2016-07-01SCI32: Use better audio fading algorithmColin Snover
Using the one from SCI2.1mid makes fades very slow because SDL has a larger audio buffer than SSCI DOS. This new algorithm is based on wall time so will always fade at the correct speed, although the larger buffers will have a coarser granularity so the fades may not be as smooth as in the original engine. If anyone cares, the fade volume could be mixed into individual samples in `readBuffer` instead of applying just once per complete buffer. SSCI did not do this, however, so this implementation should be pretty accurate.

SCI: Fixed KGetTime with SYSDATE subop in SCI0-LATE.
2016-06-30SCI32: Specify default hardware ratesColin Snover
This normally happens in SSCI when the audio hardware is initialised. CID 1357048
2016-06-30SCI32: Add transparent pic plane typeColin Snover
It is not clear if this is ever actually used by game scripts, though.
2016-06-30SCI32: Clean-up pass on rendering pipelineColin Snover
This pass exposed two bugs, which have been fixed: 1. Checks of `_updated` and `_moved` were reversed in some areas, which lead to rendering bugs. In SQ6 the rendering bugs were subtle or non-existant, but in e.g. PQ:SWAT the Sierra logo and title screen animations were totally missing. 2. The renderer formerly kept reading from ScreenItemLists when new items were added in decrementScreenItemArrayCounts, but this was determined to be unnecessary.
2016-06-30SCI32: Implement engine-accurate screen item list sortingColin Snover
It seems highly probable that there are later SCI games that use the "hi res" rendering path, so sorting and unsorting of ScreenItemLists needs to be accurate.
2016-06-30SCI32: Document & clean up extra rect argument for frameOutColin Snover
This extra rect seems to probably only ever be used by VMD playback in some SCI2.1 games.
2016-06-30SCI32: Add low resolution constantsColin Snover
In a few places in the graphics system, fixed low-resolution values are used instead of the game script resolution.
2016-06-27SCI: Add script patch for another Colonel's Bequest game bugMartin Kiewitz
Command input stays disabled, when oiling the arm of the armor. We fix this. This script bug also happens, when using the original interpreter. Fixes bug #7154
2016-06-27SCI: Fixed KGetTime with SYSDATE subop in SCI0-LATE.Omer Mor
SSCI implementation of the SYSDATE subop of the GetTime kernel function was changed between SCI0-LATE and SCI01: The base year used was changed from 1920 to 1980. This subop is used in "Codename: Iceman" (Say "ask for date" to a passing girl on the beach). The Atari ST version of "Codename: Iceman" use the 1980 base year. The Amiga version of "Codename: Iceman" appears to return the time instead of date, with 0 for the YEAR part.
2016-06-26SCI32: Fix benchmarking for QFG4Colin Snover
2016-06-26SCI32: Change Color::operator!= to all operator== directlyColin Snover
2016-06-26SCI32: Enable aspect ratio correction on QFG4CDColin Snover
2016-06-26SCI32: Fix typoColin Snover
2016-06-26SCI32: Remove no-longer-relevant commentColin Snover
2016-06-26SCI32: Add more workarounds for SCI2.1early gamesColin Snover
These games all share the same bad system script that always sends NULL as a second argument to kDoSound(play).
2016-06-26SCI32: Fix broken Remap implementationColin Snover
Remap would crash SCI2.1early games with 19 remap slots, and did not actually work in most cases in SCI2.1mid+ games. The SCI16 implementation was moved to its own separate file but was otherwise touched as little as possible, so may still have similar problems to the SCI32 code. 1. Split SCI16 and SCI32 code into separate files 2. Use -32 prefixes for SCI32 code and no prefix for SCI16 code, where possible, to match other existing code 3. Avoid accidental corruption of values from the VM that may be valid when signed or larger than 8 bits 4. Added documentation 5. Add missing remap CelObj calls 6. Inline where possible in performance-critical code paths 7. Fix bad `matchColor` function, and move it from GfxPalette to GfxRemap32 since it is only used by GfxRemap32 8. Fix bad capitalisation in getCycleMap 9. Remove unnecessary initialisation of SingleRemaps 10. Update architecture to more closely mirror how SSCI worked 11. Clarify the purpose of each type of remap type (and associated variable names) 12. Split large `apply` function into smaller units 13. Fix buffer overrun when loading a SCI2.1early game with remap 14. Remove use of `#define` constants 15. Warn instead of crashing with an error on invalid input (to match SSCI more closely) 16. Change the collision avoidance mechanism between the RemapType enum and remap kernel functions 17. Add save/load function
2016-06-26SCI32: Fix hang when playing auto-play audio channelsColin Snover
2016-06-26SCI32: Fix race condition when freeing audio resourcesColin Snover
It's not possible to call any ResourceManager methods from any thread other than the main thread because it is not thread-safe.
2016-06-25SCI: Add getGameObjectName to fix compilationMartin Kiewitz
Is needed for 80462b3 (Fix auto-saving in the fan-made Cascade Quest)
2016-06-25SCI: Fix auto-saving in the fan-made Cascade QuestMartin Kiewitz
Script patch to change the fixed slot 999 to fixed slot 99 in the game scripts and additional code for kSaveGame, that checks for Cascade Quest + slot 99 and will then use ScummVM slot 0, which is our auto-save slot. Fixes bug #7007 Also added the game name to the other fan-made script patch.
