In Lua full params EmitEvent is not bind?

[Dreikblack]

If do something like that in lua script:

EmitEvent(EVENT_WIDGETACTION, nil, 0, 0, 0, 0, 0, nil, "start.ultra")

This is the binding code. I can see from looking at it what the issue is. With sol, nil does not automatically map to shared pointers, so separate overloads have to be added to handle that.

		L->set_function("EmitEvent", sol::overload(
			[](const Event& e) { return EmitEvent(e); },
			[](const int id, shared_ptr<Object> source) { return EmitEvent(id, source); },
			[](const int id) { return EmitEvent(id); },
			[](const int id, shared_ptr<Object> source) { return EmitEvent(id, source); },
			[](const int id, shared_ptr<Object> source, const int data) { return LuaEmitEvent(id, source, data,0,0,0,0,nullptr,""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y) { return LuaEmitEvent(id, source, data, x, y, 0, 0, nullptr, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h) { return LuaEmitEvent(id, source, data, x, y, w, h, nullptr, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h, shared_ptr<Object> o) { return LuaEmitEvent(id, source, data, x, y, w, h, o, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h, shared_ptr<Object> o, std::string s) { return LuaEmitEvent(id, source, data, x, y, w, h, o, s); }
		));

I added all possible combinations of NULL pointers:

		L->set_function("EmitEvent", sol::overload(
			[](const Event& e) { return EmitEvent(e); },
			[](const int id, shared_ptr<Object> source) { return EmitEvent(id, source); },
			[](const int id) { return EmitEvent(id); },
			[](const int id, shared_ptr<Object> source) { return EmitEvent(id, source); },
			[](const int id, shared_ptr<Object> source, const int data) { return LuaEmitEvent(id, source, data,0,0,0,0,nullptr,""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y) { return LuaEmitEvent(id, source, data, x, y, 0, 0, nullptr, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h) { return LuaEmitEvent(id, source, data, x, y, w, h, nullptr, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h, shared_ptr<Object> o) { return LuaEmitEvent(id, source, data, x, y, w, h, o, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h, shared_ptr<Object> o, std::string s) { return LuaEmitEvent(id, source, data, x, y, w, h, o, s); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h, std::nullptr_t o) { return LuaEmitEvent(id, source, data, x, y, w, h, o, L""); },
			[](const int id, shared_ptr<Object> source, const int data, const int x, const int y, const int w, const int h, std::nullptr_t o, std::string s) { return LuaEmitEvent(id, source, data, x, y, w, h, o, s); },
			[](const int id, std::nullptr_t source) { return EmitEvent(id, source); },
			[](const int id, std::nullptr_t source, const int data) { return LuaEmitEvent(id, source, data, 0, 0, 0, 0, nullptr, ""); },
			[](const int id, std::nullptr_t source, const int data, const int x, const int y) { return LuaEmitEvent(id, source, data, x, y, 0, 0, nullptr, L""); },
			[](const int id, std::nullptr_t source, const int data, const int x, const int y, const int w, const int h) { return LuaEmitEvent(id, source, data, x, y, w, h, nullptr, L""); },
