Re: 3D Star Raid - Star Wars clone

Here's an updated version of 3D Star Raid. It has a few bugs fixed but the most noticeable difference is that the second stage now has the same challenge to shoot a set number of towers for a bonus as the original Star Wars game had. A message at the top of the screen tells you how many towers left ...

Re: 3D Star Raid - Star Wars clone

Thanks for the artwork. The first stage does have a quota of tie fighters to shoot before you go to the next stage. The other two stages both use a countdown before moving to the next stage or reaching the exhaust port.

3D Star Raid - Star Wars clone

I've been working on a ZX81 version of the 1981 3D Star Wars game. It includes all three levels and the even the zoom in and out cinematics. The trench stage is slower than the others, but it is asking a lot from the ZX81 to draw the trench in 3D. The game runs with colour and sound if you have a ch...

3D Battlezone for the ZX81

I've finally gotten my version of the old arcade game Battlezone complete. Like the arcade version, it's in 3D, however the tanks do not move or shoot. Only the homing missiles are a threat to the player. You get two missiles coming at you of difficulty level two, but only one on level one. The leve...

Valley of the Kings 3D game

Here's a game I've been working on for over a year, Valley of the Kings. It uses a 3D drawing system that can scale and rotate, so you can look around a 3D landscape and pick up objects. This game has three rounds consisting of three stages. Grab the Pharaoh's treasure, steal his chickens and each r...

Re: Machine Code Spirograph program

The "PLOT" basic ROM command jump is not use... great job.
Yes, I used my own quick plot routine that I wrote some years ago. I used the same routine in the version of the Arcade game 'Berzerk" named Berzxerk as it was for a ZX81.

Machine Code Spirograph program

Here's a quick machine code project. How about a spirograph program? The options screen is in Basic. Select your parameters for the spirograph you want to see or press R for a random series of screen savers. If you select parameter input, the program will draw your spirograph and then redraw it afte...

Re: Doom 3D ZX81 style

I do have a version of that demo which has fully textured walls, which sample correctly according to distance / angle. However, getting it to handle moving & scaling enemies (ala Wolfenstein) was getting difficult and slow, and I felt that a simple ‘find the key to escape’ game wasn’t much fun. Was...

Re: Doom 3D ZX81 style

Some time ago I coded a ray-casting engine in the style of Wolfenstein 3D. It is probably too slow in its ‘textured’ form, but like yours, could work in wireframe… Wow, that makes my efforts look pretty lame. I was hoping to get similar speed out of the system but it's pretty slow and only draws a ...
