69/// The main component used for interaction with the controls and animation code.
70///
71/// Every frame, the game code should feed input this component on every controlled entity. What
72/// should be fed is:
73///
74/// * A basis - this is the main movement command - usually
75///   [`TnuaBuiltinWalk`](crate::builtins::TnuaBuiltinWalk), but there can be others. It is the
76///   game code's responsibility to ensure only one basis is fed at any given time, because basis
77///   can hold state and replacing the basis type restarts the state.
78///
79///   Refer to the documentation of [the implementors of
80///   `TnuaBasis`](crate::TnuaBasis#implementors) for more information.
81///
82/// * Zero or more actions - these are movements like jumping, dashing, crouching, etc. Multiple
83///   actions can be fed, but only one can be active at any given moment. Unlike basis, there is a
84///   smart mechanism for deciding which action to use and which to discard, so it is safe to feed
85///   many actions at the same frame.
86///
87///   Refer to the documentation of [the implementors of
88///   `TnuaAction`](crate::TnuaAction#implementors) for more information.
89///
90/// Without [`TnuaControllerPlugin`] this component will not do anything.
