…mages I'm baffled how I did not notice this behavior earlier, but engine was created at least 2 redundant intermediate bitmaps meant to cache transformed sprites per each object and character on screen for HW-accelerated renderers, - which they do not need, as they don't use software transformations. The resulting effect won't be too notable for low-res games with low amount of simultaneous objects, but may be quite significant for the high-res games with multiple large objects in the room. From upstream cca997fe83ec5f7014677a69095a7c9ec1494cd9
This somewhat reverts 2b9f130 , while keeping tidier code and safer args. Switching from lzwexpand_to_mem to using streams only caused speed regression, which became notable for hi-res games with LZW sprite compression (a 3.6.0 feature). For this revert we instead load compressed data into a buffer in whole, then pass two memory buffer pointers to lzw_expand, where it reads and writes memory directly. Testing a high-res (1920x1080) game with lots of sprite streaming showed speed improvement of this function by around 200%. The downside is the temporary buffer for reading compressed data too. In theory, same could be done for lzwcompress afterwards. From upstream 6959004676916568c6fca210702d669f61741e13
The example when this could happen:
Parser.Said("climb,get in bed");
where "climb", "get" and "bed" are dictionary words.

…render In ALSoftwareGraphicsDriver: * Save index of a currently rendered sprite batch (or none, if not inside a render pass). * In SetMemoryBackBuffer() don't reset virtual screen subbitmaps unless we are outside render pass. * In InitSpriteBatch() also test if batch's surface is subbitmap to the current virtual screen (in case one was replaced, but batch's surface stayed). Partially from upstream 5dd078961020da6478347dac01dea729471333d1
…ole VS When plugin calls SetVirtualScreen (for software renderer), don't replace whole virtual screen, instead replace only the current render stage buffer. This is complementary to the older changes in software renderer, made during development of AGS 3.5.0, which featured advanced room viewports and cameras. Since that change, separate render stages could draw on sub-bitmaps of smaller size. While IAGSEngine::GetVirtualScreen() was adjusted to follow that change, and return not the whole virtual screen, but only a "stage buffer" (which may be a VS sub-bitmap, or an intermediate bitmap created specifically for this render stage), SetVirtualScreen() was NOT adjusted accordingly and kept replacing whole VS. As a result, this discrepancy could cause logical errors, as well as crashes with plugins that use this API (e.g. original SnowRain plugin). The immediate reason of error is that plugin would remember a pointer returned from GetVirtualScreen (which is a stage buffer), and then try to set it back with SetVirtualScreen. As a result, engine's own stage buffer is assigned as a full virtual screen. From upstream 09143ea7fbf8474f78932116ae1c81ceff4de95a

…formats This allows to properly fixup (upgrade) RoomStatus structs restored from a older format save in an upgraded game. For example: game was upgraded from 3.4.0 to 3.6.0, but player tries loading 3.4.0 save. In this situation the engine must know and keep track of what version each RoomStatus was saved in. This is necessary, because RoomStatus can only be updated upon loading a corresponding room file (when entering a room). This means that multiple RoomStatus objects will be staying in memory not being upgraded yet, until player enters particular room. From upstream 205232af5909e0a257494ff404f36003b004ebc4
From upstream b8de51fedf0318e8243e1fc3872c61f366a23144
NOTE: the code theoretically allows any object to be sorted this way, but the problem is, the ID sequences are not shared, and multiple object types may have same IDs. This is something to consider in the future.

@tag2015 : Thanks for doing this. I was looking at it, but it is quite a task to review through the upstream commits and integrate, so kudos. @criezy : Once this is integrated, we will need to review the open AGS bugs to see which are still present and which are fixed by the upstream patches. If you want help with that, let me know. |
Well, I can comment in advance on some of the bugs, from what I have tested, as I have most of the games (including the commercial ones except lancelot's hangover): |
|
Incredible work. Thank you for keeping it up to date. |
|
@tag2015 : Thanks for confirming those. I suspected we can probably close a fair few after confirming the fix... and I suspected that my current "favourite" bug i.e. Hob's Barrow at https://bugs.scummvm.org/ticket/14072 would still be broken. I think that is an issue in the allegro interface code so different to upstream. It may be present upstream, but a latent issue. However, still haven't got to the bottom of why that happens. Any help gratefully received. |
|
@criezy : Do you have time to review this soon or are you happy as-is? Just that we have a bunch of AGS bugs which could probably get closed once this is merged :) |
Yes, I have some time, but there are a lot of commits to review, so it will take a few more days |
|
@criezy : No problem. I did suspect you were doing it, but just wanting to try to stop users reporting bugs which upstream have fixed ... and allow me to finish my backlog of AGS games in my game library cough :) One note, this PR is now in the "This branch cannot be rebased due to too many changes" state. It will likely need you to merge it manually locally as I think the Github UI can't cope with the master changes which may overlap :| |
|
Great job. |
This PR brings ScummVM's AGS implementation up to date with version 3.6.41,
It includes fixes for priority errors reported in Kathy Rain, Blackwell Convergence,
Resonance, Kill Yourself and probably others.
