From 329818f20b455bd5026878ee4ed15df4d50abc62 Mon Sep 17 00:00:00 2001 From: Raul Santos Date: Sun, 6 Mar 2022 18:04:29 +0100 Subject: Support explicit values in flag properties, add C# flags support - Add support for explicit values in properties using `PROPERTY_HINT_FLAGS` that works the same way it does for enums. - Fix enums and flags in VisualScriptEditor (it wasn't considering the explicit value). - Use `PROPERTY_HINT_FLAGS` for C# enums with the FlagsAttribute instead of `PROPERTY_HINT_ENUM`. --- modules/mono/csharp_script.cpp | 6 ++++-- modules/mono/glue/GodotSharp/GodotSharp/Core/MarshalUtils.cs | 5 +++++ modules/mono/mono_gd/gd_mono_cache.cpp | 2 ++ modules/mono/mono_gd/gd_mono_cache.h | 1 + modules/mono/mono_gd/gd_mono_utils.cpp | 8 ++++++++ modules/mono/mono_gd/gd_mono_utils.h | 1 + 6 files changed, 21 insertions(+), 2 deletions(-) (limited to 'modules/mono') diff --git a/modules/mono/csharp_script.cpp b/modules/mono/csharp_script.cpp index bee4e0e1fb..622838b308 100644 --- a/modules/mono/csharp_script.cpp +++ b/modules/mono/csharp_script.cpp @@ -2807,7 +2807,8 @@ int CSharpScript::_try_get_member_export_hint(IMonoClassMember *p_member, Manage GD_MONO_ASSERT_THREAD_ATTACHED; if (p_variant_type == Variant::INT && p_type.type_encoding == MONO_TYPE_VALUETYPE && mono_class_is_enum(p_type.type_class->get_mono_ptr())) { - r_hint = PROPERTY_HINT_ENUM; + MonoReflectionType *reftype = mono_type_get_object(mono_domain_get(), p_type.type_class->get_mono_type()); + r_hint = GDMonoUtils::Marshal::type_has_flags_attribute(reftype) ?
