Have been fooling around with a game concept for a few weeks now and thought I would share. Named Gridslugger, it loosely plagiarises a little bit of Centipede, a lot of C64 Gridrunner, plus has a few original ideas thrown in....

 

I have got as far as sorting out the character map (used 253 of them!), worked out how the enemies will interact, have all the game rules worked out, and designed most of the screens. I am still putting the finishing touches on the variable list and starting to get a little nervous about memory but think I should be OK.

 

The plan is to start putting it all together over the coming weeks. While not specifically written with the F18A in mind, some of the "prettier" aspects of the graphics will probably suffer from sprite flicker without it - but nothing that should effect game play. I personally don't use real hardware so from my perspective its more about the fun and challenge of writing it rather than making it console perfect. Yes, I am an emulation fan. 

 

I have for years wanted to write a fast paced game but could never wrap my brain around Assembly. In this instance the finished product will be compiled so I am hoping the game moves along at a good speed.

Nice graphics! Is this going to be a Snake variant?

No - Different style of game play. Something like this is more what I envisage;

Ah OK. More Centipedish then. Looks like a ton of fun! Looking forward to seeing your progress :)

Funny, I suggested Gridrunner as a potential port a couple of years ago.

I think Jeff Minter squeezed Gridrunner into the 3.5k on the unexpanded Vic 20. Remember thinking it would make an ideal mini memory game for the Ti-99

I am desperately waiting for a port of Gridrunner/Matrix to the TI ... for more than 30 years. (That is, for a standard system, no F18A.)

Can't really figure out what's actually going on with the horizontal and vertical shooter guys...  And, it'd be nice to have an option to hide the grid.  That makes it really hard for me to see what's going on.

Well.... The only sprites used during game play are for the laser which goes the full height of the game screen (requires 7 vertical sprites), the 5 gunners which run along the outside of the grid, two for the players ship, plus a total of 4 bullets (the bullets won't be in play at same time).  I really don't feel any 4 of these sprites will line up in a row very often to cause any issues.... All other enemies are non-sprites. Only the slug dudes above the grid should be a cause for noticeable spite flickering, and only when they are pooping out an egg before it enters the grid. By removing the mountains I could reduce two sprites and do away with the flickering completely.

 

So while not completely faithful to any original, I think it should be very playable on a standard console without F18.

 

I had never stumbled across that wiki Challenge site. I reckon if I had I would have tried for a more authentic version. Believe it or not I wanted to write something and just couldn't come up with anything original. I started watching Youtube videos and after finding Gridrunner I got a little inspired. I don't *think* I had ever seen Gridrunner before, although I did once own a C64 so who knows what lies in the subconscious....

I think Space Taxi is much like Marc Hull's Mad Marvin's Great Escape.

It looks great, and GridRunner's a great choice. :) Looking forward to the end result!

 

And wishing again we had titles like this back in the day. Damn. ;)

Is this compiled XB256? Or just compiled Extended Basic?

Uses some XB256 features. Mainly the extended character set.

If you're worried about memory definitely use the compresed data statements. I can't stress enough how great that feature is.

I haven't played with this feature yet (but will) - thanks.

 

At the moment I am creating a disk file that contains all the string data for character definition, instruction screens, and some other definitions required in-game. Defining a 256 character set adds challenges that I haven't had to deal with before being an otherwise simple XB guy..... :)