2016-06-25SCI32: Properly initialize pausedAtTick inside Audio32::play()Filippos Karapetis
Fixes audio not playing in later SCI32 games that use Audio32
2016-06-25Revert "SCI32: Properly initialize AudioChannel inside Audio32::play()"Filippos Karapetis
This reverts commit 5eaea05a2b6af0ddcf28fca1f0cd3fc0c54f4d07.
2016-06-25SCI: Script patch for critical Colonel's Bequest game bugMartin Kiewitz
This patch is about an issue, when interacting with the armor in room 37 (main house, downstairs). This bug also happened, when using the original interpreter and effectively froze the game depending on the coordinate of Laura Bow, when the command was entered. Fixes bug #7119 Versions affected: English PC/Atari ST/Amiga Floppy
2016-06-25SCI: Fix SQ1VGA script patch, fixes bug #7145Martin Kiewitz
Script patch used "lsg" for one instruction, which should have been "lag" instead. Caused issues with the spider droid. Added more details about this script patch in comments. Also specified the method for a qfg3 script patch in comments.
2016-06-23SCI32: Properly initialize AudioChannel inside Audio32::play()Filippos Karapetis
Fixes audio issues caused by uninitialized variables
2016-06-23SCI32: Fix usage of the C++11 override keyword with MSVCFilippos Karapetis
MSVC does not allow the usage of the "override" keyword on function definition, only on declaration
2016-06-23SCI32: Fix potentially uninitialized variableFilippos Karapetis
2016-06-23SCI32: Const correction in Audio32's readBuffer() implementationFilippos Karapetis
2016-06-22SCI: Assert on seeks past the end of audio resource bundlesColin Snover
This should never be allowed to happen, but currently does on multi-CD games with different resource bundles on difference CDs (Phant1, PQ:SWAT, GK2) because the resource manager does not yet have the ability to handle this situation.
2016-06-21SCI32: Implement kBitmapDrawViewColin Snover
2016-06-21SCI32: Expose a draw buffer on BitmapResource objectsColin Snover
Most of the time, we get a bitmap to draw on it. Exposing a buffer avoids consumers having to create their own all the time, and encourages use of common drawing code exposed by the buffer.
2016-06-21SCI32: Remove unused dependencies from GfxFrameoutColin Snover
2016-06-21SCI: Add an explanation about LRU removals when fetching resourcesColin Snover
Several times I have run into this code and had to take a minute to remind myself that the call to remove from the LRU on find is not wrong, so it seemed to deserve a comment.
2016-06-21SCI32: Fixes to GfxText32Colin Snover
1. Inline borderSize constant in createFontBitmap for consistency 2. Fix "DrawTextBox GetLongest=0" warning to only appear in games that actually had this check (SQ6 and MGDX) 3. "Fix" implementation of getTextSize for SCI2.1early, which gave lines with word wrap disabled a height of 0 4. Add inlining hints to some methods in BitmapResource that were missing them for some reason
2016-06-21SCI32: Implement basic kMessageBoxColin Snover
This kernel call seems only to be used by KQ7 1.51 (which was Windows-only) to send warnings to the user. It was easy enough to do a basic implementation in the ScummVM GUI rather than just make it an empty call, so now it is a thing.
2016-06-21SCI32: Add workaround for kScrollWindowAdd call in PhantasmagoriaWillem Jan Palenstijn
2016-06-21SCI32: Implement kScrollWindowWillem Jan Palenstijn
These should be all the actually used subfunctions. Co-authored-by: Colin Snover <github.com@zetafleet.com>
2016-06-21SCI32: Implement line drawing (kAddLine/kUpdateLine/kRemoveLine)Colin Snover
This line drawing code lives in a remodelled GfxPaint32 class that is totally separate from GfxPaint16.
2016-06-21SCI32: Make GfxText32::_scaledWidth/Height staticsWillem Jan Palenstijn
They were global in SSCI. This way secondary GfxText32 instances (such as in ScrollWindow) use the correct scaling.
2016-06-21SCI32: Fix drawText on consecutive control codesWillem Jan Palenstijn
2016-06-21SCI32: Fix getTextWidth on consecutive control codesWillem Jan Palenstijn
2016-06-21SCI32: Add low-pass filter to 8-bit SOL audioColin Snover
This improves the perceived quality of audio in games that use 8-bit samples for music, like Torin.
2016-06-20SCI32: Add kDoSound(play) workaround for LSL6hiresColin Snover
2016-06-20SCI: Minor cleanup of kDoSoundColin Snover
Replaces unused kernel calls to use kEmpty, and set correct signatures for SCI32 kernel calls.
2016-06-20SCI32: Rewrite digital audio engineColin Snover
This provides a complete implementation of kDoAudio through SCI2.1mid, plus partial implementation of SCI3 features. Digital audio calls shunted through kDoSound have also been updated to go through the SCI32 audio mixer, though these shunts are a bit hacky because the ScummVM implementation of kDoSound does not currently match how SSCI kDoSound is designed. It is probably possible in the future to just replace the SCI1.1 audio code (audio.cpp) with the new SCI32 code, since the major differences seem to be that (1) SCI1.1 only supported one digital audio playback channel (this is configurable already), (2) it had extra commands for CD audio playback and queued sample playback.
2016-06-19SCI: Split audio sync to its own classColin Snover
SCI32 has its own audio handling code, but audio sync code is the same as SCI16.
