Call a custom function on hitinfo entity

[ErhanK]

Hi. How can i call a custom function on my hitinfo entity?

if (PickResult) {
	if (PickInfo.entity->GetClass() == Entity::ModelClass) {
		if (PickInfo.entity->GetKeyValue("GameObjectType") == "NpcBase") {
			//PickInfo.entity-> ?? ex. GetHurt()
		}
	}
}

Do you want a Lua or C++ function to be called?

I want to call the custom function in a c++ class ... I have one more question. I don't know which is better. I've created a custom actor class. This class creates an entity within itself and attaches itself to it. Should I use this, or should I create an entity, also create a custom actor and then assign that actor to that entity? I gave an example below.

//Header
class EnemyBaseActor : public Actor {
public:
    EnemyBaseActor();
};
//CPP
EnemyBaseActor::EnemyBaseActor(){
    this->entity = Model::Load("Models/Zombie.mdl"); 
    this->entity->SetActor(this);   
}

OR

// In the main ex.
Entity* myEntity = Model::Load("Models/Zombie.mdl");
Actor* zombieActor = new EnemyBaseActor(); //My custom actor.
myEntity->SetActor(zombieActor);
//zombieActor->Release(); // It's doesn't work. So i didn'n write it.

it works in two ways, but which one is right?

Both of those code examples do the exact same thing.

Cast the Actor object to your custom actor object and the function will be available. See C++ dynamic casting.

So i need this :

if (PickInfo.entity->GetKeyValue("GameObjectType") == "NpcBase") {
	//NPC_Base is my custom actor
	NPC_Base* tmp = dynamic_cast<NPC_Base*>(PickInfo.entity->GetActor());
	tmp->DoSomething();
}

and thank you so much :)

A dynamic cast will return NULL if the conversion is not valid. (A static cast can potentially return an invalid object.) So you might want to also check if the result of the cast is NULL before continuing.

I should really write something on how I handle Actors. Not to brag but my system is just really nice. ?

you really must do
