钓鱼的核心玩法是： 甩钩，等待鱼咬钩后，再给予鱼线适当的力度把鱼给拉上来。 鱼的拉力用随机值模拟。 人的拉力则用按键来控制。如果不增加拉力，人对鱼竿的拉力会随着时间减小至0。按下L键时，就会在原拉力的基础上再给鱼竿增加一定的拉力。 如果人与鱼的拉力受力平衡时，可以看作是合适的拉力。 在合适的拉力范围内，积累一定的时间，即可将鱼钓上来。 鱼竿脚本 using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using DG.Tweening; public class Fishing : MonoBehaviour { /*--------------核心玩法----------------*/ public float lineTension = 0.5f; public float deviation = 0.1f; //偏差范围 public float resultantForce = 0; //合力 public float fishForce = 0; public float fishingRodForce = 0; public float fishingRodForceDeclinePerSec = 0.15f; //人的拉力每秒减少量 public float targetAccumulationTime = 5f; public float currentAccumulationTime = 0; public float accumulationRate = 0; //积累进度 /*--------------UI----------------*/ public GameObject canvas; public GameObject TensionPanel; public Image curTensionBar; //力度条 public Image acRateBar; //时间条 public Text status; //状态提示文本 public FishingStatus fishingStatus = FishingStatus.notAtFishing; public enum FishingStatus { wait, hit, caught, notAtFishing, } void Update() { AdjustLength(); if (fishingStatus == FishingStatus.caught) MoveWithHook(); if (fishingStatus == FishingStatus.hit) { AdjustTension(); } } void AdjustTension() { fishForce = Mathf.Lerp(fishForce, Random.Range(0, 1f), 0.2f); float fishingRodForceIncrease = (Input.GetKeyDown(KeyCode.L) ?
