The GetOrAddComponent<T> method is a generic method of the GameObject class that attempts to retrieve a component of type T from the GameObject. If the component does not exist, it adds a new component of type T to the GameObject. The method also allows you to specify whether the component should be enabled upon creation.
To use the GetOrAddComponent<T> method, call it on an instance of GameObject, specifying the type of component you want to retrieve or add. Pass a boolean value to the startEnabled parameter to determine if the component should be enabled when added.
Type Parameters:
T: The type of component to retrieve or add. This must be a type that inherits from Component.Parameters:
startEnabled (Boolean): If true, the component will be enabled when added. If false, it will be added in a disabled state.Returns:
T: The component of type T that was retrieved or added.// Example of using GetOrAddComponent GameObject myGameObject = new GameObject(); // Attempt to get a Rigidbody component, or add one if it doesn't exist Rigidbody rb = myGameObject.GetOrAddComponent<Rigidbody>(true); // The Rigidbody component is now guaranteed to be part of myGameObject // and is enabled if it was newly added.
