The invention provides an event management method and system based on Unity. The method comprises the steps that an event management center presets an event processing template, wherein the event processing template comprises ID of an event and a callback function corresponding to the event; when the event management center monitors an event, whether the event is the event in the event processing template or not is judged according to the ID of the event; if not, the callback function corresponding to the event is obtained; the event processing template corresponding to the event is preset according to the ID of the event and the corresponding callback function. If the monitored event is the event preset in the event processing template, the callback function in the template is directly called to avoid duplicate definition of the event; if the monitored event is the event not contained in the event processing template, the event processing template is preset for the event, so that the call function in the event processing template can be directly used when the event is monitored next time.
