The maximum x-coordinate value of the RectInt. This value is exclusive.
The RectInt.width is the difference between xMax and RectInt.xMin. If you set an xMax less than the current RectInt.xMin, then RectInt.width becomes negative. xMax and RectInt.xMin values are normalized prior to being returned such that xMin is always the smallest of the two values and xMax the largest. For example, a RectInt r created as RectInt r = new RectInt(0, 0, 10, 10); and later assigned r.xMax = -5 returns RectInt.width of -5, RectInt.xMin of -5, and xMax of 0. The xMax value is one greater than the largest x-coordinate contained in the RectInt. For example, a RectInt spanning x-coordinates 0–3 has an xMax of 4.
