- export/import strings to .tsv text file
1e1af9db1
Allows for exporting strings to a spreadsheet, text editor, or other program for modification, then importing them back to ZC.
The first row of the
.tsv
(tab separated values) file are the column names, followed by an example row to designate where the first three lines begin and end for each string (but you can add more lines than that).For best results in a spreadsheet, "Freeze" the first two rows and use a monospace font for the "message" column.
Example: https://docs.google.com/spreadsheets/d/197-NSvNQJ174Ri9GVlxYDX4oFp8w1SZbmOXuDohKZZk/edit?usp=sharing

Bug Fixes
- prevent clock shifts from hanging the program
b379a0ed9
Allegro 5 doesn't use a monotonic clock that ignores suspended time, so day light saving shifts or even hibernating your computer can result in Allegro trying to do so much work to "catch up" that it hangs the program. See liballeg/allegro5#1511 for more.
- shift key input no longer accidentally ignored
c92f096a0
- passive (non-button) items not respecting "Usable as a Bunny" flag
84d7f07e8

2264bb083
- issues with numbers between 0 and -1
1b44e3b2c
- swords not updating properly, sometimes
915670436
- old quest subscreen minimap titles overlapping
dc548320e
- placing flags on layers not marking the layer screen as "valid"
8c74b7296
- ensure file is closed when qst fails to load
c702f24fc
- retain monitor resolution for fullscreen mode
981c6c1f9
Previously, the maximum monitor resolution would be used when using fullscreen mode. That was bad because it messes up the window layout of anything else on that monitor. Now we create fullscreen displays without changing the resolution.
Also, no longer destroy and recreate the display to change fullscreen/windowed mode. Switching between is much smoother now, and the code got a bit simpler and safer.
- changer ffcs counting for trigger groups and similar effects (they shouldn't)
e9d91d8fa
Player
- Music not properly changing when using some warp types (ex. SCC warp)
0aef5384b
- extra pushing allowed per screen
8a798d0dd
- cheats menu being greyed out when it shouldn't be
b24044c87
- new respawn points not accounting for dmap offset
d90410dcd
- initialize fadevolume to avoid undefined behavior
437c27b25
This fixes a bug where music would randomly be silent or extremely loud.
Also, cap the volume used to play music to 255, to avoid ever playing it so loud again.
- set volume correctly when music changes with only fading in or out
9274a675b
For example, if the new music has a fade in frame duration of 0, and the old music has a fade out frame duration of >0, then the new music would incorrectly have its volume stuck at 0%.
- menu bar unaligned with dropdown due to menu using int scaling
f8222be89
- Swim speeds not being saved to save file
2bbf51a02
- spotlights with color setting '0,0,0' or tile setting '0,0' now function
8da01272a
- Allow throwing lifted object without validating cost
498f70f46
- thrown weapons now should hit enemies that they land on

