2022-08-22C#: Add source generator for method listIgnacio Roldán Etcheverry
2022-08-22C#: Add source generator for signals as eventsIgnacio Roldán Etcheverry
Changed the signal declaration signal to: ``` // The following generates a MySignal event [Signal] public delegate void MySignalEventHandler(int param); ```
2022-08-22C#: Re-implement assembly reloading with ALCsIgnacio Roldán Etcheverry
2022-08-22C#: Re-introduce exception logging and error stack traces in editorIgnacio Roldán Etcheverry
These two had been disabled while moving to .NET 5, as the previous implementation relied on Mono embedding APIs.
2022-08-22C#: Ensure we only create one CSharpScript per typeIgnacio Roldán Etcheverry
Previously, for each scripts class instance that was created from code rather than by the engine, we were constructing, configuring and assigning a new CSharpScript. This has changed now and we make sure there's only one CSharpScript associated to each type.
2022-08-22C#: Add source generator for properties and exports default valuesIgnacio Roldán Etcheverry
The editor no longer needs to create temporary instances to get the default values. The initializer values of the exported properties are still evaluated at runtime. For example, in the following example, `GetInitialValue()` will be called when first looks for default values: ``` [Export] int MyValue = GetInitialValue(); ``` Exporting fields with a non-supported type now results in a compiler error rather than a runtime error when the script is used.
2022-08-22C#: Begin move to .NET CoreIgnacio Roldán Etcheverry
We're targeting .NET 5 for now to make development easier while .NET 6 is not yet released. TEMPORARY REGRESSIONS --------------------- Assembly unloading is not implemented yet. As such, many Godot resources are leaked at exit. This will be re-implemented later together with assembly hot-reloading.
2022-08-22C#: Restructure code prior move to .NET CoreIgnacio Roldán Etcheverry
The main focus here was to remove the majority of code that relied on Mono's embedding APIs, specially the reflection APIs. The embedding APIs we still use are the bare minimum we need for things to work. A lot of code was moved to C#. We no longer deal with any managed objects (`MonoObject*`, and such) in native code, and all marshaling is done in C#. The reason for restructuring the code and move away from embedding APIs is that once we move to .NET Core, we will be limited by the much more minimal .NET hosting. PERFORMANCE REGRESSIONS ----------------------- Some parts of the code were written with little to no concern about performance. This includes code that calls into script methods and accesses script fields, properties and events. The reason for this is that all of that will be moved to source generators, so any work prior to that would be a waste of time. DISABLED FEATURES ----------------- Some code was removed as it no longer makes sense (or won't make sense in the future). Other parts were commented out with `#if 0`s and TODO warnings because it doesn't make much sense to work on them yet as those parts will change heavily when we switch to .NET Core but also when we start introducing source generators. As such, the following features were disabled temporarily: - Assembly-reloading (will be done with ALCs in .NET Core). - Properties/fields exports and script method listing (will be handled by source generators in the future). - Exception logging in the editor and stack info for errors. - Exporting games. - Building of C# projects. We no longer copy the Godot API assemblies to the project directory, so MSBuild won't be able to find them. The idea is to turn them into NuGet packages in the future, which could also be obtained from local NuGet sources during development.
2022-08-22C#: Move marshaling logic and generated glue to C#Ignacio Roldán Etcheverry
We will be progressively moving most code to C#. The plan is to only use Mono's embedding APIs to set things at launch. This will make it much easier to later support CoreCLR too which doesn't have rich embedding APIs. Additionally the code in C# is more maintainable and makes it easier to implement new features, e.g.: runtime codegen which we could use to avoid using reflection for marshaling everytime a field, property or method is accessed. SOME NOTES ON INTEROP We make the same assumptions as GDNative about the size of the Godot structures we use. We take it a bit further by also assuming the layout of fields in some cases, which is riskier but let's us squeeze out some performance by avoiding unnecessary managed to native calls. Code that deals with native structs is less safe than before as there's no RAII and copy constructors in C#. It's like using the GDNative C API directly. One has to take special care to free values they own. Perhaps we could use roslyn analyzers to check this, but I don't know any that uses attributes to determine what's owned or borrowed. As to why we maily use pointers for native structs instead of ref/out: - AFAIK (and confirmed with a benchmark) ref/out are pinned during P/Invoke calls and that has a cost. - Native struct fields can't be ref/out in the first place. - A `using` local can't be passed as ref/out, only `in`. Calling a method or property on an `in` value makes a silent copy, so we want to avoid `in`. REGARDING THE BUILD SYSTEM There's no longer a `mono_glue=yes/no` SCons options. We no longer need to build with `mono_glue=no`, generate the glue and then build again with `mono_glue=yes`. We build only once and generate the glue (which is in C# now). However, SCons no longer builds the C# projects for us. Instead one must run `build_assemblies.py`, e.g.: ```sh %godot_src_root%/modules/mono/build_scripts/build_assemblies.py \ --godot-output-dir=%godot_src_root%/bin \ --godot-target=release_debug` ``` We could turn this into a custom build target, but I don't know how to do that with SCons (it's possible with Meson). OTHER NOTES Most of the moved code doesn't follow the C# naming convention and still has the word Mono in the names despite no longer dealing with Mono's embedding APIs. This is just temporary while transitioning, to make it easier to understand what was moved where.

