Unity PhysicsScene測試

應該是unity 2018.3中加入的功能，對象能夠放置於不一樣的物理場景中。

一個Scene對應一個物理場景(PhysicsScene)，若想放入獨立的物理場景測試建立一個Scene便可。見下圖gif。

 

若測試模擬功能，須在Physics中關閉自動模擬。腳本以下：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;

public class PhysicsSceneDemo : MonoBehaviour
{
    public GameObject[] simulationObjects;
    public float physicsSceneTime;

    float mLastPhysicsSceneTime;
    Scene mPhysicsTestScene;
    PhysicsScene mPhysicsScene;


    void Start()
    {
        mPhysicsTestScene = SceneManager.CreateScene("PhysicsTestScene");
        mPhysicsScene = mPhysicsTestScene.GetPhysicsScene();

        for (int i = 0; i < simulationObjects.Length; i++)
            SceneManager.MoveGameObjectToScene(simulationObjects[i], mPhysicsTestScene);

        Physics.autoSimulation = false;
    }

    void Update()
    {
        if (physicsSceneTime != mLastPhysicsSceneTime)
        {
            mPhysicsScene.Simulate(physicsSceneTime);
            mLastPhysicsSceneTime = physicsSceneTime;
        }
    }

    void OnDestroy()
    {
        SceneManager.UnloadSceneAsync(mPhysicsTestScene);
        Physics.autoSimulation = true;
    }
}
