The three-dimensional (3D) interactive animations and video games are so attractive that successful educational programming environments like Alice and Kodu Game Lab deal with 3D characters. Islay 3D is another educational programming environment of which feature is an intuitively comprehensive user interface in terms of state transition diagrams. Unfortunately its animation definition was too memory-hungry when played by the built-in interpreter. In this paper, we present a translator of the animation definitions of Islay 3D into ActionScript3 (AS3). Compiling the AS3 codes by way of Papervision3D, we obtain the 3D Flash animation file playable on the Flash platform. It will be shown that the memory and CPU usages will be much saved, quartered and halved, respectively, by virtue of the translator.
