用户释放鼠标按钮时跳转？

Question

脚本使用逼真的重力使游戏对象跳跃并到达特定目标。 GameObject relative 跳转到目标，从而调整其轨迹。它在目标点移动时也有效。

当 GameObject 到达目标时，目标会跳到更高的位置 (position.y += 50) 并且 GameObject 会朝那里跳跃。因此，我们有一个“连续跳跃循环”。

脚本：

using UnityEngine;
using System.Collections;

public class Jumper : MonoBehaviour
{
    public Vector3 _gravity = 9.8f * Vector3.down;
    public bool stillJumping = true;
    public GameObject Target1;

    public void SetVelocityToJump(GameObject goToJumpTo, float timeToJump)
    {
        StartCoroutine(jumpAndFollow(goToJumpTo, timeToJump));
    }

    private IEnumerator jumpAndFollow(GameObject goToJumpTo, float timeToJump)
    {
        var startPosition = transform.position;
        var targetTransform = goToJumpTo.transform;
        var lastTargetPosition = targetTransform.position;
        var initialVelocity = getInitialVelocity(lastTargetPosition - startPosition, timeToJump);

        var progress = 0f;
        while (progress < timeToJump)
        {
            progress += Time.deltaTime;
            if (targetTransform.position != lastTargetPosition)
            {
                lastTargetPosition = targetTransform.position;
                initialVelocity = getInitialVelocity(lastTargetPosition - startPosition, timeToJump);
            }

            transform.position = startPosition + (progress * initialVelocity) + (0.5f * Mathf.Pow(progress, 2) * _gravity);
            yield return null;
        }

        OnFinishJump(target, timeToJump);
    }

    private void OnFinishJump(GameObject target, float timeToJump)
    {
        if (stillJumping)
        {
            Vector3 temp1 = Target1.transform.position;
            temp1.y += 12.5f;
            Target1.transform.position = temp1;
            StartCoroutine(jumpAndFollow(target, timeToJump));
        }
    }

    private Vector3 getInitialVelocity(Vector3 toTarget, float timeToJump)
    {
        return (toTarget - (0.5f * Mathf.Pow(timeToJump, 2) * _gravity)) / timeToJump;
    }
}

使用上面的脚本，游戏对象总是从它到达的位置跳转。这就是我所说的“连续跳跃循环”的意思

JumpTarget 的脚本：

public class JumpTarget : MonoBehaviour
{
    public Jumper Jumper;
    public float TimeToJump;

    public void Start()
    {
        if (Jumper != null) Jumper.SetVelocityToJump(gameObject, TimeToJump);
    }
}

这里的问题是：我们怎样才能让 GameObject 继续在 (Input.GetMouseButtonUp(0)) 上跳跃每次（不仅仅是第一次跳跃）？我不能安静地想通出去。

下面的代码应该可以实现这一点，但 GameObject 甚至不跳转！

if (Input.GetMouseButtonUp(0) && Jumper != null) Jumper.SetVelocityToJump(gameObject, TimeToJump);

我尝试调试，但不幸的是，我的 Unity 编辑器每次都崩溃。

编辑：我抱怨我的脚本按应有的方式运行 (Input.GetMouseButtonUp(0) 如果我的脚本适合您，请上传一个示例项目，其中我的脚本可以正常工作，作为答案。我怀疑我的其他脚本正在干扰...谢谢。

如果您想“继续”跳跃，请使用GetMouseButton(...) 而不是GetMouseButtonDown(...)，因为后者只会触发一次。

using UnityEngine;
using System.Collections;

public class Jumper : MonoBehaviour
{
    public Vector3 _gravity = 9.8f * Vector3.down;
    public GameObject Target1;

    public void SetVelocityToJump(GameObject goToJumpTo, float timeToJump)
    {
        StartCoroutine(jumpAndFollow(goToJumpTo, timeToJump));
    }

    private IEnumerator jumpAndFollow(GameObject goToJumpTo, float timeToJump)
    {
        var startPosition = transform.position;
        var targetTransform = goToJumpTo.transform;
        var lastTargetPosition = targetTransform.position;
        var initialVelocity = getInitialVelocity(lastTargetPosition - startPosition, timeToJump);

        var progress = 0f;
        while (progress < timeToJump)
        {
            progress += Time.deltaTime;
            if (targetTransform.position != lastTargetPosition)
            {
                lastTargetPosition = targetTransform.position;
                initialVelocity = getInitialVelocity(lastTargetPosition - startPosition, timeToJump);
            }

            transform.position = startPosition + (progress * initialVelocity) + (0.5f * Mathf.Pow(progress, 2) * _gravity);
            yield return null;
        }

        OnFinishJump(target, timeToJump);
    }

    private void OnFinishJump(GameObject target, float timeToJump)
    {
        if (Input.GetMouseButton(0))
        {
            Vector3 temp1 = Target1.transform.position;
            temp1.y += 12.5f;
            Target1.transform.position = temp1;
            StartCoroutine(jumpAndFollow(target, timeToJump));
        }
    }

    private Vector3 getInitialVelocity(Vector3 toTarget, float timeToJump)
    {
        return (toTarget - (0.5f * Mathf.Pow(timeToJump, 2) * _gravity)) / timeToJump;
    }
}

public class JumpTarget : MonoBehaviour
{
    public Jumper Jumper;
    public float TimeToJump;

    public void Start()
    {
        if (Jumper != null && Input.GetMouseButton(0)) Jumper.SetVelocityToJump(gameObject, TimeToJump);
    }
}
