win build changes, fpc 2.6, CMAKE_PREFIX_PATH, glut header

Link some libraries needed for physfs on windows (there are still 5 symbols which couldn't be found - to be resolved)

Merge

fix deprecation warnings for libav sources

meh

linking phsyfs on osx

allow the engine to use physfs on android too

Merge from 0.9.18

Convert reading hedgehogs limit from map config

Download .zip too, and store them to .hwp

merge... need to remember to update first

Merge physfslayer branch into default. Have fun!

Close this branch

- Download .hwp files into Data folder and mount them immediately (yes, could cause problems in case of overlapped contents) - QuaZIP no more. RIP.

oops

oops

Mount .hwt files found in Data folder

oft-requested, should make the shoppa guys happy, probably, but, knowing them, I'm sure someone will complain

link main on osx

Get rid of DataManager::findFileForRead

Backed out changeset 5d00c28059e3 - enable the feedback button again

cleanup headers, remove -I . from rtl lib to save a few warnings

Use (undocumented) Mix_LoadMUS_RW to load music

mutatis mutandis

some CMake cleanup

We need custom script loading function in lua now

up android target api (but this commit is actually just to test buildbot: desync

fix build

Keeping bruteforce

another tweak tomake --stats-only work on headless servers

and install it too

Oops, didn't realize FindLua.cmake is our own module

Don't rely on hedgehog facing direction, check intentions instead. Should fix excessive turns around and weird jumps to water

comments and runtime list of files to convert and compile

Implement reader in C ffs

Pretend AI knows how to use drill rocket (actually has no idea of drilling)

finally hwengine in c links without errors

Script loading via physfs which doesn't work: - Some scripts just refuse to load for no obvious reason - Some scripts load fine when you set BUFSIZE to a large value, like 64k, but don't load with small values Error messages in both cases don't seem to have relation to lua file contents

Call fallers less often. Should hopefully still be about as effective at the intended purpose. Should help loads quite a bit.

cmake linking for engine in c

Engine loads fine with basic config

make stats-only mode work headless. also skip a few things to save time/memory.

merge xymeng's gsoc engine with a few updates (and further checks on symbol definitions)

Get rid of Pathz and UserPathz

oops

better clang search

- Add physfsrwops library - Load images via physfs (crashes)

Don't accept in-room flags when not in room

merge xymeng pas2c

merge with default

merge with latest default

Some tweaks to AI

fix demo playback

couple of nots

merge

Various tweaks to recent AI change

this wasn't needed IMO

objects too

something bender asked for. allow a mask without a map

oups

search for more clang names

Make FindPlace more flexible on large maps.

no globs, sources not yet generated

merge

correct includes and clang detection

LongInt Land width/height, mouse coords

More strictness on room bans

Fix why my first attempt to compile main had failed, causing me to ask koda what the secret was. apparently using an OS that ignores case...

strip BOM

add a few cmakefiles for c engine and rtl

Only a handful of ISO 639-3 languages are supported by Qt. Standard Malay is not one of them. Using the macrolanguage code seems fine. Not too sure what the numerusform is for a macrolanguage, but appears that wikipedia equates MS w/ "bahasa" too

add FindGLEW.cmake module

Try to beat AI in Mutant!

rename BUILD_ENGINE_LIBRARY to LIBENGINE option, so that no _ are used for cmake options

merge

split WEBGL and NOPASCAL cmake options

add gstMoving to avoid sticking

better GL.h (which was needed after all)

Don't zero TeamHealth, only show empty health bar

add xymeng's pas2c header

Spam log with checksums

empty or old files

Maybe this caused server crashes? Add more strictness on team owner record field

well this was silly

This should ensure zsm doesn't screw up locale, hopefully.

add xymeng's rtl port

Add zsm since Myystery is offering to do this language. Also update the .pro file and existing strings.

move stuff out of engine folder

Remove duplicate files from voices (add a fallback check in uSound). Add JustYouWait as an alternate to IllGetYou. Note that IllGetYou being called every turn seems awkward. IMO they probably should be reserved for significant enemy action. Maybe played by team of heavily damaged or killed hog.

verbose pas2c for parsed args

issue #458

parentheses for everyone

revert merge w/ Medo change, since it crashes the engine. Access violation line 70 of uLandOutline.pas|line 231 of uLand.pas etc

haskell usability on windows

support ridiculously large maps

add CMakeFile for pas2c, add WEBGL config option

Oops, fix room info on room admin change

dos2unix hedgewars.pro

close branch

move pas2c files in their own directory and add a warning about argument order

ios: fill in CFBundleVersion and CFBundleShortVersionString information better

Build physfs lib before engine

Replay without frontend mode

pas2c is now fully parametric with command line options (maybe unC0Rr needs to clean this up a little)

Simplify ammo menu conditions so it shows up in more states. Should fix issue #465. The part w/ sliding in uworld is main #465 problem.

