Question

我正在創建一個小型演示，其中對象應根據來自 FOVE VR 耳機的眼動儀數據移動。

當我嘗試移動我的兩個對象（“Gaze Responder - Target”和“Gaze Responder - Fixation”）時：它們不移動，碰撞器停止工作。

我在 Unity3d (2017.4.40f1) 中有以下層次結構

以下代碼附加到 GazeContingenVisualField

    private float[] StimPos_H = new float[100];
    private float[] StimPos_V = new float[100];


    private Material materialTarget;

    // Use this for initialization
    void Start()
    {
        for (int i = 0; i < StimPos_H_deg.Length; i++)
        {
            StimPos_H[i] = Mathf.Tan(StimPos_H_deg[i] / 180.0F * Mathf.PI) * 20.0F;
            StimPos_V[i] = Mathf.Tan(StimPos_V_deg[i] / 180.0F * Mathf.PI) * 20.0F;

Answer 1

我不確定 FOVE 是如何工作的，但它是否以某種方式重置了“-Target”對象變換？

當我使用 AR 時，一些游戲對象（目標）無法移動，因為它們的變換是由庫處理的，並且試圖這樣做會導致各種奇怪的問題。

也許你想要移動的是實際的“Gazable Objects”（我知道這是 VR，但也許是同一個問題）。

如果有的話，在最后一個案例語句中，您將本地的固定 position 設置為 TargetGazeObj 的本地 position，但它們的坐標參考可能不同，因此您可能希望在那里使用全局 Z4757FE07FD492A38BE0EAZA760ED。

Answer 2

object 的轉換工作正常，但相關的閃電設置為 static，因此發射的 object 似乎沒有改變其 Z3DDA8757FE077FD468A。

必須禁用 Mesh Renderer 的 Lightmap Static 屬性
