The GetOrAddComponent<T> method is a generic method of the GameObject class that either retrieves an existing component of type T attached to the GameObject or adds a new component of type T if it does not already exist. This method is useful for ensuring that a GameObject has a specific component without needing to check for its existence manually.
To use the GetOrAddComponent<T> method, specify the type of component you want to retrieve or add as the generic type parameter T. The method also takes a boolean parameter startEnabled which determines whether the component should be enabled upon creation.
Example usage:
var myComponent = myGameObject.GetOrAddComponent<MyComponentType>(true);In this example, myComponent will be assigned the existing component of type MyComponentType if it exists on myGameObject. If it does not exist, a new component of type MyComponentType will be added to myGameObject and enabled if startEnabled is true.
// Example of using GetOrAddComponent GameObject myGameObject = new GameObject(); // Ensure the GameObject has a specific component var myComponent = myGameObject.GetOrAddComponent<MyComponentType>(true); // myComponent is now guaranteed to be a valid reference to a MyComponentType instance // attached to myGameObject, and it is enabled if it was newly added.
