unity3d创建一个移动的平台

平台游戏的创建代码总结如下，物理组件设置好，速度设置好，直接看代码

using UnityEngine;
using System.Collections;

public class MovingPlatform : MonoBehaviour {
    [SerializeField]
    Transform platform;

    [SerializeField]
    Transform startTransform;

    [SerializeField]
    Transform endTransform;

    [SerializeField]
    float platFormSpeed;

    Vector3 direction;
    Transform destination;

    // Use this for initialization
    void Start () {
        SetDestination(startTransform);
    }

    void FixedUpdate() {
        platform.GetComponent<Rigidbody>().MovePosition(platform.position + direction * platFormSpeed*Time.fixedDeltaTime);
        if (Vector3.Distance(platform.position, destination.position) < platFormSpeed*Time.fixedDeltaTime)
        {
            SetDestination(destination == startTransform ? endTransform : startTransform);
        }
    }

    void OnDrawGizmos() {
        Gizmos.color = Color.green;
        Gizmos.DrawWireCube(startTransform.position,platform.localScale);

        Gizmos.color = Color.red;
        Gizmos.DrawWireCube(endTransform.position, platform.localScale);
    }

    void SetDestination(Transform dest) {
        destination = dest;
        direction = (destination.position - platform.position).normalized;
    }
}