7601d2fb7
- use more performant throttleFPS instead of rest in system menu
0de39b360
- remove accidental double compilation for global scripts
f30fd983f
- draw to correct bitmap when showing button clear prompt
6e204d4fc
- minor replay determinism bug for subscr_item_clk (selector animation)
825844706
- only assign save path just before actually writing to disk
603e96444
- call saves_do_first_time_stuff when changing slot qstpath
db4cf98c2
- handle edge case when changing unplayed save file qst
79564453f
- prevent calling dmap script twice in scrolling dmap warp
e8edc34e9
- set previously unset save_t write_to_disk in all places
adca2b376
- not showing error dialogs in title screen, and unbreak -only switch
c32a29d1d
- clear spin state during screen scroll
7ca93107b
This avoid a ghost sword visible during scrolling, and also prevents a nasty bug where the player's action state would be frozen until hit.
- prevent crash in save creation by resetting global vars
2b3c4119d
When a game is loaded, many global variables are initialized to a known state. These variables were not reset when the game ends and returns to the title screen. However, save creation happens to call code that checks the active subscreen pointer, which was invalidated. Accessing this could randomly crash or corrupt the program.
Now, these global variables are reset also just before loading the title screen.
- prevent failing to save after continue
870510c96
- lift glove 'disable item use' not stopping sword SFX from playing
3e6fe6e05
- remember last save slot position when returning to save select screen
a3bc81309
- [win32] invisible hero because of MSVC bug
511934cea
- remember cheat on continue game
99675afa2
- 'Custom Weapon' itemclasses rounding down step speed
8f4b63428
- restore option to scale display to full window size
b618eb983
This broke when the display was fixed to only show at the correct aspect ratio. Default is still as before, but now the "Force Integer Values for Scale" option works again.
- still allow for game area to be stretched, ignoring aspect ratio
381583118
- ignore gamepad input when window is not active
646ef8f08
- weird newer movement edge-case
0dd159abb
- opening spacebar map triggering some secret effects on the current screen
c1d9c1dca
- lens unintentionally making enemies sometimes invisible
1a9273955
- lens unintentionally making enemies sometimes invisible
111569113
- Divine Escape particles sometimes flying in wrong directions
d2472cceb
- crash when running replay without any real saves
f90cb0253
- remove unnecessary absolute path check for standalone mode saves
ed4afb985
- show final game frame when opening/closing subscreen
07dddb5e9
For older quests utilizing none of the QRs related to "cool scrolling", the subscreen open/close crawl would show a version of the game frame that was missing a few things, like enemy or player sprites.
This should allow us to simplify the rendering (no need to render most things twice to a secondary bitmap), and just looks better.
- do not stretch GUI
fad67d962
- tall grass on layers not applying its sfx/sprite
76f952fc9
- fix snapshot with NOSUBSCR not supplying a palette and not accounting for NOSUBSCROFFSET
45bf325cb
- set default volume to 100% instead of 25%
8a4f7cf2e
- prevent grid aligning while jumping, which broke jumping for some old quests
2d8a18875
- for replay mode, whistle sfx pauses game for number of frames proportional to sfx length instead of 0 frames
1f38de5b0
- hero action "swimhit" incorrectly unset due to broken isSwimming() check
8b10722d8
- combo cycling reset too early for animations with frame skips
601cba74f
Turns out this never worked properly!
- defer deletion of sprites to end of animate logic
548c3e15d
This fixes a crash caused when a sprite deletes itself in middle of its animate logic.
- prevent OOB access for darkroom ditherrectfill
07dfbbe3f
When scrolling, this function could be told to grab a line of the bitmap memory outside its bounds, which resulted in a crash.
- reset global variables on continue game for replays
f3b34561f
- actually stop mp3/ogg
994d743dc
Due to a bug ogg and mp3 formats were really just "paused" when told to stop, so setting the volume afterwards would result in resuming music that was meant to be over.
- ambient/background sfx volume not being set
52594bfc7
The recent removal of "digi_volume" made all background sfx play at full volume. Fixed that.
Additionally, fixed a bug in the sound dialog that skipped the first sfx when adjusting currently playing sounds to the new volume. That first sfx is often a background sfx.
- various slope improvements, like fixing ffc slopes
f80e024ca
- fix mirror shield not resetting the last used mirror combo position
2c375403a
- save select screen not showing new hp after save->reset
8d15352e5
- load default quest for sfx when loading replay
4bc56aef2
Quests before custom sfx rely on the default quest providing sfx, but that wasn't being loaded when playing back a replay. So it would either use whatever the last quest loaded, or have nothing, which was the case for the replay test script.
- use correct graphic when holding up purchase from bottle shop
03d123012
- apply BS swim sprites compat rule to Zelda 3000 qst
5f7ab3c23
This QR is applied to all 1.90 quests, but Zelda 3000 was saved in 1.92 and this visual bug was overlooked.
- consume button presses in subscreen menu
23f44b9f6
The subscreen refactor ~6 months ago resulted in button presses not being eaten. One side effect of this was the item selection sfx playing for every frame the button was down, instead of the intended one time.
- ZC menu options render/get disabled correctly
571460f7a
Editor
- prevent flickering for minimap tooltip
69948f334
- Tile editor checkboxes not clicking
983a17add

