## Abstract

A method and computer system for dynamically updating a model associated to a simulated interactive object in an interactive computer simulation comprising a computer generated environment. In real-time, a simulated behavior of the simulated interactive object is provided considering the model associated thereto. After reception of a request to modify the model, a new model is determined and validated by computing a validation indicator. The validation indicator computation considers interrelated parameters associated to the model and simulated constraints associated to the computer generated environment. The model is then selectively and dynamically updated into a new model considering at least the validation indicator. Subsequently, in real-time, an updated simulated behavior of the simulated interactive object is provided correspondingly considering the model or the new model associated thereto.
