如何停止二手手指在Unity3D中操縱gui操縱桿的位置

Question

我一直致力於Unity3D中的3D移動應用程序，但最近遇到了問題。我有一個操縱桿，可以讓我的角色走路。操縱桿是一種gui紋理。我設置了邊界，因此無法在屏幕上移動操縱桿。它的設置使得當你的手指移動到邊界之外時，操縱桿將盡可能遠地移動，當你將手指移回時，手指會繼續移動。這很好，除了我要設置它以便沿着屏幕右側移動另一個手指來旋轉相機。當一個手指放在操縱桿上，並將另一個手指放在屏幕的右側時，會發生該問題。當我沿着屏幕右側移動一個手指時，操縱桿被重置！這是我的代碼...請幫助！

Answer 1

簡單的解決方案是存儲觸摸你的左邊fingerId一個變量說leftId當它擊中GUITexture，做同樣的右fingerId說rightId。現在當你檢查左手柄上的觸摸時，檢查Input.touches[i].fingerId != rightId和右手柄的類似檢查Input.touches[i].fingerId != leftId。

我也遇到過這個問題，並用它解決了它。

Answer 2

好的，我修好了！我不得不使用touch.fingerId而不是Input.GetTouch(i).fingerId 花了一段時間，但現在它已經開始運行！ :)
