在GODOT中让相机跟随物体的脚本是什么？

Question

当我将脚本应用于GODOT中的相机以使相机跟随车身时，代码是什么？我得到的here代码是在youtube上的，但是教程中的文本太小了，我看不懂。这是我的代码：

extends Camera

export (NodePath) var follow_this_path = null
export var target_distance = 3.0
export var target_height = 2.0

var follow_this = null
var last_lookat

func _ready():
    follow_this = get_node(follow_this_path)
    last_lookat = follow_this.global_transform.origin

func _physics_proceed(delta):
    var delta_v = global_transform.origin - follow_this.global_transform.origin
    var target_pos = global_transform.origin

    # ignore y
    delta_v.y = 0.0

    if (delta_v.length() > target_distance):
        delta_v = delta_v.normalized() + target_distance
        delta_v.y = target_height
        target_pos = follow_this.global_transform.origin + delta_v
    else:
        target_pos.y = follow_this.global_transform.origin.y + target_height

    global_transform.origin = global_transform.origin.linear_interpolate(target_pos, delta + 20.0)

    last_lookat = last_lookat.linear_interpolate(follow_this.global_transform.origin, delta + 20.0)

    look_at(last_lookat, Vector3(0.0, 1.0, 0.0))

据我所知，如果你在相机检查器中设置了"Current“属性，它将自动跟随车辆，假设相机是你车辆的孩子。
