how to make a chest open only once key is held and in the chests detection zone

Question

extends StaticBody2D

signal chest_opened

var keytaken = false
var inchestzone = false

warning-ignore:unusedargument
func _onArea2Dbodyentered(body: PhysicsBody2D): #area2d - > key
if keytaken == false:
keytaken = true
$Sprite.queuefree()
warning-ignore:unusedargument

func process(delta):
if keytaken == true:
if inchestzone == true:
emitsignal("chest_opened")

warning-ignore:unusedargument
func _onchestzonebodyentered(body: PhysicsBody2D): #chest zone -> key
inchest_zone = true
extends StaticBody2D

onready var only_once : bool = true
onready var animationplayer = $AnimationPlayer

func _ready():
animationplayer.play("Idle")

func onKeychestopened():
if onlyonce == true:
animationplayer.play("Open")
onlyonce = false
If the player enters the chest's zone before having the key, the chest stays locked.
Although, as soon as the player obtains the key, the chest instantly opens.
Can anyone help me come up with a solution for this issue?
Thanks in advance!

Answer 1

You want to check to open the chest really only on two instances.

1. The player obtains the key. Check if they are in the chest zone.
2. The player enters the chest zone. Check if they have the key.

You can removed the process function. The reason the chest instantly opens when the player obtains the key is because in_chest_zone is never set to false. Set it to false when the player exists the chest zone.
