In contrast to the comment in o_beginOverride() VAR(VAR_OVERRIDE) is not set in the disassembly. In addition the cutscene stack-pointer is always 0 as this feature is not used in v0. This makes o_beginOverride() work the same way o2_beginOverride() and so it is not needed anymore.
Note that fetchScriptWord() was changed to ScummEngine::fetchScriptWord() in o2_beginOverride() as ScummEngine_v0::fetchScriptWord() only fetches a byte.
As we need two bytes here we have to use ScummEngine::fetchScriptWord().
The comparison "ABS((int)(deltaXFactor >> 16)) > _speedx)" does not work as "deltaXFactor >> 16" will clear the fractional part of deltaXFactor. As a result the deltaXFactor might be bigger than (_speedx<<16) and the actor moves faster than he should.
Before, the actor will descend the ladder of the pool and maybe even into the the pool. Another issue fixed by this is the actor climbing onto the plant pot if you give something to it.
command in v0
If for instance an object necessary for the sentence command is not reachable or pickupable (try to use faucet (object 55) with jar with water in microwave (object 50), the pick-up script of the jar will tell the actor to pickup object 99 (jar not in microwave)) the actor will try to pick-up the jar infinitely.
This is fixed by counting the amount of nested scripts the sentence command has called (directly or indirectly) so far and aborts it if there have been too many.
Some object functions allow actor IDs and object IDs as parameters. They are easily distinguishable in engines > 0 as actor IDs are < _numActors and object IDs are bigger. In v0 this is not the case as there are objects with IDs like 3 and 5 (e.g. the hamster). So object ID handling was unified for v0 and the other engines by introducing objIsActor(), objToActor() and ActorToObj().
It actually was stopMusic() before and so stopped only the music and not all sounds.
The former implementation is for the o_stopMusic opcode which is not supported directly by ScummVM (it always stops all sounds). It is kept as stopMusic_intern() but is not used anymore.
- handle mode switching correctly
- do not freeze scripts in cutscene mode (mode 0), as some scripts are freezed in mode 0 that should not be freezed
- kModeNoNewKid (mode 2) needs the same userState as mode 3
- rename o_cursorCommand to o_setMode as it is not really cursor specific
- handle actorHiding correctly (do not set costume to 0 as the previous costume cannot be reverted after hiding)
- add drawSentence
- document meanings for actor misc flags
- fix actor names for "new kid" if the radiation suit is used (all kids are set to 0 then with actor 0 name " ")
- cleanup actor switching routine
- _userPut is not used anymore in v0
- o_setObjectName has a default value
- o_putActorAtObject can either operate on a fg or bg object
Note: neither the default value nor the bg object opcode (4E) seem to be ever used by any script. So this commit is rather for completeness than for bug-fixing.
