Remove switching of hog's hat to chef. do it in draw instead.

Load and show local teams list

Revert hog tinting from rdb65298717da since it wasn't sufficiently complete for a release. More sprites need converting, and there's a slight bug in hog tinting, for away hogs with hats I believe.

- Implement getTeamsList (not tested) - Some small fixes

allow toggling ammo menu while NoTeamOrHH, as suggested by unC0Rr

Filter out garbage from themes list

find and add lua tests automagically

flib provides theme icons, qmlFrontend shows them

allow hogs to repeatedly enter portals placed on the ground

Themes model, also add some files I forgot to add previously

some unfinished stuff

Quick Game PoC

another small rendering tweak/fix

Getter and setter for seed

simplify {$IF that pas2c did not seem to understand

More refactoring: move PoC preview getting code into flib

also fix top/bottom and side-by-side rendering (got also broken in webgl branch)

Some refactoring

fix stereoscopic rendering leading to screen "running away to the left" since webgl merge (due to bug in webgl branch). reason was incomplete change of name/scope of variable stereoDepth -> cStereoDepth

- Get rid of engine's PathPrefix and UserPathPrefix - Some refactoring

fix mapgen of other scripts too

- Pages - Animations on buttons hovering

use constants for mapgen, expose those to lua

flib: - Ability to pass raw data via IPC qmlfrontend: - Pass message received by callback through event loop to handle it in main thread - Get preview image from engine on button click and render it in Image object

some more splash code tweaking/fixing

Move away from passing shortstrings into C code, now IPC works

tweak splash position

- Remove --port command - Some refactoring here and there - Try to get preview from engine, which doesn't work due to some ABI mismatch, probably shouldn't try to pass string255 to pascal

☹

Strip some HWLIBRARY ifdefs

climb home training/multiplayer

- More flib IPC routines - Rework engine's uIO to use new IPC mechanism

Make it a bit easier/safer to build ice bridges

- Fix arguments parsing in engine assuming paramcount > 0 - Pass "--help" for testing

update with new winners

Let's get it started

- Revert try to add local team on rejoin - Don't allow more than 8 teams in local game widget

This should make frontend aware of your own teams in game on rejoin

Also pass maze_size parameter to perlin generator in game mode

Also convert the message if current team is gone

rename of variable typo for readability

ok. that's weird. I wonder if I was having non-clean build issues last time I tried messing with this. that could explain why my changing offsets didn't do anything.

Better diagnostics in log, even though it shouldn't matter anymore

Fix map contrainer widget look in russian locale

Fix issue #813

- Support for pausing multiplayer games - Some code cleanup

Add separate option for perlin gen

don't render crosshair/laser during kamikaze

comment out some debug output code

part of patch in issue #803 (ty) - this hopefully should fix issues with cmake Makefiles trying to run "Qt4::lrelease" in the shell

Apply new distortion on maze gen

Smooth perlin's outline

add bug reference to explain the qt version check on osx

I can't read. sry

contradiction with a hint of BS

this should fix the cmake 3.0 issue. thanks to Spacey for reporting

tweak test

add test I used for bisecting

Make team disappear after 3 turns in 'gone' state

Fix issues with unsynced F and G messages being lost if current team which is supposed to convert them to synced f/g quits

Finish implementation of ability to take control over your team after being disconnected. Completely untested.

Fix build, and also make protocol a bit more consistent and flexible (only in docs though, to be implemented)

2x2 to avoid engine bug

couple of custom sprites for mikade to override in a lua sidecar if he wants to

Inform engine if player is back after being disconnected

clean up halting a little

enforce style on message boxes some more

fix gl2 build, further rendering cleanup WIP, also new chat command: /debugvl

tweak how chat lines are rendered

huh? me? nono, don't mind me. I'm just here to clean up.

some rendering tweaks

fix possible engine crash that a lua script could cause by passing an invalid geartype to addgear

tiny lua documentation fix

uWorld does not require uMatrix anymore

fix hint and gl2 build. NOTE: this does not change that GL2 segfaults right away. that is an issue that dates back at least 50 commits, but most likely even back to the webgl merge. I guess nobody actually tried to run hedgewars in GL2 since back then :P

RAR: cleaning up a bit of the IFDEF-clusterf*ck

Fallback to old heuristic if not pit position

update viewlimits after screen/window resize

Allow barrels to spawn in U-shaped pits in stable position

whoops, forgot to include this file in commt

superminor tweaks

<koda> wut, chats as commit mesages?

