Cocos2dx开发日志2-番外篇

由于采用了控制台显示log就有两个问题要解决

1. log的保存

由于没有找到比较好的重定向方案(既要显示到控制台又要保存到文件)

所以改用关闭时保存来实现(这样便不能处理异常关闭时的情况了不完美)

修改main.cpp的相应部分

#ifdef USE_WIN32_CONSOLE    CHAR_INFO *chiBuffer=(CHAR_INFO*)malloc(160*9999*sizeof(CHAR_INFO));    COORD coordBufSize={0};    COORD coordBufCoord={0};     SMALL_RECT srctReadRect={0};    coordBufSize.Y = 9999;     coordBufSize.X = 160;     srctReadRect.Bottom = 9999;    srctReadRect.Right = 160;     ReadConsoleOutput(GetStdHandle(STD_OUTPUT_HANDLE),chiBuffer,coordBufSize,coordBufCoord,&srctReadRect);    FILE *out=fopen("out.log","wb");int cur=0;int s=0;char buff[3];for(int i=0;i<160*9999;i++){        wchar_t c=chiBuffer[i].Char.UnicodeChar;if(c==0){break;}if(c<127){            s=1;            buff[0]=c;            fwrite(&buff,sizeof(char),1,out);        }elseif(c > 0x07FF){            s=2;            buff[0]=0xE0 | ((c >> 12) & 0x0F);            buff[1]=0x80 | ((c >> 6) & 0x3F);            buff[2]=0x80 | ((c >> 0) & 0x3F);            fwrite(&buff,sizeof(char),3,out);        }else{            s=2;            buff[0]=0x80 | ((c >> 6) & 0x1F);            buff[1]=0x80 | ((c >> 0) & 0x3F);            fwrite(&buff,sizeof(char),2,out);        }        cur+=s;if(cur>159){            fprintf(out,"\n");            cur=0;        }    }    fflush(out);    fclose(out);    FreeConsole();#endif

2. log的过滤

由于log本身不是采用我们的控件之类的来实现的所以只能做到颜色标记这步了

在AppDelegate.cpp中添加绑定的注册

绑定的代码

其中的颜色部分可以自行定义

对于android(logcat)部分可以忽略此设定
