Said method also includes overall situation bag, and it does not need to be configured to involved promptly visible for other all bags automatically;
Said method also includes the bag table of unified lua script file name to bag, is used for bag is retrieved;
Said method has also defined following script file and has loaded flow process:
1) search the script file that need to load whether in the bag table, then jump to 6 in this way), as otherwise continue next step;
2) newly-built bag, and distribute ID to add the bag table;
3) whether inspection includes other bag, as otherwise jump to 6), then continue next step in this way;
4) load involved bag;
5) parents with involved bag adding current pack shows;
6) loading scripts file.
As a kind of improvement of above technical scheme, said method has also been introduced overall bag, and the said overall situation encapsulates and is configured to need do not comprised by other bag promptly is that other all bags are visible automatically.
As a kind of improvement of above technical scheme, said method comprises following filename finding step:
1) search in the name table in current pack earlier, find and then finish to search, the person does not continue next step;
2) in overall situation bag, search, find and then finish to search, the person does not continue next step;
The name table of the bag of 3) successively parents table being quoted is searched.
As a kind of improvement of above technical scheme, wherein search and adopt the traversal rule of dark search earlier.
With respect to prior art, lua script management method proposed by the invention has the following advantages:
1.lua script file all is carried in the same lua virtual machine, has guaranteed the internal memory service efficiency and has carried out efficient;
2. different lua script files is separate, and the object of the same name in the different files can not conflict mutually;
3. different lua script files can carry out communication through the specific mechanism shared data;
4. though the lua virtual machine is transformed, is still kept compatible in the grammer aspect.

Embodiment
Technical scheme of the present invention utilizes a kind of machine contracting system to manage each lua script file, and each different lua script file is corresponding to a bag, and wherein bag is the container of object name in a kind of program, and object then is the entity of data structure or function in the program.Each bag identifies (ID) with a numeral, in a preferred embodiment, bag be designated one more than or equal to 0 integer, promptly begin to increase progressively from numeral 1.
Each bag all has oneself independently name space, the i.e. mapping table of object name and object.The present invention also includes the bag table of a unified filename to bag, and it is a kind of mapping table of key-value type, is used for the mapping of script file name to corresponding bag, is used in the present invention bag is retrieved.
In the present invention, encapsulate be configured to separate, but can through certain applications program interface (API) the bag between set up vertical linkage, this vertical linkage is called and comprises (include).That is to say that include is the address of a kind of vertical linkage between bag and the bag, also is to set up the used API name of this connection.Specifically, (include) bag A if bag B comprises, the object that then wraps A is visible for bag B; But can not set up backward linkage simultaneously,, then not allow to wrap A and comprise B if promptly bag B has comprised bag A.A bag can be comprised by a plurality of bag, also can comprise a plurality of bags.But a bag only knows and oneself comprised those bags, and do not know ownly to be comprised by those bags.Specifically as shown in Figure 1.
In addition, the present invention also includes a special overall situation bag, and Digital ID is 0, need not comprised promptly visible for other all bags automatically by other bag.
Specifically, all have during each wraps two kinds of key data structure arranged:
1. father (parents) table: a kind of by the bag set table of using, the member is by the ID of the bag of the Include of current pack institute, is used to preserve the ID of the bag that current pack comprises in the present invention;
