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.
According to Issue #8018, a BIND_VMETHOD macro wasn't present in scene/gui/control.cpp, while it was declared to be a virtual method in scene/gui/control.h.
classes.xml was updated to also list this method in Control.
- Added `tab_selected` signal. Which emits a signal by selecting any tab, if current tab is selected again.
- Added `get_previous_tab()`. Which returns the previous shown tab. **Note:** only `tab_changed` can modify previous tab index.
- Add documentation for the added function and signals. Fix a typo too.
This is a part of the breaking changes proposed in PR #6865, solving the issue regarding the order of affine transformations described in #2565. This PR also fixes the affected code within Godot codebase. Includes improvements to documentation too.
Another change is, Matrix3::get_scale() will now return negative scaling when the determinant of the matrix is negative. The rationale behind this is simple: when performing a polar decomposition on a basis matrix M = R.S, we have to ensure that the determinant of R is +1, such that it is a proper rotation matrix (with no reflections) which can be represented by Euler angles or a quaternion.
Also replaced the few instances of float with real_t in Matrix3 and Transform.
Furthermore, this PR fixes an issue introduced due to the API breakage in #6865. Namely Matrix3::get_euler() now only works with proper rotation matrices. As a result, the code that wants to get the rotation portion of a transform needs to use Matrix3::get_rotation() introduced in this commit, which complements Matrix3::get_scaled(), providing both parts of the polar decomposition.
Finally, it is now possible to construct a rotation matrix from Euler angles using the new constructor Matrix3::Matrix3(const Vector3 &p_euler).
Furthermore, functions which expect a rotation matrix will now give an error simply, rather than trying to orthonormalize such matrices. The documentation for such functions has be updated accordingly.
This commit breaks code using 3D rotations, and is a part of the breaking changes in 2.1 -> 3.0 transition. The code affected within Godot code base is fixed in this commit.
* Added the option to set hide on item selection. Usable in GDScript and from within the source code when you want to specify popup menus you don't want to close immediately when selecting an item
* Renamed getter from get_ to is_, fixed parent/child behavior, renamed bool variable to match most code and added ADD_PROPERTYNO to save some memory
