enter code hereHelp,
I need help for my class. I need to change the area detector to detect different areas but it keeps crashing and the times I do change it and it only works for one instance and for the rest it usually ends whit a crash. (I do have the areas I need to detect in different scenes for adding multiple)

func _on_area_2d_area_entered(area) -> void:#Adds or subractrs if in area
	if area == "Wet":
		humidity = humidity-1
	if humidity < MinHum:
		humidity = MinHum
	if area == "dry":
		humidity = humidity+1
	if humidity < MaxHum:
		humidity = MaxHum

You are comparing a node (area) to a string. Find a way to add the wet or dry property to the areas, in a script, and then compare them properly.

something like this in the area script:

@export var type: string

and then compare the strings properly:

if area.type == "wet": do stuff
