Error: Octree::create

Sorry if this is obvious but I’m very new to this engine. I made a very simple platformer from a tutorial and I constantly get the errors listed below the moment I run the game. I have no idea how to debug this and it does not seem to cause any side-effects. There is no Stack Trace.

I did notice that deleting my Player and Enemy characters from the scene also gets rid of the errors.

0:00:00:0570 - Condition ’ Math::is_nan(p_aabb.size.x) ’ is true.
returned: 0
---------- Type:Error Description: Time: 0:00:00:0570 C Error: Condition ’ Math::is_nan(p_aabb.size.x) ’ is true. returned: 0 C
Source: core\math\octree.h:807 C Function: Octree<struct
VisualServerScene::Instance,1,class DefaultAllocator>::create

When I delete only the player from my starting scene I get this error instead:

0:00:00:0691 - Condition ’ p_aabb.position.y > 1e15 ||
p_aabb.position.y < -1e15 ’ is true. returned: 0
---------- Type:Error Description: Time: 0:00:00:0691 C Error: Condition ’ p_aabb.position.y > 1e15 || p_aabb.position.y < -1e15 ’ is
true. returned: 0 C Source: core\math\octree.h:802 C Function:
Octree<struct VisualServerScene::Instance,1,class

My code: (Player and Enemies inherit from this)

extends KinematicBody2D

var Hitpoints = 1;
const GRAVITY = 20
const UP = Vector2(0, -1)
var Motion = Vector2()

Player code

extends "res://Scripts/"

var Direction = 1
var MoveSpeed = 20

export var HasCliffDetection = true
export var HasWallDetection = true

onready var RayLeft = get_node("RayLeft")
onready var RayRight = get_node("RayRight")
onready var RayDownLeft = get_node("RayDownLeft")
onready var RayDownRight = get_node("RayDownRight")

func _ready():

func _physics_process(delta):
	if HasCliffDetection and is_on_floor():
	if HasWallDetection and is_on_floor():
func Move():
	Motion = Vector2(MoveSpeed * Direction,GRAVITY)
	Motion = move_and_slide(Motion, UP);
func CliffDetection():
	if (Direction == 1) and not RayDownRight.is_colliding():
	elif (Direction == -1) and not RayDownLeft.is_colliding():
func WallDetection():
	if (Direction == 1) and RayRight.is_colliding():
	elif (Direction == -1) and RayLeft.is_colliding():
func Flip(newDirection = 0):
	if (newDirection == 0):
		Direction *= -1
		Direction = newDirection
	#$BaseEnemySprite.flip_h = (Direction == -1)

Note that removing and deriving directly from KinematicBody2D still produces the same errors.

I don’t have an answer for you but I do have a tip. You don’t need all those ‘pass’ statements except for the one on the func _ready().

All pass does is suppress syntax errors on empty blocks

Ah thanks good tip!

I’m also having a similar problem in my project, with the difference that in my case it crashes on the common case and if I’m lucky I get the position error and don’t crash. I’ll link the stack trace:

removing define REAL_T_IS_DOUBLE solved it for me
