因此，您不必计算所有这些行，崩溃似乎是由以下代码部分引起的：
    for(int i = 0; i < keys.length; i++){
        String key = keys[i].toString();
        Item item = GameRegistry.findItem(
                //the following line is the one in the crash report
                key.toString().substring(0, key.indexOf(":")), 
                key.toString().substring(key.indexOf(":") + 1));
                //these are modID and item name, without the colon
        addAspects(item, p.getProperty(key));

    }

for（int i=0；i
它很可能在空行上崩溃，因为它找不到：
字符。在创建项目的行上方添加此行：
if (key.length() == 0) continue;


另外，您不需要调用key.toString（）
：只要key
就可以了。它已经是一个字符串。
您的键之一在执行过程中不包含任何“：”，因此
key.toString（）.substring（0，key.indexOf（“：”）
计算为导致错误的key.substring（0，-1）

检查是否存在“：”b
Item item = GameRegistry.findItem(
            //the following line is the one in the crash report
            key.toString().substring(0, key.indexOf(":")), 
            key.toString().substring(key.indexOf(":") + 1));
            //these are modID and item name, without the colon

 Item item = GameRegistry.findItem(
            //the following line is the one in the crash report
            key.toString().substring(0, key.indexOf(":")), 
            key.toString().substring(key.indexOf(":") + 1));
            //these are modID and item name, without the colon
  // nothing found, assume it's a block
  if(item == null) {
      Block block = GameRegistry.findBlock(key.toString().substring(0,key.indexOf(":")),

      if(block != null) {
