Registering usertype function issues: "is_noexcept': undeclared identifier,'traits_type' is not class... #1021
Description
Hello!
I am having issues registering a new user type's functions. I am getting
'is_noexcept': undeclared identifier
'traits_type': is not a class or namespace name
expression did not evaluate to a constant
from function_types_stateless.hpp 173
on all four of these registration strategies:
this->luaState.set_function("moveRight", &TIEntityScriptInterface::moveRight);
this->luaState.new_usertype<TIEntityScriptInterface>("tientity", sol::no_constructor,
"moveRight", &TIEntityScriptInterface::moveRight);
sol::usertype<TIEntityScriptInterface> interface_type = this->luaState.new_usertype<TIEntityScriptInterface>("tientity", "moveRight", &TIEntityScriptInterface::moveRight);
sol::usertype<TIEntityScriptInterface> interface_type = this->luaState.new_usertype<TIEntityScriptInterface>("tientity");
interface_type["moveRight"] = &TIEntityScriptInterface::moveRight; // Issue occurs when this line is introduced
Am I missing something from the documentation? (https://sol2.readthedocs.io/en/latest/tutorial/cxx-in-lua.html)
I'm on Windows 10, Visual Studio 2019, C++17, and I'm using sol v3.2.1.
Thank you!
For additional code, here's my TIEntityScriptInterface class:
class TIEntityScriptInterface {
public:
TIEntityScriptInterface(TIEntity&);
~TIEntityScriptInterface() {};
void moveRight();
...
private:
TIEntity* tientity = nullptr;
};
void TIEntityScriptInterface::moveRight() {
MovesComponent* movesComponent = this->tientity->getComponent<MovesComponent>();
SpriteComponent* spriteComponent = this->tientity->getComponent<SpriteComponent>();
if (movesComponent != nullptr) {
MovesComponentSystem::Instance()->setTargetPosition(*movesComponent, *spriteComponent, Direction::RIGHT);
}
}
...
