The invention discloses a ports interactive animation producing method. In the method, a layered frame is adopted to built a model for the interactive motion flow, namely in a state layer and in a motion layer. In the state layer, a finite state machine is built to simulate the conversion between the states in the interactive motion. In the motion layer, a mixed method is used to produce the motion choice according with the opposing situation between the present parts in an opposing state. For solving the problem that the data is captured by the single-part motion without the interactive action between the parts, the invention adopts a machine study and experience rule mixed method to capture and simulate the interactive action between the parts, the good effect is obtained, the produced animation has visual nature and trueness.
