In games, it is often necessary to execute some function at the end of an animation or at a specific moment in a certain frame. At this time, it can be achieved by adding Animation Events. After adding an event function on to a key frame, the animation system will match the corresponding function methods on the animation root node and execute them when the animation reaches the key frame.
Please refer to the frame events documentation before continuing.
