Objects::ScriptObject

ScriptableObject in Unified Engine

The ScriptableObject class provides a template for objects that need scripting capabilities within the Unified Engine. A ScriptableObject is intended to be inherited by other classes to allow them to attach to a game object and be updated in sync with the game loop.

Key Features:

• Inherits from ObjectComponent, making it part of the hierarchical tree structure of the engine.

• Designed for extensibility to enable scripting features for game objects.

Components:

Constructors:

• ScriptableObject(ObjectComponent* Parent): Constructs a ScriptableObject attached to a specified parent component.

Sample Implementation: Camera Controller

class CameraControl : public UnifiedEngine::ScriptableObject{
public:
    GameObject* OBJ;

    CameraControl(GameObject* Par, UnifiedEngine::ObjectComponent* Camera)
        : UnifiedEngine::ScriptableObject(Par)
    {
        OBJ = Part;

        OBJ = Par;
        OBJ->Name = "CamCam";

        instantiate(OBJ);

        this->OBJ->Children.push_back(Camera);
        Camera->Parent = OBJ;
    }

        if (UnifiedEngine::__GAME__GLOBAL__INSTANCE__->Input->Keyboard.KeyPressed(UnifiedEngine::Key_A))
