Change Actor ownership?

Development Programming & Scripting Blueprint

If one has a multiplayer game, and their are some physics cubes lying around you can shoot and run into…

What should the clients and server do when a non-owner client not on the server runs into a cube?

It would appear that for accurate and instant interactivity, the client should ‘hit’ the cube, then tell the server about the hit.
The server owns the cube.

The best solution I think would be to change the ownership of the cube to the hitting client for a while, then change it back to the server after it settles down and stops moving.

Is this correct?

Is it the ‘best practices’ for an Unreal FPS Multiplayer game?

How does one ask the server to give up ownership?

Currently I have taken the First Person example project, made it multiplayer, changed the cubes to be physics mesh cubes.

In the game the server side works and if the server player hit a cube both the client and server see it move.

On the client side the client hits a cube and sees it move but the server is unaware it should move and does not see it move.

If the server player hits the moved cube, on the client i jumps to where the server thinks it is and then moves.

So once again,

What is the ‘best practice’ or recommended implementation?

If you create a BP Actor, set a static mesh to your cube, set the BP to replicate and replicate movement. It would stay in sync and replicate very well.

Yes it does stay replicated. But only in regards to what happens on the server.

What I’m asking is how to make the cube being hit replicate from a client to the server and then out to all the other clients in a multiplayer game.

I see one obvious solution:

  • When a player runs into an object, with a physics hit event, just send the event to the server and have the server ‘hit’ the replicated object to get it moving.

The problem is the net delay. Or is it a problem? Idk.

Thus I’m asking what is the usual way to handle a player running into a physics object on a client.

Well i have no problem with a dedicated server with 2 clients running around pushing cubes, it works fine for me.

Ok, who pushes the cube when a player runs into it?

Does a client player send an event?

Or does it get pushed by the players proxy actor on the server?
