What is the main function of the 'mouseClickMethod' in the provided programs?

The 'mouseClickMethod' serves as an event handler that specifically responds to mouse click actions within the program. When the mouse is clicked, this method is activated, allowing the program to execute a series of predefined actions based on that click event. This feature is crucial for creating interactive experiences in animation and games, letting users engage with elements on the screen, such as starting animations, moving objects, or changing game states.

The focus of the method on responding to interactions is what distinguishes it from other functionalities, such as creating variables, setting timers, or initializing coordinates, all of which serve different purposes in programming but do not directly deal with user input events like mouse clicks.
