一個小的幫助腳本，用于在運行時在場景視圖和游戲視圖中為盒子碰撞器著色，即使沒有選擇帶有碰撞器的游戲物件。
我要添加的問題或另一個功能是在列舉中選擇模式 DrawOnBoth 時，它將在場景視圖視窗中以紅色繪制，在游戲視圖視窗中以綠色繪制。
現在，當模式為 DrawOnBoth 時，Windows 場景視圖和游戲視圖都以綠色繪制。

uj5u.com熱心網友回復：
以下條件將SceneView和GameView分開。如果上面的代碼都沒有問題，答案就是這樣。
DrawGizmosOnRunTime(SceneView.currentDrawingSceneView() ? Color.red : Color.green);
