PROBLEM:
Just wanted to let anyone that is searching for an answer to a similar problem I had that there is an answer! The problem was that when opening the provided Krazy Karts uproject, I could get to about the Server Functions and Cheat protection section before things weren’t working, while using Enhanced Input.
First problem I had was that for some reason, whenever you started the game as a listen server with two characters, the character on the server seemed to have its pawn be unpossessed and you couldn’t control the car.
The second problem was that the client would not move on the server, even though the bindaction functions had ‘UFUNCTION(Server, Reliable, WithValidation)’ attached to it.
SOLUTION:
Fixing the first problem had me pretty much remaking the project from scratch, opening unreal engine and creating a new project, and then copying the code and stuff over, if you got stuck at the same point I did, it’ll take you maybe 20 or so minutes! That stopped the unpossessing of the pawn on the server.
The second problem had me making a wrapper function, as it seems that the “const FInputActionValue& Value” in the input of the function you use for BindAction was just not properly being sent over the network maybe. But what fixed it is, when calling the BindAction function, pass in a normal non-RPC function, and have the “const FInputActionValue& Value” as the input for the function as normal.
Then in the non-RPC function, have it call the RPC function using the actual value of the FInputActionValue (in my case, float). Don’t forget to add the mapping context as well! I’ll post some screenshots below! Hope these help save you the day or two it took me to figure it out!
