Hello, I’m doing a multiplayer game where the players have to finish a task in a Room so the door opens only for that client so the client can go to the next room. At first, I was trying to have a static mesh of a door and open it, but the door opens for both clients. So now I’m trying to do an invisible wall (box collider) that disables collision when a client finishes a task but I think I’ll have the same problem with the door. Any ideas on how could I solve this problem?
I’m only using blueprints.
Thank you.
There are collision channels in the project settings you can use for things like this.
I believe they are listed under “collision” but I don’t have UE open atm to check.
I see, I’m gonna check it right now.
Hello,
Thank you, is working exactly as I wanted it now.
For anyone interested or have the same problem this is my code.
I have a box trigger and a door (static mesh) I also add a new Collision Channel “InvisibleDoor”. So when a player overlaps the box first I check if is controlled locally. Then check if it has a BPI (I’m using Interfaces because I like it more this way). Then I get the unique Player ID. The Room will have an int-array of all the players that can pass, so I can easily decide which player can or not pass (the array has to be replicated). Then I just Find if the ID is in the array of players that can pass. If they can pass I make a call to the BPI again and set the collision on the BP_Player.
I’m not sure if I have to make an RPC there but it works with the RPC, I’ll check that later.
Now that I also have a Ref of the player when overlaps. Once the overlap ends I just call the BPI again so that in the next room, the player can not pass the door until that room adds it to their array.
Hello, sorry but I’m using only blueprints. My c++ skills are not that good and it would be even more difficult if I try to do multiplayer with my current c++ skills 
.Thank you for reply tho 
That function is also callable from blueprints.
