From Richard's C64 blog!
25th March 2017
It has been a very long time since the last time I was working on this space shoot ’em up. Probably due to the long term lack in motivation to code a new game. Also due to getting sidetracked with other tasks as well. Not, to mention the organizing of the SEUCK Compo 2016/17, and getting the prizes done quickly before my holiday ended last week.
Now finally I have returned to this game project. Also I have migrated this game project over to Arthur Jordison’s CBMPRGStudio V3.10.0, a great C64 programming suite on the PC. Come BASIC or assembly. :). I have renamed the game project Cruiser X-79.
A lot of changes to the code and also music has been made, although I don’t really have anything specifically new to show you at the moment. The same graphics, and also the same sprites are currently used. However the game features new music, which I think works quite well with this game project so far.
So then, what things have been going on this week. Well, for a start off, after the migration of the code and data into CBMPRGSTUDIO V3.10.0 (As I promised Arthur, I create something using his C64 development suite). I created some subroutines, which perform a check when is the best time to spawn aliens. Only a small simple test has been made to test the alien spawning. Basically, check to see if any aliens are offset in the game. If so, then wait until all aliens are out of the screen (or dead). Then set the timer to wait for new aliens to spawn.
Another subroutine created, linked to enemies, are based on enemy movement. I created some checks to see which direction the last alien movement should be, and also which part of the screen should the alien exit. Should an alien leave the screen going a certain direction, the subroutine automatically kills that particular alien.
The video below shows the latest ongoing progress of this game project, which will be released at The New Dimension games division on the downloads page – for absolutely nothing. The game design isn’t all that exciting at the moment. No change to graphics or sprites at the moment, but eventually it will happen. Aliens only move straight formation, but I will do better ones in the future. Enjoy the video of the preview and expect to see more progress during the times ahead 🙂
