Detailed Description

This is the namespace of the SCUMM engine.

Status of this engine: Complete support for all SCUMM based LucasArts adventures. Complete support for many Humongous Entertainment games, but for some of the newer ones, this is still work in progress.

Games using this engine:

  • Classic 2D LucasArts adventures
  • numerous Humongous Entertainment games

Enumeration Type Documentation

◆ GameFeatures

enum Scumm::GameFeatures

SCUMM feature flags define for every game which specific set of engine features are used by that game. Note that some of them could be replaced by checks for the SCUMM version.

Enumerator
GF_DEMO 

A demo, not a full blown game.

GF_NEW_COSTUMES 

Games with the AKOS costume system (ScummEngine_v7 and subclasses, HE games).

GF_USE_KEY 

Games using XOR encrypted data files.

GF_SMALL_HEADER 

Small header games (ScummEngine_v4 and subclasses).

GF_OLD_BUNDLE 

Old bundle games (ScummEngine_v3old and subclasses).

GF_16COLOR 

EGA games.

GF_OLD256 

VGA versions of V3 games. Equivalent to (version == 3 && not GF_16COLOR)

GF_AUDIOTRACKS 

Games which have Audio CD tracks.

GF_FEW_LOCALS 

Games using only very few local variables in scripts. Apparently that is only the case for 256 color version of Indy3.

GF_HE_LOCALIZED 

HE games for which localized versions exist

GF_HE_985 

HE games with more global scripts and different sprite handling i.e. read it as HE version 9.85. Used for HE98 only.

GF_16BIT_COLOR 

HE games with 16 bit color

GF_MAC_CONTAINER 

SCUMM v5-v7 Mac games stored in a container file Used to differentiate between m68k and PPC versions of Indy4

GF_HE_NO_BIDI 

SCUMM HE Official Hebrew translations were audio only but used reversed string for credits etc. Used to disable BiDi in those games.

GF_ULTIMATE_TALKIE 

The "Ultimate Talkie" versions of Monkey Island, which have been patched so that most workarounds/bugfixes no longer apply to them.

GF_HE_995 

HE99 games which were ported to a C++ codebase with HE99 opcodes and several HE100 GFX/Wiz features.

◆ anonymous enum

anonymous enum

Camera modes

◆ VirtScreenNumber

enum Scumm::VirtScreenNumber

Virtual screen identifiers

◆ ResTypeMode

enum Scumm::ResTypeMode

The mode of a resource type indicates whether the resource can be restored from the game data files or not. This affects for example whether the resource is stored in savestates.

Note that we treat sound resources somewhat differently: On the one hand, these behave mostly like a kStaticResTypeMode res type. However, when we create a savestate, we do save some information about them: Namely, which sound resources are loaded in memory at the time the save is made. And when loading, we invoke ensureResourceLoaded() for each sound resource that was marked in this way.

Enumerator
kDynamicResTypeMode 

Resource is generated during runtime and may change.

kStaticResTypeMode 

Resource comes from data files, does not change.

kSoundResTypeMode 

Resource comes from data files, but may change.

◆ anonymous enum

anonymous enum

The number of script slots, which determines the maximal number of concurrently running scripts, and the number of local variables in a script. WARNING: Do NOT changes these values unless you really have to, as this will break savegame compatibility if done carelessly. If you have to change them, make sure you update saveload.cpp accordingly!

◆ anonymous enum

anonymous enum
Enumerator
kMaxCutsceneNum 

The maximal number of cutscenes that can be active in parallel (i.e. nested).

kMaxScriptNesting 

The maximal 'nesting' level for scripts.

◆ anonymous enum

anonymous enum
Enumerator
LIGHTMODE_actor_use_base_palette 

Lighting flag that indicates whether the normal palette, or the 'dark' palette shall be used to draw actors. Apparently only used in very old games (so far only NESCostumeRenderer checks it).

LIGHTMODE_room_lights_on 

Lighting flag that indicates whether the room is currently lit. Normally always on. Used for rooms in which the light can be switched "off".

LIGHTMODE_flashlight_on 

Lighting flag that indicates whether a flashlight like device is active. Used in Loom (flashlight follows the actor) and Indy 3 (flashlight follows the mouse). Only has any effect if the room lights are off.

LIGHTMODE_actor_use_colors 

Lighting flag that indicates whether actors are to be drawn with their own custom palette, or using a fixed 'dark' palette. This is the modern successor of LIGHTMODE_actor_use_base_palette. Note: It is tempting to 'merge' these two flags, but since flags can check their values, this is probably not a good idea.

◆ ResType

enum Scumm::ResType

A list of resource types. WARNING: Do not change the order of these, as the savegame format relies on it; any change made here will break savegame compatibility!

◆ ClickArea

enum Scumm::ClickArea

The area in which some click (or key press) occurred and which is passed to the input script.

Function Documentation

◆ makeCDDAStream()

Audio::SeekableAudioStream* Scumm::makeCDDAStream ( Common::SeekableReadStream *  stream,
DisposeAfterUse::Flag  disposeAfterUse 
)

Create a new SeekableAudioStream from the CDDA data in the given stream. Allows for seeking (which is why we require a SeekableReadStream).

Parameters
streamThe SeekableReadStream from which to read the CDDA data
disposeAfterUseWhether to delete the stream after use
Returns
a new SeekableAudioStream, or NULL, if an error occurred
