PhysicsBody now has methods move_and_collide/test_move and needed
properties for these methods: safe margin, locked axes (3D only).
Moved collision_exceptions from StaticBody to PhysicsBody for 3D
(same as 2D, and conforms to documentation).
RigidBody doesn't have test_motion method anymore, it's now redundant
with PhysicsBody.test_move.
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 🎆
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.
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.
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.
It's tedious work...
Some can't be ported as they depend on private or protected methods
of different classes, which is not supported by callable_mp (even if
it's a class inherited by the current one).
- Renames PackedIntArray to PackedInt32Array.
- Renames PackedFloatArray to PackedFloat32Array.
- Adds PackedInt64Array and PackedFloat64Array.
- Renames Variant::REAL to Variant::FLOAT for consistency.
Packed arrays are for storing large amount of data and creating stuff like
meshes, buffers. textures, etc. Forcing them to be 64 is a huge waste of
memory. That said, many users requested the ability to have 64 bits packed
arrays for their games, so this is just an optional added type.
For Variant, the float datatype is always 64 bits, and exposed as `float`.
We still have `real_t` which is the datatype that can change from 32 to 64
bits depending on a compile flag (not entirely working right now, but that's
the idea). It affects math related datatypes and code only.
Neither Variant nor PackedArray make use of real_t, which is only intended
for math precision, so the term is removed from there to keep only float.
When there is no collision with a floor the get_floor_normal() function
should return the zero vector to be consistent with get_floor_velocity().
Renames floor_normal to up_direction in all bindings.
Updates the documentation of get_floor_normal() and get_floor_velocity()
to make it clear when the values are valid. Updates the documentation for
move_and_slide() and move_and_slide_with_snap() to use the new up_direction
parameter name.
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.
In the 3D version:
- Partially revert #20908 that was reverted in the 2D version as part
of #21653. This ensures that the Vector returned is always perpendicular
to the surface collided with; and not the floor_normal Vector passed to
the function when on a floor.
- Include an update of the floor velocity before multiplying by the time
delta, which was added to the 2D version as part of commit 13a8014.
In the 2D version:
- Use the Vector2.slide() function instead of Vector2.tangent() to adjust
the amount of motion the stop_on_slope undoes to ensure that it is in the
right direction. This is a implementation of the 3D approach from #30588.
- Combine the !found_collision and motion == Vector2() checks for break.
- Other minor formating changes to make the functions look identical.
Also renamed some variables to align with their use.
When moving KinematicBody2D from one scene to another and not freeing
the old scene, the first call to move_and_slide() in the new scene will
generate an error because KinematicBody2D keeps internaly a
RID on_floor_body of a body resource in the old scene which no more has
a space assigned.
To fix this, on_floor_body is set to empty RID in response to
NOTIFICATION_ENTER_TREE notification of KinematicBody2D and
KinematicBody. Also all other data related to move_and_slide() is reset:
floor, ceiling, wall flags, colliders vector, floor_velocity.
This fixes#31416.
- Refer to properties explicitly when possible
- When multiple warnings are returned, always separate them by one
blank line to make them easier to distinguish
- Improve grammar and formatting
It's not necessary, but the vast majority of calls of error macros
do have an ending semicolon, so it's best to be consistent.
Most WARN_DEPRECATED calls did *not* have a semicolon, but there's
no reason for them to be treated differently.
- moved new infinite_inertia argument of move_and_slide and
move_and_slide_with_snap in KinematicBody and KinematicBody2D to the
end if not already there. This makes the order of arguments consistent
and should keep projects from 3.0 compatible as this argument did not
exist in 3.0. Docs updated accordingly.
- renamed max_bounces to max_slides for consistency. Docs updated
accordingly.
- the argument infinite_inertia in test_move is now optional, as it is
in every other movement related method. This closes#22829.
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.
Without this change any new PhysicsBody would show deprecation warnings
due to default values for friction and bounce being defined.
It also enforced a physics material override even when using default
values.
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
Notable potentially breaking changes:
- PROPERTY_USAGE_NOEDITOR is now PROPERTY_USAGE_STORAGE | PROPERTY_USAGE_NETWORK, without PROPERTY_USAGE_INTERNAL
- Some properties were renamed, and sometimes even shadowed by new ones
- New getter methods (some virtual) were added
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.
- Makes vararg methods automatically use PROPERTY_USAGE_NIL_IS_VARIANT on return types
- Completely removes the ":type" suffix for method names. Virtual methods must use the MethodInfo constructors that takes Variant::Type or PropertyHint as the first parameter for the return type (with CLASS_INFO as a helper to get the PropertyInfo). Parameters must use PROPERTY_HINT_RESOURCE_TYPE and hint string.
- PROPERTY_USAGE_NIL_IS_VARIANT is no longer needed for parameters, because parameters cannot be void.
- Adds missing PROPERTY_USAGE_NIL_IS_VARIANT to virtual and built-in methods that return Variant.
Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.
This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.
It is explained in this article: https://www.viva64.com/en/b/0226/
-Added ability to disable individual collisionshape/polygon
-Moved One Way Collision to shape, allowing more flexibility
-Changed internals of CollisionObject, shapes are generated from child nodes on the fly, not stored inside any longer.
-Modifying a CollisionPolygon2D on the fly now works, it can even be animated.
Will port this to 3D once well tested. Have fun!
As it turns out, is_ceiling would be true when hitting a wall,
and is_wall would be true momentarily when hitting a ceiling.
This makes a tiny one-line change to fix that.
Without trying to explain the code for anyone else having to
mess around with it.
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.
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).
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!
You can't set this value very well, since it's automatically computed
from the mass and the collision shapes. But since the values are higher
than many people might suspect, so being able to read it helps estimate
the amount of torque you might need to apply.