Fix function prototype

removing the optimisation that caused (most likely) the lua crashes on osx

pas2c can search for inc files in alternate folders (needed for out of source builds)

bad koda

Start work on physfs support in engine

Fix crash in kamikaze

pas2c can read files without changing the process directory

Causes AI fail. Needs testing 'cause at some point, I thought this was needed for portal, I don't remember *why*

- Load teams via physfs - Some fixes which allow Qt to load ini files and icons via physfs

advice from hasufell

pas2C is slowely becoming parametric

oups

merge with default again

strip bad line

let's start to introduce bugs in haskell stuff too

merge .18 lua

Better place for SendUpdateOnThisRoom

Simplify ammo menu conditions so it shows up in more states. Should fix issue #465. The part w/ sliding in uworld is main #465 problem.

Send notification about 1 player in room on room creation

play nicer with system flags

leak

avwrapper needs to depend on hwengine not on ENGINECLEAN

this version of tremor requires a nil check on close_func https://svn.xiph.org/trunk/Tremor/vorbisfile.c

merge from 0.9.18

*sigh*

more fixes

Script typos

update lua (remove duplicate strings, esp in fr.lua - mostly my fault - and add a bit more escaping to the crude script)

5 files that fail to load in libpng1.5 - ran convert against libpng1.2 then pngcrushed 'em to strip for good luck

many osx sparkle fixes

remove mobile ifdefs, replace writeLn's for WriteLnToConsole

Wee, now frontend is able to load translation file

fix name

merge from hedgeroid, includes Medo's work from GSoC

Added tag 0.9.18-release for changeset be11c26a3a0b

Small fixes to b-day image. For next year I 'spose

Removed tag 0.9.18-release

Backed out changeset 5d00c28059e3 - enable the feedback button again

Fix 0.9.18 desync: CreateNetGame() slot creates signal-slot connections from hwnet to hwgame. The problem is that this slot is called asynchronously using queued connection, and hwnet could send some signals to hwgame before hwgame object is created and connected. Changed this to direct connection. Also changed connections to hwgame object to queued, but this is unrelated. Sorry, it is frontend patch. Maybe a little delay on server side could help, but not much, as tcp packets could get glued on client's side, and that greately depends on pc and internet connection performance. Frontend should be reworked to be safe for queued connections, as it is extemely dangerous to have a mix of queued/direct connections.

merge again

updated Info.plist

merge with 0.9.18

small it.txt update

this should fix the highlighting failz with non-lowercase player names like the one CheezeMonkey ran into. there is a workaround: in the user dir put the playername in <playerNameWithCorrectCase>_highlight.txt

Added tag 0.9.18-release for changeset 2f203395baca

double cleaver rotation speed, also make spin direction dX dependent.

Slight update of russian translation

Choose first unused color for added team (addresses issue #431) + other small changes

add SDL as an dependency

let animation objects delete themselves after they are not being used anymore PS: I don't like that we create new animation objects every single time before a page transition is done, I'm sure that can be done in a nicer way. But at least we're not keeping those non-reused objects around forever now...

revert tremor back to a version before koda broke it ;p

more like here

apply unC0Rr's fix for 435 to landscape and non numbered ammomenu

Fix issue #435, and also unreported bug when 2 or even 4 entries could have selection at the same time in weapons menu.

these files had the executable flag/permission set

Clear hedgehog's gear Power value when switching. Should fix issue #446 (not tested, but looks obvious).

