如何在npc瞄准动画时启用拍摄？

Posted 2021-04-01

我有一个动画师。首先，npc开始行走，然后他慢慢停下来瞄准。然后用脚本我做了，当我点击鼠标左键时它会拍摄。这是Animator中的最后一个拍摄状态。在walk状态和瞄准状态之间，我添加了一个参数并在转换中将其设置为true：

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Shooting : MonoBehaviour
{
    [SerializeField]
    private Transform[] firePoints;
    [SerializeField]
    private Rigidbody projectilePrefab;
    [SerializeField]
    private float launchForce = 700f;
    [SerializeField]
    private Animator anim;
    [SerializeField]
    private bool automaticFire = false;
    [SerializeField]
    private bool slowDownEffect = false;

    private void Start()
    {
        anim.SetBool("Shooting", true);
    }

    public void Update()
    {
        if (Input.GetButtonDown("Fire1") && automaticFire == false)
        {
            if (anim.GetBool("Shooting") == true)
            {
                anim.Play("SHOOTING");
                LaunchProjectile();
            }
        }
        else
        {
            if (automaticFire == true)
            {
                anim.Play("SHOOTING");
                LaunchProjectile();
            }
        }
    }

    private void LaunchProjectile()
    {
        foreach (var firePoint in firePoints)
        {
            Rigidbody projectileInstance = Instantiate(
                projectilePrefab,
                firePoint.position,
                firePoint.rotation);

            projectileInstance.AddForce(new Vector3(0, 0, 1) * launchForce);

            projectileInstance.gameObject.AddComponent<BulletDestruction>().Init();
        }
    }
}

问题是，当我运行游戏时，如果我点击鼠标左键“Fire1”，它将立即从步行动画跳转/改变为拍摄动画并开始拍摄。

我希望首先npc会走路然后它会改变为瞄准当他完成改变瞄准然后才能射击“Fire1”。

如果npc仍在行走或中间改变瞄准不允许射击。只有在npc处于瞄准动画时才能启用拍摄。

using System.Collections.Generic;
using UnityEngine;

public class Shooting : MonoBehaviour
{
    [SerializeField]
    private Transform[] firePoints;
    [SerializeField]
    private Rigidbody projectilePrefab;
    [SerializeField]
    private float launchForce = 700f;
    [SerializeField]
    private Animator anim;
    [SerializeField]
    private bool automaticFire = false;
    [SerializeField]
    private bool slowDownEffect = false;

    private void Start()
    {
        anim.SetBool("Shooting", true);
    }

    public void Update()
    {
        if (isAnimationStatePlaying(anim, 0, "AIMING") == true)
        {
            if (Input.GetButtonDown("Fire1") && automaticFire == false)
            {
                if (anim.GetBool("Shooting") == true)
                {
                    anim.Play("SHOOTING");
                    LaunchProjectile();
                }
            }
            else
            {
                if (automaticFire == true)
                {
                    anim.Play("SHOOTING");
                    LaunchProjectile();
                }
            }
        }
    }

    private void LaunchProjectile()
    {
        foreach (var firePoint in firePoints)
        {
            Rigidbody projectileInstance = Instantiate(
                projectilePrefab,
                firePoint.position,
                firePoint.rotation);

            projectileInstance.AddForce(new Vector3(0, 0, 1) * launchForce);

            projectileInstance.gameObject.AddComponent<BulletDestruction>().Init();
        }
    }

    bool isAnimationStatePlaying(Animator anim, int animLayer, string stateName)
    {
        if (anim.GetCurrentAnimatorStateInfo(animLayer).IsName(stateName))
            return true;
        else
            return false;
    }
}

我添加了isAnimationStatePlaying方法并在Update中使用它，它现在工作得非常好。