- timeout of 0 for parser timeout now acts as "no timeout"
975602f22
- 'File->Exit' not exiting
5db531ab7
- 'Scroll to Combo' on screen rclick being offset
5497092dc
- greyed out pasting in string list
f2440669d
- create test init data relative to qst init, not base init
fadfe7d74
This was originally done this way to avoid changing test init data when the quest's actual init data changed, but that maybe is not as useful as the other approach.
Also very simply fixes the problem of screen data (and other init values) not being properly set.
- autocombo/combo pool/combo alias pages RClick menus being offset
d3e276c4d
- 'Open Tile Page' on combos not using the ORIGINAL tile of the combo
7009db89b

- undefined memory write when applying modern quest ruleset
2ed538d97
- lockblock/chest combo wizards not saving 'Use ExState' flag
2a3eb96fd
- some more issues with warp dialogs
e9ab158ae
- warp dialogs not properly previewing negative xoffset dmap map-marked squares
b593e46bf
- solidity preview inaccuracies
723c58ebc
- 'Tools->Combo Flags' bugging out when clicked
53f324ae6
- crash related to 'Scroll to page' for aliases/pools/autocombos
7f8d8236c

7ff03e46b
- handle quest path/title with spaces in package export
432dfe42c
- transparent tiles not drawing correctly in map preview
80f94a9ea
- error message on failure to load enhanced music in the dmap editor
06cee90fa
- skipy broken in combo preview animation
590e9f59c
- combo animations not resetting after using combo selector in dialogs
99ab2ae95
- weapon type names drop down being empty
53cdacc3d
This broke from recent addition of reflected arrows/fire (e3b23aa)
- hide unimplemented enemies
875589f19
- handle error instead of crashing if package export fails
53f7a7253
- stop clearing screen when editing palette
47aaddd62
Since the render refactor, we haven't needed to clear the screen when changing palettes, since this dialog is rendered to a different bitmap than whats in the background.
- 'Load Tileset' not applying compat fixes
0fdad2857
ZScript Standard Library (std.zh)
- DMFS_ constants being off-by-one
7fc001530
ZScript
- 'subscreenwidget->PerContainer' not working
9d7c222dc
- al_rest crashing when using debug feature
6058be2ba

- handle rare COMPAREV2 for x64 jit
0fc3edd39
- sprintf giving a wrong error message on %c
180b66fc9
- 'Screen->SetExDoor()'/'mapdata->SetExDoor()' not opening matching doors
88f2ab405
- grab correct value from stack for POPARGS JIT x64
504f87a71
This didn't seem to break anything, but it showed up as a difference when comparing registers from JIT w/ non-JIT.
- Hero->WarpEx not using dmap xoff when setting continue screen
e21ba53d0
- global var initializers not erroring when non-constant
e1b10e2a0
- escape character " not working properly in string literals
a08d4a149
- invalid character errors wrongly occurring for values 128-255
2cfe2e472
- subscreen widgets not allowing SUB_COLOR_TRANSPARENT to be used
77346b0c8
- class function params with same-name as class member not shadowing properly
5659c8ebd
- class/object destructors stack being offset wrongly
79079c766
- fix Audio->SetMusicLoop() truncating decimal values
c6e7c0205
- compiler crash related to invalid array indeces
f3e3f7ecb
- sanity check for bitmap->isValid() and bitmap->isAllocated()
c07f28f80
- stale data in destructors
6251b0f23
scripted objects weren't clearing data used by the destructor when being cleared, leading to future objects referencing the stale data if they didn't have a destructor of their own to overwrite it.
- generic script item collect event fix
f53af5295
Item Collect event will no longer be fired for items such as timeout items when they are not actually able to be collected. Due to timing changes, the "Combine when collected twice" now also occurs BEFORE the event.
- clear jit-compiled scripts as intended when loading new quest
ddf96eddd
- fix crash when creating too many paldatas
83a3bc867
- fix paldata->CopyCSet() referencing the wrong pointer
2a305c182
- handle out of bounds for Game->LItems[]
6d260c7f3
This fixes a crash in Panolpy when reading a specific sign.
- return enemy x,y when getting fairy item x,y
6e60fe889
Setting
item->X,Y
on fairy items additionally sets the position of the corresponding fairy enemy sprite. However, the getter returns the item coordinate. This resulted in unexpected behavior from something harmless likeitem->X = item->X
causing the engine fairy movement to halt. - fix sideview sprites becoming unable to jump when on the ground
673eb859d
- compat rule for old sprite jump behavior
2b7275305
Web
- use zc-data.nyc3.digitaloceanspaces.com for now
af524e98f
- "Copy URL" in player now uses correct test params
8b5eaf56d
- sync fs when writing save order txt file
e006c07a7
- quick save creation link working again
9e4c8a90f
The
quest
gamedata field was inadvertently set to 0 because the save file was prematurely selected before being saved for the first time, which prevented anything insaves_do_first_time_stuff
from sticking.
Documentation

