Not much happened on the game programming front, but at least I made an effort to do something for the production. While I was away from this project for a few weeks or so, I recently received some new graphics for the game. It wasn’t more levels, but graphics for a new front end. Saul Cross designed a great new logo for the title screen. So what happened this week? I programmed a front end and bolted it to the game, itself. Hope you like the result.
While I am waiting for the new level maps, I will be working on the order of alien attack patterns according to levels, and of course re-use the test level’s map and setup different colour schemes for each level. Each alien attack pattern consists of 26 bytes, so hopefully I should have enough memory to store compressed levels of each map, then extract each level to address $4800-$5800 (since $5800 is the start address of the game’s code). Each level should not exceed 320 4×4 blocks in height, as at the end of the 320th block row a level complete is automatically detected. 🙂
For now, here’s the result of the title screen – although it is not official at the moment 🙂 Enjoy the video.
