I have a namespace with methods with which I would like to have an implicit fallback to a different method if the aforementioned method doesn't exist. As an example, here's how I made my states.

#pragma once
#include "godot_cpp/classes/character_body2d.hpp"
#include "statemachine/base/state_base.h"

namespace GameLogic::States::ColorState
{
	constexpr double MAX_TIMER { 3.0 };
	struct ColorStateData
	{
		STATESTRUCT();
		godot::Ref<godot::StateMachine> state_machine;
		CharacterBody2D* entity;
		double timer {0.0};
	};
	void setup_state(ColorStateData& data);
	void enter_state(ColorStateData& data);
	void physics_update_state(ColorStateData& data, double delta);
	void update_state(ColorStateData& data, double delta);
	void exit_state(ColorStateData& data);
	STATESPACE(ColorStateData, GameLogic::States::ColorState)
}

It would be nice if I didn't have to specify 5 methods each time. Can I build this check into STATESPACE? In C++ 17 by the way.

What I am doing:
Hello, I am working on something in C++ for Godot, but this is more of a C++ question than a Godot question. I have a singular X macro to register a struct into a system I made, but the logic is in many places, and considering I am updating this macro and adding variables, it'd be easier to have a specific macro that doesn't change.

Problem:
When I make an X macro from an X macro, it doesn't properly expand. As an example this file:

#pragma once
#include "statemachine/registry/state_registry_register.h"

#define X_GENERATE_KIND(DataType, NS) k##DataType,
enum class StateKind : std::uint8_t
{
    EACH_STATE_REGISTER(X_GENERATE_KIND)
    kUnknown
};
#undef X_GENERATE_KIND

has the macro on line 7 expand to X(something1, something2) instead of k##something1, or, in my case:

X(WalkStateData, GameLogic ::States ::WalkState) X(WalkBackStateData, GameLogic ::States ::WalkBackState);

I defined EACH_STATE_REGISTER like this:

#define REGISTER_TO_ESR(DataType, NS, fields) X(DataType, NS)

#define EACH_STATE_REGISTER(X) \
REGISTER_EACH_STATE(REGISTER_TO_ESR);

and the REGISTER_EACH_STATE as

#define REGISTER\_EACH\_STATE(State) \
State(WalkStateData, GameLogic::States::WalkState, NO_STATE_FIELDS) \
State(WalkBackStateData, GameLogic::States::WalkBackState, NO_STATE_FIELDS)

Can anyone tell me why this happens, and if this is even fixable? (c++ 17)

On a Dell G15 5530. Arch Linux with Hyprland. My CPU keeps staying at around 800MHz-1.1GHz, even though the base is 2.6 GHz, even during a resource intensive task. Anyone know why? (13th Gen i7-13650HX as shown in image)

My version is 0.55.4, running this in a hyper-v VM (standard session).

Am having issues with cursor hovering. Apps don't properly recognize where my cursor is. Only when I click (specifically the mouse down, holding does not move it) or when my cursor first hovers over an application. Hyprland itself finds my cursor just find, as it finds what app my cursor hovers over, and finds it well. How can I fix this?
