Nice, but you lose 30 Sprites. 😬

was8bit 2019-01-28 13:24

Thanks :)

Yes, but you could always trim it back to 10 and it would still look Ok :)

It also uses 15 character images ....

The parallax stars in my Star Scroller demo use only one BG and one character image. But it works with horizontal scrolling only, because it's made with raster interrupts.

For vertical scrolling it's maybe better to use both BGs for parallax and sprites for additional HUD info (score, lives).

Yes, I've looked at your code, it's a very awesome effect :)

I was going for an approach that a beginner might be able to do... your code is rather advanced.. the full screen code is as well... now i know in my code I use COPY which is advanced but when putting together learning material I like adding one "Easter Egg" suprise to spark their interest... the rest of my code should be ok for those From original LowRes who are now making some programs in NX...

Just really wanted to put something together to catch people's attention :)

And to anyone with artistic skills... PLEASE copy this code, remake the spaceship, and post your artwork so we can all enjoy it :)

My spaceship needs your help!!! ;)

I could not make something great, especially when limited to 32x32, 3 colors (and blank), and 4 values for each RGB. But I am good at making references, so I will do that.

I think it should be more compact with the thrusters, but I am not sure how to go about that. If anyone wants to make their own changes to this, then please do.

I will give a commentless thumbs up to the first person to say what it is. And double thumbs up to whoever can make it face the CORRECT orientation, I forgot to make that right way. I’m still sad that it is and never will be on iPhone :(

(I tried to include a high definition image as a joke, but that did not work at all)

I love it :) is there any part of it you want animated? The bottom part is now all the same... if noticed how I did the animation, we just need a few copies of the animated parts and i can copy them into the Sprite to create the animation...

was8bit 2019-01-29 06:02

Ok, so after a burst of inspiration, I did a clever trick to get 4 colors (could have had 6) in the Sprite,, the trick is I overlaid 2 sprites over top each other... remember that color 0 is actually "clear" so clever placement of pixels and now 6 colors are available, albeit between 2 pictures overlaid on top each other..

Also, I removed the animation and made one color responsize to acceleration ... the boosters powering up to move the ship..

Whatcha think ??? If you like it and or are inspired, feel free to redit what i have done..

The Sprite on the left of the memory uses palette set 3 and the Sprite in the right of the memory uses palette set 4... careful changes to both and then careful editing of the two sprites can result in one Sprite with 6 colors, but careful thought to how the "clear" color #0 will allow the overlaid colors to combine have to be considered ....

was8bit 2019-01-29 06:39

Ok, got creative and chopped up the Sprite into 3 parts... the center top part now has "scanner" lights animation as well, in yellow.. spaceship now has 5 colors :)

Does anybody know what the starship is from and is called? It will help if you look at the colors I used. I will edit this on Friday (unless I forget) with the answer.

Not a clue, sorry...
