The Unity Scripting API Reference documentation lists some functions (for example, the various
GetComponent functions) with a variant that has a letter
T or a type name in angle brackets after the function name:
//C# void FuncName<T>();
These are generic functions. You can use them to specify the types of parameters and/or the return type when you call the function.
// The type is correctly inferred because it is defined in the function call var obj = GetComponent<Rigidbody>();
In C#, it can save a lot of keystrokes and cast; for example:
Rigidbody rb= (Rigidbody) go.GetComponent(typeof(Rigidbody));
Rigidbody rb = go.GetComponent<Rigidbody>();
Any function that has a generic variant listed on its Scripting API Reference documentation page allows this special calling syntax.
