Cylinder collision shape should give the best consistency between physics
simulation and pathfinding. Rotating box is already used by some actors, so
add it to have the same collision shape type for all actors.
Actors with disabled collisions still have physics simulations. Assuming they
should not be processed at all instead of disabling collision add a new flag to
make them inactive.
Actor::getOnGround and Actor::getOnSlope is used to initialize ActorFrameData.
After a physics simulation the result is copied back. But when actor is outside
processing range, Actor::mInternalCollisionMode is false and physics simulation
does not recalculate OnGround and OnSlope flags. So the flags are always set to
false that makes actor play landing animation when they exit and then enter
actors processing range.
Engine controls lifetime of managers therefore it should own them. Environment
is only access provider.
This allows to avoid redundant virtual calls and also some functions from
managers base classes can be removed if they are used only by Engine.
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/
Currently, we use an `UnrefQueue` which supposedly aims to transfer destruction costs to another thread. The implications of this unusual pattern can not be well understood because some allocators might free resources more efficiently if they are freed by the same thread that allocated them. In addition, `UnrefQueue` complicates the validation of thread safety in our engine. Lastly, our current usage of `UnrefQueue` triggers `ref()`, `unref()` atomic operations as objects are passed into the queue. These operations could be more expensive than the actual destruction.
With this PR we thus remove `UnrefQueue`. We can expect these changes to have a minor impact at most because we free most resources elsewhere in `ResourceSystem::updateCache`.
To reduce amount of computations on the caller side and restrict possible
values.
* verts can't be non-int because it's a number of things.
* worldsize is initially defined as int by ESM::Land::REAL_SIZE.
* Put function to calculate heightfied shift into components to be able to
reuse by other binaries.
Use faster aabbTest but without destance filter. To avoid dependency on a
specific constant and correctly handle situations when there is a big
difference between actors sizes.
