pause

Pauses the current engine. All the resources of the engine will remain in the memory, however the engine will not consume any processing power. Call unpause to revert the effect. This method is useful when you want to save processing power resources when the engine is inactive in your current UI. It is also useful, when you have multiple engine instances: we highly recommend that you always keep 1 active engine at a time. When switching the current active engine, call pause on the remaining engine instances.