"<unC0Rr> could also refuse to update textures when land changes if the tile isn't visible" You had me at "refuse" <3

figure out visible land tiles in advance

some minor tweaks and stuff

darken wrapped areas, which was a very nice suggestion by nemo

use cScaleFactor where I incorrectly used the variable zoom in the past. i was young and needed the money

here a personal experimental mockup of how I imagine wrapping world edges should look like. bouncing one could be similar just with mirrored stuff. please test and share opinion. note: you might wanna disable auto-cam

small hat loading tweak

load the girder.png of a theme a maximum of 1 times (minimum of 0), instead of once per generated bridge

clean up image loading a bit. gets rid of useless "Passed NULL data source" or PhysFS file not found errors

committing patch from issue #798, as requested by unC0Rr

fix cabal build (on linux)

fix for "Unexpected semi-colons in conditional" issue, as reported by YuGiOhJCJ (see http://www.hedgewars.org/node/5860 ) big thanks to burp for helping to identify and fix this issue

Some further work on map optimizer

tweak untint a little (especially in connection with GrayScale)

theme configurable sudden death music. untested

allow teleporting outside Land[]

escape info message arguments, fixes issue #801: Frontend parses INFO command output as html

collision indicator on failed girder placement (especially useful with rubberband I guess). still needs some tweaks but I am going to bed now :P

disable these weaponset flags. they bug up highlander and otherwise have no useful impact on the script.

get rid of fpc warnings/hints

Fix some of issues found by coverity

Official racer challenge map #8

Inform frontend of lines which didn't change anything on the map in advanced drawn maps mode

Fix some pas2c engine warnings

Count number of pixels changed during draw

Small optimization (no need to draw last point of the path)

Oops, should stop coding at night

Fix fpcrtl_strncompareA, also replace strncmp with memcmp for more efficiency

Support OR operator in $IFDEF. Fixes pas2c builds.

rolling back the rest

rolling back (most of) lua 5.2 compatibility patches. hopefully that will unbreak unC0Rr's lua issues for now.

sekret feature (test commit)

- Increase limits on number of mines and explosives in game scheme - Stop trying to place mines/explosives after 4 fails to place in row

Drawn maps optimizer - first steps: - Break paths into segments

Fix crashers in rc plane code

Merge

don't search for lua 5.1 anymore

Don't activate invulnerability/vampirism between shots of multiattack weapon

minimal changes for compatibility with lua 5.2, thanks to v4hn for fixing standard library loads. note: ALSO compatibile with (internal) lua 5.1, until something bothers to upgrade bundled lua version

Fix typo leading to crashes

Add race type detection

- Fix bug with infinite rounds in racer when a team quits mid-game - Don't allow placing waypoint right on top of previous one, prevents accidental double waypoints - Don't limit maps on number of embedded waypoints

Fix new generator on 32 bit arch

No more occasional long straight edges

Spelling corrections

Optimize out path closing point for one point paths

Racer challenge map #7

Official racer challenge map #6

merge

param for original highlander mode - right now just allows getting another copy of a weapon you already had, but had used that turn.

Send updated info on map switched by voting

Fix condition

Fix build

- Fix applying vote result - Votes expiring (I'm sure it doesn't even build, but my ghc is broken for now, hoping for the best)

Fix script

Racer challenge #5

Some fixes to voting + small refactoring

Better detection

hm. I think I forgot to commit this when adding speech bubble change

Fix warnings

- Limit outline to leftX/rightX/topY instead of LAND_WIDTH/LAND_HEIGHT - Fix most of templates which could produce self-intersecting polyline as a start for distortion - Fix parsing in templates editor

- Make sure distortion doesn't move fill point to other side of segment, this prevents corrupted maps - Some adjustments/comments

Process segments from last to first point too

Prevent intersections with segment from last to first point, adjust size of details

Fix div by zero error in new generator

Greedy approach: divide while it divides

No self intersections, except for weirdness between first and last point

Fix detection of intersections, still need to check if passing any point in move, but result is already okayish

More math, implementation is nearly complete, just still have an issue to resolve

Some progress on new generator

Move template-based generator into its own file

Some optimizations

Fix perlin gen on 32 bit arch

- Room save/load into/from file - Vote on map (not complete implementation, also voting itself is still buggy)

Allow to save and delete room config in room

By request. Allow lua to make random things "talk". I'm not sure if this is a good idea, buuuut.

Feel free to revert this one, was just screwing around with stuff from before. I kinda like it and figured committing it was the easiest way for you to look at it. http://m8y.org/hw/perlin.png

this is fine right?