Oops, fix room players list emptyness

This should cover all entries from issue #438

Fix cake splashing bug (issue #429)

No hacks! Fix issue #437

fix for issue #441 ("Cannot overwrite default weapon set 'Default'!" message when no change to weapon set was made)

Set minimums on a few values to avoid camera zooming out past them. partly issue #430. Might be worth defining a new constant for this.

eh. might as well toss this in for reference purposes

Fix bad loc calls in campaign, rope training. Regenerate lua. Untested.

fix for the root cause of issue #434 (previous pages being visible in the background)

issue #445 spin math

disable F5 key and data refresh

rollback of r08642c7da4a3b5e05be51a8b45995e799bbc4bbf ("add DLC button to net game room")

finally videorec on osx

I hate Windows and it hates me...

add surname to credits

support video recording on windows with automation and headers

enable png support under win32

hgignore and skip one config file for win32

download SDL dlls if not present

update SDL headers for winutils

Make explosion look depend less on fps

fuuuuuuuuuuuu don't use stack checking

missing nil test

Flag script parsecommands to avoid echoing to net

Get rid of C-style operators

better?

Ok. Seems to me if you disconnect on any page, you should go to the main net page, since presumably you were in some part of net play. I think this should avoid ending up in a "lobby" after disconnecting

lupdate -no-obsolete project_files/hedgewars.pro

tweak tab styling

tweaks to win build script, hedgewars.pro now supports win32 target

tweak tab appearance to try to appease koda

forgot modality for this widget

disable feedback button for now

set window modality also for custom dialogs, small text changes

QMessageBox overhaul: unify buttons, style and appearance of info dialogs, fixing a few typos and return values along the way

add standard copyright header

don't try to delete a default scheme

Completely arbitrary tweaking of tunnel values (avoids a nil) - still needs smooth curves (probably a target dx/dy to aim for, and slow alterations) and taking less CPU. Also disable unused function in Highlander

- Fix desyncs triggered by AI - Assert for valid input in /timer and /setweap

Check cake and air attack again if walked far from initial position (not tested)

Track targets better in multiattack mode

Mark places where tried to jump, avoid too much of thinking

*sigh* revert the multishoot thingy. worked fine in my tests w/ smine and cleaver, screwed up deagle. need to find out why, but sleepy. for later

Someone should look this over to make sure it should stay in

Disable jiggling of cleavers 'cause it just looks odd. Adding a constraint based on proximity to portal is an option too, this was just easier.

Turn off freezing in multishoot, unless unc0rr can come up w/ a good reason why this was here :)

0.9.17 -> 0.9.18 changelog

crude workaround for problem inu reported with sound button

ok. for some reason, this now works without problems. weird. (reenable smine/cleaver alt)

Fix include

Fix build

Fix knockball

Workaround over QIcon failing to load from physfs

- Show unready status in icon - Fix bug with search for player in model by nick performing "starts with" test

I like this condition for home run better

Better error handling

skip all dx/dy mod if Power is 0

Tweak TestDesertEagle. Bots should prefer direct shots to shots through land now, but I didn't test that yet.

cut down on excessive checkins in some situations

Remove slot overcrowding, disable angle detection which isn't doing what I want.

Don't accept ROUNDFINISHED message twice. Fixes game hangs when half of teams quit game.

Try to prevent a situation where hogs embedded in other hogs/barrels/cleavers get stuck, by checking for gears overlapping on Y

Also shove using shotgun, switch off hat when not active hog

First pass at cleaver.

Two cavern templates which aren't horribly long to generate, produce pretty varying maps, and allow 48 hedgehogs gameplay

Fix crasher in TestCake

Switch to vector library for arrays

small tweak. (reverse mouse wheel directions for color change)

Convert ColorWidget from QWidget to QFrame and make use of The Box Model(tm) in stylesheet

UNBAN implementation

add Randy to extended credits

french translation. primarily of the campaign.

Better use random number here

no. still doesn't work right

Please pas2c

- Enable chat context menu actions - Load/save friends/ignore list

Don't ask for full rooms list on part/kick

Reset nickname so it may be reused while old connection is still hanging

no. still doesn't work right.

Knife is still broken, but so koda can fix it...

Load friends/ignored nicks from file

Room players list

A bit more on the knife. Also add missing files to CMakeLists

Data for copying throwing knife to Land once it hits.

