How is the variable coors updated to display mouse coordinates?

The update of the variable "coors" to display mouse coordinates is achieved by removing and re-adding the Text object each time. This approach allows for a dynamic update of the displayed information on the screen. When the mouse coordinates change, the previous Text object is removed to avoid overlap and clutter, and a new Text object is created with the updated values.

This method ensures that only the latest coordinates are shown, providing a clear and accurate indication of the mouse position without the confusion of multiple overlapping texts. In contrast, simply adding a new Text object after each click could cause multiple text instances to accumulate on the screen, which would make it unclear which coordinates are the most recent. Changing the position of the existing Text object or appending to it would not effectively refresh the displayed coordinates in a way that is visually clear, as it could lead to display issues or less effective updates.
