你知道怎么了吗?游戏核心包括以下功能:
var game_core = function(game_instance){....};
添加到game_core.js的末尾:
module.exports = {
game_core : game_core
}
至games.js:
var game_core = require('./game_core').game_core(game_istance);
添加到game_core.js的末尾:
module.exports = {

至games.js:
var game_core = require('./game_core').game_core(game_istance);
需要节点中的模块不会将其内容添加到全局范围。每个模块都包含在自己的范围内,因此您必须: 然后在主脚本中保留对导出对象的引用:
var game_core = require('./game_core.js');
...
thegame.gamecore = new game_core( thegame );
