Week05_一般Unity專案轉UnityVR版本_呂登祐

其實Unity傳統專案跟VR的差別就在視角及contorller不同上，以下範例將為個位作介紹，如何把VR攝影機camera套用在一般專案上的camera上，及contorller控制器套用在Vive手把上。

SeasawPC Asset簡介

MainCamera
Floor
Rigidbody
Use Gravity: false
Is Kinemaic: true
Bearing
Board
Rigidbody
Freeze Position: x,y,z
中心點不移動
Freeze Rotation: x,y
X軸與y軸不可旋轉, z軸可旋轉

Person A 與 B
Rigidbody
Mass: 70
Use Graity: true
Fixed Joint
Connected Body: Board(Rigidbody) 固定連結在board上
Box Collider
Ground A 與 B
Empty
Box collider
Trigger: true
Reversion Script
以改變質量來使Board搖擺

week06

到s205實作
用手把偵測產生設定好的prefabs物件
然後就可以做出類似畫畫的效果

.

程式碼如下
using UnityEngine;
using System.Collections;
using Valve.VR;

public class Create : MonoBehaviour {

public SteamVR_TrackedObject rightController;
public GameObject redCube;
public GameObject blueCube;
public GameObject box;
// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
var device = SteamVR_Controller.Input ((int)rightController.index);
if (device.GetPressDown (SteamVR_Controller.ButtonMask.Trigger)) {
Instantiate (redCube, rightController.transform.position, rightController.transform.rotation, box.transform);

}
if (device.GetPress (SteamVR_Controller.ButtonMask.Trigger)) {
Instantiate (blueCube, rightController.transform.position, rightController.transform.rotation, box.transform);

}
if (device.GetPressUp (SteamVR_Controller.ButtonMask.Trigger)) {
foreach (Transform child in box.transform) {
GameObject.Destroy (child.gameObject);
}
}
}
}

第二個實作
是要把場景中的物件抓取起來
按下版機就可以當手一樣把物件抓取起來

程式碼如下:
using UnityEngine;
using System.Collections;

public class Touch : MonoBehaviour {

public SteamVR_TrackedObject leftController;
bool isTouch=false;
// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
var device = SteamVR_Controller.Input ((int)leftController.index);
if (device.GetPressDown (SteamVR_Controller.ButtonMask.Trigger)) {
isTouch = true;
}
if (device.GetPressUp (SteamVR_Controller.ButtonMask.Trigger)) {
isTouch = false;
}
}
void OnTriggerStay(Collider other){
if (other.tag == "catch" && isTouch) {
other.transform.position = this.transform.position;
}
}
}

第三個實作(回家作業)

將模型套入
讓手把在實境內是以光劍模組顯示

成功後就可以像絕地武士一樣揮舞光劍了!!!!

程式碼如下:
using UnityEngine;
using System.Collections;

public class LightSaberContol : MonoBehaviour {

public SteamVR_TrackedObject Controller;
public GameObject centerBeam;
lightsaber saberOn,saberCenterBeam;

void Start () {
saberOn = this.GetComponent<lightsaber> ();
saberCenterBeam = centerBeam.GetComponent<lightsaber> ();

}

// Update is called once per frame
void Update () {
if (Controller == null)
return;
var device = SteamVR_Controller.Input ((int)Controller.index);
if (device.GetPressDown (SteamVR_Controller.ButtonMask.Grip)) {
saberOn.saberon = !saberOn.saberon;
saberCenterBeam.saberon = !saberCenterBeam.saberon;
print ("Grip");
}

}
}
