I'm trying to understand the advantages of using setget in code.
You've used this piece of code:
.
.
.
var controls: = KBD_MOUSE setget set_controls
func _input(event):
if event is InputEventJoypadButton or event is InputEventJoypadMotion:
if controls == KBD_MOUSE:
self.controls = GAMEPAD
elif event is InputEventMouse and controls == GAMEPAD:
self.controls = KBD_MOUSE
func set_controls(value: int) -> void:
controls = value
emit_signal("controls_changed")
Is it possible to arrive to the same result using this code?
.

.
var controls: = KBD_MOUSE
func _input(event):
if event is InputEventJoypadButton or event is InputEventJoypadMotion:
if controls == KBD_MOUSE:
self.controls = GAMEPAD
set_controls(1)
elif event is InputEventMouse and controls == GAMEPAD:
self.controls = KBD_MOUSE
set_controls(0)
func set_controls(value: int) -> void:
controls = value
emit_signal("controls_changed")
So, what is the advantage of using setget? Thanks!
When you use a setter function, any other class or script that changes controls will have it go through the setter. While in your example, assigning a new value to the controls and calling set_controls do two different things.
In general, you want to use a setter function whenever you want to process a value assigned to a variable in some way. For example
var max_health := 100.0
var health := max_health setget set_health
func set_health(value: float) -> void:
health = clamp(value, 0.0, max_health)
if is_equal_approx(health, 0.0):
emit_signal("health_depleted")
