摘要：In order to solve the error of simulation result because of data loss in VR-Link traditional simulation framework, in this paper data transfer mechanism of instance attribute on VR-Link object class is researched in detail. Registration method of call-back function is given, and the key codes of relevant steps are published. The problem of data loss is solved by the call-back function of VR-Link.
