The invention discloses an interaction method and device of behavior data. The method comprises following steps: detecting first behavior data generated by an object during simulating flight motion; under the case that the first behavior data is detected, determining whether or not the speed data of the first behavior data satisfies a preset condition; if it is determined that the speed data satisfies the preset condition, controlling a virtual role corresponding to the object to execute a first preset flight behavior under a preset scene at a first preset speed, wherein the first preset speed is corresponding to the speed data. By means of the method and device of the invention, the technical problem that the difference between the object behavior and virtual role behavior is large in the prior art is solved.
