The invention relates to the field of video games and discloses a video game development system and a method of the video game development system. The number of compilations for a computer to compile video game executable program and the total calculation quantity of the computer are greatly reduced, the planning and artistic design principle can be more perfectly recovered, the game development period is shortened, and the development cost is reduced. The system comprises a file generating tool, a code automatic generator, a code developing tool, a compiler and a trigger editor, wherein the file generating tool is used for recording various events, conditions and behaviors needed to be used in the video games into a definition file; the code automatic generator is used for generating a framework code according to the definition file and an engine code base; the code developing tool is used for realizing various events, conditions and behaviors through concrete codes according to realization interfaces in the framework code, the compiler is used for compiling codes realized by the code developing tool into game programs; and the trigger editor is used for editing and storing a trigger combined by specified events, specified conditions and specified behaviors, and the trigger is used for the reading and the execution during the game program running.
