本文介绍了一个基于Unity的游戏HUD罗盘系统实现细节，包括罗盘元素注册与更新逻辑、敌人指示器显示及方向标记等内容。

1. 总体层次设计

放在HUD下
Compass脚本：

using System.Collections.Generic;
using Unity.FPS.Game;//用于使用Transform m_PlayerTransform;
using Unity.FPS.Gameplay;
using UnityEngine;

namespace Unity.FPS.UI
{
   
   
    public class Compass : MonoBehaviour
    {
   
   
        public RectTransform CompasRect;
        public float VisibilityAngle = 180f;
        public float HeightDifferenceMultiplier = 2f;
        public float MinScale = 0.5f;
        public float DistanceMinScale = 50f;
        public float CompasMarginRatio = 0.8f;

        public GameObject MarkerDirectionPrefab;

        Transform m_PlayerTransform;
        Dictionary<Transform, CompassMarker> m_ElementsDictionnary = new Dictionary<Transform, CompassMarker>();

        float m_WidthMultiplier;
        float m_HeightOffset;

        void Awake()
        {
   
   
            PlayerCharacterController playerCharacterController = FindObjectOfType<PlayerCharacterController>();
            DebugUtility.HandleErrorIfNullFindObject<PlayerCharacterController, Compass>(playerCharacterController,
                this);
            m_PlayerTransform = playerCharacterController.transform;

            m_WidthMultiplier = CompasRect.rect.width / VisibilityAngle;
            m_HeightOffset = -CompasRect.rect.height / 2;
        }

        void Update()
        {
   
   
            // this is all very WIP, and needs to be reworked