Bring back sorting

Bring icons back

Set default collision mask for gears at currenthedgehog X/Y to FF7F, expose mask to scripting as well. This should resolve the collision part of bug #420

Further work on moving to players list model

Simplify file loading procedure

Start moving to players list model.

No commit message

- Fix warnings and hints - Hide "Converting the operands to Int64 before doing the add could prevent overflow errors" kind of hints as pretty useless and annoying

Show more statuses in icons. Need further work: - Better icons (specially registered vs unregistered) - Share information between chat widgets (now room widget can't show registered status because recieves events for users when user list is empty)

Move hedgehog's step routine into separate function, use it in both hedgehog and ai code

use cmake OPTION for arguments and further cleanup on CMakeFiles

revert since I didn't quite get this working smoothly enough. was close though. perhaps some other time. Shame because calling game tick less frequently can save a lot of CPU

Fix some hints

Shutup pas2c

vector2Angle function which converts vector to angle from -2048 to 2048

Always run simple game on medium maps

Oops

Fix framing

- Keep track of room name so correct name is displayed when you become room admin - Don't rename rooms if client is > 0.9.17

only accept RELASE and DEBUG build type configuration

another little tweak

sdl_extras updated/fixed (is this file still needed?)

forgot a few checks from rev f40c65ae3eab

force a DEBUG build when HW_DEV is true, some CMakeLists.txt cleanup/commenting

blindly trying to fix the android build

nicer debug log visuals on ios

switch the Tremor implementation from the Cocos2D one to the lowmem-no-byte branch and let's see what happens

update ios project file again to reflect SDL2 renaming

Hedgeroid: Updated base locale

issue ENGINECLEAN only when fpc < 2.6

Hedgeroid: Update to new NDK toolchain (requires NDK r8b)

updated ios project file

frontlib+Hedgeroid: Added support for the new client flags (chief, admin, reg)

Treat init expression in parens as just expression instead of array initializer when there's only one entry in expressions list

frontlib: Add/change comments to correspond to recent changes in QtFrontend and server

New hwSqrt which is up to 8.7% more efficient than old one on synthetic tests

Merge

Italian translation update

Italian engine translation update

recognize client-flags h and u, ROOM_CONTROL_ACCESS will be ignored from here on

client-flags: make code easier to read/prettier; add parsing of flag 'a'; add warning in console on unknown flag; ignore ADMIN_ACCESS

'h' status for room admins

Reset to default colors button

- Some improvements to tr() calls - Translate some entries in russian and english translations

- Fix some warnings in frontend - lupdate

Polish settings page a bit

More consistency in terminology

merging in campaign updates - please test

Fixed grammar/vocabulary and improved balance Mission 7: Added more pickhammers so that it's harder to run out of them, added more weapons to the AI Mission 6: Removed reset possibility, added sticky mines, more weapons for AI every six turns Enter commit message. Lines beginning with 'HG:' are removed.

fix for issue #293 : "rope stuck after picking crate"

fix a segfault related to tcp servers deleting themselves without removing themselves from the internal server list first. (e.g. happens if game fails to start due to missing hwengine binary. a second start attempt will lead to a segfault, even if you correctly install the binary.)

retain frontend effects setting exiting/leaving settings

Fix some warnings

Stop messages without possible desync on load from save

I didn't want to do this since it seems less clean, but... moving the stats-fix into CheckForWin, since that function is the one sending the damage stats (whyyyy?) therefore it's not sufficient to update stats after calling it, some of the stats won't be transfered to frontend then

Show who is the room admin on join (no tested, also I don't like how it is done via server warnings, but it seems there's no other solution compatible with .17)

skip second CheckForWin if water wasn't raised after first one

fix multi-shot related game ends leading to incomplete stats, fixes issue #372

More Qt-ish code, fix couple warnings.

Unset room restrictions on player/team joins when changing room admin

More precision

forgot to add back c96ff1a053d0

fix for issue #376 (embedding barrels in ceiling)

Fix line endings, add missing amMine entry

teleport hack fixes: * don't let hogs fall into other hogs, barrels or other gears * stop animation on damage (doesn't work with invul, sadly) * don't force waiting for ground-contact in inf attack mode * fix initially placing hog right next to instant-mine causing bugs

adjust velocity when entering/exiting the 4x routine

Let's try *4 instead. Not nearly as much of a win, but might be usable.

