Big Blue

[cNp]

Hi all,

I'm starting this thread to track my progress in learning to program the Vectrex.

Really basic stuff so far so don't get excited but I think posting updates will help keep me motivated.

Big Blue is the game my son thought up for me to do and the one I'm using to learn 6809 assembler and the Vectrex BIOS routines. At the same time I'm starting on the game I would like to release a physical version of somewhere down the line... ... ...

So far I've read Manu, Chris Tumber, and Chris Saloman's tutorials and code and have:

Got a diver on screen (graphics are first attempt with co-ords worked out in my head)
Got a diver moving
Added a fish
Made the fish move in relation to the diver
Made the diver face left or right depending which way he is moving
And that's it!





To do next:
Add collision detection with the fish
Make fish move independent of the diver
Make fish avoid the diver
Animate Diver
Add shark
Make shark track the diver
Add collision detection with the shark

Thats great, bro!
Please start a video documentation as well :-)

Nice idea! Especially since there aren't many water-themed games for the Vectrex. (Hence why the Berzerk overlay works well!)

Very cool!

Bubbles following the diver or making the legs kick would be cool. Nice start.

Going to be animating the diver so will include some bubbles, nice idea!

Getting strangeness from my collision detection (trying to print some text makes the screen go blank and tryig to play some sound plays no sound) but it definitely is detecting collision... .. ...

Nice to see some first results, Chris! :-)

Been doing a bit more code today:



The collision detection using Obj_Hit is a bit rough... need to mess with that a bit more.

Score code is nicked from Manu, just using it to let me know when collision is detected (or not).

Once again the shark was drawn on paper and the co-ords done in my head... just needed a little tweaking to make it all join up at the end.

(Insert Jaws theme here)

:-D

Certainly on the cards! Not done any sound at all yet... thought could start the "durrr duh" a couple of seconds before the shark rocks up!

Exactly :-)

Looks great!!!
I love sharks :-)

[gliptitude]

Neat!

That shark sprite is really slick. Very nice design on that one.

[TrekMD]

That shark sprite really does look awesome! But it does need this...

[cNp]

Ok, ok, ok... it's gonna get a Jaws theme :-D

Not sure my musical abilities even stretch to working out the 'durrrr duh' 'tune' but I'll get there one way or another!
