|
|
Unique identifier for the unit.
|
|
game : Game
|
|
Reference to the main game object.
|
|
position : tuple
|
|

|
|
position_before : tuple
|
|
The position of the unit before the last update.
|
|
age : int
|
|
The age of the unit in game ticks.
|
|
speed : float
|
|
Movement speed of the unit.
|
|
partial_move : float
|
|
Partial movement progress for smooth animation.
|
|
bbox : tuple
|
|

|
|
stop : int
|
|
Number of ticks to remain stationary.
|
|
collision_layer : int
|
|
Collision layer for the optimized collision system.

Methods
|
|
-------
|
|
move()
|
|
Update unit position and state (must be implemented by subclasses).
|
|
draw()
|
|
Render the unit on screen (must be implemented by subclasses).
|
|
collisions()
|
|
Handle collisions with other units (optional override).
|
|
die()
|
|
Remove unit from game and handle cleanup.
