在 Unity 中设置技能

问题描述

过去一个月+我通过在 Unity 中制作游戏学到了很多东西。这样做很有趣。但有些事情仍然让我感到困惑。我正在尝试为角色设置一项技能，并且进展顺利。当角色施展技能时，技能会在角色后面而不是在前面。所以我想用位置和旋转来让它工作，但仍然没有。值得一提的是，预制件有自己的运动。所以到目前为止我的代码是这样的。因此，帮助会很大，并且非常感谢有关技能系统背后逻辑的一些教学。所以看看：

using UnityEngine;

public class MagicSkill : MonoBehavIoUr
{
    public GameObject hand; // Players right hand
    public GameObject fireballPrefab; // Fireball particle
    Vector3 fireballPos; // Adding the transform.position from the players hand
    Quaternion fireballRot; // Adding the rotation of the players hand
    private bool ispressed = false; //Skill button (mobile)
    public Animator animator; // Casting spell animation

void Update()
{
    fireballPos = hand.transform.position; // Getting the position of the hand for Instatiating
    fireballRot.x = hand.transform.rotation.x; // Getting the rotation of the hand for x Axis
    fireballRot.y = hand.transform.rotation.y; // Getting the rotation of the hand for y Axis (Here i try to modify the values but still nothing)
    fireballRot.z = hand.transform.rotation.z; // Getting the rotation of the hand for z Axis

    if (ispressed == true)
    {
        animator.SetBool("Magic",true);

        if (hand.transform.position.y >= 20) // Here I got the exact position of the hand for when to 
        Instatiate the skill
        {
            for (int i = 0; i < 1; i++) // For some reason it instatiates too many prefabs (I think it's because it's in Update method)
            {
                Instantiate(fireballPrefab,fireballPos,Quaternion.Euler(fireballRot.x,fireballRot.y,fireballRot.z));
                Invoke("Update",2.0f); // I'm trying to slow down the pressed button so that it want spawn every frame
            }
        }
    }
    else
    {
        animator.SetBool("Magic",false);
    }
}

public void MagicSkills()
{
    if (ispressed == false)
    {
        ispressed = true;
    }
    else
    {
        ispressed = false;
    }
}
}

解决方法

在对代码进行一些尝试后，我设法找到了解决方案。在这里，我至少为我发布了工作代码。也许它也会对其他人有所帮助。为了使其正常工作，您必须从您的按钮。非常感谢您的帮助Guilherme Schaidhauer Castro

using UnityEngine;

public class MagicSkill : MonoBehaviour
{
public GameObject hand; // Players right hand
public GameObject fireballPrefab; // Fireball particle
public Animator animator; // Casting spell animation
Vector3 fireballPos; // Adding the transform.position from the players hand
private bool isPressed = false; //Skill button (mobile)

void Update()
{
    fireballPos = hand.transform.position; // Getting the position of the hand for Instatiating

    if (isPressed == true)
    {
        animator.SetBool("Magic",true);

        if (hand.transform.position.y >= 20) // Here I got the exact position of the hand for when to Instatiate the skill
        {
            Instantiate(fireballPrefab,fireballPos,Quaternion.identity);
            isPressed = false;
        }
    }
    else
    {
        animator.SetBool("Magic",false);
    }
}

public void MagicSkills()
{
    if (isPressed == false)
    {
        isPressed = true;
    }
    else
    {
        isPressed = false;
    }
}
}

保留对角色变换的引用，并使用该变换来实例化火球，而不是使用手的旋转。手的旋转相对于身体没有变化，所以这就是为什么球总是朝着同一个方向前进。
