This thread should be splitted to a new one. I think from post #113.

DamienD · 03 September 2019, 13:32

Yup, will do this but need to think what to call the new thread and where to move.

Edit: done, all post here moved from this thread: Metro Siege: new arcade quality a500 brawler!

Nicely done DamienD, sorry to go off topic

Interesting reading all the tips, tools and techniques, hope to share more info with video tuts once I setup the capture card.

I always thought it was impossible to reload copperlists "during game", at least to change the Y position of the color-change.

I was really surprised when I begun learning Blitz Basic that *it is* possible. I even wrote a routine that "simulates" vertical scrolling by just changing the color of a single palette entry on different scanlines at each frame.

I don't think commercial games did this too much back at the day. It was either the famous "Rainbow" effect, or games just didn't have vertical scrolling when using it (Like Shadow of the Beast... the levels with vertical scroll didn't have so many colors on screen... or Jim Power).

Lionheart did it dynamically in those dual playfield levels..

Yep, it's probably one of the most complex copper lists of all Amiga games... color gradients in foreground + background + perspective scroll, and everything scrolls horizontally and vertically, and even the swamp perspective changes (stretches) when moving up and down. Total masterpiece (even if the cloud scrolling is wrong when you run

).

Apart from that, also Kid Chaos changes at least background colors, and Apano Sin is a vertical scroller that changes palette quite a lot.

Nothing......

If I remember correctly from the Codetapper interview, SWIV also changes copper colours dynamically, transitioning betweens different palettes of areas on the fly.

Nice technique.

Shatterhand · 03 September 2019, 19:05

Oh yeah, it's true. Swiv does it very smartly indeed.

I don't remember exactly what it was now, but in Lionheart the effect was really ... weird to me, as platforms actually changed color as they moved. It never felt right IMO.

I never tried animated GIF with Photoshop but with Gimp you can have an indexed colours image + layers. Each and every layers are then combined to animate the GIF.

Dunno if this can be considered in-topic, anyway I found this stuff useful in Photoshop:

ProMotionNG looks cool, gonna check it ASAP!

XNView loads and saves IIFs, and from memory it can read (but not save) HAM images. It's got a pretty decent palette reducer built in (I also use PSP, but I'm not terribly fond of it's color reduction tools so I tend to use either XNView or something else if needed).

My problem with this feature in Gimp is, that the preview area cannot be enlarged.
Watching a 32x32 animation on a 1280x900 display is challenging, to say at least...

Time to post an RFC then
