I was following a 3D Kinematic car tutorial, but when i started adding the code it gave me this error: “The method “is_on_floor():” isn’t declared in the current class”
This is the entire script:
Car behavior parameters, adjust as needed
export var gravity = -20.0
export var wheel_base = 0.6 # distance between front/rear axles
export var steering_limit = 10.0 # front wheel max turning angle (deg)
export var engine_power = 6.0
export var braking = -9.0
export var friction = -2.0
export var drag = -2.0
export var max_speed_reverse = 3.0
Car state properties
var acceleration = Vector3.ZERO # current acceleration
var velocity = Vector3.ZERO # current velocity
var steer_angle = 0.0 # current wheel angle
func _physics_process(delta):
if is_on_floor():
get_input()
apply_friction(delta)
calculate_steering(delta)
acceleration.y = gravity
velocity += acceleration * delta
velocity = move_and_slide_with_snap(velocity, -transform.basis.y, Vector3.UP, true)
func apply_friction(delta):
if velocity.length() < 0.2 and acceleration.length() == 0:
velocity.x = 0
velocity.z = 0
var friction_force = velocity * friction * delta
var drag_force = velocity * velocity.length() * drag * delta
acceleration += drag_force + friction_force
func calculate_steering(delta):
var rear_wheel = transform.origin + transform.basis.z * wheel_base / 2.0
var front_wheel = transform.origin - transform.basis.z * wheel_base / 2.0
rear_wheel += velocity * delta
front_wheel += velocity.rotated(transform.basis.y, steer_angle) * delta
var new_heading = rear_wheel.direction_to(front_wheel)
var d = new_heading.dot(velocity.normalized())
if d > 0:
velocity = new_heading * velocity.length()
if d < 0:
velocity = -new_heading * min(velocity.length(), max_speed_reverse)
look_at(transform.origin + new_heading, transform.basis.y)
func _get_input():
pass
