unity 中Canvas MatchHeight
设置了
UI Scale Mode = Scale With Screen Size,
Reference Resolution = X 1334, Y 750,
Screen Match Mode = Match Width Or Height,
Match = Width 0, Height 1,
---------------------------------------
获取屏幕实际宽度.(RectTransform 在Canvas中填满时的宽度)
1 this.RealHeight = 750f; 2 this.RealWidth = this.RealHeight / (float)Screen.height * (float)Screen.width; 3 UnityEngine.Debug.LogFormat("real: width:{0} height:{1}", this.RealWidth, this.RealHeight);
