渲染流程记录

前一段时间搞清楚了cocos2dx的渲染流程今天好像有遗忘了不少细节果然好记性不如烂笔头还是不偷懒几下
渲染流程记录：
create (texturecache:addimage ,ccimage:initWithImageFile initWithImageData,texture2d:initWithImage) inittexture settexture&&setTextureRect( updateBlendFunc() setOpacityModifyRGB updateColor updateQuad setTextureCoords setVertexRect setContentSize) 设置完数据当一帧过去directory drawScene visit进行draw draw把当前对象加入渲染队列最后render进行渲染画出 render根据不同队列类型渲染的流程网上可以找到
还有用自己的shader一定要绑定的a_position,a_color,a_texturecoord应该是在texture2d里面用到
另外之前练习的为了方便查看弄出console也记录下免得以后到处找
main.cpp

#include "main.h"#include "AppDelegate.h"#include "cocos2d.h"USING_NS_CC;#define USE_WIN32_CONSOLEint APIENTRY _tWinMain(HINSTANCE hInstance,                       HINSTANCE hPrevInstance,                       LPTSTR    lpCmdLine,                       int       nCmdShow){    UNREFERENCED_PARAMETER(hPrevInstance);    UNREFERENCED_PARAMETER(lpCmdLine);#ifdef USE_WIN32_CONSOLE    AllocConsole();    CreateConsoleScreenBuffer(GENERIC_WRITE|GENERIC_READ,0,0,CONSOLE_TEXTMODE_BUFFER,0);    /*HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);    COORD size; size.X = 512 ; size.Y = 512;    SetConsoleScreenBufferSize(hOut,size);*/    freopen("CONIN$", "r", stdin);    freopen("CONOUT$", "w", stdout);    freopen("CONOUT$", "w", stderr);    HANDLE input   = GetStdHandle(STD_INPUT_HANDLE);            ::SetConsoleMode(input,ENABLE_ECHO_INPUT|ENABLE_PROCESSED_INPUT        |ENABLE_WINDOW_INPUT|ENABLE_MOUSE_INPUT|ENABLE_PROCESSED_OUTPUT|        ENABLE_WRAP_AT_EOL_OUTPUT|ENABLE_LINE_INPUT|0x0004|0x0040);#endif    // create the application instance    AppDelegate app;    int ret = Application::getInstance()->run();#ifdef USE_WIN32_CONSOLE    FreeConsole();#endif    return ret;}
