* Changes to the script engine:
- script ends when run_func can't find the buildin command. (script engine error) - run_script_main doesn't change RERUNLINE to RUN automatically, the buildin command that set it is responsible for that now. The buildin command can use this to detect a rerun. - created functions to alloc/free a script_state. git-svn-id: https://svn.code.sf.net/p/rathena/svn/trunk@13426 54d463be-8e91-2dee-dedb-b68131a5f0ec

* Changes to the script engine: [FlavioJS]
|
||||
- script ends when run_func can't find the buildin command. (script engine error)
|
||||
- run_script_main doesn't change RERUNLINE to RUN automatically,
|
||||
the buildin command that set it is responsible for that now.
|
||||
The buildin command can use this to detect a rerun.
|
||||
- created functions to alloc/free a script_state.
|
||||
2008/12/28
|
||||
* Added missing command #delitem. [SketchyPhoenix]
|
||||
* Fixed charcommand behavior where those that can accept a name with no additional parameters
