Laser
A class to represent a laser beam effect in a terminal.
The Laser class is responsible for creating and managing a laser beam effect in a terminal. It handles the initialization of the laser beam, the creation of spark effects, repositioning of the laser beam, emitting sparks, and disabling the laser beam.
Methods:
Name | Description |
---|---|
reposition |
Coord) -> None: Repositions the laser beam to the target coordinate. |
emit |
int = 1) -> None: Emits a specified number of sparks from the laser beam. |
disable |
Disables the laser beam by setting the visibility of the beam characters to False. |
