Hello, all. Jetrel and I were talking a few days ago, and... long story short, I've made a demo!
![]() Mac Build: OPP-0.2.0.app_7_30_13.zip Windows Build: anura-opp-0.2.0-20130713-win32.zip (Requires vcredist to run.) Changelog ![]() We're doing this in Anura, which was the engine we developed to run Frogatto. We should probably explain a bit about it; I apologize for this sounding a tad like a marketing pitch: Anura's a fairly modern engine with full hardware acceleration. It runs on darned near everything (almost any computers or mobiles), and we've now had at least 6 fully-functional games written in it (at least 2 of which are completely finished). The important thing is how flexible it is; some of these games are radically different genres - Cube Trains is an iso-3d block-based building game; Frogatto is a side-scrolling platformer. Both of these worked with no code changes to the engine - all you have to do is edit script files, and you can make a completely different game. A big thing which matters here is that the engine has a bunch of pixel-art specific features in it; we wanted to be able to do a lot of the typical pixel-art tricks you're familiar with from classic games (and emulator features like HQ2x); many of them are implemented in a radically different way, but overall they "emulate" the feel of many scanline effects from classic 16-bit games (parallax, distortion, palette-changes, etc). I've only added a few things to the game so far, but I've collected the images I could find in the forums and the wiki. I'm sure I've missed stuff or got an old version of something, but if you let me know we'll get it in ASAP! ![]() On to the technical dirt. If you've downloaded the release from above, you'll find all the images in ~/modules/open_pixel_platformer/images. (Where "~" means "wherever you installed the program".) I haven't organized them very well, so if someone would care to have an organize at them that'd be great! (If you move images around, it would be nice if you could update the paths in the .cfg files by searching for the image file name in ~/modules/open_pixel_platformer/data.) Anyway, how do we want to organize the files? Oh, also, I have no idea who the authors for the works of art are atm, so if you could speak up for posterity that would be great. We'll get everything sorted in the end, but this would make it much easier. ![]() Image Format and Specifications: The Anura Engine reads .png images with full alpha channel support. In addition, it has two "magic transparent colours" available, a tan (#6f6d51) for backgrounds and a red (#f9303d) for outlining frames. If you make any pixel exactly one of those colours, it will be treated as completely transparent. We give you the option of either approach; both have their own upsides and downsides, and we ourselves use both in different parts of Frogatto There aren't many limits on sprite size; spritesheet images must be an even number of pixels wide, and be less than 1024px². The size of an individual sprite inside such an image, has almost no limits - they absolutely do not need to be a power of two (eg, 64px², 256px², etc). Spritesheets have a lot of flexibility for organization; individual animations can be laid out horizontally, or vertically, running forwards or backwards (or both). Animations that are too long to fit in one row can even wrap, like words in a book (though they must have rows of equal length). Animations must have all frames be the same size, and the same duration; we can chain animations together (i.e. starting a second animation whenever a first one is finished), and this takes care of all cases where we've needed an unusual frame duration, or needed some frames to be bigger than normal. We have a simple key-point system to make sure animations of differing size line up correctly when switching between them. If you open the built-in editor with ctrl-e, images will live-reload when you save the file in your editor. This makes it much quicker to see if the animation is "working". ![]() Tiles should be 32x32 pixels across, and the total sheet size should probably not exceed 1024 pixels. It won't run on the iPhone if it is too big. Code format and specifications: It's all text files. It's all scriptable. The entire game is completely customizable with nothing but notepad. And it'll do this neat "live reloading" thing while you do so, so you don't have to keep exiting and restarting the game to test your scripts. ![]() Anyway, I guess the question is – what do people think of the engine? Should we go ahead and make a game? Edited by DDR - 31 July 2013 at 8:21pm |

Mac build doesn't work for me. Tells something about Frogatto module missing.
I can run it from command line using module parameter: "/Users/Nek/Downloads/OPP.app/Contents/MacOS/Frogatto --module=open_pixel_platformer" |

Hmm. There is a possibility I can run it because I've tried to compile Anuro from sources recently and thus have all the dynlibs installed.

It's http://ddr0.github.com/files/release/mac/OPP-0.0.1.app_7_29_13.tar.gz. I wasn't able to test it, since I don't own a mac. What happened was a small configuration file was missing and the engine tried to load the default module. Sorry. ![]() Originally posted by Hapiel

It works, and it is awesome! :D
Thank you so much! Best of it, the editor is super easy to access and allows everyone to make changes on the go, whether you are going to script or not! I will soon take action (2 weeks) to write all contributing artists personally about our plans to get this into a real game and this project will get back into running!!!

