My game keeps crashing and I’m not understanding why. I randomly get the error “Invalid access to property or key ‘position’ on a base object of type ‘InputEventKey’”.
Here’s my code:
extends CharacterBody3D
@onready var player := %Player
@onready var right_ray := %RightRayCast3D
@onready var left_ray := %LeftRayCast3D2
var we_are_colliding := false
func _physics_process(delta):
velocity = player.velocity
move_and_slide()
if position != player.position:
position = lerp(position,player.position,1*delta)
if right_ray.is_colliding():
rotation_degrees += Vector3(0,-1,0)
we_are_colliding = true
elif left_ray.is_colliding():
rotation_degrees += Vector3(0,1,0)
we_are_colliding = true
else:
we_are_colliding = false
func _input(event):
var org_pos := Vector2(300,600)
if Input.is_action_just_pressed("move_camera"):
org_pos = event.position
if Input.is_action_pressed("move_camera"):
if event is InputEventMouseMotion:
var rot = org_pos-event.position
if !we_are_colliding:
org_pos.x = deg_to_rad(org_pos.x)
rot.x = deg_to_rad(rot.x)
rotation.y = lerp_angle(org_pos.x,rot.x,1)
input events do not have “position”, especially key-events. Try adding some type hints to get better auto-complete, if your line numbers are green then the line is “type-safe” meaning you should not get invalid access errors. You can enable type hints in your editor settings, they should be enabled by default in 4.3
func _input(event):
# Mouse in viewport coordinates.
if event is InputEventMouseButton:
print("Mouse Click/Unclick at: ", event.position)
elif event is InputEventMouseMotion:
print("Mouse Motion at: ", event.position)
# Print the size of the viewport.
print("Viewport Resolution is: ", get_viewport().get_visible_rect().size)
And also, when you print(event) it displays a position, just not always, which is why the bug didn’t happen instantly.
