2021-08-14New and improved IK system for Skeleton3DTwistedTwigleg
This PR and commit adds a new IK system for 3D with the Skeleton3D node that adds several new IK solvers, as well as additional changes and functionality for making bone manipulation in Godot easier. This work was sponsored by GSoC 2020 and TwistedTwigleg Full list of changes: * Adds a SkeletonModification3D resource * This resource is the base where all IK code is written and executed * Adds a SkeletonModificationStack3D resource * This node oversees the execution of the modifications and acts as a bridge of sorts for the modifications to the Skeleton3D node * Adds SkeletonModification3D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK * Each modification is in it's own file * Several changes to Skeletons, listed below: * Added local_pose_override, which acts just like global_pose_override but keeps bone-child relationships intract * So if you move a bone using local_pose_override, all of the bones that are children will also be moved. This is different than global_pose_override, which only affects the individual bone * Internally bones keep track of their children. This removes the need of a processing list, makes it possible to update just a few select bones at a time, and makes it easier to traverse down the bone chain * Additional functions added for converting from world transform to global poses, global poses to local poses, and all the same changes but backwards (local to global, global to world). This makes it much easier to work with bone transforms without needing to think too much about how to convert them. * New signal added, bone_pose_changed, that can be used to tell if a specific bone changed its transform. Needed for BoneAttachment3D * Added functions for getting the forward position of a bone * BoneAttachment3D node refactored heavily * BoneAttachment3D node is now completely standalone in its functionality. * This makes the code easier and less interconnected, as well as allowing them to function properly without being direct children of Skeleton3D nodes * BoneAttachment3D now can be set either using the index or the bone name. * BoneAttachment3D nodes can now set the bone transform instead of just following it. This is disabled by default for compatibility * BoneAttachment3D now shows a warning when not configured correctly * Added rotate_to_align function in Basis * Added class reference documentation for all changes

2021-06-11Reformat structure string operatorsAaron Franke
The order of numbers is not changed except for Transform2D. All logic is done inside of their structures (and not in Variant). For the number of decimals printed, they now use String::num_real which works best with real_t, except for Color which is fixed at 4 decimals (this is a reliable number of float digits when converting from 16-bpc so it seems like a good choice)

2021-04-27Core: Drop custom `copymem`/`zeromem` definesRémi Verschelde
We've been using standard C library functions `memcpy`/`memset` for these since 2016 with 67f65f66391327b2967a20a89c3627e1dd6e84eb. There was still the possibility for third-party platform ports to override the definitions with a custom header, but this doesn't seem useful anymore.

2021-01-01Update copyright statements to 2021Rémi Verschelde
Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆
2020-12-07Improve argument names for core typesAaron Franke
2020-11-07Reorganized core/ directory, it was too fatty alreadyreduz
-Removed FuncRef, since Callable makes it obsolete -Removed int_types.h as its obsolete in c++11+ -Changed color names code
2020-09-23Remove redundant is_equal_approx_ratio methodAaron Franke
is_equal_approx is able to handle values of any size, and is_equal_approx_ratio is no longer used in any exposed APIs, so we don't need is_equal_approx_ratio anymore. Also, add #ifdef MATH_CHECKS for a method that is only used when MATH_CHECKS is defined.

2020-06-12- Added more euler rotation orders support.Andrea Catania
- Fixed floating point issue on the old one. - Fixed the equation on the get_euler_yxz function. - Added unit tests. This work has been kindly sponsored by IMVU.
2020-05-14Style: Enforce braces around if blocks and loopsRémi Verschelde
Using clang-tidy's `readability-braces-around-statements`. https://clang.llvm.org/extra/clang-tidy/checks/readability-braces-around-statements.html
2020-05-14Style: Enforce separation line between function definitionsRémi Verschelde
I couldn't find a tool that enforces it, so I went the manual route: ``` find -name "thirdparty" -prune \ -o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \ -o -name "*.glsl" > files perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files) misc/scripts/fix_style.sh -c ``` This adds a newline after all `}` on the first column, unless they are followed by `#` (typically `#endif`). This leads to having lots of places with two lines between function/class definitions, but clang-format then fixes it as we enforce max one line of separation. This doesn't fix potential occurrences of function definitions which are indented (e.g. for a helper class defined in a .cpp), but it's better than nothing. Also can't be made to run easily on CI/hooks so we'll have to be careful with new code. Part of #33027.
2020-05-14Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocksRémi Verschelde
Which means that reduz' beloved style which we all became used to will now be changed automatically to remove the first empty line. This makes us lean closer to 1TBS (the one true brace style) instead of hybridating it with some Allman-inspired spacing. There's still the case of braces around single-statement blocks that needs to be addressed (but clang-format can't help with that, but clang-tidy may if we agree about it). Part of #33027.
2020-05-10New lightmapperJuan Linietsky
-Added LocalVector (needed it) -Added stb_rect_pack (It's pretty cool, we could probably use it for other stuff too) -Fixes and changes all around the place -Added library for 128 bits fixed point (required for Delaunay3D)
2020-05-10Style: clang-format: Disable AllowShortIfStatementsOnASingleLineRémi Verschelde
Part of #33027, also discussed in #29848. Enforcing the use of brackets even on single line statements would be preferred, but `clang-format` doesn't have this functionality yet.

2020-01-01Update copyright statements to 2020Rémi Verschelde
Happy new year to the wonderful Godot community! We're starting a new decade with a well-established, non-profit, free and open source game engine, and tons of further improvements in the pipeline from hundreds of contributors. Godot will keep getting better, and we're looking forward to all the games that the community will keep developing and releasing with it.

2019-04-09Style: Apply new changes from clang-format 8.0Rémi Verschelde
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).

2019-02-09[Core] Rename Matrix3 file to BasisAaron Franke
The code already referred to "Basis", it's just the file name that was different for some reason.
