Hydra challenge, new NotEye, HyperRogue music and exploits

It seems that a lot of things have happened during the last month...

In the previous two weeks, Hydra Slayer was featured in the Reddit Roguelike Weekly Challenge. Players were asked to play Hydra Slayer and reach as deep as possible. You can see the results here.

I had some fun, and I hope that the challengers had fun too. Congratulations to ionfrigate for winning! :)

Still, I think that the Hydra Slayer challenge did not show the game's full potential... I mean, it was not as fun for the players and myself as it could be. For players competing for scores, I think it would be better to count the wounds gained during the 50 levels, instead of going as deep as possible (I think that the game gets quite boring after level 50...). Also, all of the high-ranked players have been playing as daughters of Echidna, which is unfortunate IMO, as they are the least interesting race for me: it is easier to construct an efficient weapon set for Echidna than for other races; using this efficient weapon sets is a rather boring calculation; and they seem to be more powerful than the other races. They pose an unique challenge due to being completely different than other races, but if I was organizing a competition, I would probably ban them.

Still, weapon sets that have been used by different players have been a bit different (one of them used a pick axe, which was surprising for me).

The challenge led to some improvements in Hydra Slayer!
Hydra Slayer 15.2 features:
  • The potion of knowledge is now usable only against a single enemy. This is actually more logical: when facing a bloody hydra and a vulture hydra, for example, you can choose whether to unblood the bloody hydra, or to analyze the vulture hydra.
  • Also, the potion of knowledge is now less useful on shadow hydras: it now shows three single handed attacks. Before this change shadow hydras were extremely boring for Echidnas, since for any respectable Echidna three attacks are enough to kill a shadow hydra, and thus shadow hydras boiled down to drinking the potion and noting the numbers. Especially boring when there were lots of other Hydras in sight, and the game had to analyze each of them, which takes a lot of time for ambidextrous slayers...
  • To nerf the Echidnas a bit, they are now slower to use items. Using items costs a turn, and throwing powder at hydras costs another turn (and the hydra attacks in the meantime while the powder is thrown!). I think that Echidnas need more nerfing, though, so please comment if you have any ideas for this.
  • Some bugfixes: shadow hydras are no longer detected with a right-click. Keys such as 'm' and 'f' now actually work when a hydra is stunned (previously, the screen tended to disappear right away in this case... this bug appeared in UberHunter's videos and I could not find the reason for it, but it was apparently caused by the stun animation). The semi-transparent part of the screen sometimes appeared in the wrong place, this is fixed.


Also, NotEye got some improvements. Some players know these improvements from the closed prerelease of ADOM, or from the Roguelike Bundle draft. Both of these were called NotEye 7.1 (I think), so the official release gets number NotEye 7.2.
The changes are following:
  • Minimap has modes: it can show the old typical minimap from colored boxes, but it can also show the original ASCII screen, or a graphical screen (in the Tile, Isometric, or FPP mode). So the player could play in ASCII mode and have a tiny FPP view in the corner, for example. Also the minimap is movable now, and the default placement is (supposedly) more intelligent.
  • The Noteye window is resizable.
  • A new 3x5 font added (especially useful for the ASCII minimap).
  • Some keys caused NotEye menu to crash in some situations, this has been fixed.
  • Added ChessRogue, Gruesome, Toby the Trapper, and Unstoppable to the NotEye menu.
  • Music now stops when NotEye loses focus. Also better handling of mouse out of the window.
  • Noteye looks for batch files in the 'batch' subdirectory, and can run games via these batch files.
  • Scrollable map. Holding the mouse close to the edge of the map area will cause the map to scroll. Look at the menu (NotEye menu, or some game menu) to center back on the PC. This also means that when the PC is on the edge of the map, the tiles mode will detect this and move the PC off the center, so that more of the map is visible.
  • Zoomable map. You can now zoom the map in the menu (by changing the tile size in the graphical mode submenu), or using Ctrl+Mousewheel.
  • You can now specify the max frame rate, to conserve the CPU.
  • Table streaming, to be used in integrated games, so that special events sent by ADOM will be streamed when creating a NotEye recording or playing via a NotEye server. The next prerelease of ADOM will display a nice, detailed animation when using the machines in the level with lots of guards and a huge shop! ;) (I was surprised when I saw that place first, so no details, go play ADOM yourself if you do not know what I mean)
  • For some games it is good to restrict the map to the original map area, this is better supported now.
  • An option to reserve space below the map appears in the menu now.
  • Fixed some minor bugs with the cache used for zoomed images.
  • Fixed some problems with FPP.
  • noteye_getevent() now actually returns the event.
  • "isosizes" now returns all the original parameters, too
  • NotEye scripts have access to "getkeystate" (e.g. check if Ctrl is checked) and "getticks" (for timing)
You can download Hydra Slayer 15.2 and NotEye 7.2 here.

