Happy new year to the wonderful Godot community!
2018-09-12Make core/ includes absolute, remove subfolders from include pathRémi Verschelde
This allows more consistency in the manner we include core headers, where previously there would be a mix of absolute, relative and include path-dependent includes.

hasher, this was leading to some severe slowdown in scenarios -Fixes to some duplication scenarios for instanced scenes
2018-01-05Add missing copyright headers and fix formattingRémi Verschelde
Using `misc/scripts/fix_headers.py` on all Godot files. Some missing header guards were added, and the header inclusion order was fixed in the Bullet module.

2017-04-14Correct Variant::hash_compare()Hein-Pieter van Braam
There was a logic error in #7815 which made Variant.hash_compare() == Variant.hash_compare() always true. In an attempt to short-circuit the NaN check I made an (in hindsight) obvious error: 10 == 12 || is_nan(10) == is_nan(12) This will be true for all inputs, except for the NaN, not-NaN case. The macro has been updated to now generate: (10 == 12) || (is_nan(10) && is_nan(10)) so: (10 == 12) || (is_nan(10) && is_nan(12)) = false False or (False and False) is False (10 == 10) || (is_nan(10) && is_nan(10)) = true True or (False and False) is True (Nan == 10) || (is_nan(NaN) && is_nan(10)) = false False or (True and False) is False (Nan == Nan) || (is_nan(NaN) && is_nan(NaN)) = true False or (True and True) is True Which is correct for all cases. This bug was triggered because the hash function for floating point numbers can very easily generate collisions for the tested Vector3(). I've also added an extra hashing step to the float hash function to make this less likely to occur. This fixes #8081 and probably many more random weirdness.

2017-03-05A Whole New World (clang-format edition)Rémi Verschelde
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
2017-02-16Correct hash behavior for floating point numbersHein-Pieter van Braam
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.
2017-01-01Welcome in 2017, dear changelog reader!Rémi Verschelde
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer with state-of-the-art rendering techniques tuned to work as low as middle end handheld devices - without compromising with the possibilities given for higher end desktop games of course. Great times ahead for the Godot community and the gamers that will play our games!
2016-10-12Fixes hash float negative 0 problemRăzvan Cosmin Rădulescu
Before this was giving an error: var a = {Vector2(1, 0): 5, Vector2(-1, 0): 7} print(a) print(a[Vector2(1, 0)]) print(a[-Vector2(1, 0)]) This simple commit fixes the issue.

2014-05-14A bit of everything:Juan Linietsky
-IMA-ADPCM support for samples, this means that sound effects can be compressed and use 4 timess less RAM. -New 3D import workflow based on Wavefront OBJ. Import single objects as mesh resources instead of full scenes. Many people prefers to work this way. Just like the rest of the imported resources, these are updated in realtime if modified externally. -Mesh resources now support naming surfaces. This helps reimporting to identify which user-created materials must be kept. -Several fixes and improvements to SurfaceTool. -Anti Aliasing added to WorldEnvironment effects (using FXAA) -2D Physics bodies (RigidBody, KinematicBody, etc), Raycasts, Tilemap, etc support collision layers. This makes easy to group which objects collide against which. -2D Trigger shapes can now also trigger collision reporting in other 2D bodies (it used to be in Area2D before) -Viewport render target textures can now be filtered. -Few fixes in GDscript make it easier to work with static functions and class members. -Several and many bugfixes.
