腾讯云 技术升级10大核心产品年终让利>>>   

此类工具搜索过一些,都不要好用,于是决定自己实现一个。

大图集拆开为小图片,由于是工具,于此效率不太重要,直接用Cocos2dx随手写了一个。

基本思想是直接读取,然后把该SpriteFrame输出为文件即可

#include "cocostudio/CocoStudio.h"
#include "ui/CocosGUI.h"

Scene* HelloWorld::createScene()
{
	// 'scene' is an autorelease object
	auto scene = Scene::create();

	// 'layer' is an autorelease object
	auto layer = HelloWorld::create();

	// add layer as a child to scene
	scene->addChild(layer);

	// return the scene
	return scene;
}

// on "init" you need to initialize your instance
bool HelloWorld::init()
{
	// 1. super init first
	if (!Layer::init())
	{
		return false;
	}
	vector<string> files;

	const char *TEM_WORK_FILE_NAME = "filelist.txt";
	string path = "res";

	string cmd_txt = "cmd.exe /c  DIR  " + path + "  /S /B   >   ";
	cmd_txt += TEM_WORK_FILE_NAME;

	system(cmd_txt.c_str());

	fstream f;

	f.open(TEM_WORK_FILE_NAME, ios::in);

	vector<string> _queue;

	string buf;

	while (getline(f, buf))

		{
			//	file_path.replace('\\', '/');
			file_path[file_path.find("\\")] = '/';

		files.push_back(file_path);

	//	this->WriteToFile();
	f.close();
