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 🎆
Storing script references to pointer only in result.script_type could
lead to losing the last reference, causing further conversions from
Script* to Ref<Script> to fail.
Now result.script_type_ref is always set first, and then cleared in the
specific case of the script being the owner, to avoid cyclic reference
issues.
- ClassDoc added to GDScript and property reflection data were extracted
from parse tree
- GDScript comments are collected from tokenizer for documentation and
applied to the ClassDoc by the GDScript compiler
- private docs were excluded (name with underscore prefix and doesn't
have any doc comments)
- default values (of non exported vars), arguments are extraced from the
parser
- Integrated with GDScript 2.0 and new enums were added.
- merge conflicts fixed
- Use the new functions in Variant to determine the validity and resulting
type of operators.
- Split the operator function in codegen between binary and unary, since
the unary ones have now a special requirement of having the second
argument to be the NIL type when requesting info.
They are now called "utility functions" to avoid confusion with methods
of builtin types, and be consistent with the naming in Variant.
Core utility functions are now available in GDScript. The ones missing
in core are added specifically to GDScript as helpers for convenience.
Some functions were remove when there are better ways to do, reducing
redundancy and cleaning up the global scope.
- Replace the for loop temporaries by locals. They cause conflicts with
the stack when being popped, while locals are properly handled in the
scope.
- Change the interface for the codegen so the for loop list doesn't live
through the whole block if it's a temporary.
- Keep track of the actual amount of local variables in the stack. Using
the size of the map is misleading in cases where multiple locals have
the same name (which is allowed when there's no shadowing).
- Added a few debug checks for temporaries, to avoid them being wrongly
manipulated in the future. They should not live more than a line of
code.
- Rearrange some of compiler code to make sure the temporaries don't
live across blocks.
Sometimes to fix something you have to break it first.
This get GDScript mostly working with the new tokenizer and parser but
a lot of things isn't working yet. It compiles and it's usable, and that
should be enough for now.
Don't worry: other huge commits will come after this.
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.
For us, it practically only changes the fact that `A<A<int>>` is now
used instead of the C++03 compatible `A<A<int> >`.
Note: clang-format 10+ changed the `Standard` arguments to fully
specified `c++11`, `c++14`, etc. versions, but we can't use `c++17`
now if we want to preserve compatibility with clang-format 8 and 9.
`Cpp11` is still supported as deprecated alias for `Latest`.
EngineDebugger is the new interface to access the debugger.
It tries to be as agnostic as possible on the data that various
subsystems can expose.
It allows 2 types of interactions:
- Profilers:
A subsystem can register a profiler, assigning it a unique name.
That name can be used to activate the profiler or add data to it.
The registered profiler can be composed of up to 3 functions:
- Toggle: called when the profiler is activated/deactivated.
- Add: called whenever data is added to the debugger
(via `EngineDebugger::profiler_add_frame_data`)
- Tick: called every frame (during idle), receives frame times.
- Captures: (Only relevant in remote debugger for now)
A subsystem can register a capture, assigning it a unique name.
When receiving a message, the remote debugger will check if it starts
with `[prefix]:` and call the associated capture with name `prefix`.
Port MultiplayerAPI, Servers, Scripts, Visual, Performance to the new
profiler system.
Port SceneDebugger and RemoteDebugger to the new capture system.
The LocalDebugger also uses the new profiler system for scripts
profiling.
Pass the calculated index from the stack and use the same to get and set
the value. This avoids a function with side effects being evaluated
twice when using indexing in an assignment with operation statement
(e.g. a[function()] += 1).
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.
Before this patch, assert() only took the condition to assert on:
assert(item_data)
Now, it can optionally take a string that will be printed upon failure:
assert(item_data, item_name + " has no item data in ItemDatabase")
This makes it easier to immediately see what the issue is by being
able to write informative failure messages.
Thanks to @wiped1 for sharing their patch, upon which this is based.
Closes#17082
They had been reserved for future implementation, but we now have the
`match` CF keyword which does the same and more.
According to @reduz `do` was even added by mistake when copying from
the shader language parser, it was never intended to add support for
`do`... `while` loops, as the syntax would be awkward in GDScript,
and the added sugar is not worth it.
Fixes#25787.
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.
- Typed assignment (built-in, native, and script).
- Cast (built-in conversion; native and script checks).
- Check type of functions arguments on call.
- Check type of members on set.
- Resolve types for all identifiers.
- Error when identifier is not found.
- Match return type and error when not returning a value when it should.
- Check unreachable code (code after sure return).
- Match argument count and types for function calls.
- Determine if return type of function call matches the assignment.
- Do static type check with match statement when possible.
- Use type hints to determine export type.
- Check compatibility between type hint and explicit export type.
- Tool scripts will be executed and can be accessed by plugins.
- Other script languages can implement add/remove_named_global_constant
to make use of this functionality.
