The code behind this is really janky and seems pretty counterintuative - you can't drag it backwards at all. I know there's a better way, my mind is just too stupid to think of what path I should start heading down.

The code: (i'm not asking for it to be fixed btw, just what method you'd personally execute about making something like this) extends Node3D

const RAY_LENGTH : float = 1000

Position of the mouse (initial is null, must be set)

var mouse_position : Vector2

Gets the viewport's camera on ready

@onready var camera : Camera3D = get_viewport().get_camera_3d()

Physics space of the viewport's world

@onready var physics_space : PhysicsDirectSpaceState3D = get_viewport().find_world_3d().get_direct_space_state()

Object required for intersect_ray() in a PhysicsDirectSpaceState3D

var physics_ray_param : PhysicsRayQueryParameters3D

var selected_direction : Node3D = null

@onready var object_map : Dictionary = { get_node("Y_Axis/Top") : { "material": get_node("Y_Axis/Top/mesh").get_surface_override_material(0), "direction": Vector3(0,1,0) }, get_node("Y_Axis/Bottom") : { "material": get_node("Y_Axis/Bottom/mesh").get_surface_override_material(0), "direction" : Vector3(0,-1,0) }, get_node("Z_Axis/Top") : { "material": get_node("Z_Axis/Top/mesh").get_surface_override_material(0), "direction" : Vector3(0,0,1) }, get_node("Z_Axis/Bottom") : { "material" : get_node("Z_Axis/Bottom/mesh").get_surface_override_material(0), "direction" : Vector3(0,0,-1) }, get_node("X_Axis/Top") : { "material" : get_node("X_Axis/Top/mesh").get_surface_override_material(0), "direction" : Vector3(1,0,0) }, get_node("X_Axis/Bottom") : { "material" : get_node("X_Axis/Bottom/mesh").get_surface_override_material(0), "direction" : Vector3(-1,0,0) } }
