The GMG Cup!

Sure. I've never attempted a 3D game, but I reckon it's fairly straightforward. Read the grid map variable every time the player moves and assign the appropriate sprite to the corresponding object?

I'll try to code a bit tonight.

[Connors]

A 3D game? This will be very cool if it works out, good luck Silverwind!

ALSO I'm thinking about doing a point-and click game, perhaps escaping a dungeon type area, not necessarily called Dungeon Escape but it would be like that project. I decided to finish the point-and-click engine since I'm having so much trouble with my arcade game (All I figured out was adding mouse control was very difficult and arrows were not supported) .

Oh... I thought you were going to try to write a raycaster. Does GM have pixel or line drawing commands? If so it's possible.

There are no drawing commands in GM like there are in SC.  A 3D game would have to be done hand-drawn (like I did with The Maze II) or with sprites (like Tireas Dragon did with Labyrinth).  Sprites wouldn't be too hard but if I remember correctly, Labyrinth was a pretty laggy game.

Nope. I'm using a sprite based display similar to that of Labyrinth, as Charlo pointed out.

Sprites wouldn't be too hard but if I remember correctly, Labyrinth was a pretty laggy game.

Your memory fails you; it was a horribly laggy game! Mine will be several times worse though, as I want to display 15 tiles simultaneously, whereas Labyrinth only used 12 (I think).

I just feel like a challenge and trying something new. The hard part will be condensing the code.

45 minutes and a cup of tea later, here's a pic generated straight from GM:



Using this grid map:

Code: [Select]

001
100
001
100
001

The only trouble I've come across so far is having to write a different value extraction routine for each direction the player might be facing, but I remember TD having problems with that too (and he actually resorted to using four map variables). Hopefully I'll get to finish the engine off tomorrow, and then I can make a start on the floor/wall textures.

[Tireas Dragon]

I don't remember having to use four map variables for labyrinth. I remember having a variable for every wall though and a bunch of other things. In the end I had a nice game, albeit very laggy, but nice.

Cool.  I suggest making a game with that exact graphic style and color scheme, it would be pretty surreal.

Maybe it seems easy because I haven't tried it, but to account for the player facing a different direction, couldn't you just write an algorithm to twist the entire map variable?  

On second thought, that doesn't seem easy at all. :/

[Tireas Dragon]

Well lets see maybe you could twist the entire map variable.
Seems to me it wouldn't be too hard

Assuming your grid is 7*7

newgrid$ = ""
y = 8
x = 1
temp = 0
REPEAT 49
  y = y - 1
  IF y = 0 THEN
    y = 7
    x = x + 1
  END IF
  temp = x * 7
  temp = x - 7
  temp = temp + y
  temp$ = MID$ oldgrid$ temp 1
  newgrid$ = newgrid$ + temp$
END REPEAT

That might work I haven't tested it and I haven't used GM in a long time. If it does work it would change
0110120
0101001
1010010
1001011  
1001010

into
1111100
1000011
1000101
1111010
1000001
1111102
1001010
well that rotates 90 degrees clockwise.

Finito! http://www.mediafire.com/?1lgb10pjay4a14c

It works perfectly with hardly any lag, although it might become more noticeable with larger graphic files. I wonder why it runs so much faster than Labyrinth? I've included the source for all to use. I can't wait to make a simple game with this!

EDIT:

Here's a map of the test dungeon:



You start in the top left corner.

Oh, I must be mistaken. I thought you had used one for each direction.

Yeah, Labyrinth is one of the greatest feats ever accomplished in GM!

[WarHampster]

Nice! I expect to see an old-school dungeon crawler for the contest  

BTW I think I've played Labyrinth but I don't really remember. Where can I download it?

[Silverwind]

There's a link in the game downloads section. I can't get past the fiendish second dungeon!

[Tireas Dragon]

Are you referring to the fight with the first monster? I didn't think he was that tough.

P.S. Very nice game.

[Silverwind]

Oh, maybe it's the third dungeon I'm thinking of. The one with all the spinners.
