end of the video you will see the laser weapon in action!

The video is made with my digital camera in potrait-view.. So thats why it is rotated 90 degrees.. so rotate your head when viewing the video 🙂

BTW: I am searching for someone to run the app on a real phone a make a video of the game: too see the accelerometer controls working 🙂 Anybody interested? Contact me: tjerkw@gmail.com, and i will sent you the APK (for android 1.5)
