Skeletal Animation System
One of the coolest features of Crimson Legend is the characters’ Skeletal System. This is a system that constructs the characters’ bodies out of individual body parts. Each body part is an individual bitmap, and the characters are put together similar to dolls; that is, every part has a few “joints” where it fastens on to other parts.
When the characters move, these parts are rotated, and the result is smooth, semi-realistic animation that does not rely on individually drawn frames.
Download the Character Editor, the tool that has been used to create the characters and animations for the game (Place it in the game's root directory).
