Recently simply played a bit cocos2d-js, with a template to write a code, found that the lower left corner of the numbers do not know how to remove, check the data also do not know where to modify.After a few explorations finally found ccdirector.js this file in Cocos2d's core package root directory. Find CC in the inside. Director._fpsimageloaded = True To change the true to false.--------------Found the original in Cocos2d.js modified more suitable:How to remove the three-line number (

VSync is the abbreviation of the vertical period (Vertical synchronization). The main idea is to set your FPS and display refresh rate up to the same time. The aim is to avoid a phenomenon called "tearing". I will describe these details again below.Each CRT display has its own refresh rate. The unit is Hz. The value is the number of times the monitor updates the screen per second. Different displays support different refresh rates at different resolut

First, I will explain two terminologies throughout the full text:
Frames per second (FPS)
FPS is the abbreviation of frames per second. In this context, it indicates the number of times display_game () is called per second.
Game speed
The game speed is the speed at which the game status is updated per second. In other words, the number of times update_game () is called

A recent thing to do is to display the frame rate, or FPS, in real time on the video. FPS is the abbreviation for frame per second, in Chinese meaning the number of frames per second. The development platform is vs2013+opencv2.4.9.FPS is the measurement of the amount of information used to save and display dynamic video. In layman's terms, it refers to the number