So, unc0rr won't let me revert to pre-e496587db93e, but reverting db731c523653 makes the rope less-sticky-enough to actually be usable in an ordinary game without my screaming at the monitor as I drown for the nth time...

if this doesn't work I shall cry like a lady

I assumed NO_VIDEOREC would be set if ${FFMPEG_FOUND} was false. doesn't seem to be the case.

engineclean returns

Not sticky rope

perf tweak

LAND_HEIGHT/LAND_WIDTH need setting later now

Correct snow fall/rotation (matching visual gear)

Oops

Rope fix without hacks.

oops

remove checks from c4272519b128, ed7fecd0f5fd just hides 'em instead.

hide health bars of dead teams

Differentiate videos from demos - navigating between them was too confusing. BTW, why is this on the front page, instead of next to the demos button?

fix parsing of 'if': identifiers can also contain underscores

fix parsing of 'if'

clean up LoadImage and UserPathz/AltPath/etc related redundancy by introducing 3 new functions in uStore.pas

* don't build moc for campaign.h * added campaign.{h,cpp} to hedgewars.pro

oops

use old approach for printing gl extentions for pas2c (less complex/no StrUtils dependencies)

min -> qMin

don't query/print GL_AUX_BUFFERS if video recording is disabled

print all GL_EXTENSIONS properly to logfile (should a;sp fix build on systems with compiler/lib versions that can't implicity cast PGLubyte to PChar)

Allow adjusting bitrate so that I can get a somewhat usable webm video. The audio is still tinny and unlistenable. Configuration option for that might be helpful, or just adjusting defaults in the wrapper.

add 'a classic fairytale' campaign to cmake install

dos2unix newline fixes on 7 (video recording-)merged files

Move some options to the second page so first page doesn't look ugly on low resolution

neglected stuff

Checking merge against latest trunk

preliminary creeper (not yet functional)

new grave: dragonball (incl. svg) by Randy

tiny (probably) optimisation

A few more operators. Committing in case unc0rr wants to fiddle.

isZero appears to be never used. Use it in a few obvious cases and add web variant.

Fix library installation in win32

disable snowball damage, by request of sheepluva

remove a redundant assignment; whitespace fixes

This should work better

fix build for me

Make ffmpeg optional for frontend

Small fix

Merge Stepik-777's video recording gsoc project

Starting to rewrite uFloat routines to avoid QWordValue - in the interests of JS which may get uint64/int64 in the spec in the future but does not have it now.

Merge

shutting the windows/pas2c build bot up: pas2c seems to fail parsing 'not' after a logical 'and' or 'or' (if no parenthesis)

Nerf X component a bit, allow knocks of nearby targets and upward kicks of overlapping

so unc0rr might replace this all. but anyway. fix copypasta.

shoppa hack, take... 4?

another shot in the dark. still w/ no input from shoppa players

shoppa hack guesses. continued. let's assume there's a small Y component.

another shot in the dark. let's assume they expect to control their direction as well. this might be the *wrong* direction...

hack for shoppa players, take 2. take into account sides, and a guess that a "slide" involves no upward movement

Hack to try and appease the shoppa players

reducing this value is sufficient to ensure crates drop just below top border or a girder

Fix throwing things off rope, also make throwing things a bit more generic and gear density dependent (so you can throw mines further, and also throw dynamite a little).

Allow escaping from tight spots

Disable workaround, as it still makes server crash and hung clients are hidden from players anyway

Ensure crates can spawn just below the border on a bordered map.

let's see if mikade will still accept this at least

make cheating a bit easier (mikade insisted). Also, try flipping dust for a bit more variety.

oops

Hey. How's this? It makes it harder to get stuck in the vertical rope position, prevents the wall trick, and also I think makes it easier to unglue a horizontal rope?

fromdos + fix end of turn velocity

An attempt to run main rope code only every 8th tick: - A big win for inner loop which is O(n^2) and thus it takes 64 times less cpu now. - Look and feel is almost identical (well, to my non-pro view) - Yes, the speed is limited to 7 px per accounting tick which is potentially very bad to collisions - Ruin shoppa

Move rope code to separate unit

Fix formatting, reduce border sensitivity

Hedgeroid: Fixed map preview again (might be a JNA bug)

also needs exclusion here
