unity重新加载场景 我已经找遍了互联网，但我还是找不到解决我的问题的办法

我已经找遍了互联网，但我还是找不到解决我的问题的办法。我正在尝试创建一个游戏，它有3个场景:游戏开始，主要和游戏结束。

问题是，当试图从其他场景加载主要关卡时，它不会做它必须做的事情(例如跳转)3D道具，并且场景本身是滞后的。当我尝试只加载主场景时，它可以正常工作unity重新加载场景，但在角色死后，场景重新加载后，它又开始滞后unity重新加载场景游戏素材，我无法跳转或做任何它应该做的事情。

你知道问题出在哪里吗？

 using UnityEngine;
	using System;
public class Player : MonoBehaviour
{
	// The force which is added when the player jumps
	// This can be changed in the Inspector window
	public Vector2 jumpForce = new Vector2(0, 300);
	private bool shouldJump = true;
	// Update is called once per frame
	private float jumpThreshold = 0.5f;
	private float previousJumpTime;
	void FixedUpdate ()
	{
		// Jump
		float mc = MicControl.loudness;
		//Debug.Log (mc);
		if (mc>1.3f && shouldJump)
		{
			shouldJump = false;
			previousJumpTime = Time.time;
			GetComponent().velocity = Vector2.zero;
			GetComponent().AddForce(jumpForce);
		}
		if (!shouldJump) 
		{
			if(Time.time-previousJumpTime>jumpThreshold)
			{
				shouldJump = true;
			}
		}
		// Die by being off screen
		Vector2 screenPosition = Camera.main.WorldToScreenPoint(transform.position);
		if (screenPosition.y > Screen.height || screenPosition.y < 0)
		{
			Die();
		}
	}
	// Die by collision
	void OnCollisionEnter2D(Collision2D other)
	{
		Die();
	}
	
	void Die()
	{
		Application.LoadLevel ("main");
}
}
