Question

该脚本使用逼真的重力使GameObject跳转并到达特定目标。 GameObject将 relative 跳转到目标，从而调整其轨迹。当目标点移动时它也可以工作。

当GameObject到达目标时，目标会移到更高的位置（position.y += 50）并且GameObject会向那里跳跃。因此，我们有一个“连续跳跃周期”。

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，GameObject总是从它到达的位置跳转。这就是我所说的“连续跳跃周期”

JumpTarget的脚本：

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

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

问题在于：我们如何让GameObject每次都继续跳(Input.GetMouseButtonUp(0)) （而不仅仅是第一次跳转）？我无法安静搞清楚。

以下代码应该会发生这种情况，但GameObject甚至没有跳过！

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

我尝试过调试，但不幸的是，我的Unity编辑器每次都崩溃了。

编辑：我曾抱怨我的脚本正常工作 (Input.GetMouseButtonUp(0)如果我的脚本适合您，请上传一个示例项目，我的脚本正常运行，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(...)代替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);
    }
}

用户释放鼠标按钮时跳转？
