Скачать или смотреть How To Grab Objects In Godot

Hello everybody, today I made a grab function in Godot which as always you can find on my discord at the about section.
Hope you enjoined watching.
Feel free to comment.

See you next time.

This is the code if you don't want it from the discord:
extends CharacterBody3D

@export var speed = 5
@export var jump_velocity = 5
@export var look_sensitivity = 0.01
@export var push = 5
@export var grab_force = 10
@export var release_force = 0.4
var grab:RigidBody3D #The current object we are grabbing

var gravity = ProjectSettings.get_setting("physics/3d/default_gravity")

@onready var camera:Camera3D = $Camera3D
@onready var grab_ray:RayCast3D = $"Camera3D/Grab Ray" #The raycast to check if there is something to grab
@onready var grab_target:Node3D = $"Camera3D/Grab Ray/Grab Target" #The taget of the grabbed object

func _ready(): Input.set_mouse_mode(Input.MOUSE_MODE_CAPTURED)

func _physics_process(delta):

if grab.get_colliding_bodies().is_empty() or (!grab.get_colliding_bodies().is_empty() and grab.get_colliding_bodies()[0] is RigidBody3D): grab.linear_velocity = grab_force * (grab_target.global_position - grab.global_position) #Is the grabbed object isn't colliding whith anything or that it is colliding with another rigidbody, then keep on grabbing by setting the velocity of the grabbed object to its relative position to the grab target times the grab force
else: release() #If not, then release the grabbed object
elif Input.is_action_just_pressed("Grab") and grab_ray.is_colliding() and grab_ray.get_collider() is RigidBody3D: #If there isn't a grabbed object, the grab action was just pressed, the ray hit something and it is a rigidbody
grab = grab_ray.get_collider() #Set the grabbed object to the ray hit
await get_tree().create_timer(0.2).timeout #Wait for 0.2 seconds to let the player pick up the object before checking for collisions
if grab: #If there is a grabbed object
grab.max_contacts_reported = 1 #Enable collision check on the grabbed object
grab.contact_monitor = true #Enable collision check on the grabbed object
elif grab: release() #Release the grabbed object

var input = Input.get_vector("move_left","move_right","move_forward","move_backward").normalized() * speed

velocity = input.x * global_basis.x + input.y * global_basis.z + Vector3(0, velocity.y, 0)

if is_on_floor():
if Input.is_action_just_pressed("jump"): velocity.y = jump_velocity
else: velocity.y -= gravity * delta

var c := get_slide_collision(i) #Get the colliding node

var push_dir = -c.get_normal() #The push direction is the oposite of the impact direction
var velocity_diff_in_push_dir = self.velocity.dot(push_dir) - c.get_collider().linear_velocity.dot(push_dir) #The push velocity calculated by subtructing the velocity of the player from the node compared to the direction
c.get_collider().apply_central_force(push_dir * velocity_diff_in_push_dir * push) #Aplly the force to the node times the push force variable

move_and_slide()

func _input(event):
if event is InputEventMouseMotion:
rotate_y(event.relative.x * -look_sensitivity)
camera.rotate_x(event.relative.y * -look_sensitivity)
camera.rotation.x = clamp(camera.rotation.x, -PI/2, PI/2)

func release():

grab.contact_monitor = false #Disable collision check on the grabbed object
grab.linear_velocity *= release_force #Apply the release force
