Your save game file only consists of these objects? Then it's pretty easy. You can do it this way:

Code:

---

function saveEntity(fileHandle, ent)
{
	you = ent;
	file_str_write(fileHandle,your.name);
	file_str_write(fileHandle,delimit_str);
	file_var_write(fileHandle,your.x);
	file_var_write(fileHandle,your.y);
}

---

Now the loading function is the same, only backwards. You don't need to parse through any strings. The loop you are using with ent_next() is still the same as in your code.
