enable network to listen to command coming from outside

Hi all,

I don’t know if it is Blueprint related, but if not thank you to point me in the right direction.

I am developping a simulation, that will need to be controlled by an other pc.

To make it simple : the simulation will be on a quickass machine.

But to launch it, and send some commands (could be bound to certain keys, like Spacebar do something, E an other thing, etc…), it will come from an other PC.
It is not a game per se, so no player to controls. Just events to be triggered.

How can I do that? The simulation is done and the events currently linked to keys. How can I open it to be controlled from outside.

Any input appreciated.

Thank you in advance