Tweaks and tweaks

- Rework FillLand - Optimize fade() function a bit, don't call min() function - Only leave parts of land which touch bottom border in perlin mapgen

as suggested, precompute to avoid use of double

Experiment: enforce a plate at bottom so the map generated is more connected

Some optimizations

Strip Z axis from calculations

Setup leftX, rightX and topY

Some tweaks to perlin generator

Add randomness

Perlin noise generator untweaked, temporarily replacing maze generator

Racer challenge map #4

merge

don't stack bye/teleport sounds of hogs (when a team is gone)

Don't run two engine threads simultaneously

Don't call halt()

Remove game/preview functions split in library mode, just let normal procedure run instead: - Remove tons of HWLIBRARY ifdefs - Override ParamCount and ParamStr to let GetParams work - Small fixes here and there

- Fix crasher in doStepSniperRifleShot - Fix hwLibrary.pas dependencies list

Make it build as library

Only draw border for solid land

Script might well override a static map, but can't risk it not doing it, and preview completely failing. Better to just not try it for static maps. Some script cfg might help. Could also avoid unnnecessary preview regenerations even if the script was doing nothing at all.

merge

always update. a bit inefficient, but scripts do weird things.

Fix "don't know how to make hwengine.pas" error

no idea what happened to this image... it seems like I'm reverting to most recent revision O_o

pass --prefix to previews too

Use all pixels, not only 8x8 areas

AI doesn't skip till action on the map stops (mostly dedicated to highlander) + various small tweaks

Oops, remove debug stuff which hid the feature

move the freeModule too, couple of style tweaks

fix molotov sprite too

tweak dynamite sprite (pixels at frame border, leading to visible filtering artifacts when zoomed)

merge

change how textures from non-power-of-2-width textures are filled. this fixes e.g. the vertical lines appearing between Bath theme's horizontL

minor comments fix

add preview init to tunnels too

fix remaining alpha pixel issues (explosion landbacktex borders etc

use data not text, so DLC doesn't get an *

Allow lua drawn maps (shoppamap, tunnels, diagonal maze etc) to generate previews.

Official challenge map #3 by 1937barcelona

Don't rewrite server ini file too often

Fix tinting of AI kills counter

Should never use State like this, since some states aren't synced (thinking state for example)

allow switching through hogs in reverse order with PRECISE+HOGSWITCH

Fix issue #780 (copy-paste fail)

Fix setting lc_endluatest result

Reduce number of warnings in pas2c-generated code

Fix build

What about exact value?

In stats-only mode: - Don't load all sprites - Don't use sdl_ttf - Don't load binds

Only check alpha channel like BlitImageAndGenerateCollisionInfo does

NULL PChar is okay

pngcrush on this file which will hopefully be cleaned up at some point

Fix read of freed memory found with valgrind

Use strchr instead of strstr with specially constructed string255 struct (not tested)

- Remove few PAS2C ifdef's - Load localization

Fix binds loading

- pas2c recognizes typecasts in initialization expressions - Forbid incompatible pointer types - Fixes and new functions to fpcrtl

Small fix which makes pas2c engine successfully replay demos

It compiles \o/ Doesn't link yet though, need to implement new rtl functions

fix lq rope being always drawn on screen with same width regardless of zoom

fix misleading indentation

Even more explicit type conversions and other stuff to help pas2c use ansistrings

Implicit type casts to help pas2c

Implement a bit of astring

Pas2C recognizes ansistrings

Fix build with old base package

disallow sinegun to penetrate solid land

rolling back my PChar stuff, because unC0Rr improves string handling pas2c instead <3

Merge

get rid of hwpow. ~so long and thanks for all the wtfish~

Fix tons and tons of pas2c warnings (but still not all of them)

fix indentation of previous commit and simplify rc-plane's angle-fix after portal code

Drop support for other string types than string255

simplify rc-plane's angle-adjustment-after-wrap code

CMake checks for haskell modules needed

update FSF address. note: two sdl include files (by Sam Lantinga) still have the old FSF address in their copyright - but I ain't gonna touch their copyright headers

whoops, lost a space

fix a relevant warning I caused by accident

fixing the remaining PChar issues pas2c ran into to this point, now it stops because of being unable to deal with "set of char"

yo dawg, I herd you like PChar...

remove obsolete type conversions that messed with pas2c

fix some string related pas2c issues

use uConsts rather than including config.inc more than once

add travis dependencies

fix for issue #777 (IceGun: Segfault when freezing water, with rqBlurryLand enabled)

- Cut actions array instead of performing full copy, when it is possible - Fix use of uninitialized attack parameters struct (existed for years, and could maybe explain some weird ai behavior)

Tiny optimization

don't allow getting 2nd copy of wep you already have, prevent gaining banned weps even if set to infinite in scheme.

