min_max_slider

A double slider. The min value is saved to the x component and the max value to the y component of a Vector2 or Vector2i property.

Both bounds are expressions, so a bound can be a literal, another property, or a method call, and the slider follows it when it changes:

@tool # required for method calls in attributes
extends Node3D

@export
var max_hp: int = 100
@export
var max_stamina: int = 50

@export_custom(PROPERTY_HINT_NONE, "min_max_slider:0,max_hp")
var hp: Vector2 = Vector2(10, 50)
@export_custom(PROPERTY_HINT_NONE, "min_max_slider:0,get_max_stamina(50)")
var stamina: Vector2 = Vector2(10, 40)
@export_custom(PROPERTY_HINT_NONE, "min_max_slider:0,10")
var damage: Vector2 = Vector2(2, 8)
@export_custom(PROPERTY_HINT_NONE, "min_max_slider:1,60")
var level: Vector2i = Vector2i(20, 40)


func get_max_stamina(bonus_stamina: int):
    return self.max_stamina + bonus_stamina

Note

The attribute takes both bounds, in that order: min_max_slider:{min},{max}. Applied to anything other than a Vector2 or a Vector2i, it reports an error and the property falls back to its default widget.
