Question
Could anyone help me program this please? Basically, if the collation or area is touching “hero” then it will make a signal. Just hero I want it to be. I remember doing this and it was every scene it touched and not just hero.
Ehm… lets try this…
Create a script
extends Area2D
signal hero_detected
signal hero_exited
func _ready():
# Connect the built-in area detection signals
area_entered.connect(_on_area_entered)
area_exited.connect(_on_area_exited)
body_entered.connect(_on_body_entered)
body_exited.connect(_on_body_exited)
# Check for Area2D collisions
func _on_area_entered(area: Area2D):
if area.name == "hero":
hero_detected.emit()
func _on_area_exited(area: Area2D):
if area.name == "hero":
hero_exited.emit()
# Check for physics body collisions
func _on_body_entered(body: Node2D):
if body.name == "hero":
hero_detected.emit()
func _on_body_exited(body: Node2D):
if body.name == "hero":
hero_exited.emit()
Then
Create an Area2D node in your scene and attach the script to your Area2D node. After that add a CollisionShape2D as a child of the Area2D
(set up the collision shape thingy) and Connect the signals in the editor to handle the hero detection
func _on_hero_detected():
print("Hero entered the area!")
func _on_hero_exited():
print("Hero left the area!")
Hopefully gets this you in the right direction 
thx for your help!
