类 Stat

En

The Stat class is a performance statistics panel that provides real-time updates on various performance metrics. The performance metrics included in the statistics are updated approximately every 1 second and are as follows:

FPS: Frames per second (FPS). The higher and more stable the value, the smoother the display.
Sprite: The count of all rendering nodes (including containers). Its size affects the efficiency of the engine's node traversal, data organization, and rendering. The smaller the value, the higher the game's operational efficiency.
DrawCall: This value is a crucial indicator of performance; the smaller the number, the higher the game's operational efficiency. It represents the approximate number of rendering batches submitted per second. Each preparation of data and notification to the GPU for rendering is called one DrawCall. Besides the time-consuming process of notifying the GPU to render, switching materials and shaders are also very time-consuming operations during each DrawCall.
CurMem: Represents memory and video memory usage; the smaller the value, the better.
Shader: indicating the number of Shader submissions per second. The smaller the value, the better.
Canvas: Composed of three values, which are only present after setting CacheAs, with a default of 0/0/0. From left to right, the meanings of the values are: the number of canvases redrawn per frame / the number of canvases with "normal" cache type / the number of canvases with "bitmap" cache type.

Stat是一个性能统计面板，可以实时更新相关的性能参数。参与统计的性能参数如下（所有参数都是每大约1秒进行更新）：

FPS(WebGL)：每秒显示的帧数。值越高且越稳定，画面越流畅。
Sprite：统计所有渲染节点（包括容器）的数量。这个数值的大小会影响引擎在节点遍历、数据组织和渲染方面的效率。数值越小，游戏运行效率越高。
DrawCall：此值是决定性能的重要指标，数值越小，游戏运行效率越高。表示大约每1秒的渲染提交批次。每次准备数据并通知 GPU 进行渲染的过程称为1次 DrawCall。在每次 DrawCall 中，除了通知 GPU 渲染比较耗时外，切换材质与 shader 也是非常耗时的操作。
CurMem：表示内存与显存的占用，数值越小越好。
Shader：表示每大约1秒 Shader 提交次数。数值越小越好。
Canvas：由三个数值组成，仅在设置了 CacheAs 之后才会有数值，默认为0/0/0。从左到右数值的意义分别为：每帧重绘的画布数量 / 缓存类型为"normal"的画布数量 / 缓存类型为"bitmap"的画布数量。
