An Authoring Tool for Flash Games in ActionScript3.0

We present a tool for authoring interactive Flash games, which consists of its front-end graphical interface and a newly developed translator into Flash via Action Script3.0. The main feature is that the behaviors of characters are described in terms of state transition diagrams. Each state has a picture and activities. The picture represents appearance of the character in that state. The activities can be selected out of a set of performances such as relocation of the character and generation of other characters. A transition is conditioned in terms of events such as mouse click and collision with other characters. The graphical editor of state-transition diagrams built in this tool is so easy to manipulate that even children can compose interactive Flash games.
