Ferenc Arn e4eb093c62 Avoid overestimating the cost in AStar heuristics.
This is a necessary condition for finding optimal solutions.
This is achieved by simply requiring/ensuring that no weights are smaller than 1.

Fixes #8584.

Ferenc Arn ceb699f5ec Fix PRNG randomization.
PCG32 doesn't like small seeds, which leads to zero random values (prior to #7532, zero values were handled as special cases).

Use a large default seed, and also add a shift in Math::randomize.

Fixes #8423.

Various other changes mostly cosmetic in nature.

Ferenc Arn 1a620bd5fa Made slide and reflect active verbs acting on itself in Vector2 and Vector3.
This is in alignment with other functions in vector classes.
Also added checks for normalization, fixed the sign of reflect (which now corresponds to reflection along a plane mathematically), added bounce method and updated docs.

Fixes #8201.

Ferenc Arn 97d510531a Fix polar decomposition in 2D.
When performing polar decomposition in 2D as B = R.S, where R is rotation (with determinant +1) and S is scaling, use the convention that reflections are absorbed into S through a reflection around y axis.
In 3D, this is done by using a reflection along all three axes, but since the dimensionality is even in 2D, one axis needs to be chosen.

Fixes Matrix32::get_rotation and Matrix32::get_scale (which weren't properly fixed in #7445).

Rémi Verschelde 5dbf1809c6 A Whole New World (clang-format edition)
I can show you the code
Pretty, with proper whitespace
Tell me, coder, now when did
You last write readable code?

I can open your eyes
Make you see your bad indent
Force you to respect the style
The core devs agreed upon

A whole new world
A new fantastic code format
A de facto standard
With some sugar
Enforced with clang-format

A whole new world
A dazzling style we all dreamed of
And when we read it through
It's crystal clear
That now we're in a whole new world of code

Hein-Pieter van Braam b696beea65 Correct hash behavior for floating point numbers
This fixes HashMap where a key or part of a key is a floating point
number. To fix this the following has been done:

* HashMap now takes an extra template argument Comparator. This class
gets used to compare keys. The default Comperator now works correctly
for common types and floating point numbets.

* Variant implements ::hash_compare() now. This function implements
nan-safe comparison for all types with components that contain floating
point numbers.

* Variant now has a VariantComparator which uses Variant::hash_compare()
safely compare floating point components of variant's types.

* The hash functions for floating point numbers will now normalize NaN
values so that all floating point numbers that are NaN hash to the same
value.

C++ module writers that want to use HashMap internally in their modules
can now also safeguard against this crash by defining their on
Comperator class that safely compares their types.

GDScript users, or writers of modules that don't use HashMap internally
in their modules don't need to do anything.

This fixes #7354 and fixes #6947.

Juan Linietsky 04a6d2789e Revert "Make nan==nan true for GDScript" 2017-02-14 17:05:16 -03:00
Hein-Pieter van Braam adcc211feb Make nan==nan true for GDScript
After discussing this with Reduz this seemed like the best way to
fix #7354. This will make composite values that contain NaN in the same
places as well as the same other values compare as the same.

Additionally non-composite values now also compare equal if they are
both NaN. This breaks IEEE specifications but this is probably what most
users expect. There is a GDScript function check for NaN if the user
needs this information.

This fixes #7354 and probably also fixes #6947

the licensing with the original author (public domain).

Ferenc Arn f271591ac2 Various corrections in 2D math.
This is the follow up for the 2D changes mentioned in PR #6865. It fixes various mistakes regarding the order of matrix indices, order of transformation operations, usage of atan2 function and ensures that the sense of rotation is compatible with a left-handed coordinate system with Y-axis pointing down (which flips the sense of rotations along the z-axis). Also replaced float with real_t, and tried to make use of Matrix32 methods rather than accessing its elements directly.

Affected code in the Godot code base is also fixed in this commit.

The user code using functions involving angles such as atan2, angle_to, get_rotation, set_rotation will need to be updated to conform with the new behavior. Furthermore, the sign of the rotation angles in existing 2D scene files need to be flipped as well.
