Pass by reference to const

Fixes #30431, regression from #30277.
|
|
Some small optimizations in core/math/geometry.h.
|
|
By combining all scalar factors we can get rid of a scalar * vector
multiplication and a square root operation, since the resulting formula
only uses the squared length.
|
|
For clarity, assign-to-release idiom for PoolVector::Read/Write
replaced with a function call.
Existing uses replaced (or removed if already handled by scope)
|
|
|
|
It's the recommended way to set those, and is more portable
(automatically prepends -D for GCC/Clang and /D for MSVC).
We still use CPPFLAGS for some pre-processor flags which are not
defines.

Godot core needs MD5/SHA256/AES/Base64 which used to be provided by
separate libraries.
Since we bundle mbedtls in most cases, and we can easily only include
the needed sources if we so desire, let's use it.
To simplify library changes in the future, and better isolate header
dependencies all functions have been wrapped around inside a class in
`core/math/crypto_base.h`.
If the mbedtls module is disabled, we only bundle the needed source
files independently of the `builtin_mbedtls` option.
If the module is enabled, the `builtin_mbedtls` option works as usual.
Also remove some unused headers from StreamPeerMbedTLS which were
causing build issues.

Remove unnecessary code and add some error explanations

AStar get_current_point enabled consideration
|
|
|
|
|
|
|
|
Added 2D functions to AStar
|
|
|
|
Fix the performance of remove_point of AStar
|
|
Validate parameters of randi_range()
|
|
|
|
Improved uniformity of RandomPCG::randf.
|
|
|
|
Improve the performance of remove_point because it doesn't have to search every neighbour of every node
|
|
Added move_toward functions for float, Vector2 and Vector3
|
|
|
|
|
|
Optimize Basis constructor for Axis Angle
|
|
Can be used via scripting as `Geometry.triangulate_delaunay_2d(points)`
The interface is the same as in `Triangulate` library, returning indices
into triangulated points.

Clipper 6.4.2 is used internally to perform polypaths clipping, as well
as inflating/deflating polypaths. The following methods were added:
```
Geometry.merge_polygons_2d(poly_a, poly_b) # union
Geometry.clip_polygons_2d(poly_a, poly_b) # difference
Geometry.intersect_polygons_2d(poly_a, poly_b) # intersection
Geometry.exclude_polygons_2d(poly_a, poly_b) # xor
Geometry.clip_polyline_with_polygon_2d(poly_a, poly_b)
Geometry.intersect_polyline_with_polygon_2d(poly_a, poly_b)
Geometry.offset_polygon_2d(polygon, delta) # inflate/deflate
Geometry.offset_polyline_2d(polyline, delta) # returns polygons
// This one helps to implement CSG-like behaviour:
Geometry.transform_points_2d(points, transform)
```
All the methods return an array of polygons/polylines. The resulting
polygons could possibly be holes which could be checked with
`Geometry.is_polygon_clockwise()` which was exposed to scripting as well.

Improve the performance of AStar

|
Small fixes to static analyzer bugs
|
|
In GDScript, rename "decimals" to "step_decimals". In C#, add "StepDecimals", but keep the old functionality in a method called "DecimalCount".
|
|
Add missing methods to Rect2i
|
|
|
|
|
|
Add FRUSTUM camera mode, allowing tilted frustums
|
|
This adds support for groups in the import system, which point to a single file.
Add property hint for saving files in file field
|
|
Made AudioFrame and Vector2 equivalent for casting.
Added ability to obtain the playback object from stream players.
Added ability to obtain effect instance from audio server.
|
|
It seems to stay compatible with formatting done by clang-format 6.0 and 7.0,
so contributors can keep using those versions for now (they will not undo those
changes).
|
|
Added functions to AStar for disable/enable points to effectivly create obstacles
|
|
Added method to retrieve a direction vector from one point to another
|
|
Added smoothstep built-in function
|
