Game Engine Extends The Research And Script Technology

Game engine is an important part of game designing and its improvement willenhance the efficiency of game designing. The script system of game engine takecharge of variation parts like log management, configuration management and so on.As the quickly improvement of game designing technique the script system withtraditional manner can not fit for designing. In this paper, we analyze three gameengines: 2D RPG type engine(《lord's sword saga》),mature 2D engine(WGScommerce game engine),excellent 3D engine(OGRE), and deeply research theirscript system also summarize their common ground and disadvantage.We put forward a new kind of manner: game engine extension script technique andanalyze the huge advantage with using this technique. We also introduce therealization method with example of Lua script language combined with OGRE gameengine.There are two parts of game engine extension script technique: the function ofextension script in game engine and the language characteristic of extension script.In traditional manner, the functions of script are too simple. It just only takes chargeof log management and configuration management. The script file is only used todisplay some information. The interpreter and relevant script are special in syntax.This make it has no language characteristic, limit the extension space of scriptsystem function.In new manner, we plot every function module of engine base on running timeefficiency. Script will not only deal with some basic affair, but also manage somemodule which request not so much capability in the running time. The main parts ofengine deal with those modules which in counter part. After extending the languagecharacteristic of script, we can realize lots of functions which we can't do before.At last, we validate the feasibility and advantage of extension script technique bydesigning two games using WGS engine and OGRE engine which are combinedwith extension script technique.
