RigidDynamicBody modes are replaced with several properties to make their
usage clearer:
-lock_rotation: disable body's rotation (instead of MODE_LOCKED)
-freeze: no gravity or forces (instead of MODE_STATIC and MODE_KINEMATIC)
-freeze_mode: Static (can be only teleported) or Kinematic (can be animated)
Also renamed MODE_DYNAMIC_LOCKED to MODE_DYNAMIC_LINEAR in the physics
servers.
Move multiplayer classes to "core/multiplayer" subdir.
Move the RPCConfig and enums (TransferMode, RPCMode) to a separate
file (multiplayer.h), and bind them to the global namespace.
Move the RPC handling code to its own class (RPCManager).
Renames "get_rpc_sender_id" to "get_remote_sender_id".
Segment collision results could be different depending on the direction
when they exactly touch (order of the points in segments). This was due
to the way parallelism was checked, using different logic based on
positive or negative sign of cross products.
Now the results are the same whatever the direction, without changing
the current design, which is that parallel or colinear segments are
not considered colinear.
Fixes inconsistencies with raycasts exactly on edges of convex shapes
depending on the direction.
The new tests cover:
- A file with empty extension.
- A file with only extension (a "hidden" file, unix style).
- A file directly at the windows top level directory.
- A file directly at the unix root directory.
- A file directly at the res:// base directory.
While calculating interpolated points, intervals between two baked
points has been assummed to be `baked_interval`. The assumption could
cause significant error in some extreme cases (for example #7088).
To improve accuracy, `baked_dist_cache` is introduced, which stores
distance from starting point for each baked points. `interpolate_baked`
now returns exact linear-interpolated position along baked points.
Fixes undefined behavior, and fixes the logic for negative powers of ten.
Fixes#51764.
Adds tests to validate the changes and prevent regressions.
Adds docs for `String.num`.
Adds a few more complex edge cases which are supported.
Also adds some documentation, simplifies the code a bit and forbids using
double quotes as a delimiter.
