A few suggestions: Allow moving sideways (Fire + Left/Right) I don't know how you determine the color of a wall (there seems to be some logic behind it), but it would help navigating and mapping if the colors do not repeat on consecutive walls. The walls sometimes look lacerated at top and bottom, can that be avoided? The change exploits a visual artifact on CRTs that produces nice vertical hairlines between blocks. This gives an impression of much higher resolution. I don't know if the effect is as visible on PAL CRTs. A few clumsy pictures from my NTSC CRT enclosed. I like the idea of strafe but have other plans for the fire button. will try it and see how it feels. The map is evolving to make navigation clearer (but not too clear). Wall laceration is a consequence of cheating on the math, am looking at ways of improving it. Moria is old and crumbly after all.... 6 Quote Link to comment Share on other sites More sharing options...

This works in Stella too if you enable TV effects. 9 minutes ago, rossum said: Wall laceration is a consequence of cheating on the math, am looking at ways of improving it.

Maybe you could have left/right be for rotating left and right, and down+left/down+right be for strafing left and right. So you won't be able to back up without turning around. Just an idea.

7800Knight Posted July 7, 2021 Share Posted July 7, 2021 Speak friend and enter! I'll be honest - for a system meant to play primitive games like Asteroids and Space Invaders, this is amazing. I liked the 3D maze effect! Quote Link to comment Share on other sites More sharing options...

I can see that the pics have wall steps of 4 dots and sometimes 1 of those dots is turned off to make the vertical black lines. Can you explain (or point to an explanation) how this works? Thanks.

Thomas Jentzsch Posted July 8, 2021 Share Posted July 8, 2021 The dots are not turned off. The lines are solely resulting from flickering on a CRT. Quote Link to comment Share on other sites More sharing options...
stepho Posted July 8, 2021 Share Posted July 8, 2021 ok, but I still don't know what's happening. Can you go into more details. Quote Link to comment Share on other sites More sharing options...
Thomas Jentzsch Posted July 8, 2021 Share Posted July 8, 2021 I don't think the reason has been fully explored. The vertical lines are there where two interlaced lines meet. I suppose the change from bright to dark and vice versa isn't spot on. So when a horizontal line ends, it ends slightly earlier. When it starts, it starts slightly later. And the resulting gaps form the vertical lines. If you use Stella, you can experiment with the various TV filtering presets. Or switch to Custom preset and play with the TV effect parameters. You can do this live by selecting any setting via POS1/End hotkeys and changing it via Page-Up and Down. Quote Link to comment Share on other sites More sharing options...
stepho Posted July 9, 2021 Share Posted July 9, 2021 Thanks. I still don't understand but at least I'm in good company. Perhaps it's something to do with how fast the TIA can change the signal level or how fast a typical TV can follow the change. After all, TV's are designed for continuous tone images rather than sharp edges. Cleverly exploited though. Quote Link to comment Share on other sites More sharing options...

Definitely the latter. 2 minutes ago, stepho said: After all, TV's are designed for continuous tone images rather than sharp edges. Yes, the bandwidth of the analog signal is limited. Also the cathode ray cannot change infinitely fast. I suppose the effect varies quite a lot between CRTs. Probably it is even more pronounced on bad ones. 3 minutes ago, stepho said: Cleverly exploited though. AFAIK @johnnywc was the first who used this effect for the bricks in Zookeeper. 2 Quote Link to comment Share on other sites More sharing options...

Glenn Main Posted July 5, 2022 Share Posted July 5, 2022 This is a really nice thing rossum, and a sure surprise for the Pong and Combat enthusiasts. Given your technical acuity, have you built your time machine yet?! 1 Quote Link to comment Share on other sites More sharing options...

Bomberman94 Posted June 10, 2023 Share Posted June 10, 2023 Found this … again. This game has great potential - maybe @rossum you‘re willing to add new things? Would be fantastic! 3 Quote Link to comment Share on other sites More sharing options...
