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.

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.

-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.