Actually do some actions when flood detected

Define some boundaries to detect events

More work on flood detector

Fix build

Official racer challenge #2

- Start work on flood detector - More agressive joins flood protection - Also fix some warnings

aaaand remove switch

tweaks

Implement kick voting

This should help server bypass malformed replays

remove a few weps I missed. forgot I'd uncommented prior to a diff I'd done earlier

AI always activates invulnerability and extra damage if it has them

Make highlander configurable using weapons, commit weaponset mimicking old values

unbreak build. didn't test changes

Implement 'voted' function

Even more love to pas2c

use CMAKE_CURRENT_SOURCE_DIR consistently

Must not code at late night (fix sanity check)

- Add SCHEME which is needed in room config - Fix replay of games on maze maps

Some basic sanity tests for replay files

confusables.txt to insert query converter

Handle chars and not bytes for usernames :-p

turned out this blocked CJK characters too. stick to ASCII control char ban only, do NOT include UTF-8 control chars

hide complete IP of other users, when non-admin requests player info. showing the first two parts of the IP was kinda pointless to begin with (what for?) and has recently lead to increased abuse and lobby flooding due to bots collecting/posting IP tracking information

Use zlibFormat

disallow control chars in player nicks, thanks for burp to helping making the list more complete

- Implement /callvote

- Allow delegation to specific person in fixed room - Remove redundant check in DELEGATE handler

Don't delegate special room to another player when owner quits

More robust implementation of decompression

Small update of my voice-pack Default_ru

actual fix

Fix uGearsHandlersMess.pas changes lost in merge r1c02143bfe9c. This seems to only include the drill rocket fixes ( re0dd66b2e73b and r8db0c56f7e2f ) as well as the initial cake push ( r8786d4ac9e0b )

Fix server producing unreplayable records

use new API for changing GameFlags

luaAPI: * add paramater count checks to gameflag functions * add GetGameFlag(gameflag) for checking a gameflag's current state

Fix detection of mapgen

Merge

This adds idle hog tinting. Active hog tinting still needed.

let log know when a test finished properly, so that an unexpected termination (segfault, divbyzero, etc) is easier to tell apart from test fail

* fix divbyzero found by GetGravity test (cWindSpeed was used where cMaxWindSpeed should have been) * make GetGravity return same integer value that was given by SetGravity (by rounding away precision errors rather than just truncate) - a problem also identified by the test :P

test for GetGravity and SetGravity

add a test based on unC0Rr's suggestion. still a lot of mess and redundancy involved, sry :P

Implement drawnMapData function so checker could check replays with drawn maps

drill rocket test

new cmake option NOVERSIONINFOUPDATE -- to be used if source is in a git/repo that is NOT the hedgewars repo

remove DroidSans font from source dir. it is unused afaik and also wrongly included in the source tarballs

no idea how I ended up forgetting about the offset I need for same position in different rows (in 1d array); also remove obsolete comment

small tweak/hax for blurry land to make tile borders vanish (when clamping is off)

add travis tests for the two new cmake options

(experimental) merging the new procedures for different pixel representations (1D/2D arrays) into a single procedure with the algorithm and two procedures for the different mapping. - because redundant code sucks (at least twice)

fixwhitespace and dos2unix

(experimental) make the mysterious borders around land/hats/etc that appear on zoom vanish note: not applied to everything yet note: I'll probably merge the two functions that do the same thing (one for 1darray, one for 2darray representation of pixels) into a single function

partial merge of the webgl branch This commit contains the new pas2c conversion tool, the pascal to c build structure and the opengl2 rendering backend. Patch reviewed by unC0Rr.

Fix checker logon process

changing build files without testing the change is fun, isn't it? especially for trivial things that would take less than 10 seconds to test :p

Make poison damage possibly variable (might as well since effects is a count). Scripts might find it handy.

Add check for gear kind of hedgehog on invulnerability effect. This probably fixes bug #766, is similar to change in previous r2a1483d91977 and was introduced by r7d925e82e572

well. let's fix this at least - only apply to gears that are actually hedgehogs, not just ones associated with a hedgehog (which can be pretty much any gear since damage tracking was added)

Convert some ansistrings to pchars

drop redundancies for lua and physfs

fix linking physfs after a run of cmake

happy 10000th commit also fix the travis build by adding a system physfs library

position "finger"/pointer over current hog above tags

style tweaks

update copyright to 2014

move room state filter

unCORr likes PChar arrays

In special rooms game starts when all players are ready

* allow telling cmake where to find required fonts in system when user supplies the paths, as suggested by unC0Rr, e.g. -DFONTS_DIRS='/usr/share/fonts/truetype/wqy;/usr/share/fonts/truetype/dejavu' * the build system will use the paths to lookup fonts and install those not found * the engine will load the paths into physfs (mountpoint /Fonts) to make the fonts available at runtime * overriding fonts in packages should be possible again now

allow engine to use symlinked fonts. disallow packages to "overwrite" fonts

PhysicsFS 2.0.0 seems to be sufficient; also fix a typo

add compatibility for physicsfs 2.0

oops, fix build

Also define default value of THEME

simple mechanism to run lua-based test cases. experimental - I will back it out if it turns out to be nonsense
