Window Layers and LevelsWindows can be placed on the screen in three dimensions. Besides horizontal and vertical placement, windows are layered back-to-front within distinct levels. Each application and document window exists in its own layer, so documents from different applications can be interleaved. Clicking a window to bring it to the front doesn’t disturb the layering order of any other window. A window’s depth in the layers is determined by when the window was last accessed. When a user clicks an inactive document or chooses it from the Window menu, only that document and any open uti ...继续阅读 (32)

应朋友之邀，写一点页游转手游的梗概，若有其他未提及之处，还望各位多多赐教！第一阶段：必须做的事情1、排查GCAlloc (new 的调用)原因:频繁的GCAlloc 会导致C#自身的GC操作。GC操作在移动设备上耗时很高，最差的情况下可以导致每秒都会卡顿数百毫秒;标准:常态下每帧0内存分配调用经验：1、杜绝foreach / unity的BUG，enumerator(boxing/unboxing)2、杜绝Linq; (各种自动生成的delegate对象);3、杜绝Reflection;4、Dictionary 不得使用 Enum 作为key (boxing/unboxing)5、可能的话，尽量使用ref传valuetype;(不是很重要，有了更好)2、Shader重写原因:1、内存占用。移动设备上，贴图的压缩格式不一样,一般使用 ETC或PVRTC 硬件压缩格式。这两种贴图都不支持Alpha通道. 使用ETC/PVRTC,即使使用2张同等分辨率的图(a+rgb),也能使贴图大小降至1/2--1/4;如果使用原始带alpha通道的贴图格式兼容老shader，会导致极大的内存占用。2、像素填充率。移动设备显卡的像素带宽偏低，几乎要杜绝透明顶点色。各种多层alphaBlend做出的效果也要想变通的办法。否则发热量下不来，FPS上不去。标 ...继续阅读 (45)
