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. Make sure to like, share, and of course subscribe! 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(de …...more
