A8 Shoot'em'Ups all:

[José Pereira]

Cannot explain right now, but try to guess how I came into this and "what's up Duck?"

O.k. let's see if I can explain.

 

I lost (win) all the weekend with this...

 

 

I saw TMR's Blog and his difficulty to get Sprites on an A8 Shoot'em Up.

Before was that Probe technic used on that SuperMario and Contra...

 

How would it be possible to get more?

We have Ripper but flickers...

 

 

All the Screen Gfxs. are Antic4 CharMode in 5colours with possible DLIs.

From what I've tested in some Ground stages, the total number of Chars are between 100 and 112.

This is very good, only 1Kb. for Screen Playing Area and another 1Kb. for the Status Area.

16 or so Chars left for Shoots/Bullets probably no more needed.

 

 

 

I've then thought what could I get if I used Multicolour PMs., missing each Player with a Missile (all 4Missiles expanded to quaduple size):

P0 OR M1

P1 OR M0

P2 OR M3

P3 OR M2

(get third colours, although only 2Ored ones: (P0&1 ORED M1&0) and (P2&P3 ORED M3&M2)

2(Ored)+4(Players)=6colours.

 

 

 

What I've done was some design by Hand/Head using this.

Never even copy any C64 Sprite, just do them like what I have in mind.

 

 

 

The majour idea is to have:

2PMs.: (Our Ship & Weapon Add-on) or (2Ships) in a two Player Mode.

2PMs.: 2Enemys by Line.

 

 

 

Now comes the real tricks:

First- Get good IMHO Ored Colour combinations.

 

Second- Get good IMHO with quadruple size Missiles (I'm trying...)

 

Third- Our Ship seems a little bit Horizontally short, so, next try will be, probably a double Width Player with the quadruple Missile starting the two (Player and Missile) at different x coordenate, will get a Sprite wit 9,10,11 or even 12pixels wide.

 

Fourth- Still need more than two Enemys by Line, but two is better one.

2+2+2 Enemys at the Top, 3 different Lines than some flicker, but it's the way the Attack waves design that would get good or bad, little or great flicker.

You can also have different Waves at different parts of the Screen.

(something like this:

P2-Red P3-Green at the same Line

P2-Yellow P3-Brown at the same line

The Top two never crosses the bottom two.

 

 

 

 

There's a very good thing, and this is that now you're only working with PMs. and 2Kb. (Playing+Status Screen Areas),

and you'll get free Time/Speed to get more PMs. on Screen.

Just Soft Sprites for Bullets (probably they are just Char by Char replacements...).

 

 

 

 

Yeah, the real trick are more the colours, because the shapes I think I can getb something...

We can have an alike Armalyte (A8RMALYTE, can you read this word? )

Sounds interesting to combine p plus m x 4