Last but not least, I am collaborating with NeonCorridor: he is creating great music for HyperRogue. The songs which are ready are available here; comments are welcome :) For a long time, I felt that HyperRogue was complete except that music was missing, and this is going to be fixed in a few weeks. Also, Adam Borowski has discovered some exploitful strategies in HyperRogue, which allowed one to achieve unlimited scores while remaining safe (or practically safe). These are also going to be fixed in HyperRogue 4.0. Stay tuned!

HyperRogue 3.8, and some plans

HyperRogue 3.8 is released!

It has the following minor updates:
  • the window is resizable, instead of having a fixed list of resolutions
  • exits cleanly in case of errors, such as the missing font file or unability to initialize SDL
  • fixed a crash bug with wandering worms
  • mousing over "help" in the config menu lists the hidden features, such as the graphics editor or the showoff mode
  • some command line options are added (try --help)
  • the SDL.dll file has been updated to a more recent version (screen size is now detected correctly)
Thanks to chrysn for creating a Debian package, and reporting the crash bugs!

Download HyperRogue 3.8 here. You can also see its website.

In other news, we are also currently working on the Roguelike Bundle. For now, you can download my preliminary draft which includes a NotEye-based launcher (a newer version of NotEye than the current official release), some roguelikes preconfigured to work with NotEye (DoomRL, Brogue, Hydra Slayer, NLarn, Drakefire Chasm, ChessRogue, Frozen Depths, Gruesome, Toby the Trapper, Unstoppable), as well as HyperRogue 3.8. You are welcome to discuss the bundle. Hopefully we will create something great!

Have fun!

ADOM: graphical prerelease

I think I should mention this on my blog: the first graphical version of ADOM, using
NotEye as the graphical display engine, is available as a closed release!
 

 
This is available for people who donated in the campaign. If you have not donated, it is also possible to buy access.

Have fun!

NotEye 7.0 + Hydra Slayer 15.0

After a relatively long time, a new version of NotEye and Hydra Slayer is released!
This version includes many features and fixes many bugs reported in the meantime.

NotEye 7.0:
  • A selection of palettes. Several palettes are included, and you can even define your own palette. Also palettes with non-black color 0 work somewhat.
  • The choice of font/resolution has been improved. Any font can be scaled now (both up and down). You can also request a specific resolution (e.g. 800x500) and the currently selected font will be scaled to match the requested resolution as well as possible. Fonts which were simply scaled versions of other fonts have been therefore removed, and replaced with two new fonts. (In the future NotEye probably should also support TrueType fonts, or some other format...)
  • You can now save the configuration from NotEye, and have it automatically loaded the next time you run NotEye (when saved before selecting the game), or the next time you play the specific game (when saved during the game).
  • Alpha-aliased fonts did not look well on non-black backgrounds, this has been fixed (again?)
  • letters in mini-tile mode look better now
  • fixed some bugs about the map location
  • the mysterious "view using a selected config" moved to the Network menu where it belongs
  • a new recoloring algorithm (which will be supposedly used for karmic dragons in ADOM)
  • When the game hides/resizes the cursor, NotEye handles it correctly (also added to noteye-curses.h)
  • Renamed keymaps and keytabs (might introduce backward incompatibility)
  • tested on a Raspberry Pi (works, although slowly)
Hydra Slayer 15.0:
  • Giants are sometimes 50-headed and named Hecatoncheires, to reinforce the Greek mythology theme (as suggested in that thread)
  • A rare error with connectivity has been fixed. If you had to abandon your game from the previous version due to being unable to find the stairs, load the savegame in this version, it will fix it for you. (Also this does not ruin the Tutorial, as the previously released small bugfix did)
  • A new rare weapon family, probably not very useful, but always something new (based on the Roguetemple thread)
  • Meteorite Eradicator now uses the correct image in NotEye. Also Eradicator now uses the appropriate ASCII character if the font includes it (works in NotEye's VGA and Fantasy fonts, I have not tried to make it work in Unicode terminals)
  • Weapon materials have been fixed in the Tutorial (in the weapons room).
  • fixed a bug with the NotEye script which caused crashes in some circumstances (I don't remember the details)
A new version of Hydra Slayer for Android has also been released at Google Play (the last version of Hydra Slayer for Android released was 14.0...).

NotEye 6.7 + Hydra Slayer 14.7: First Person Hex

Hydra Slayer in the Hex First Person Perspective
Yet another small update to both NotEye and Hydra Slayer.