Build
- fix missing libpng for web build
a6c345e5a
- fix missing libogg for web build
a5254efa0
- upgrade to latest asmjit
65ae72c6d
Resolves MSVC release mode bug: asmjit/asmjit#427
- add default file for compiler "signature"
26e8cd4db
This is to make the build just work in a clean checkout until I get around to removing this pointless thing altogether.
Refactors
- remove unused 'VSync' option (it didn't do anything)
74bbc05b7
- key files
d0864dc8d
Now work from the folder the quest is in OR the exe is in, and saves to the folder the quest is in. Also cleaned up the code for handling reading key files.
- remove unsupported color_depth option
f827b35bb
- load text files more efficiently
663e4dacf
- don't tint behind dropdown lists (allow skipping dlgs tint)
cb8f87135
- Menus (new sleeker look, much cleaner backend)
df3b5ab5b
- remove scary and now pointless warnings when toggling fullscreen
cf9942aca
Player
- remove unused volume code in read_saves
244b8cad0
- move x64 backend jit code to separate file
f3d40e0b7
- move global inits from init_game to new init_game_vars
c4f5c11ae
- make lamp_paid not static for replay determinism
534d82e91
- remove ZASM debugger from menu
377981e09
You may still activate this with
[CONSOLE] print_ZASM = 1
inzc.cfg
, but the option is no longer in the player menu. This will be removed entirely soon - it's so slow it can lock up a computer, and not useful enough to keep around.We may introduce a proper debugger in the future for ZScript to serve the purpose the ZASM debugger tried to.
- remove extra draws to scrollbuf in draw_screen
d57d0318b
- remove digi_music volume control
e426c5d1c
digi_music
is a global volume control for all allegro 4 music streams, which is only used for GME (so all those chiptune formats). But we already applyemusic_volume
(enhanced music) to all non-MIDI music, sodigi_music
was at best redundant, and at worse a confusing knob that only modified some music formats.It's been removed from the Sound dialog, and now defaults to 255 (100%). It can still be modified via scripts, though this should be changed to just set/read
emusic_volume
sometime in the near future.BTW - ~6 months ago OGG was changed to use Allegro 5 instead of 4, which means at that point
digi_music
no longer had any effect on OGG volume. - remove music buffer setting
9a6ae020b
This only applied to it/xm/s3m/mod music. There's no need to expose this to users. Instead, always use 128KB as a buffer size.

1084e5c54
This is the first of more planned script replay tests, which along with the playground.qst replays will be re-compiled with the latest zscript in CI and their replays re-verified. Should result in better test coverage for newer compiler features.

403c19750
To enable scripts to work in 2.55 and in a future release with z3 scrolling, we are adding a non-functional
Region
:Region->Width
: width in pixels (today, always 256)Region->Height
: height in pixels (176)Region->ScreenWidth
: width in screens (1)Region->ScreenHeight
: height in screens (1)Region->NumCombos
: number of combo positions (176)Region->ID
: region id (0 - meaning just a normal 1x1 area)Region->OriginScreen
: top-left screen in the regionRegion->GetScreenForComboPos(int pos)
: given a combo position, returns the screen index associated with itRegion->TriggerSecrets(int screen_index)
: trigger secrets for given screen. The screen must be in the region
For example, if a script uses
Region->NumCombos
instead of176
to iterate all the combos in the current area, it will work in both regions and non-regions. Additionally you should useComboAt(x, y)
rather than anything else to translate between pixel coordinates and a combo position. - mark combo->CSet deprecated, in favor for the better named ->CSet2
