vrtk 3.2.1 知識點記錄

 

獲取左右手柄物體：

GameObject handObj = VRTK_DeviceFinder.GetControllerLeftHand();
GameObject handObj = VRTK_DeviceFinder.GetControllerRightHand();

獲取左右手柄設備：

Device deciveLeft = SteamVR_Controller.Input((int)VRTK_DeviceFinder.GetControllerIndex(VRTK_DeviceFinder.GetControllerLeftHand()));

Device deciveRight = SteamVR_Controller.Input((int)VRTK_DeviceFinder.GetControllerIndex(VRTK_DeviceFinder.GetControllerRightHand()));

手柄按鍵：

SteamVR_Controller.ButtonMask.System;
SteamVR_Controller.ButtonMask.ApplicationMenu;
SteamVR_Controller.ButtonMask.Grip;
SteamVR_Controller.ButtonMask.Touchpad;
SteamVR_Controller.ButtonMask.Trigger;

手柄上的按鍵是否按下：

if(device.GetPressDown(SteamVR_Controller.ButtonMask.Trigger)) 
{  
            Debug.Log("用press按下了 “trigger” “扳機鍵”");  
}  
 if (device.GetPress(SteamVR_Controller.ButtonMask.Trigger))  
 {  
        Debug.Log("用press按了 “trigger” “扳機鍵”");  
 }  
if (device.GetPressUp(SteamVR_Controller.ButtonMask.Trigger))  
{  
         Debug.Log("用press鬆開了 “trigger” “扳機鍵”");  
}

圓盤各個方向判斷：

       //觸摸觸發  
        if (device.GetTouchDown(SteamVR_Controller.ButtonMask.Touchpad))  
        {     
            Debug.Log("按下了 “Touchpad” “ ”");  
              
            //方法返回一個座標 接觸圓盤位置  
            Vector2 cc = device.GetAxis();  
            Debug.Log(cc);  
            // 例子：圓盤分成上下左右  
            float jiaodu = VectorAngle(new Vector2(1, 0), cc);  
            Debug.Log(jiaodu);  
            //下  
            if (jiaodu > 45 && jiaodu < 135)  
            {  
                Debug.Log("下");  
            }  
            //上  
            if (jiaodu < -45 && jiaodu > -135)  
            {  
                Debug.Log("上");  
            }  
            //左  
            if ((jiaodu < 180 && jiaodu > 135) || (jiaodu < -135 && jiaodu > -180))  
            {  
                Debug.Log("左");  
            }  
            //右  
            if ((jiaodu > 0 && jiaodu < 45) || (jiaodu > -45 && jiaodu < 0))  
            {  
                Debug.Log("右");  
            }  
        }  
        //按動觸發  
        if (device.GetPressDown(SteamVR_Controller.ButtonMask.Touchpad))  
        {  
            Debug.Log("用press按下了 “Touchpad” “ ”");  
        }  
         
    }  
 
    //方向圓盤最好配合這個使用 圓盤的.GetAxis()會檢測返回一個二位向量，可用角度劃分圓盤按鍵數量  
    //這個函數輸入兩個二維向量會返回一個夾角 180 到 -180  
    float VectorAngle(Vector2 from, Vector2 to)  
    {  
        float angle;  
        Vector3 cross = Vector3.Cross(from, to);  
        angle = Vector2.Angle(from, to);  
        return cross.z > 0 ? -angle : angle;  
    }