The following things have been improved in NotEye 6.7:
  • When you choose the viewing mode before starting a game, it will be used each time. This is useful for roguelikes where you have to restart after each character. Also the config file is more versatile now regarding this.
  • Fixed a bug with the built-in terminal emulator (this bug caused messages to overlap while playing Crawl on Linux)
  • Freeformparams now have additional parameter, "side" (should we also display it when looking at it from the back? usually we do not want this, as these are the back sides of the walls etc., but sometimes we do) and "shiftdown" (should we shift the images to put the bottommost pixel of the image on the ground?)
  • FPP parameters now allow more control. Use (dx, dy, dz) to move the eye position slightly (I have moved it to the front, which sometimes allow us to see more). Use (objpush, monpush) to tell how much the objects and the monsters should be shifted. Use (xz, yz) for non-square grids.
As for Hydra Slayer 14.7:
  • Ambidextrous attacks now check for collapse (thanks to CCC for reporting this)
  • Hex no longer uses the far left/right columns (that was ugly)
  • The Brownian level generator did not work in the Hex mode
  • Some wrapping levels did not display correctly in the Hex mode
  • First-person perspective in the Hex mode (yes, non-square grids are useful!)

NotEye 6.6 + Hydra Slayer 14.6

Hello! Time for some bugfixes...

Thanks to CCC, the following things have been fixed in Hydra Slayer 14.6:
  • Fixed the Primeslayer (did not work without enchantment, although it should).
  • Fixed the ambidextrous Vorpal Blade (did not grow correctly).
  • Fixed the missing end-of-lines in the player log file.
Game Hunter has created a Frozen Depths+NotEye video, which caused the following bugfixes:
  • Cursor shown in Frozen Depths (and possibly other roguelikes in the future).
  • Frozen Depths will no longer interpret the "@" on the Help Screen as PC (unfortunately, I see no way to tell Sages from the PC...)
Also the following things have been improved in NotEye 6.6:
  • The Dungeon Crawl config has been fixed (should no longer detect the PC on the X-map, or interpret other humans are PCs - NotEye now knows that PC is always at the same coordinates).
  • In Linux, NotEye (caller.sh, actually) will now automatically turn off the UTF-8 encoding (and use ISO-8859-1). (This bug caused lava and other weird terrain to be displayed as several characters in Crawl.)
  • Letters now look better when drawn on a non-black background (especially when the letters are black).
  • As suggested for PRIME, mousewheeling upwards now moves your character in the opposite direction.
  • Keyboard input menu is improved. Now, it allows you to turn on/off rotation/translation for numpad and arrowkeys, has more explnatory text, and more options for letter-based layouts.
  • Fixed a bug which caused alpha-blended images to be scaled incorrectly.
  • Fixed a problem with noteye_halt and enabling key-repeat on reload.
  • The 'distill' function is now available to script writers ('getdistill'). Mostly for debugging.
  • Tile debugging ('tiledebug') now provides a slightly more informative output (for images and transforms).
Download NotEye 6.6 + Hydra Slayer 14.6

The Seven Day Roguelike Challenge 2013 will be running from March 9th to March 17th. I have no good ideas for my entry yet, but you are invited to use NotEye as your display engine :) See sample.cpp and sample.noe for a simple example. Have fun slaying Hydras, developing and playing roguelikes!

NotEye 6.5 + Hydra Slayer 14.5

Game Hunter has made several more videos about Hydra Slayer and NotEye. Go watch them!



Of course, some bugs and feature requests were discovered on the way...

Necklace of the Eye 6.5:
  • Some fixes from 6.4 did not actually make it to the release (which actually made NotEye 6.4 unusable with DoomRL and some other games)
  • NotEye now explains what is OpenGL good and bad for
And, on the more technical side:
  • File generic.noe is no longer such a chaotic file, with functions related to many different features of NotEye (view modes, sounds, reading the map, running the game, keyboard input, and fonts). It has been split into several files . Also some stuff has been rearranged.
  • Added some comments in the common/*.noe files.
  • Some sound-related functions added (playsoundloop, playmusicloop, mixsetdistance, mixsetpanning, mixunregisteralleffects) (not yet used, but requested for ADOM)
  • Added 'getobjectinfo' to get info about an object, as a Lua table (for example, using getobjectinfo on a simple image tile will currently return all the values used to create the tile (image, origin, size, transparency key) and the number of empty rows at the bottom)
Hydra Slayer 14.5 (thanks again to Game Hunter for his videos, and Ben Franzluebbers for reporting several bugs):
  • Fixed a bug which sometimes caused hangups on entering the new level in the 4-directional mode
  • invisible walls now look like dark walls, and unknown cells are simply black now
  • shadow hydras are now remembered after you save the game
  • pick axes have been upgraded slightly: they are now doublers (like bows and spears), not stunners, are more powerful (e.g. they work instantly at size 5), have new names and growth messages
  • Mushroom staff now remembers mushroom displacement stats (and is displayed in the weapon history if used only for that)
  • Titans now can press Shift+G to quickly move weapons from the ground to their extended inventory
  • Potion of Knowledge now displays the weapon '0' correctly
  • Fixed a bug which sometimes caused crashes when using knowledge/growth on vampires
  • Updated the onsite feature list to the new theme
