The GetOrAddComponent<T> method is used to retrieve a component of type T from the current GameObject. If the component does not exist, it will be added to the GameObject. This method is useful for ensuring that a specific component is present on a GameObject without needing to check for its existence beforehand.
To use the GetOrAddComponent<T> method, call it on an instance of a Component or GameObject. Specify the type of component you want to retrieve or add as the generic type parameter T. The startEnabled parameter determines whether the component should be enabled upon creation if it does not already exist.
// Example of using GetOrAddComponent
public class ExampleComponent : Component
{
public void Initialize()
{
// Ensure that the GameObject has a Rigidbody component
var rigidbody = GetOrAddComponent<Rigidbody>(startEnabled: true);
// Now you can safely use the Rigidbody component
rigidbody.ApplyForce(Vector3.Up * 10);
}
}
