(Solved)Help with mouse input for third person game

[WyvernZ22]

I just started using the phantom camera and I've been trying to set it up for a third-person project I'm developing, but I don't know how to set the mouse input to move the camera around (I'm new to coding).

This is the script I'm trying to add the mouse input to. I'll also attach a picture of my scene:

extends CharacterBody3D

const MAX_SPEED = 10.0
const ACCELERATION = 20.0
const DECELERATION = 20.0
const JUMP_VELOCITY = 4.5

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

func _physics_process(delta):
	# Add the gravity.
	if not is_on_floor():
		velocity.y -= gravity * delta

	# Handle Jump.
	if Input.is_action_just_pressed("ui_accept") and is_on_floor():
		velocity.y = JUMP_VELOCITY

	# Get the input direction and handle the movement.
	var input_dir = Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
	var direction = (transform.basis * Vector3(input_dir.x, 0, input_dir.y)).normalized()
	
	if direction:
		# Apply acceleration towards the maximum speed
		var target_speed = direction.length() * MAX_SPEED
		velocity.x = lerp(velocity.x, direction.x * target_speed, ACCELERATION * delta)
		velocity.z = lerp(velocity.z, direction.z * target_speed, ACCELERATION * delta)
	else:
		# Apply deceleration if not moving
		velocity.x = move_toward(velocity.x, 0, DECELERATION * delta)
		velocity.z = move_toward(velocity.z, 0, DECELERATION * delta)

	# Clamp velocity to the maximum speed
	velocity.x = clamp(velocity.x, -MAX_SPEED, MAX_SPEED)
	velocity.z = clamp(velocity.z, -MAX_SPEED, MAX_SPEED)

	# Set animation parameters
	$AnimationTree.set("parameters/conditions/idle", input_dir == Vector2.ZERO && is_on_floor())
	$AnimationTree.set("parameters/conditions/walk", input_dir != Vector2.ZERO && is_on_floor())
	$AnimationTree.set("parameters/conditions/falling", !is_on_floor())
	$AnimationTree.set("parameters/conditions/landed", is_on_floor())

	move_and_slide()

@ramokz Sorry about the later post. I tried to close this one, thinking it would be better than following it up, but I found out I couldn't after creating the second one.

Using the third-person example scene, I set the mouse input to move the camera around with some reverse engineering and make my character face whatever the camera was looking at, but I couldn't make it face left, right, or back. How can I implement that in my script?

I tried to use look_at "$%Character.look_at(global_transform.origin + direction, Vector3.UP)", but the character faces the opposite side of the Input (ex: left if I pressed right) for a split of a second. It then never faces any direction again, just facing where the camera looks at.

If I understand it correctly, you essentially want to make the character turn towards the direction you've moving the character in? E.g. if you make your character go left, the character model should also be turning left?

Think what you're looking for isn't a look_at() solution, but rather a rotation setter, where you set the rotation of the character relative to the camera's rotation and based on the direction you press. The current look_at() approach doesn't seem to take that into account?

Though since this sounds more like a general code question, rather than specific to this addon, so you will likely get a better answer on dedicated game dev / Godot forums or channels. Will also likely to get more responses as I'm typically the only one in here 😄

I'll look into that. Hopefully it's an easy fix; That's literally the only thing I need lol
Thank you!
