EDIT: Oops, yes, it is the same as rubystein. Think that technique might be a bit slow in Ruby though, since you have to read and set pixels, not just draw whole lines (went down from 50 to 3 FPS when I just drew the lines pixel by pixel rather than using a line primative...so not a possibility!).]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6880 Spooner 2013-06-17T11:48:29Z 2013-06-17T11:48:29Z 5
I'm really impressed that Texplay worked so fast. I still get 45FPS when I run it at the full 640x480.

If you use:

    moveSpeed = 10.0 / fps
    rotSpeed = 5.0 / fps

Then the movement speed is no longer dependent on actual FPS.

I'd also recommend using #div and #fdiv rather than forcing to_f and to_i before division with /]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6878 jlnr 2013-06-16T21:50:25Z 2013-06-16T21:50:25Z 5

jCaster - "j" as in "jahmaican", not as in "java" obviously!

So I was bored and I was reading about raycasting here and I decided to rewrite this in Ruby. There's still room for improvement, but it works as is.
I used Texplay as it's the simplest solution, but consider it temporary cause it's kind of slow.

Added strafing and made the sky blue so let's call it 0.02 :)

Arrow keys/WSAD - movement

#set & #show are a bit convoluted. Try:
attr_accessor :speed, :gravity, :x, :y

def pos; [@x, @y]; end
def pos=(value); @x, @y = value; end


Then you can do @gracz.pos = [5, 100] or @gracz.x = 5 or puts @gracz.gravity to manipulate the instance variables in a more friendly manner.

Although I said to use spaces instead of tabs, please don't mix them, because that is the worst of both worlds ;) Your editor should be able to automatically replace tabs with 2 spaces.

You might also consider putting your code up on somewhere like github.com, which makes it easier for people to get hold of (no real need to release Windows version on a site like this, since everyone here is a Gosu developer and they don't really need an executable).

Good luck with the project and I am looking forward to being able to interact with the terrain in the game!]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6835 Spooner 2013-05-17T08:54:12Z 2013-05-17T08:54:12Z 12 http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6828 SeamusFD 2013-05-16T19:56:49Z 2013-05-16T19:56:49Z 12

I'd recommend you look at a higher level Gosu framework, such as Gamebox or Chingu, to make things easier for you once you add more functionality.

A few comments on the code, to help you along with Ruby in general:

Rather than using if/then/end on one line, we generally use the single conditional postfix this way:
close if button_down? KbEscape

Use two spaces rather than hard tab. Makes your code look a lot nicer when viewed online too.

if @obrot == :prawo then
We don't usually use then; It just isn't necessary. Also, that bit is crying out to be a case statement.

Rather than use your own #debug method, use Logger (standard library) or Log4r (gem) for logging.

for i in 0..2 do => (0..2).each do |i| (Although for might feel better if you are coming from another language, it is extremely limiting once you try to do a bit more with Ruby)

def block?(x,y); @map_main[(y/32)][(x/32)] != 0; end

Use ?: over if/then/else/end on one line (or put it on multiple lines).

print(Time.now.strftime("%H:%M:%S.%L") + " - " + message.to_s + "\n") => puts "#{Time.now.strftime("%H:%M:%S.%L")} - #{message}" (although I suggested using a logger for this).]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6815 jahmaican 2013-05-16T10:38:49Z 2013-05-16T10:38:49Z 12 http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6812 ExplodingCookie 2013-05-15T22:52:17Z 2013-05-15T22:52:17Z 12 http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6811 jahmaican 2013-05-15T20:18:27Z 2013-06-16T16:20:25Z 12 http://i.imgur.com/EAyQ0SUs.png] [http://i.imgur.com/Ck6QI2ts.png] [http://i.imgur.com/3dITIeKs.png]
Hi! I'm relatively new to Gosu and Ruby in general, but still wanted to show my first creation.

What's new?
Added jumping (finally!).
I'll probably rewrite the whole thing for Chingu some time soon.

What is it?
Intended to be a 2D Minecraft clone. Still needs a lot of effort.

What's done?
Drawing a 3-layer map, basic movement, very simple physics, basic building.

What has to be done?
Improving movement.
Introducing bigger maps with scrolling; storing them in more friendly format maybe.
Creative mode just like in real Minecraft + flat map generation.
GUIs, menus etc.
Actually learning how to Ruby.
Then maybe some proper mining and crafting.

How do I play?
Left/A, right/D - move left/right.
Up/W -jump.
Left click, right click - destroy/place blocks.
1, 2, 3 - choose material.
Middle click - teleport.
Escape - exit.

What was used?
Tiled editor - the map you see can be easily edited.
Coterie Craft Minecraft texture pack.
My Minecraft skin.

I think the way to fix this in the long term would be not to use OpenGL for collisions, but I don't know a good replacement in Ruby either.]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6788 lol_o2 2013-04-25T19:18:13Z 2013-04-25T19:18:13Z 118 I just played BM on that laptop. No lags.
I couldn't believe so I played that game, which had 5 FP before and... NO STUPID LAGS!
The only issue is that images are loading 1-2 seconds, but problem vanished. Just vanished.
This dragonheart can't run Bottomless Mine (which I run on my second computer seamlessly). He has the same system and graphic card (different model) as me.
Just no comments -_-']]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6787 lol_o2 2013-04-23T13:24:45Z 2013-04-23T13:24:45Z 118
  def modify_mask(mask,method)
    @mask[mask].render{
      if method[0].class==Image
        method[0].draw(method[1],method[2],0)
      else
        $screen.draw_quad(method[0],method[1],c=method[4],method[2],method[1],c,method[2],method[3],c,method[0],method[3],c,0)
      end}
  end

To explain it better:  @mask  is hash for Ashton::WindowBuffers (so probably OpenGL Textures, right?) and every object (tile,door...) by calling this method, draws an Image or quad onto Texture.
I know it's not too efficient (new render block each time), but I ported Ashton after the game was completed so I had to replace  'splice'  and  'rect'  quickly.
And collisions come by just reading pixels for proper mask (so it's color = @masks[mask][x,y] and then true if color==Color::BLACK etc.)

And this ~5 FPS is rather OpenGL issue, because on this laptop even old RTS Tzar tends to lag. Maybe it's because of ATI gfx card?]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6786 lol_o2 2013-04-23T13:07:24Z 2013-04-23T13:31:03Z 118

Re 5 FPS: Do other OpenGL games work fine? This sounds like a Gosu or Ashton bug! Feel free to open a new topic / thread for this.

I know what you mean though, now that every Ludum Dare has ~1000 entries, it feels like there are more players than games. I wish Gosu would work on the Mac App Store or Ouya or something like that :/ And sadly enough, OpenGL & OpenAL still cause driver issues in 2013.]]> http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?pid=6784 RunnerPack 2013-04-23T01:03:55Z 2013-04-23T01:03:55Z 118

I'm building iOS apps all day nowadays, and they're all chock-full of analytics to report errors, checkpoints etc., I guess Gosu games should do the same :) Or at least they might have a "bug" button that emails everything to the dev as a YAML file...