Thanks for the tip DDR but sorry to say that it didn't work.
DEP told me that the application couldn't be added. Running as Administrator and setting compatibility mode went a little further: ..\..\..\anura\src\raster.cpp:251 ASSERT EQ FAILED: glew_status != GLEW_OK: 1=0 I'm on Windows 7 x64 I tried installing the 64 bit 2012 redisit but that gave the dll error again. De-installed the redists and reinstalled the x86 and the level loading started again but again with the BEX message. Too bad that this happens and I hope for you that I'm an isolated case. Can you maybe look into the Mac build where the tar.gz seems to have symbolic links instead of the files required? I don't care which platform works, as long as one does :) Best regards from M.E. |

Holy freakin' excited... The editor is awesome! I know what I'm doing this evening!
ME: I am also running Windows 7 x64 and it runs flawlessly. Do you have IE10 installed? A few months ago MS pushed out an update for it that has caused a lot of issues, including with the stack hash module. Check and see if KB2670838 is installed, and if so, uninstall it. Also remove IE10, it's absolute garbage. Other than that, I'd try updating your video card drivers. Edited by Noburo - 31 July 2013 at 11:43am |

Yeah !!! Finally managed to get it to work.
I installed a virtual machine with Windows 7 x64 and installed the x86 redist and the game ran fine! Unfortunately my baremetal host can't run it even with the tips from Noburo! WOW very impressive editor and from first glance this engine really looks well! Compliments! I definitely will be investigating this further! Best regards from M.E. |

Now working fine here on win7 64bits !
I kinda struggled with those redistribuable files until I decide to use the one you uploaded instead of the official one, after a reboot and granted administrator access plus winxp compatibility (dunno which one was strictly required though). Anyway, big thanks for this tool, really :) |

We are the same people who make the official ones. All these are is beta versions of the next version. The reason we're posting them is that they contain certain things crucial to doing the OPP stuff - they're almost a year newer than the official builds on our site, and we've done colossal engine improvements since then. A few of these were bits of special code we wrote, specifically to support OPP (like allowing 32x32px tiles). |

This implementation has been updated to work with the latest version of the Anura engine. I hope to get a new version out soon after the new art has been collected and organized into spritesheets.

I'll try and finish up that tree tomorrow and then start cleaning up a few things on the tileset. I also plan on redoing the leaf foreground tiles as well. Good to see you're still working on that engine too btw :)

Oh, maybe I'm just being slow... jungle_bottom_grey, jungle_wall_grey, all here. I did discover something new, though... the latest version of my engine is being kind of difficult, and it helps to have all the tiles that should tile on a single image. (Kristas, our engine programmer, said it was really slow to do it any other way, and also called it stupid.) I'll recombine the images, though, since it's kind of my fault.

Hmmm, why is the set also reorganised?
And I guess there must be a way to script that all the mini sets get combined, but stay at the same place? Also, on the collections you made the tree, water, bridge are still missing, or is it okay for those to be on separate images? What exactly needs to be on the same image? Every asset used in the same level? |

short: If a tile is part of a matching set, it needs to go in the same image as the rest of the set now.
long: Let me start from the beginning. I have been unclear. In our level editor, when you draw out tiles they get put on a layer according to their type. We can do stuff with these layers, like make them do parallax scrolling or have a shader applied to them. We can also edit each layer independently of any other layer. It turns out that our engine, when it actually draws the game to screen, draws each layer independently of any other layer. There is a fast, simple case where it can draw one layer from one source image. There is also a slow, complex case where the engine can draw one layer from many source images. As of last month, the engine stopped supporting the slow, complex case. So, to get to OPP: I've got the tiles set up now in a simple auto-tiling system. When you draw tiles you automatically get corner tiles and sides tiles and fill tiles where they ought to be. If you draw a 3x3 square, this means there are nine different tiles that get placed for your one action. (Four corner tiles, four edge tiles, and a center tile.) Each tile that makes up this 3x3 square autotiles with each other tile in the square. However, all the tiles must be on the same layer for this to work. And now to be on the same layer they must be in the same image. I've put all the grey jungle tiles on one image and all the brown jungle tiles on another image, because I don't think they need to autotile with each other. They can still appear in the same level, but grey tiles will always be behind brown tiles. They'll never 'join', so you can't have a 3x3 square with 7 grey jungle tiles and 2 brown jungle tiles. But you can have two 3x3 squares, each one made of brown jungle tiles or out of grey jungle tiles. Tiles that need to autotile together need to be in the same image. That is, if a tile should join with another tile, it should be in the same image as that tile. A different example: Say we've got some grassy background tiles, which go behind jungle ground to give it some depth. Since the grass only needs to tile with itself, it can be on another layer. So, it can be in one image and the jungle ground can be in another. Hope that clears it up, please tell me if anything confusing. I'm a pretty lousy writer. ![]() Edited by DDR - 09 May 2015 at 4:17pm |

Oh, to answer your other questions:
I could make a script to combine the mini sets, but it would just glue the images together with plenty of padding. I was hoping that the big compo I had could replace the mini-sets. I also exploded the tiles farther apart so we could add in more tiles later without having to move stuff around. I haven't done any implementation yet, so we can still move stuff around and decide how we want to organize everything. The tree, water, and bridge are all in sets of their own and will be fine. (The water-column is maybe an edge case, but I'll deal with that later.) |

Yep, I think I understand everything :). Your engine doesn't mind working with a lot of layers? Then I'll keep everything that does not autotile together on separate files.
I'll use the super padded files you made if future tiles pop up. The advantage of a script or something alike would be that I only need to update one set, since I would still like to also package everything tight for other users of the set. But probably there won't be much additions to the jungle set in the near future, and putting a tile in the right spot twice is not that much of an effort, so I guess it will be fine :) Thanks for all the clarification! |

OK. We can rebuild the super-padded sets from the expanded sets, too, if we want. Zealous crop on gimp already gets it down to 448x419, and then it's just a little copy/paste to get it even more compact... but, and I say this from a programmer's point of view, there's really no reason to compact the spritesheets at all. Computers are insanely powerful these days.
