关于ui按钮与条件的统一

有条件的统一UI按钮的问题

尝试用按钮替换键

void SlashAttack () 
{
    // We look for the current state looking at the information of the animator
    AnimatorStateInfo stateInfo = anim.GetCurrentAnimatorStateInfo(0);
    bool loading = stateInfo.IsName("Player_Slash");

    // Ataque a distancia
    if (Input.GetKeyDown("p") || Input.GetKeyDown(KeyCode.Z))
    { 
        anim.SetTrigger("loading");
        aura.AuraStart();
    } 
    else if (Input.GetKeyUp("p") || Input.GetKeyUp(KeyCode.Z))
    { 
        anim.SetTrigger("attacking");
        if (aura.IsLoaded()) 
        {
            // Para que se mueva desde el principio tenemos que asignar un
            // valor inicial al movX o movY en el edtitor distinto a cero
            float angle = Mathf.Atan2(anim.GetFloat("movY"), anim.GetFloat("movX")) * Mathf.Rad2Deg;

            GameObject slashObj = Instantiate(slashPrefab, transform.position, Quaternion.AngleAxis(angle, Vector3.forward));

            Slash slash = slashObj.GetComponent<Slash>();
            slash.mov.x = anim.GetFloat("movX");
            slash.mov.y = anim.GetFloat("movY");
        }

        aura.AuraStop();
        StartCoroutine(EnableMovementAfter(0.4f));
    } 

    // Prevenimos el movimiento mientras cargamos
    if (loading) 
    { 
        movePrevent = true;
    }
}

快速反应：你不能因为UI.Button没有像button down或button up这样的回调

---

如果您真的不想更改当前的代码结构，可以使用IPointerDownHandler和IPointerUpHandler编写自己的组件，例如：喜欢

using UnityEngine;
using UnityEngine.EventSystems;

public class Example : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
{
    public bool isDown;
    public bool isUp;

    //Detect current clicks on the GameObject (the one with the script attached)
    public void OnPointerDown(PointerEventData pointerEventData)
    {
        isDown = true;
    }

    //Detect if clicks are no longer registering
    public void OnPointerUp(PointerEventData pointerEventData)
    {
        isUp = true;
    }

    // reset both in LateUpdate
    private void LateUpdate()
    {
        isDown = false;
        isUp = false;
    }
}

将其连接到您的按钮。

比你的代码引用依据组件

public Example PButton;

void SlashAttack () 
{
    // ...

    // Ataque a distancia
    if (Input.GetKeyDown("p") || Input.GetKeyDown(KeyCode.Z) || PButton.isDown)
    { 
        // ...
    } 
    else if (Input.GetKeyUp("p") || Input.GetKeyUp(KeyCode.Z) || PButton.isUp)
    { 
        // ...
    } 

    // ...
}

注意

确保场景中存在EventSystem以允许指针检测。对于非UI GameObjects上的指针检测，请确保将PhysicsRaycaster附加到Camera。

首先将单独的功能分解为单独的方法，例如：

public void OnKeyDown()
{
     anim.SetTrigger("loading");
     aura.AuraStart();
}

public void OnKeyUp()
{
    anim.SetTrigger("attacking");
    if (aura.IsLoaded()) 
    {
        // Para que se mueva desde el principio tenemos que asignar un
        // valor inicial al movX o movY en el edtitor distinto a cero
        float angle = Mathf.Atan2(anim.GetFloat("movY"), anim.GetFloat("movX")) * Mathf.Rad2Deg;

        GameObject slashObj = Instantiate(slashPrefab, transform.position, Quaternion.AngleAxis(angle, Vector3.forward));

        Slash slash = slashObj.GetComponent<Slash>();
        slash.mov.x = anim.GetFloat("movX");
        slash.mov.y = anim.GetFloat("movY");
    }

    aura.AuraStop();
    StartCoroutine(EnableMovementAfter(0.4f));
}

void SlashAttack () 
{
    // We look for the current state looking at the information of the animator
    AnimatorStateInfo stateInfo = anim.GetCurrentAnimatorStateInfo(0);
    bool loading = stateInfo.IsName("Player_Slash");

    // Ataque a distancia
    if (Input.GetKeyDown("p") || Input.GetKeyDown(KeyCode.Z))
    { 
       OnKeyDown();
    } 
    else if (Input.GetKeyUp("p") || Input.GetKeyUp(KeyCode.Z))
    { 
        OnKeyUp();
    } 

    // Prevenimos el movimiento mientras cargamos
    if (loading) 
    { 
        movePrevent = true;
    }
}

当我们将方法公之于众时，您现在可以将它们链接到UI。由于标准统一按钮仅支持单击，并且您的代码依赖于按钮释放，因此您可以使用EventTrigger组件来显示要链接到的事件
