Sorting layers draw in order of definition. When you add other layers (in Edit | Project Settings | Tags and Layers), Unity draws out any object it finds on the Default layer first (then Order in Layer takes over, and then the Transform’s Z position value) , then Background, then Pl...

rather than having to divide pixels by 2. So I can easily place an object in the middle of the screen by using (.5, .5) as its position. World space refers to the absolute positioning of an object in a game based on three coordinates, (0, 0, 0). All top-level game objects in...

屏幕后处理效果(screen post-processing effects)常用于实现屏幕特效 ,可以利用渲染纹理实现一些屏幕后处理效果 屏幕后处理:在渲染完整个场景得到屏幕图像后,再对这个图形进行操作,实现各种屏幕特效,如景深(Depth of Field)、运动模糊(Motion Blur)... 12.1 建立一个基本的屏幕后处理脚本系统 ...
Transform a screen space point to a position in the local space of a RectTransform that is on the plane of its rectangle.屏幕空间点转换为矩形变换内部的本地位置，该点在它的矩形平面上。The cam parameter should be the camera associated with the screen point. For a RectTransform in ...
