Use std::variant. Store refId strings in unordered_set and use pointer to an
item there. Inserts to unordered_set do not invalidate pointers to values so the
pointer is always valid. Elements are not removed. Assume there is finite number
of string refIds.
Skipping the simulation, switching off collisions, and other approaches were not correct as they either broke some mods, or some core mechanics of the engine such as teleportation or waterwalking. As it turns out, the way to go is to simply do _nothing_ (modulo some gymnastics to account for the 1 frame difference in case of async).
Scripted movement and the unstucking logic tends to collide. Early out of unstuck in case the actor doesn't attempt to move. This means there is no AI package for NPC, which are the case for some boats and striders, or the player is content with their position.
Fixed some types
removed useless header
applied clang format
fixed compile tests
fixed clang tidy, and closer to logic before this MR
Removed hardcoded refids
unless there is a returned value we don't use static RefIds
can use == between RefId and hardcoded string
Fix clang format
Fixed a few instances where std::string was used, when only const std::string& was needed
removed unused variable
The strong type is actually just a string underneath, but this will help in the future to have a distinction so it's easier to search and replace when we use an integer ID
Slowly going through all the changes to make, still hundreds of errors
a lot of functions/structures use std::string or stringview to designate an ID. So it takes time
Continues slowly replacing ids. There are technically more and more compilation errors
I have good hope that there is a point where the amount of errors will dramatically go down as all the main functions use the ESM::RefId type
Continue moving forward, changes to the stores
slowly moving along
Starting to see the fruit of those changes.
still many many error, but more and more Irun into a situation where a function is sandwiched between two functions that use the RefId type.
More replacements. Things are starting to get easier
I can see more and more often the issue is that the function is awaiting a RefId, but is given a string
there is less need to go down functions and to fix a long list of them.
Still moving forward, and for the first time error count is going down!
Good pace, not sure about topics though, mId and mName are actually the same thing and are used interchangeably
Cells are back to using string for the name, haven't fixed everything yet. Many other changes
Under the bar of 400 compilation errors.
more good progress <100 compile errors!
More progress
Game settings store can use string for find, it was a bit absurd how every use of it required to create refId from string
some more progress on other fronts
Mostly game settings clean
one error opened a lot of other errors. Down to 18, but more will prbably appear
only link errors left??
Fixed link errors
OpenMW compiles, and launches, with some issues, but still!
The virtual function does the same thing.
* Change return type to osg::Vec2i to avoid dependency on ESM3.
* Rename to positionToCellIndex to make it clear what is the index.
Previous version skipped collision the frame immediately after a call to SetPos. It worked for one-off calls (teleports for instance) and continuous call along a pre-defined path (scenic travel). However, in the case of mod which uses SetPos to simulate a player-controlled movement, it is equivalent to using tcl.
Solution:
1/ skip update of mPosition and mPreviousPosition to avoid janky interpolation
2/ use back plain moveObject() instead of moveObjectBy() since we don't want physics simulation
3/ rework a little bit waterwalking influence on coordinate because of 1/
Instead of registering the desired change of position and rely on
physics simulation to apply it to the world, immediately change the
position in the world without reset the simulation.
When a script calls SetPos for x,y,z in sequence on an actor, we need to make sure
that the actor will not spawn under ground at x,y coordinates.
Now that change of coordinates are cumulated and applied all at once, we
need to account for the whole offset.
To this end move the terrain height check inside of Actor class.
its current position.
Use it in relevant MWScripts opcode (move and moveworld).
Remove the fragile detection of scripted translation from PhysicsTaskScheduler.
No user visible change, just a more robust mechanism.
Before this change, if an actor position was changed while the physics
simulation was running, the simulation result would be discarded. It is
fine in case of one off event such as teleport, but in the case of
scripts making use of this functionality to make lifts or conveyor (such
as Sotha Sil Expanded mod) it broke actor movement.
To alleviate this issue, at the end of the simulation, the position of the Actor
in the world is compared to the position it had at the beginning of the
simulation. A difference indicate a force move occured. In this case,
the Actor mPosition and mPreviousPosition are translated by the difference of position.
Since the Actor position will be really set while the next simulation runs, we
save it in the mNextPosition field.
setPosition(getPosition() + diff) to move actor in scripts.
With background physics, this is very slightly off with the collision
object position.
When the script run long enough (a few dozen frames for instance),
the accumulated error becomes too big. It make actors fall through lifts floors.
