Space Invaders, or maybe GridRunner...

Bamse

Anyone done this yet ?

I've playing with my 6502 system for a while but it's time to get back to the Hydra...
My first game "Mercury Mission" was pretty much just an exercise to get up and running with Spin.

I want to learn how to write my own driver and renderer for NTSC so this time I guess I have to tackle Assembler...

Guess one good start is the "SimpleNTSC_256x192_256_colors_002.spin", it's pretty basic...

[noparse][[/noparse]X] I got the Motor hooked up with the H-bridge and the 555 is supplying the PWM.
[noparse][[/noparse] ] Now, if I can only program the BOE-BOT to interface with he Flux Capacitor.

Hi Bamse, i did a rubbish version of spacies, while getting started with the prop, so be my guest and do a decent version, as it'll save me a job of re-doing it now I know the processor more [noparse]:)[/noparse]

oh and SimpleNTSC_256x192_256_colors_002.spin is a great starting point, but will remove any option of a PAL version. guess I really must have a look at converting that to PAL some time, when my to-do list is small enough lol.

Baggers.

Bamse

Well, Space Invaders is going to be my next project then...

The NTSC_256x192.... was a great help for me to understand how to generate a page.
I still haven't figured out the itty bitty details but I managed to understand the principle...
The calculation on what to put in the VSCL and Waitvid is still a little bit of a mystery to me...
Just need to stop playing Frogger and Unterwelt and get back to the code...

I do agree that it would probably not be a good starting point since it's NTSC only, but it really helped me getting started...

I might just scrap the Space Invader idea for now...
Hope I don't disappoint to many people...

Another game just came into my mind, Jeff Minters GridRunner...
This is one of my favorites and I think it would be much more fun for me to remake this game rather than Space Invaders...
Guess I have to start up the C64 emulator and get some inspiration...

I wrote a clone of that for the Atari 800 when I was going thru my "TRON" light cycle game programming phase, definitely more to do than space invaders.

There is hope, I found the font by doing a memory dump from VICE...

Howdy, been a while...

But the old shed is torn down, the dogs got a new dog run and the gutters are cleaned...
I also found a couple of LCD displays that I had been looking for and finished up a couple of projects for my Replica One, a 6502 system...

So it's time to get back to Gridrunner...
Got the missile to shot and some Centipedes running all over the screen...
I also need to start looking into sound effects, it's pretty boring without sound...

The whole weekend is booked up for a family event so I wont be getting back to Gridrunner until Monday...

Finally, I got rid of that annoying little bug...
Did anyone notice that the centipedes where turning a little bit weird when climbing up ?

I guess this was due to a conversion problem between bytes and longs.
I eliminated the use of -1 in my array of bytes and now it all works...

I just tried this for the first time and it is pretty sweet. I like the intro with loader screen from the C64.

Keep up the good work!

Bamse

Added a bunch of comments, hopefully the code can be understood by others...

You can now crash and the lives are counted down, the scores can be set, they are no longer hard coded...
Time to start working on the actual game logic a little bit...
And maybe even add some sound...

OK, one more thing before I can start working on the logic...
I need to figure out how to split the Centipede...
But that seem to be a task for the weekend...

Looks pretty cool now that the Centipedes actually turns...

By the way, does anyone want to help out with the sound ?

Yes it's pretty hard right now...

I would imagine this would be Level 20 or something...
That will be the weekend project, to start at level 1 and get harder and harder up to this level...

Here are some "screenshots", I will have to convert the driver to allow for that screen capture tool that is available somewhere...
I'll try do this once the game is done...

Excellent game! Hard as heck! [noparse]:)[/noparse]

I've attached a copy that is fixed for Demoboard/Protoboard users.
(If they have a NES controller attached to the same pins as the Hydra)

I've also taken the liberty of adding a dummy sound driver to keep the game from crashing.
(For those who haven't made the investment in the Hydra book/system yet.)

@AndreL: If the dummy version of NS_sound_drv_052_22khz_16bit is an annoyance,
let me know and I'll yank it. It's an empty shell with a good plug for the Hydra Book
in the comments.

Need a part? Got spare electronics? - The Electronics Exchange

Bamse

Thanks guys, I'm glad you like it...

Here is a minor update that will hopefully easy the port to the Demoboard/Protoboard users.
If I got it right, all you need to do is to change the parameters below and recompile, no need to change the code in the Graphic driver...

  ' Set up the processor clock in the standard way for 80MHz on HYDRA
  ' You will want to edit this to reflect your clock setup
  ' Also necessary is editing the pin definitions, and that's done in the driver itself.
  _CLKMODE = xtal1 + pll8x
  _XINFREQ = 10_000_000 + 0000

  SOUND_PIN = 7                 ' Pin used for sound effects, pin 7 on the Hydra
  VCFG_PINGROUP = 3             ' Pingroup for video output, 3 on the Hydra
  VCFG_PINS = %0000_0111<<24    ' The actual pins used to generate the video signal, bit 24 to 26 on the Hydra

Baggers,
I'm going to give you full artistic freedom with the sound effects.
Please feel free to use the included silly little sound engine or write a better one.
Also let me know if you think we are missing any sound effects, these are the ones I have defined so far,

SOUND_LEVEL_START = 129 ' Sound effect for "ENTERING GRID AREA", 1 + 128
SOUND_GRID = 129 ' Sound effect for drawing grid, 1 + 128
SOUND_SWIPE = 130 ' Sound effect for Side Swiper, 2 + 128
SOUND_MISSILE = 131 ' Sound effect for Missile, 3 + 128
SOUND_SHIP_EXPLODE = 132 ' Sound effect for exploding ship, 4 + 128

Thanks for playing...
