在MoonWarriors例子中，这段代码有什么用？
var g_mainmenu =
//{src:s_loading},
{src:s_menu},
{src:s_logo},
{src:s_mainMainMusic},
{src:s_menuTitle},
{src:s_textureTransparentPack_plist},
{src: s_textureTransparentPack },
{src:s_helloworld}
];
var g_maingame =
//image
{src:s_cocos2dhtml5},
{src:s_gameOver},
{src:s_flare},
{src:s_arial14},
{src:s_explosion},
{src:s_textureOpaquePack},
//tmx
{src:s_level01},
//plist
{src:s_explosion_plist},
{src:s_textureOpaquePack_plist},
//music
{src:s_bgMusic},
//effect
{src:s_buttonEffect},
{src:s_explodeEffect},
{src:s_fireEffect},
{src:s_shipDestroyEffect},
// FNT
{src:s_arial14_fnt}
];
我自加的资源不填到这个数组中也没事，亲问他有什么用？
