Since actors can be active in 3x3 grid around the player, we need to
first load all objects in a 5x5 grid around the player.
Split load and unloading in 2 phases. Add an mInactiveCells set into the
scene, which contains all cells inside the aforementioned 5x5 grid.
These cells contains only heightfields and non-animated physics objects.
Animated objects are tied to the scene graph, which doesn't exists yet
in these cells, so we skip them.
Fixes#5483
This only applies to "base game" spells.
When adding an AutoCalc spell with TES:CS its cost is computed and
stored inside game files. This stored cost was being used by OpenMW and
the actual cost was never recomputed at runtime whereas Morrowind.exe
discards the stored cost.
While this worked fine in vanilla, mods can update AutoCalc spell
effects without ever updating the stored cost.
The formula was mostly there already but there was a few differences,
namely a 1 second offset in duration.
Actor may reach destination before collision. Get next path point from active
packet pathfinder and use point tolerance to reduce distance.
Use maximum of last destination tolerance and DEFAULT_TOLERANCE because
there are 2 checks made for path completion. First checks whether actor is
close enough to the destination and second drop last path point when actor is
closer than DEFAULT_TOLERANCE.
To fix all possible situations when active message box overlaps with loading
screen progress.
The only used condition to center loading screen progress by height is
number of message boxes > 0. No need to pass it through interface.
LoadingScreen can check it inside setLabel function.
Actor's position can be determined in 3 ways:
1/ as a result of physics simulation
2/ after a script require a relative position change (SetPos, Move)
3/ absolutely set from games mechanics event (teleport) or script
(PositionCell)
In case 1/, RefData::mPosition is updated with the physics simulation result
In case 2/, when RefData::mPosition is updated, physics simulation is informed of the change and update accordingly
In case 3/, when RefData::mPosition is updated, the physics simulation state is reset
In all 3 cases, we don't need to check the RefData::mPosition to get a
correct behaviour.