2022-05-20Add a new HashSet templatereduz
* Intended to replace RBSet in most cases. * Optimized for iteration speed
2022-05-16Replace most uses of Map by HashMapreduz
* Map is unnecessary and inefficient in almost every case. * Replaced by the new HashMap. * Renamed Map to RBMap and Set to RBSet for cases that still make sense (order matters) but use is discouraged. There were very few cases where replacing by HashMap was undesired because keeping the key order was intended. I tried to keep those (as RBMap) as much as possible, but might have missed some. Review appreciated!
2022-05-12Add a new HashMap implementationreduz
Adds a new, cleaned up, HashMap implementation. * Uses Robin Hood Hashing (https://en.wikipedia.org/wiki/Hash_table#Robin_Hood_hashing). * Keeps elements in a double linked list for simpler, ordered, iteration. * Allows keeping iterators for later use in removal (Unlike Map<>, it does not do much for performance vs keeping the key, but helps replace old code). * Uses a more modern C++ iterator API, deprecates the old one. * Supports custom allocator (in case there is a wish to use a paged one). This class aims to unify all the associative template usage and replace it by this one: * Map<> (whereas key order does not matter, which is 99% of cases) * HashMap<> * OrderedHashMap<> * OAHashMap<>
2022-05-03Remove `RES` and `REF` typedefs in favor of spelled out `Ref<>`Hugo Locurcio
These typedefs don't save much typing compared to the full `Ref<Resource>` and `Ref<RefCounted>`, yet they sometimes introduce confusion among new contributors.
2022-03-27Add GDExtension support to Scriptreduz
* Ability to create script languages from GDExtension * Some additions to gdnative_extension.h to make this happen * Moved the GDExtension binder to core This now allows creating scripting languages from GDExtension, with the same ease as if it was a module. It replaces the old PluginScript from Godot 3.x. Warning: GodotCPP will need to be updated to support this (it may be a bit of work as ScriptInstance needs to be created over there again).
2022-03-09Remove VARIANT_ARG* macrosreduz
* Very old macros from the time Godot was created. * Limited arguments to 5 (then later changed to 8) in many places. * They were replaced by C++11 Variadic Templates. * Renamed methods that take argument pointers to have a "p" suffix. This was used in some places and not in others, so made it standard. * Also added a dereference check for Variant*. Helped catch a couple of bugs.

2021-06-01[Net] Refactor RPCs, remove RSETsFabio Alessandrelli
In this PR: - Removed rset - rpc_config can now optionally configure transfer mode (reliable/unreliable/ordered) and channel (channels are not actually implemented yet.) - Refactor how the RPC id is computed to minimize the logic in Node and scripts that now only needs a single `get_rpc_methods` function.

2021-03-15C#: Fix disconnecting event signals twiceIgnacio Etcheverry
`disconnect_event_signals` can be called twice (when managed instance is disposed and from the ScriptInstance destructor).
2021-03-06Add C# source generator for a new ScriptPath attributeIgnacio Etcheverry
This source generator adds a newly introduced attribute, `ScriptPath` to all classes that: - Are top-level classes (not inner/nested). - Have the `partial` modifier. - Inherit `Godot.Object`. - The class name matches the file name. A build error is thrown if the generator finds a class that meets these conditions but is not declared `partial`, unless the class is annotated with the `DisableGodotGenerators` attribute. We also generate an `AssemblyHasScripts` assembly attribute which Godot uses to get all the script classes in the assembly, eliminating the need for Godot to search them. We can also avoid searching in assemblies that don't have this attribute. This will be good for performance in the future once we support multiple assemblies with Godot script classes. This is an example of what the generated code looks like: ``` using Godot; namespace Foo { [ScriptPathAttribute("res://Player.cs")] // Multiple partial declarations are allowed [ScriptPathAttribute("res://Foo/Player.cs")] partial class Player {} } [assembly:AssemblyHasScripts(new System.Type[] { typeof(Foo.Player) })] ``` The new attributes replace script metadata which we were generating by determining the namespace of script classes with a very simple parser. This fixes several issues with the old approach related to parser errors and conditional compilation. It also makes the task part of the MSBuild project build, rather than a separate step executed by the Godot editor.
2021-02-11Improve resource load cachereduz
-Added a new method in Resource: reset_state , used for reloading the same resource from disk -Added a new cache mode "replace" in ResourceLoader, which reuses existing loaded sub-resources but resets their data from disk (or replaces them if they chaged type) -Because the correct sub-resource paths are always loaded now, this fixes bugs with subresource folding or subresource ordering when saving.
2021-01-01Update copyright statements to 2021Rémi Verschelde
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 🎆

2020-10-13Fix code duplication in CSharpScriptopl-
Removes code duplication between `CSharpScript::reload()` and `CSharpScript::initialize_for_managed_type()`. Removes a redundant `CSharpScript::update_exports()` call in `CSharpLanguage::reload_assemblies()` as `CSharpScript::reload()` already calls it when appropriate. Fixes missing update of RPC information in `CSharpScript::initialize_for_managed_type()`.
2020-07-24Remove multilevel callsGeorge Marques
In general they are more confusing to users because they expect inheritance to fully override parent methods. This behavior can be enabled by script writers using a simple super() call.
