Stops the control flow and waits for the user to trigger the advancement ("next") action.
This can be useful if you want to implement some kind of slide show or when you want to display text as images and want to let the user deceide when the story should continue.
The "next" action by default is when the user clicks on the stage. It can also be bound to buttons using triggers.
. show @my_image
. break
. hide @my_image
Explanation: show
is executed immediately, hide
only after the user clicked on the screen or
pushed a button associated with "next".
