This version of the commit has the on_ceiling/on_wall fix without any
explaination of that code, since apparently it wasn't complicated enough.
As for the notes at the top of the function, they're still there.
move_and_slide is rather useful for character-controllers, etc.
It reduces the amount of boilerplate code.
Not having move_and_slide makes the APIs somewhat inconsistent.
(It might be nice to figure out a way to share the code between the two
move_and_slide implementations, but that's for someone who knows what
the policy is on shared code like that.)
Represent a raycast by a line segment using the direction and magnitude of the cast_to vector.
The entire line segment will become red while a collision occurs.
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
-An action being requested to the user in present tense: (ie, draw, gui_input, etc)
-A notification that an action happened, in past tense (ie, area_entered, modal_closed, etc).
- C++ Nodes mostly do an internal process callback, so it does not conflict with users willing to use their own process callbacks
- callbacks such as _input, _process, _fixed_process _unhandled_input, _unhandled_key_input do not requiere calling a function to enable them. They are enabled automatically if found on the script.
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).
