Uninitialzed values in GDScript are of type NIL so not allowing null
comparisons did end up breaking some code.
This commit reenables NULL equality checks for all types. We're going to
have to figure out how to make this fast for the compiler later.
We now allow booleanization of all types. This means that empty versions
of all types now evaluate to false. So a Vector2(0,0), Dictionary(),
etc.
This allows you to write GDScript like:
if not Dictionary():
print("Empty dict")
Booleanization can now also no longer fail. There is no more valid flag,
this changes Variant and GDNative API.
After a short discussion with @reduz and @karroffel we decided to make
all non number/number comparisons return type errors on comparisons.
Now bool == bool is allowed but Vector2 == Vector3 is a type error and
no longer 'not equal'. The same has been done for the != operators.
In addition I forgot to add some failures to some Object operators
meaning that there was a potential for a crasher.
In an effort to make GDScript a little faster replace the double
switch() with a computed goto on compilers that set __GNUC__. For
compilers that don't support computed goto it will fall back to regular
switch/case statements.
In addition disable using boolean values in a mathematical context. Now
boolean values can only be compared with other booleans. Booleans will
also no longer be coerced to integers.
This PR replaces #11308 and fixes#11291
-Added ability to set/get a field in GetSet, as well as assignment ops
-Added a Select node
-Fixed update bugs related to variable list and exported properties, closes#9458
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
- Add FIXME tags comments to some unfixed potential bugs
- Remove some checks (always false: unsigned never < 0)
- Fix some if statements based on reviews.
- Bunch of missing `else` statements
After discussing this with Reduz this seemed like the best way to
fix#7354. This will make composite values that contain NaN in the same
places as well as the same other values compare as the same.
Additionally non-composite values now also compare equal if they are
both NaN. This breaks IEEE specifications but this is probably what most
users expect. There is a GDScript function check for NaN if the user
needs this information.
This fixes#7354 and probably also fixes#6947
Made sure files in core/ and tools/ have a proper Godot license header
when written by us. Also renamed aabb.{cpp,h} and object_type_db.{cpp,h}
to rect3.{cpp,h} and class_db.{cpp,h} respectively.
Also added a proper header to core/io/base64.{c,h} after clarifying
the licensing with the original author (public domain).
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!
Negative indexing is a useful feature in Python, especially when combined
with array slicing. Array slicing will hopefully be implemented later, but
negative indexing is useful in its own right.
A negative index is indexing from the end of an array,
"array[-1] == array[array.size()-1]", using a negative index
larger/smaller than the length of the array is still an error.
While primarily useful for arrays and strings, support is also added to
"array like" structures like Vector3 and Color. This is done just
to be consistent; vector3[2] is much clearer than vector3[-1], but disallowing
it while allowing it for an array with 3 elements seems confusing.
In preparation for the following "allow negative indexing" commit,
replace the repetitive array "set index" and "get index" code with
macros.
no functional changes were made, the resulting machine code is unchanged.
This might break some animations that use int tracks in continuous mode, but it should provide a more uniform interpolation for things like sprite frames.
