+atari2600land Posted October 10, 2019 Author Share Posted October 10, 2019 So playing with the code again, I discovered that I will only have room for 20 levels, not the 25 I had thought before. I could fit 25 if I make the level data smaller, but then it looks all weird, so I am going to go with 20. I want to add a secret level select code, and I'm having trouble with it. rem temporary level select code for testing only. if joy0right && !keygot{2} && levelnumber<$20 then keygot{2}=1 if !joy0right && keygot{2} then keygot{2}=0 : dec levelnumber=levelnumber+1 if joy0left && !keygot{3} && levelnumber>$1 then keygot{3}=1 if !joy0left && keygot{3} then keygot{3}=0 : dec levelnumber=levelnumber-1 I can't make the levelnumber variable work correctly. I put this before the title loop and before the level data getting code, but it won't work right. What do I have to do? levelnumber=converttobcd(levelnumber) I also thought of a cool idea I would like to implement but don't know if I could: Have the score be a scroll, like from a lost treasure map or something (see crude pic below). I am wondering if I could do that somehow. Quote Link to comment Share on other sites More sharing options...
+Karl G Posted October 10, 2019 Share Posted October 10, 2019 Are you treating levelnumber as a bcd variable throughout your code? If you set it that way initially and do all addition and subtractions with "dec", then you shouldn't have to use the conversion function to begin with. I would think that if you run the conversion function on a number that is already BCD or has already been converted to BCD, then in some cases it would corrupt the number. E.g. if levelnumber starts out with a value of 10, and you run converttobcd, the value becomes $10. If you run it again, it is assuming that you are starting with a binary number, so after converting again, the value would be $16. In most cases, I think the easiest thing would be to start with a BCD number, and have all addition and subtraction operations be in "dec" mode so that you never have to convert. 1 Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted October 10, 2019 Author Share Posted October 10, 2019 OK, I think I fixed that problem, but I have another one. I tried putting in a scroll image as a banner, but it gave me this error message: *** (): INFO, GFX Block #3 starts @ $E000 scroll01 *** (): INFO, GFX block #3 has 1800 bytes left (225 x 8 bytes) Why won't it put the whole image in if the GFX block has 1800 bytes left in it?

+SmittyB Posted October 10, 2019 Share Posted October 10, 2019 Is there more to that message? I wouldn't say that's an error just looking at it, but.... As your graphic is 16 pixels tall it's imported as 2 graphics. 160A graphics are 2 bits per pixel so a byte defines 4 pixels. 124/4 = 31 bytes, 31 * 2 zones = 62 bytes for that image. 256 - 31 = 225 so that tells me it's only imported the first half meaning you may have used incgraphic rather than incbanner.

+atari2600land Posted October 10, 2019 Author Share Posted October 10, 2019 I fit it in! I had to split it into 2 different 124x8 images though, it wouldn't let me make it a banner for some reason. 5 Quote Link to comment Share on other sites More sharing options...

+atari2600land Posted October 10, 2019 Author Share Posted October 10, 2019 The coral/sub collisions aren't working. I don't know why. I am calling them. Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted October 11, 2019 Author Share Posted October 11, 2019 As it turns out, the sub/coral collisions weren't working in the boss stages. I figured out the cause by remembering the boss stages use a different character set. Everything is fixed now. I have 166 bytes left in DMA hole #0, which should be plenty of room for a bonus stage song. I made an ending song and a boss song while I was at it. gosub2019october10v2.zip 2 Quote Link to comment Share on other sites More sharing options...

KevinMos3 Posted October 12, 2019 Share Posted October 12, 2019 Great job. The only complaint I have is that it's hard to tell what's going on in the game over screen. The sky looks very green and blends in with the captain. If you're using a color in the Ax or Bx range, it's going to look very green on a lot of setups. I recommend not going past the 9x range for blues especially for a sky color. Quote Link to comment Share on other sites More sharing options...
gambler172 Posted October 13, 2019 Share Posted October 13, 2019 Hi Chris great work....works well on real hardware...why not go upnto more KB???This would mean more space for more levels ? Would it be possible to ad d another boss instead of octopus for 2 times? Maybe a giant jelly or a shark? This are just suggestions...the game plays very well. greetings Walter Quote Link to comment Share on other sites More sharing options...

KevinMos3 Posted October 14, 2019 Share Posted October 14, 2019 (edited) This is what it would look like using 9A for the sky: Compared to the current color in 2 different emus. Many TVs will look somewhere between these. Some will lean more toward the picture on the left, but that's pretty much the best you can hope for. Some of my older TVs definitely lean more toward the in-between of these pics or more toward the right. I've worked with colors and how they look on many different TVs. Just saying that you don't really want to go past the "9x" range for sky blue. The "Ax" range can work depending on surrounding colors, but it's likely to appear too greenish (though suitable for water). The "Bx" range will definitely be too green for sky. Unless it's a shared color with something you want to appear green, but in that case, "Ax" would be a suitable compromise.

TIX Posted October 14, 2019 Share Posted October 14, 2019 yeah, I got the right hue in Altirra ! Quote Link to comment Share on other sites More sharing options...
KevinMos3 Posted October 14, 2019 Share Posted October 14, 2019 I just noticed the pic of the game over screen in post 200 on the previous page. Not having the sky a different color (same color as the water) makes it look less boxed in. I kinda think that looked better. Here it is with the 9A color used to highlight some of the waves/spashes while the sky is removed to avoid the boxed in look, but keep the extra color detail. The man's jacket is B4 in this mockup. It could go one lower to give more contrast with the water, but I don't have my actual 7800 color pallet for my art program available right now. I'd avoid any luminance 2 or lower if you also have black though (as you do here), because on a lot of TVs a value of 2 or lower looks almost indistinguishable from black. 2 Quote Link to comment Share on other sites More sharing options...
+Trebor Posted October 14, 2019 Share Posted October 14, 2019 14 hours ago, TIX said: yeah, I got the right hue in Altirra ! Altirra maybe be leveraging the factory/cool appearance of the palette (Palette customization and selection is available under Altirra due to a number of factors). Regardless, take note of the attachments. 9x remains distinctively blue, but for many values of Ax, it can look more green than blue over consistent system running time. COOL: HOT: The 7800 8BitDev site provides a more detailed explanation respecting the 7800 palette; including the gif linked below to help with visualization of what transpires. Truth is most colors stay consistently near the same, visually. Ax is one range in which the change over time can be significantly noticeable. http://7800.8bitdev.org/index.php/File:YIQ-7800-warmup.gif 3 Quote Link to comment Share on other sites More sharing options...
RevEng Posted October 14, 2019 Share Posted October 14, 2019 KevinMos3's version of the screen does look better. Sort of an "endless sea" effect. It could be enhanced further if you took a wave sprite or two and plotted waves in a bunch of locations around around the screen. 2 Quote Link to comment Share on other sites More sharing options...
+atari2600land Posted October 14, 2019 Author Share Posted October 14, 2019 OK, I will change it back to the background being the same color as the water when I get to it. Quote Link to comment Share on other sites More sharing options...

TIX Posted October 15, 2019 Share Posted October 15, 2019 If you choose to go that way (personally not a fan), we must at least define the waves better.. Quote Link to comment Share on other sites More sharing options...
+Defender_2600 Posted October 21, 2019 Share Posted October 21, 2019 Very nice concept, guys! I was thinking it could be a nice option vary the background color every 32 pixels to simulate the depth of the sea and the seabed : 2 Quote Link to comment Share on other sites More sharing options...
